Firefox Support Forum

Please my firefox appears to have crashed, or is not working how can i fix it. As i try to open firefox document a dialogue box appears saying that either the firefox is not designed to run or that i should reinstall firefox

I just "refreshed" firefox after it stopped loading all the websites. I then tried to isolate the problem, found out that there is no issues with my firefox and any of its add ons. But as soon as I add Chrome folder and a css to enable multirow bookmarks folder. No website launches. Just white screen. Anyone experienced the same?

Please help as I really need multirow bookmarks. Thank you.

I would suggest within the last month or so Firefox has started to hang in a way that everything continues to "work" but I cannot switch tabs and I cannot do anything else with Firefox until I kill it.

I can periodically reproduce this by: Randomly select and copy text on a website.

Behavior observed: You can no longer switch tabs, enter a new location, close tabs, or really interact with the browser at all even though it is not dead. Keyboard shortcuts do not work either.

Version: 107.0

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

No matter what I do FF always opens to the "Success!" screen and wants me to choose what tabs to restore. I have done troubleshooting mode, clean mode, refresh and complete uninstall and reinstall. Nothing works.

Greetings Firefox Community

As I long time user and supporter (have donated and even got a shirt to show!) I have never had any issues with my beloved FF. If anything minor had happened, I would always find a quick fix on the community forums.

This one is an odd ball: for a while now Firefox forgets all saved passwords but only after a cold reboot (not a restart or sleep).

It's my elderly mum's laptop, which I manage for her using a remote desktop app. It's a fairly new Asus Vivobook with Win11, fully updated and free from viruses and hacks as we have installed paid versions of both Malwarebytes and HitmanPro.Alert. My Windows desktop runs exactly the same OS and those two security software, and my FF never ever forgets anything! The only difference is that her Windows and FF are set to the Italian language while mine is English.

After trying a "refresh", I exported her passwords and bookmarks and took the drastic step of completely wiping FF and even removing profiles. Reinstalled the latest x64 version and the problem is still happening.

Had a good look at both security software to ensure there was no funny setting to cause that to occur, fact is the laptop also runs Chrome and Edge with all the same saved passwords yet those two pesky browsers never forget anything!

Personally, I'd much prefer for her to continue to use FF rather than the other two, so I am shouting out for HELP, please! Hope someone has seen this and/or knows how to fix it.

Many thanks in advance and Merry Christmas to all! Cheers Paul Perth - Australia

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.

After i just updated Firefox to newest version .. I can not load any website anymore!!!!!! please make it so i can return to the previous version ASAP so everything works again.

Al those other solutions you guys give like clear cache disable en able etc don't work and take hrs of time

When oyu push a other update through some 1's throat atleast make it that it A)works B) option to roll back . TY

I can play videos and audios on another browser or files stored on my computer, but just now I cannot on Firefox. I saw the FAQ explanation about Windows 7, but I have been using Firefox for years including just hours ago using Windows 7. Why would this happen right now? Did some new version just get installed? If so, can I return to the prior version and turn off the automatic update?

Thanks, Phil

The browser (version 107) regularly crashes and then never launches. After entering failure mode, I disabled all the extensions, but it still wouldn't start. Later, I disabled the hardware acceleration, and I can start the browser, and the extensions work. But then, it still crashes occasionally and periodically. I tried to change to version 100 and also have a similar problem. Resetting Profiles would start, but it would still crash after a while. It crashes for me too.

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

I seem to have gotten something called Google Ad Services. It frequently interferes with my getting to websites and I cannot find how to block it or remove it. HELP!

Dear sirs,

I've got the latest English (US) version of Firefox 108.0 from this website. The problem is with Windows crashing in few seconds after Firefox is launched. Although this trouble appeared yesterday (maybe after the automatic update of FF - I'm not sure).

Please advise any solution ASAP!
