Hi, after clicking FF icon, I got nothing. Profile manager (firefox.exe -P) does not start. In event viewer there is log: Name of the application causing the error: firefox.exe, version: 147.0.0.11, timestamp: 0x695c3722 Name of the module causing the error: unknown, version: 0.0.0.0, timestamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x00007ffc561c6160 Faulting process ID: 0x4A54 Startup time of the application causing the error: 0x1DC85EE68CB3BAD Faulting application path: C:\Program Files\Mozilla Firefox\firefox.exe Faulting module path: unknown Report Id: e599c553-d77c-4b73-a863-1ccaa8d3bd4c Faulting full package name: Faulting relative application ID for package:

Last time deleting profile was helpfull, today nothing helps... Reinstall - the same... Any ideas?

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

I opened Firefox this morning and all of my pinned shortcuts have disappeared. Shortcuts are enabled in the settings. I checked the browser.newtabpage.pinned pref on the about:config and all of my pinned shortcuts are still there, but they're not appearing on the actual page itself. Are there any other settings that I'm not aware of?

From "About" on the Firefox menu I am trying to download the update from 145.0.2 but it is stalled at 27.1 of 31.3 MB. The little pair of spinning arrows icon just keeps spinning without making any further progress. I'm on a 2020 iMac running Sonoma 14.5 My internet connection is still functioning. I'm wondering what I should do. Is there a way to just cleanly stop and start over? Or stop and continue.

146.0 (64-bit) Windows 11 December 11, 2025 Turned on computer this am, Firefox webpage popped up telling me about what is in it's future but now my side bar is black print on really dark background. Help!

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I have downloaded Firefox ESR and think it has been installed on my masOS version 10.12.1 and am wondering if I can use it on this version after reading your warning about support. Perhaps I have not installed it properly as I have just used what I think was the previous version since it has all the oldsaved sites.

I've been using Firefox all morning. Now, for some unknown reason, every time I start it up, it immediately crashes Windows. I mean, within 1 second or so. There's no time to do anything. After the fourth crash in a row, I just restarted Windows again. It was humming along happily for 10 minutes or so, and then crashed as soon as I started Firefox. After the first crash, the first thing it did was update, but that didn't fix anything. I'd love to share data with you but I'm forced to use Edge right now.

Please dont turn firefox into AI slop. The browser does not need "AI" shoved into it and currently the lackthereof is one of the only things keeping a large user base with firefox. Please please don't cram more AI down our throats. Again, no one wants this shit except MBAs.

Running version 146.0.1 No new extensions. Recently, when I hit ctrl+b to bring up the bookmarks sidebar, it opens but doesn't display the bookmark correctly. (image #1) The sidebar opens, but everything is whited out. The same thing happens when I try to open the history sidebar, except that the urls kind of show up. (image #2). Also, when I'm on my homepage, there's a white line on the left side that I can't get rid off. (image #3) I also tried refreshing firefox, but that didn't do anything. Does anyone have an idea what may be causing this? Thanks

The lack of a title bar makes it impossible, for example, to close the application by pressing the "X" icon in the upper right corner. The title bar does not appear when the application starts, but does appear when the application window is minimized and then maximized.

I don't remember when it started but text that wasn't underlined before such as: Names of shortcuts in new tab view Titles of YouTube videos on home page, and recommended while watching a video (not on the video itself) Reddit titles and usernames (old UI)

I have checked settings as best as I can and tried disabling all extensions but still have the issue.

When trying to access windinfo.eu, I get the message "you are not allowed to preview snippets". Other websites work o.k. I had used the snipping tool on a different website, but not on this one. The problem persists even after deinstalling the snipping tool and restarting. On edge, I get access to windinfo.eu.

Many thanks in advance for your help
