Firefox Community Forum

my PC was lagging on wake up so I was disabling some things at startup like duck duck go and copilot to see if that helped. I have windows 11. somehow during the process my google sheets will no longer perform copy > paste special values anymore. It works on my Mac and it works on other browsers, but I need it to work on firefox. went to google sheets help, they are also stumped.

My Surface Laptop 7 w/ SnapDragon Elite's Firefox installation started crashing this morning immediately after rebooting to complete some Windows updates. I have attempted starting Firefox in Maintenance mode, Uninstalled and reinstalled and I still get the crash reporter. Refreshing Firefox at the uninstall process does not fix it.

I'm running Windows 11 Enterprise edition, fully patched w/ Firefox 146.0.

The 4 Windows updates that were installed:

Uninstalled KB5072033 Uninstalled KB5070311 Cannot be uninstalled KB5072641 Cannot be uninstalled KB5071142

Still didn't fix the problem.

These are the recent crash reports:

Crash ID: ⁨bp-8ec5b63c-4408-437c-b9bb-f4d5b0251213⁩ Crash ID: ⁨bp-ce396463-0a75-46b6-8131-33cce0251213⁩ Crash ID: ⁨bp-ea0b59dd-1cee-48da-957e-949120251213⁩ Crash ID: ⁨bp-f9342e01-1a55-4387-af6d-3b8ef0251213⁩

Any help is appreciated!

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.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at fzttlwrt.r.us-east-1.awstrack.me.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I've purposefully used the environment variable to disable the security sandbox.

How can I acknowledge and hide the persistent warning? Is there any about:config value for it?

Thank you!

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 run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

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.

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

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

• First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
• Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
• When I try searching for tags in Bookmarks Manager, the search yield no results
• When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
• When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?
