Firefox Support Forum

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

This is my story. Digital affairs are serious problems for a marriage, although sometimes, they are also a symptom of underlying problems. Either way, you may quickly end up needing a divorce lawyer’s assistance if you do not put a fast halt to what is happening. Previously, traditional notions of infidelity required an actual physical relationship between an unfaithful spouse and their romantic partner. Thanks to the chxhack @gmailcom who helped me to dig into the communications of my husband platforms like his phone and social media, that i discovered that he was hacking extra affair and i got all the records of the communications and i was able to save my marriage. therefore if you are experiencing such worries get intouch with above. thank you.

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.

Well, I have applied all the options about proxy settings with the same result of long time for opening websites when first start of firefox. During these months I took notice to the one point, i.e. if I open website using firefox in the earlier morning there is no problem with the speed of opening as well as if I open another browser of edge the last one opens website without any delay. So the challenge of long time opening websites when the first start of firefox is still in force. How to resolve this?

If I Open normal window (not private) then click menubar/3 bar menu (upper right side) and click 'new private window' and then close normal window, it also closed my private window. v121.00

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.

Hi! Yesterday i updated my firefox to last version and i got my UI way too big, so today i looked online for some fix on that. I found a fix saying if you add a line in about:config site with the parameter "ui.textScaleFactor" with a value of 100 it will be fixed. but by mistake i changed it to 10 insted of 100 so when i open firefox i have a super big black screen

most of my problems are i can't reinstall firefox because it made the same weird big ui problem. There is any way to fix it?

thanks in advance

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. Another dialogue box opens saying couldn: load XPCON

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 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 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

My work consists mainly of capturing accounting data online. It is important that the browser warns me if I try to close or navigate away from a page if the data entered has not been saved or updated, but I no longer get these warnings.

Please help.

Hello there! So, I've just installed Firefox in a notebook I have and now there's a website where I can't see some pictures. https://i.imgur.com/E86dhVB.png There should be a picture there instead of (IMG:link) https://i.imgur.com/7lzrbfU.png There should also be a picture there, behind "Redvirux". Some pictures are shown, though, but most aren't. It's an http website, but it had been working fine on my Windows 8 instalation. Do I need some codecs? Is it a Windows 10 problem?

After i moved to another location and getting now internet via fiber and via fritz!-router 7530 i have issues with readability in many cases: Google News, Mailbox at GMX. To the 7530 my notebook is normally connected via WLAN. Text is in places often not shown, or colored in black or green or magenta, Images are often in places or complete filled with flicker (white, green, magenta, black). I suspected the WLAN connection and searched and read the ffox-help und tried some things, but nothing helped. Using a long cable from 7530 to nb has no effect.

Firefox is the only application affected (latest 107.0.1, Windows 11 pro latest updates). I have updated all drivers, run system and memory checks, uninstalled deleted remaining files and registry settings, twice actually all to no avail.

I have recently changed ISP but cannot see how that affects just Firefox (Chrome/Opera/Edge all work) and also moved to Bit Defender antivirus. Here I think I saw startup installations in Chrome etc for bit defender but never for Firefox. I have tried turning off all virus web protection still no joy.

I have looked briefly at the crash reports but with my level of expertise I can see no common crash reason.

I have had no add-ins installed for last week while trying to get this to work again. I have used Firefox for years and have no wish to move to another browser but this situation is driving me nuts.

If there is anybody out there with any ideas on next steps I could take?

Cheers Mike

i click on the download folder in firebox and doesn't open as its used to.
