I switched from Windows to Linux. I have signed in and tried retrieving bookmarks, browsing history and passwords, AFTER already having formatted my computer and deleted Windows. I signed in to the same account, had syncing on, but i can't seem to get any of the stuff back. I didn't have any additional backup files with those. Is there anyway i could somehow restore it all? The bookmarks are most important to me out of those. I'd be extremely grateful for any help

As of yesterday my Firefox browser no longer displays some screens within Amazon Prime correctly. It displays what should be images as text, which is difficult to read, unlike Microsoft Edge, which displays the Amazon webpage correctly. I am running Windows 10 with a support extension through October 2026, so could it be an update from Microsoft Windows or Mozilla Firefox that has caused the problem. Thanks for your help.

Hi, my extension is 3 days on awaiting review, I release/sign pretty often as it's in active development. Is there anything I can do on my side?

Addon Name: Hutch

I'm suddenly having a problem where images don't save as .jpg unless I add that myself. At first, it wanted to save images as WebP, but I was able to fix that in the about:config. Now when I go to save an image, it wants to save as Chrome HTML document and I have to click all files and then add .jpg.

Hi, I opened Firefox to continue with my work, just to get greeted with a 'start a new profile' page. All my profiles, saved data, history, add-ons and customization, were discconected/removed. Even on my phone it logged me out from my account- logging back in doesnt retrieve my history from my previous sessions on my desktop device.

I tried logging in to my account, checking if theres an 'old firefox' folder on my device or anything like that, but it did not retrieve any of my old data.

Just to clarify, I have not played around with my settings, left or deleted anything, so I really dont understand why I've just came back to nothing.

Was wondering why this happened, how do I know this won't happen in the future, and if, when possible, how can i get all my data back?

Thanks

Hallo, ich benutze immer den aktuellen Firefox unter Debian Trixie. Ich habe jetzt das Problem das sich das Fenster meines Firefox nach einiger Zeit der Untätigkeit von selbst verkleinert. Sprich, wenn ich einen Button drücken möchte dann muss ich mit dem Mauszeiger eine Zeile höher drücken als der Button liegt. Meine Treiber sind alle aktuell und ich habe früher dieses Problem noch nie gehabt. Wäre euch für eine Hilfe dankbar. mfg Schorsch

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

If it ain't broke, don't fi(o)x it. Never try to be too clever. I cannot log out of OUTLOOK.COM, then after goodness knows hot long, it says that I have been kicked out and need to login again. CRAP!!!!!!!

Hi Had some problems with the computer. According to Microsoft the dll error was caused by the new Adobe acrobat. Trying to fix this problem some of the websites in Firefox are having now problems. EXP. Kohl's Error code: SEC_ERROR_REVOKED_CERTIFICATE. Home Depot Oops!! Something went wrong. Please refresh page. This is only happening in Firefox with Windows 7, Firefox version 115.33.Oesr 64 bit. When I access these two websites on Chrome in the same computer everything is fine.

What is causing these errors in Firefox????? Can you please help!!!!!

Since changing to a new internet service provider, I can no longer print form Firefox. My internet router uses the same username as password as my previous router.

Whenever I open a new firefox page externally, such as from the system tray or by opening a link from outside firefox, nothing happens for about five seconds and then it loads normally. When I open a new firefox page internally, such as from file ---> new window or by clicking a link within firefox, it loads instantly like normal. This has been happening since yesterday (3/13/26) evening.

I have already tried all of the following fixes and none have done anything:

Clearing firefox startup cache running firefox in troubleshoot mode running an older version of firefox disabling all my extensions disabling my antivirus disabling hardware acceleration disabling captive portal detection making sure both firefox and windows 11 are fully updated refreshing firefox reinstalling firefox rebooting my PC disabling IPv6 preventing accessibility devices from accessing my browser clearing my cookies
