Firefox Support Forum

On my new PC with a fresh and fully up to date installation of Windows 10, Firefox tabs keep crashing for no reason.

Ticking all the boxes they give me in the crashed tab and hitting reload/refresh tab is unlikely to actually fix the tab. I have to hit that button at least 5 times to maybe get the tab working again and even then it's basically a coin-toss whether it actually gets fixed or not.

I have 7 firefox.exe.(number).dmp files with no way to upload them here but if there is an way to do that please let me know so I can provide additional data.

Please help me with this ASAP, I'd rather continue to use Firefox on my new machine than go back to Chrome. Thank you.

Just got the latest firefox update, now i can't play zynga poker. https://apps.facebook.com/texas_holdem/ before update, i can play it, but after 1 day it slows down, have to close and restart firefox. it happened also in Developer edition. It never happened on chrome.

Is it possible to remove / hide individual elements inside the Library popup's #placesList (i.e. the Tag item and/or the icons of any of the items)?

My attempt with the code below inside userchrome removed ALL of the side panel content - not ideal.

#placesList > treechildren:nth-child(2) {
  display: none !important;

}

Also, is it actually possible for the Browser Toolbox to work inside popups?

I cant access specific greek websites like culture.gr, mfa.gr, idika.gr, eprocurement.gov.gr Chrome and Edge have no problem accessing them. Firefox version is 91 (win10) Thanks for your help.

Hi,

Im using Firefox Developer Edition and every time I make a change in website's source code (not by "inspect element") I have to restart Firefox to see any change that I made. Other browsers show those changes so it's not server's fault.

Since firefox updated this morning, I'm no longer able to log in to some sites using forms once auto fill is active.

I've created a new blank profile to test, and it's the same behaviour.

1. start blank profile 2. visit https://bandcamp.com/login 3. enter a username and password (doesn't matter that it's not real) and hit Submit 4. tell Firefox to remember password. 5. clear the form and reload the login page. 6. try to allow firefox to auto fill the fields

There's a really weird mix of things that go on

- sometimes one of the fields is populated, more often they both go yellow, but blank. - double clicking in a field seems to momentarily reveal contents, but then it goes blank again. - typing in an apparently blank but yellow field seems to suddenly append characters to the auto-filled value.

Firefox crashes at startup even in safe mode. I think there was firefox update after first crash and it did not start after that. Developers version works fine.

Is it still necessary to use both !important and @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul) inside userChrome?

Managing profiles: My Firefox since rel 89.0 crashes several times A DAY. The last time it crashed 6 times in a row then WIPED out my copy and gave me a new copy, BLANK of everything. I am no rookie to Firefox as my first version was 1.0 when I converted from Netscape Navigator long ago. The rub is PROFILES. I have too many to manage now and need to get rid of some but Moz:lla in their infinite wisdom does not put a date, what was the LAST one.... and one has to search to find the LAST profile that has your latest modification, data, etc. I am fearsome in deleting any as they do not seem to be in any order and I get a SERVE warning when trying to delete. Since the new releases crashes all the time, to do critical work I have to resort to UGH, "EDGE' until Moz://a gets a solid release and hopefully STOP TRYING TO COPY EDGE AND CHROME.

Any advise will be appreciated. [except advise to use EDGE or CHROME].

When I was using version 88.x, Firefox had not crashed for years. Then all of a sudden, Firefox would crash several times a day. I looked and Firefox had updated me to ver 89.0. But I let it ride. Then Firefox about a month ago, Firefox stsrted to crash EVERY DAY. Then one day it crashed EIGHT TIMES IN A ROW and I mean when I hit RESTART, IT WOULD CRASH. I tried to revert to rel 88 but Mozilla WILL NOT ALLOW US TO REVERT BACK TO A PREVIOUS VERSION. When you do, the PROFILE gives you TWO OPTIONS: 'EXIT or CREATE A NEW PROFILE.' Certainly you do not want to CREATE A NEW PROFILE as you will LOSE, your history, add-ons, Bookmarks, EVERYTHING and you see a WHITE Firefox screen with nothing. So I choose EXIT and tried to put up with the CRAPPY ver 89. BUT FIREFOX KEPT CRASHING. TODAY IT CRASHED SIX TIMES IN A ROW......When I checked the VERSION, YOU HAD UPGRADED TO VER 91.0b6 (64-bit) AND IT IS NO BETTER.

WHAT IN THE HECK IS GOING ON. I DO NOT WANT TO LEARN CHROME OR EDGE AS I HAVE USED FIREFOX SINCE VERSION 1.0.

DOES ANYONE KNOW HOW TO GO BACK AND KEEP YOUR OLD PROFILE, FLACKY OR NOT AS THAT IS BETTER THAN 'RESTARTING' FIREFOX ALL THE TIME.

MY VERSION 88 NEVER FAILED.

I did not choose a BETA VERSION. I have used FIREFOX since VERSION 1.0. IT USED TO BE THE BEST BROWSER EVER CREATED. BUT NO LONGER. WE use Firefox to accomplish things, not to debug BETA versions all day. One day I wake up and you FORCED rel 89.0 on us and it turned the whole WEEK to crap. I had 6 consecutive crashes the other day. Today I had 5 consecutive crashes. I had to turn my PC off and give it and me a rest. I did not ask for a BETA, even to leave rel 88. YOU 'forced' it on us with your "you have no other chooses if you want to continue using FIREFOX attitude. And all you can say is: Go BACK to 'stable rel 90 AND CREATE A NEW PROFILE? DO you have any idea how hard it is for us, a USER to CREATE A NEW PROFILE FROM SCRATCH?

THIS MAKES NO SENSE, YOU CRAM A "BETA" ON US, IT CRASHES A HALF DOZEN TIMES A DAY and your answer is to go back to a stable version YOU FORCED ON US? Then we spend a day or two creating a NEW PROFILE until you force ANOTHER BETA on us to test for you? You can't let us stay on a STABLE version like rel 88 until you work out the bugs then "tell us" there is one available and advise us to INSTALL IT? THIS IS CRAZY, let alone "Professional".

Frequently after an upgrade my FF (91.0b7 (64-bit)) on Win 10 reverts to the previous version. I only notice it because I start getting prompts to upgrade.

Frankly, I'm pretty clueless and sick of Windoze but determined to not resort to Chrome or hEdge. ANY suggestions to help figure what's happening (and hopefully how to prevent it) will be greatly appreciated.

I really dislike the look of the tabs in the newest version. A floating bubble, not connected to the page, for the active tab? And the inactive tabs are connected, but there is no separation between the tabs? Aside from uninstalling the latest version and installing a previous version, is there a way to restore the look of the previous version? Maybe an add-on? If I have to reinstall an old version I'll probably just switch over to a different browser.

Firefox started crashing a few times a day after updating to v91.

I checked and It looks like crash reports aren't being sent to Mozilla, even though it's enabled in settings. The last one that was sent was in 2019.

When I try to open "Firefox Developer Edition Crash Reporter.app", the crash reporter crashes.

Since couple of months ago, FF started to ask for master password after 30 minutes of inactivity. I have auto-refresh for some tabs which use Basic Authentication. After 30min those tabs stops refreshing and FF opens multiple (5) dialogs for master password. This secondary layer of security is pretty annoying as I have my computer secured on multiple levels by multiple factors already. I am getting very annoyed by this, is there any way to disable this "feature"? I have security.ask_for_password = 0 and signon.masterPasswordReprompt.timeout_ms = 0 but it keeps asking (now bit less often but still does). I just want master password entered once when I start the session and keep it open until I quit the browser.

Hi, in an update recently my address bar has changed to show my search history or similar named things instead of just the website itself, how can I change this back

Also the search bar on the right increased in size or no reason, how can i fix this.

I lost my laptop and had to get a new one and downloaded firefox. is there anyway to get my bookmarks back? it had links to my course work including passwords and such
