Title says it all, "auto resize pictures using CTRL - + does not work". Generally speaking, the size of pictures simply WILL NOT reduce in size to view its entirety. Even when the scroll-bars are used the picture is still to wide. I have searched and asked for any setting in about_config, NOTHING! I truly expected something. The ONLY STUPID WAY to view said oversize picture is Download it then view. Isn't that a HACKERS DREAM??? YES I HAVE tried looking in SETTINGS and searched for months, found nothing that actually works. So now I have to use that 4-LETTER word... HELP!

On two different Windows machines, current Firefox (153.0.1), the alt-d shortcut stops working: it does nothing until I restart Firefox. Then it works again for a while. I've tried about:keyboard and it's not reset there. I tried all combinations: Clear, Reset, setting it to alt-d explicitly. None of those worked. But when I set it to alt-a, that worked--but then resetting back to alt-d again didn't work. That shortcut is muscle memory at this point, so it's quite distressing. Not sure what diagnostics might be available to help here, happy to try anything.

Full disclosure: Both machines are Windows 10 but since that's stable, I find it hard to believe that's related.

I want to make the switch from Chrome to FF (to continue using UBO), and a problem I keep running into is media not displaying in Twitter(X)'s DMs while using Private Browsing mode. It only comes up as a gray block that says "Failed to Load" with "Retry" under it, but it never loads. It also asks that I re-enter my DM password every time the page reloads.

Everything works fine in a regular browser tab, the issues only occur in Private Browsing.

I have tried disabling UBO, disabling Enhanced Tracking Protection, and clicking the little shield icon in the URL and turning that off, too. Looking this up really didn't give me any results that actually helped, either.

Help would be much appreciated! This really is the last big hang-up I have to not switch.

I couldn't see password management page. To be specific, I click the "password" option in the top right corner lists. Normally it will show all the website that firefox saved, but now I couldn't see anything except frame. I will upload the interfance that I see. this problem happend since an update. And problem contines after several patches. The firefox version that I use is "153.0.3(64-bit)" please help!

High contrast setting only support 2 colors(unvisited links and visited links) as a consequence it does not support radio buttons(switches that move to left and right to turn on features). the buttons are invisible and waste hours of the users time.

Background: On August 6th morning EST after the August 5 2026 update, attempting to use firefox lead to the window with the "end process" button so I had to close the browser multiple times and then the next time I opened firefox, the bookmarks and history were wiped. I was able to restore using a backup saved on the computer and continue as normal (aside from losing some Cookie Clicker progress, reinstalling Tampermonkey userscripts, and redoing browser extension settings) but now there's an issue with trying to backup firefox data.

Issue: Trying to back up my firefox data leads to a "There was a problem backing up. Try again in a few minutes."

When going to about:config and typing browser.backup.backup-debug-info, I get {"lastBackupAttempt":1786243812,"errorCode":9,"lastRunStep":13}

When looking at Broswer Console, there is an entry saying BackupService: Could not create C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini: NotAllowedError: Could not write to `C:\Users\USERNAME\Documents\Restore Firefox\desktop.ini': failed to open file for writing (NS_ERROR_FILE_ACCESS_DENIED) BackupService.sys.mjs:4116:23 but I don't know how to address that.

Please help, it looks like my passwords are not synced anymore on any Mozilla I use. I sue a Mozilla portable at home and a classic desktop on my office. The synchronyzation works for bookmarks, browse history and download history but not a single password is imported on my sessions ! My files are present : see screenshot01 so my passwords are here. Login.json contains data. So what's the problem. The debug mode said that : see screenshot 02 Thanks for the help

Dozens of reboots every day due to video seizures only with Firefox. Tab crashes causes those I am ordered to support to LOSE WORK. After a tab crash and restore the FF interface is frozen -- no type of input from peripherals possible. This is all supposed to be solved by Monday. If I am out of luck with FF -- just tell me. That's very simple. New machines, new OS and it's worse than under the legacy systems we support after moving up from Win 7 Pro.

It was working just fine, and suddenly it stopped working. I hadn't rebooted my computer for over a month, and accidentally popped the circuit breaker the computer was connected to, so it rebooted for the first time in a long time. No other issues except Firefox will not connect to the internet when Proton VPN is running, but Firefox works just fine when the VPN is turned off.

I updated to the latest version of Firefox, so I assume that's the same thing as reinstalling it.

Proton VPN allows you to do what they call "split tunneling", where some browsers are excluded from the VPN (Firefox) and other browsers are always behind the VPN (everything else). I use Firefox as a secondary backup browser when the VPN is a problem and I don't want to turn it off.

I ran the Firefox "Safe Mode" and that failed to connect as well. I don't think it's the VPN? But maybe?

Any help appreciated, and thanks in advance.
