I just tried yet again, and one link worked while the other failed.
I just found a link for Safari 12.1.2 (Sierra):
in

No trace, however, of Safari 12 for High Sierra (Safari12.1.2HighSierraAuto.pkg or otherwise) in:
 



Thanks for that link.
  • I downloaded Safari 12.1.2 for Sierra.
  • Next, I did a full clone backup of my Sierra PCIe/SSD drive.
  • Rebooted using the external FireWire 800 Sierra clone. Wow... that was slow!
  • Installed Safari 12.1.2 on the external drive and checked to see if existing extensions (1Password, Ghostery, uBlock Origin) still worked. They did. Good news!
  • Noticed that the install replaced this previously deleted file: /System/Library/LaunchAgents/com.apple.SafariBookmarksSyncAgent.plist
  • And, as noted here before, my Mac Pro no longer sleeps, because the SafariBookMarksSyncAgent prevents it.
  • I will install Safari 12.1.2 on my working system and, again, delete the aforementioned plist.
I still cannot figure out why this agent is trying to sync bookmarks. I don't have an iCloud account but did use Apples predecessors: iTools, .Mac, MobileMe. Maybe there is some detritus left over from those tools?

You're welcome.

I don't have a direct answer regarding com.apple.SafariBookmarksSyncAgent.plist, but searching for "SafariBookmarksSyncAgent" yielded lots of gripes and grumbles (and perhaps some solutions).
 


Regarding passwords in Safari, there is a gotcha. I just received an email purporting to be from cafepress.com letting me know that there was a security breach. Rather than clicking on the link in the email, which seemed dubious, I logged into cafepress.com to change my password, with Safari automatically entering the login credentials.

I changed my password and Safari asked if it should remember it; I clicked on yes. Then I was notified that an email was being sent for confirmation. When I clicked on the link in the confirmation email, the resulting site would not accept the login credentials Safari supplied. I realized it wanted the old password, since until I confirmed, the new one wouldn't take effect. Unfortunately, I didn't know the old password. Fortunately, 1Password did, so I could log in via 1Password, and then was notified that the changes had taken place.

It all makes sense in a strange way, but I'm glad I have a second password repository.

Personally, I never let a browser save my passwords, I keep them in 1Password. 1Password keeps a record of previous passwords for each site, so it is simple if I need to access the previous one. I hope you saved the new password in 1Password, as well as Safari.
 


I just stupidly updated to Safari 13.0.2, and it killed 1Password 6, which I had been using happily until about 10 minutes ago. I have a family license for 1Password 6, so I don't want to upgrade to version 7 and have to buy a license for each user, and I am not interested in subscriptionware.

That happened to me about a month ago. Sorry to say, you are SOL.

I managed to unhose myself. Undaunted, I located a copy of the Safari13.0.2Mojave installer and opened it up with Pacifist. I carefully inspected the installer to find every file that was installed. I located the corresponding files from a Carbon Copy Cloner backup I did a few days ago. I had to disable SIP first, Even after disabling SIP I was unable to delete Safari, so I had to use the following terminal commands:
cd /Applications
sudo rm -rf Safari.app/
then I replaced each file with the old one. Lo and behold, I have Safari 12.1.2 again, and 1Password is working happily. Whew, that was a close one!

Mozilla Provides Workaround for Firefox 70 Not Loading Sites
Mozilla acknowledged an issue affecting Firefox users after updating to the latest 70.0 release and preventing websites or page elements that use dynamic JavaScript from loading.

,,, Users who want to check if they're affected by this bug can go to Mozilla's self-diagnosis site for storage problems at https://firefox-storage-test.glitch.me/ according to Mozilla Software Engineer Andrew Sutherland.

If the "Good: Totally Working. (fullyOperational)" status is displayed for all subsystems on the diagnosis page you are not impacted by this issue. However, if there are any failure messages, your Firefox installation is bugged and there is a problem with the profile's storage.

Mozilla provides a temporary workaround for Firefox 70 not properly loading websites and page elements until a fix will be issued with a future release.

I was hoping to help a friend with severe recent vision problems customize Safari for easier reading, but my approach didn't work very well - making a custom CSS Style Sheet and selecting that in Preferences > Advanced > Style Sheet didn't override background color, even using the !important flag.

Has anyone dealt with this already who could offer some tips?

I did find this Firefox help page:


#accessibility #CSS #vision

If your friend is willing to use Chrome (or Chromium), then I would recommend Styler Pro.

I found that Firefox can override website colors, but I ran into some problems while testing, where changes weren't being recognized, and I had to jump through some hoops with about:config to reset Firefox back to defaults to get the right colors again.
 


I don't think this is related to the issue above, but I am beginning to feel doomed with respect to Firefox, trying to log into Flickr, using my updated credentials rather than the old Yahoo login.
This works in Safari, so no problem with e-mail and password. Try in Firefox, and I get the "Oops, something went wrong." dialog. Disable Firefox's content blocking and disable extensions that might interfere (uBlock Origin, Privacy Badger, Decentraleyes, HTTPS Everywhere) - same problem. Restarts with all add-ons disabled - same problem. Empty the cache, remove old Flickr cookies, still no dice.
But here's the thing: if I open a private browsing window, in which the above extensions are active, and Firefox's content blocking is active, I can log in. This must mean something, but I'm at a loss to know what!
Just for the sake of others who might run into the problem, I have finally solved it, although not all the details are clear to me.

Using the profile manager in Firefox, I created a new profile and found I could log in to Flickr normally. Another issue that had appeared, that of no images appearing in posts in a film photo sharing thread at a Leica forum, was also resolved.

Using Firefox Sync, I could re-import bookmarks and extensions, and things still worked normally. But as soon as I imported my settings that I had exported from uBlock Origin in my old profile, the problems all came back.

So I made yet another profile, and kept uBlock Origin pristine, and all is well. This suggests that uBlock Origin is not being completely switched off when disabled for those sites, nor in safe mode when no extensions are supposed to be enabled. Why it did not interfere in a Private Browsing window (with uBlock Origin enabled) is also unclear. Anyway, I'm happy to have avoided going back to Safari for now!
 


Just updated to Safari 13.0.4 and Amazon's "Look Inside" feature has been disabled without any changes on my part. I have pretty lenient settings for Amazon (not blocking pop-ups etc.), and I'm not on Amazon Smile, which was once a problem. Increasingly, Safari seems to be incompatible with other websites - I cannot use it for our payroll company or medical billing. Perversely, it works OK on United and Availity, which used to be a headache.

Hmm, I updated to Safari 13.0.4 yesterday (on High Sierra). Jumping to Amazon and randomly clicking on some books, the "Look Inside" feature is working fine for me.

And I have the website set to "Never Auto-Play" and "Block Pop-ups and Notify".
 


Am I the only one experiencing huge memory leaks in Firefox? Granted, it's usually happened when I've had loads of tabs open, but it just happened again tonight – and I noticed that I had fewer than ten tabs open at the time. Firefox was supposedly using 20 GB (in a system with only 16GB RAM installed).

The one common thread: no matter how many other apps I have open, quitting Firefox solves it. Every time.

Bonus question: Is there a way to see the memory usage of each app without there having to be a memory leak to bring the information up? This is another thing I miss about the classic Mac OS!

I use Firefox ESR all day everyday and don't see that. For what it's worth, I
  • don't use Facebook (or LinkedIn)
  • typically have just a few tabs open
  • block many ads and unwanted, hidden connections (e.g. using NoScript)
  • play videos/YouTube only in a different browser

Activity Monitor. Click the Memory tab and sort by the Memory column (you may need/want to go to the View menu and choose “All Processes” or other filtering options). You can also kill processes from that screen.
 


Thank you, Todd! I don't know why my eyes instinctively went to the bottom quarter of the window, with the Memory Pressure graph and total stats (which are still much harder to interpret than the classic MacOS!) and completely ignored the wealth of information above!
 



Since upgrading to macOS 10.15.2, clicking on links to various (rarely the same) URLs causes Safari (13.0.4) to prompt for a choice of files for style sheet. The file is already selected in Safari -> Preferences -> Advanced -> Style sheet, and is highlighted in the Finder window that Safari pops up. Why is Safari asking? Is there something amiss with my style sheet? It's been my style sheet since Safari 6.

This problem dates back to at least Mojave, and I have the same issue. I may have solved it, but further testing and time will be needed.
  • Change the Preferences to have no style sheet selected.
  • Quit Safari.
  • Copy the original style sheet and rename it.
  • Delete the old style sheet file,.
  • Add the new/copy with its new name in Preferences.
 



In the thread called "web browser security" here on MacInTouch, Ric recently posted about Mozilla banning nearly 200 malicious Firefox add-ons. This leads me to ask: Can anybody tell me if there is a safe Firefox add-on for downloading non-copyrighted YouTube videos? Occasionally I just want to download one of the free guitar lessons that people post so I can have it available off-line for practicing. Video DownloadHelper is a popular Firefox add-on, but I have no idea if it's totally free of malicious activity. Would appreciate any suggestions from the MacInTouch cognoscenti.
 


Can anybody tell me if there is a safe Firefox add-on for downloading non-copyrighted YouTube videos?
While it's not a Firefox add-on, rather a command line tool, I can highly recommend the open source youtube-dl.

Probably the hardest part for some folks would be installing it. Instructions can be found in the README.md file. After that, it's very simple to copy the URL of the page containing the video in Firefox and paste it into a command line in Terminal. youtube-dl can even automatically download all the videos in a playlist.

You bring up the issue of copyright infringement. If YouTube plays a video without being logged-in, then youtube-dl will be able to download it as well. This does not preclude people from uploading things to YouTube that should not be there for reasons of copyright. It is up to the copyright holder to ask YouTube to remove a video if it is unauthorized.
 


Can anybody tell me if there is a safe Firefox add-on for downloading non-copyrighted YouTube videos?
youtube-dl is definitely one of the most powerful, and it supports sites beyond its namesake too, like Facebook, Instagram, and Twitter videos.

However, for those allergic to the command-line, they might appreciate a nice GUI experience, and I've found 4K Video Downloader to be a great experience for that. I've been using it over a number of years.
 



I use the Video DownloadHelper Firefox add-on. I keep it disabled until I need it. Firefox has an Add-ons Manager toolbar icon (which resembles a jigsaw piece). To 'install' it, go to View > Toolbars > Customize and drag the icon from the main window to the toolbar. Position it where you want it. Now, instead of reaching your add-ons through several levels of preferences, you can get to them with one click. You can turn any of the add-ons on/off with the blue toggle on the right side.

All that said, Video DownloadHelper does 'encourage' you to download their app (at least they have in the past). You don't have to.
 


I use "Download Video", a standalone app and browser extension which is part of Parallels Toolbox, a package of over 30 little tools/utilities from Parallels, a company best known for their virtualization software. Parallels Toolbox can be purchased separately but is usually bundled with the virtualization software. I've tried at least a dozen "YouTube/Facebook" downloaders in the past, and the Download Video tool often succeeds where others fail, plus it gives you options over the size/quality of the downloaded file and can convert formats like WebM to mp4. There is a free 7-day trial available.
 




VLC has always allowed downloading of YouTube videos, though the method is a bit long-winded. The latest version (3.0.8) will not, however, because YouTube have changed some things at their end, and it confuses the .lua script included with VLC that permits downloading.

If you can't wait for the next version of VLC, there is a fix.
  1. Replace the script with a newer version from https://raw.githubusercontent.com/videolan/vlc/master/share/lua/playlist/youtube.lua
  2. Select all the text and paste into TextEdit. Save as youtube.lua wherever you like; you will be moving it in the next step anyway.
  3. You have to right-click on the VLC app and select Show Package Contents. The script you replace is in VLC/Contents/MacOS/share/lua/playlist.
Once you have re-opened VLC you should find downloading from YouTube works as before.
 


Thank you, everyone, for all the excellent suggestions. I've used VLC for a long time as a player but never knew it could also download videos. Thank you, Christopher. I got it to work with little effort, but the only drawback was I couldn't figure out how to make it download from YouTube at the resolution I wanted (480p for reasonable file size). There may be a way, but I haven't yet found it. I've decided to go with Downie. It's easy to install, intuitive to use, and lets me choose the resolution to download from YouTube. Thank you, Thomas. MacInTouch people are the best!
 


4K Video Downloader has been my primary video downloader tool for YouTube, etc., for some time. However, the latest version only runs on High Sierra (macOS 10.13) or higher, and I'm still running Sierra.

This coincides with a problem where 4K Video Downloader is suddenly quitting unexpectedly when I try to download videos from YouTube.

Question: Does anyone have recommendations for an alternate video downloader app, that is still supported under Sierra? Thank you in advance!
