Using firefox in linux mint 19.3 mate. Until firefox 97, I could control the size and color of the firefox scrollbars with a system CSS. Since a firefox update to version 98, firefox ignores those settings. Nothing has changed in my firefox settings, my about:config, or system settings. But now the scrollbars are barely visible low contrast narrow bars that are unpleasant to work with, and I can't figure out how to change this. suggestions? tnx

When I try to download a file, the download always fails. This happens no matter what website I'm downloading the file from (see screenshot 1).

This started happening within the last week or so. We are running versions 97 and above.

Firefox is configured to always ask where to save files to (see screenshot 2).

Write permissions to the user's Downloads folder is denied for reasons unrelated to this issue (see screenshot 3). When I re-enable write permissions, the problem goes away.

Has anyone else run into this problem? Is write access to the Downloads folder required now, even if Firefox is not configured to save files to that location? Thanks!

Why, with not very many active open windows, and just after opening, is FF using 175% of my CPU, not counting all the separate listings in my Activity Monitor. Plus it's using nearly all 16 GBs of my RAM. With every new update, I pray it will mean the browser will just work, and not use up all my computer's resources, but it just never does. Pretty soon, more & more of us will just give up on this browser, which used to work better, years ago, and has only gone downhill since.

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

I'm trying to recover a profile that has the most recent history, tabs and pinned tabs that I seem to have either lost or overwritten yesterday. I can try to reconstruct from my actual history but I don't remember everything I had open. I'm also not sure what to do with all the profiles that are associated with my browser. The version with my actual name is not the default and is an initial version I used on an older computer.A ny easy answers would be appreciated. It's frustrating that there is no way to contact them Mozilla directly.

Thanks

After experiencing some problems (saved tabs being empty, menus gone etc.) I read about restarting into troubleshoot mode ("Help"-"Troubleshoot mode" menu) which solved those problems (I believe "Troubleshoot mode" might be the same as "Refreshing" Firefox, from what I've read -correct me if I'm wrong) . I'm on Firefox 98.0.2 on a Mac.

Following that I quit Firefox and opened it again the normal way which I assume means it went into the normal mode as before, but I realized all my extensions were gone! Reading through some older postings I see they're in a profile named "legacy_BAK.profile", and in addition I have recent Time Machine backups, so any files aren't lost, but I guess the simplest way to fix this is to re-install my extensions -but most extensions (inside the "extensions" folder within the profile folder) only have a cryptic numbered name with and .XPI extension. So how can I find out which extensions I used to have, and better yet -is there a quick way to just install everything back again with a single click (installing it from the legacy profile folder, or just moving something over to the new folder etc.)?

The Motherboard on my Windows 7 gave up, however the SSD that it was on is still working properly.

I have seen it on an alternative Windows 7 computer.

I specifically wish to recover the the Bookmarks that is on the Mozilla Firefox browser, and also all of my emails on Mozilla Thunderbird.

I would be most grateful, if someone can please tell me how this can be done?

I recently made the switch to Firefox. I attempted to use the version downloaded from the internet, which I already had installed for a long time, but it would not open. I then used the version available on the Microsoft Store, which worked fine. Eventually, Firefox crashed and would not reopen. A message saying something along the lines of "Are you sure you want to start Firefox in safe mode?" would appear for a split second, and then close. I tried:

-Starting Firefox in safe mode, but nothing happened. -Restarting my computer. -Reinstalling Firefox. -Running as administrator. -Checking it is not blocked by antivirus. -Using the profile manager to create a new profile: The .zip file version opens but does not help, and the version opened by using the "firefox.exe -P" command in Run suffers from the same problem as the browser and opens for only a split second. -Attempting to boot my computer in safe mode with networking, however, the Microsoft Store listed Firefox as uninstalled, and the network menu would not display any networks so I could not reinstall it. -Searching for any Comodo iseguard.dll files, but I found none.

The only thing that worked was searching "Mozilla" in files and deleting everything except what my computer said was part of the system. After that, I was able to open Firefox, but after a short amount of time, the problem started all over. I have no clue what to do and looking all over for solutions is driving me nuts! Please help!

I have just upgraded my pc, new motherboard, cpu, ram and m.2 drive, of which I made a clone of my previous windows installation, on first opening it had the previous session, where i had opened another tab while it had the restore session tab open, this usually isn't a problem.

However it lost the session to restore, I have tried a complete copy from %APPDATA%/Roaming/Mozilla over to the new system, but to no avail, the session can still be restored on the other setup currently, which I had copied over manually to try resolve.

I even tried to copy the files 1 by one to test from sessionstore-backups and renaming to sessionstore.jsonlz4, however upon opening firefox, it rewrites the 9.5MB file with a 2KB file and I have no session to restore.

Is there a way I can resolve this as I don't remember all the tabs, I do need to go through them, but several I had open to return to.

Any help would be appreciated so I can get these back and go through them, would be easier than trying to copy all the URL's one by one to check them

Hello,

Starting Firefox 97, opening a file involves downloading it the same way as if I choose to save it. It results in both Download folder and downloads list in the browser being polluted with a million of files I only wanted to open once with a specific app (pdfs, xls, m3u etc.).

Previously Firefox was using a hidden internal folder for saving such files and deleting them later, so Open In App really meant "open, do not save locally". Now any option just means "Save the file to the Download folder and let it be there forever".

How can I fix this unsuccessful UX decision apart from downgrading to an older version?

Thank you.

P.S. "If you dislike new features in the latest version of Firefox, your first reaction might be to go back to the previous version. Rather than downgrading, try getting used to the new features..." is probably the worst suggestion you can possibly give to someone with their workflow broken by a sudden update they can't decline with a feature they never asked for.

Certain site show what looks to be Chinese writing in the menu and description. Videos for those site will not play. This just happen today. Is there something going on with firefox? what would be the best fix?

Firefox is steadily being unusable for me. On numerous occasions websites fail to show log in pop ups etc which work without issue in Chrome. Latest example : https://www.gog.com/en/games Clicking "Sign in" should show a pop up to allow me to sign in. In Firefox this does not show. I thought it may be a "pop-up" issue, so deselected "Block pop-up windows" in settings. Still the same. I added the website as an exception and still the same. Anyone have any ideas what is going on ? TIA, ZTB

The behavior of FireFox saving PDF files has changed. I am using WIN10, FireFox 98.0.1 and have it setup to use windows default application and always ask where to save for PDFs.

BEFORE the problem: The PDF opens in Acrobat Pro IX. After clicking save I would be asked, where to save. I select the location to save the PDF. Then after this, subsequent PDFs downloaded would be saved to the last saved location. This process would repeat for a new website PDF load and save. This is the behavior I want now.

NOW with the problem: The PDF opens in Acrobat Pro IX. 1. Immediately, after a reboot, the save icon on Adobe is grayed out. I select save as and point to the desired directory. 2. For any subsequent PDF opened, the Adobe save icon is available. Files are saved to the desktop.

Please note I believe I once did get a popup asking where to save and I know I selected desktop.  Since that selection I am no longer asked where to save.

Please note I have looked and tried some of the suggestions at: https://support.mozilla.org/en-US/kb/cant-download-or-save-files#w_choose-a-different-download-folder

but some of this advice needs to be updated for the new FireFox version--ex no JSON file is found at the file location covered in the advice.

I believe this issue started after the last FireFox update. Please help me restore behavior listed above under “BEFORE the problem”. Thanks.
