I was experiencing that one bug that locks the sidebar from opening on hover (even with the option enabled) and I was somehow able to change the size of the sidebar while trying to get it to start working again (IDK why I didn't just close and reopen my browser because I know that fixes that) and now my open on hover sidebar is the biggest it can go and it is genuinely unusable. I can't change the size of it while it's on the open on hover option, but changing it back to the fixed/static sidebar and then editing the size does not carry over when I re-enable the open on hover option. Objectively, this is really dumb and kind of hilarious. I know I am dumb for this.

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

I lost the ability to browse using multiple tabs. I have to open multiple windows because the browser automatically goes directly to the site rather than a new tab. I've used firefox for YEARS. Must I change browsers to have this feature?

Hello there, today was released a new version of firefox. downloading it not only crashed my computer, it also removed all my history and bookmarks. is there any way to revert this?

My browser has been hacked by searchingswift.com, I've read all the article's I can find on getting rid of it with no luck. I've completely uninstalled everything including the mistake that brought it in (Coverseen miss pick file), but no luck.

Here's what I get after a complete reinstall and deleting any Firefox stuff I can find.

I'm getting ready to do a backup from a month ago, but I'm not sure if this will come back in with my Firefox sign in.

Windows 11 and New Firefox

Site: https://www.thegamer.com Firefox refuses to load the site, it does not even show the certificate when clicking on the lock. Using the certificate manager, add exception does not work too, it just refuses to store the certificate. But at least THERE I can VIEW the certificate, which proves it is valid and FIREFOX is at fault:

https://www.ssllabs.com/ssltest/analyze.html?d=www.thegamer.com&latest shows "IO exception" when trying to check the CRL, but gives an A+. Yet Firefox does not even give me the "Continue anyway" possibility. This it tiering, I hate using google chrome based browsers, but of course, it works there. Server 2025, only MS-defender at its default settings.

I've been trying to open Google Docs on Firefox Desktop for a few hours and none of my troubleshooting has worked thus far. I've cleared my browser history and cache, have updated Firefox, disabled all browser extensions one by one, updated my proxy settings, changed my TLS preferences, and even added Google Docs to my trusted sites list on my computer itself; none of this has worked. I've been able to open Google Docs on Google Chrome, so I know that it isn't a problem on Google's end. If there are any other possible solutions, any suggestions would be appreciated.

Can Firefox do anything to recover all of the downloads I'd saved until I accidentally had CCleaner erase everything? I don't know what else was deleted, but getting them back would be a big help.

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

When I logged in this morning my bookmarks toolbar was gone, along with the favorite start. I have googled and followed support articles and the only thing I was able to do is get the menu bar to show along with the the bookmark menu but customizing the toolbar.

I found 'chromeasia.com' autocompleting in the Firefox address bar upon typing 'ch'. I searched History for this and there was no sign of it. I cleared all history data, rebooted, ran a disk cleanup and find that 'chromeasia.com' stil autocompletes upon typing 'ch' in the address bar.

Any suggestions or advice on how to clear this would be warmly appreciated. Thanks. Stephen

If I have edited the passwords file and bookmarks file and saved them to a folder via export feature. When I import the edited file into firefox how can I make that the master file and not have the other instances of firefox sync all the old data back to the master one I edited? For instance I have FF on android, linux and windows, if I import the edited file to the windows instance what is to stop the linux from syncing back to the windows machine? I have had this happen previously where a newer instance of firefox overwrote the bookmarks and password files. Will I have to delete all bookmarks and passwords and import them from the new edited file on each device?

My account has my primary email and it used to have my secondary email connected as well. I now want to create a new account with the secondary email so I can have another profile, so I deleted my secondary email from the manage accounts on my primary email. I ensured that this says it is removed on all devices and it is. But when I try to create a new account with that secondary email, I keep getting the error that I need to sign in my primary email and I am taken back to my profile with my primary email.

How can I fully detach my secondary email so that I can make a new account with it?

Firefox crashes whenever it would need access to my camera or microphone. So far it has only happened whn trying to access a Roll20 game with camera and microphone connectivity, and when trying to access a video appointment for Universal Credit. It never happened on Windows 10, but since updating to Windows 11 it happens every time without fail, and the crash is immediate.

Problem: Cannot clear history from Firefix Started with Menu and clear recent history. Looked everyplace there was information about history. Tried removing individual entries. Ran Malwarebytes. Dell XPS 8960 with Windows 11 less than one year old. No response with any steps I take. Also, there are no error messages. I am unable to clear history no matter which tools I use. No error messages. All the suggestions I tried had no effect. Used Troubleshoot Mode in Firefox.

Oddly, I tried my older Dell Inspiron 3650, with Windows 10, and clear history works like it should. 

Used Troubleshoot Mode in Firefox. So far, all the advice goes down the same path; history, clean recent history, manage history, etc.. Tried refreshing and today I deleted Firefox app and reloaded. No improvement. Results same with Verify Integrity > Task: checkIntegrity - Unable to fix corruption, places.sqlite will be replaced on next startup > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task. Please help... Rangercarol

I was resetting my password entered my email code recovery key it didn't ask for my authenticator got an error invalid token then after retrying it asked for email and authenticator but not the recovery key the account now says I have no key

since the uptate to version 144.0.2 I have two problems. the first one is async streaming on platforms eg. youtube or netflix. The videos take a very long time to load. Even if a video has already preloaded and I skip to that area, the video takes an extremely long time to load again. The 2nd problem i have in livestreams eg. live-TV or twitch. The loading time is very long. It is so long that many livestreams are doesn't even able to start. So, it is no longer possible for me to watch livestreams on Firefox. what i've done to fix it: - I deactivated all Add-on's and deleted all browser Data - I made a new profile and deleted the old ones - I reinstalled Firefox

Nothing worked. so pls can you help me that I can use Firefox normally as usual? (sorry for my bad english, I'm from Germany)
