It's really strange (I'm still trying to understand my relatively new Windows 11 laptop), bookmarks have been where I'd expect them for a few days, then this morning, it's as if Firefox has done some sort of clean/re-arrangement. The bookmarks had disappeared and there wasn't my usual array of sites available along the top. Then by clicking on a few things on the right (Firefox) 'most used' re-appeared, then later the toolbar is there on the right, I'd really like it back on the left And also I'd love to know whether I might have done something unconsciously which caused this.

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

Yesterday I synced Firefox desktop to iPhone 13 and iPad 11. I created an account. The syncing worked.

Today I tried to access one specific website and got this message: "500 server error. Oops. Sorry. Your request could not be carried out because of an error. Please log out and sign in again". That didn't work.

I tried accessing other websites within Firefox desktop Version # 140.04 64 bit. They do work.

I don't know if this service error is something within Firefox or within Windows 10 latest update, or something else. I've reviewed system Administrative Events and there are numerous notes for 7/18/25. Many say "Distributed COM" some are Service control manager, many entries "Device setup manager". I have photos of several screens.

I've deleted cache and history (I use private Mozilla). I've restarted the laptop PC twice. No change to that website access. I used troubleshooting and that didn't help at all.

Please help diagnose where the problem is and how to fix it if the source is my computer. If it's a server problem please advise. Thank you. JHL

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Have an app with a web interface that I used for years, but not with several of the latest versions of FF. Chrome, Edge, and DuckDuckGo all show the page as expected and the page functions properly.

URL: http://127.0.0.1:8384/ Error looks like this:

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:[port number].

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

Have tried a large number of things including:

Ping works for ip and hostname, v4 and v6 Confirmed address is accessible through other browsers Disabled extensions Added exceptions in Settings for HTTPS-only mode Various settings in about:config, careful to return them to previous states when they didn't fix the problem Tried Safe Mode (aka Troubleshoot Mode) Refreshed Firefox (as prompted before uninstalling)

My last step is to reinstall, but thought I'd ask here first. Has anyone seen this before?

Hi

Lets say i have 100 tabs open in my session. I mistakenly open a new window with one tab. After closing this window and starting firefox again, it starts with this one tab, so i have lost all my previously opened tabs. Is there a way to get those back?

Thank you very much. Dimitris

Every time I access the web I get a report from Norton saying "Threat secured". It attaches every single website that I open. See attachment for some exmaples (only variabole part of message shown apart from first one).This is occuring 50+ times a day but does not occur using Edge, so it appears to be related to Firefox. PLEASE help. Norton have not helped with this. Thank you- Colin O'Brien

I was creating a primary password and for some reason it "glitched" or "stuttered" and it created the password without me knowing what it was. I tried several combinations that could be close to the one I was inputting. Can I uninsall Firefox and reset the password?

I cleaned the AppData folder to speed up the computer, then it turned out that there were Mozilla files, which threw away all my data form browser. I synced the browser data on the phone, but it didn't transfer everything (history and login data missing). What to do to have my passwords again on the computer?

Every time I make Firefox full-screen, it immediately crashes and shuts down. I have restarted the computer, uninstalled and reinstalled Firefox, but it still doesn't work.

When using the new version of Firefox, I found that bookmarks only appeared in new tabs. Once I opened other web pages, there were no bookmarks above the screen, which made me feel inconvenient. Previously, the new tabs could also be customized, but now they can only be blank or the default pages of Firefox. So, can the new version of Firefox solve these problems? Or which of the older versions of Firefox can still meet my requirements?

No matter what settings I change, I still can't get audio to play from Firefox. I can use other browsers and get audio so I know it’s not my computer. I’ve even tried to uninstall firefox and install the newest version with no luck on getting my audio issue resolved. If anyone has any advice for me, it’d be greatly appreciated
