Firefox Support Forum

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

I have been reading the NYTimes on Firefox for a long time, but it appears that I got logged out without knowing it. I could not log back in even though I used the correct email address and changed my password twice. I can log in on other browsers using my latest password. I called the Times and the person with whom I spoke, after trying to get me logged in, finally said that this is a known problem with Firefox. He did not have any idea about the cause or what I could do; he simply told me to use another browser. I use Firefox for almost everything and this is, to say the least, an inconvenience--for instance, if the Times sends me a link to an article by Thunderbird (which is my email program), I can't read the article but have to find it on another browser. Are you aware of this problem? Do you have any suggestions for how I might log in despite it? Do you know the cause of the problem and whether Mozilla is trying to fix it?

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

Hi! I wish to edit my limit on how instances firefox runs but i cant. I searched up how to change but cant find the option for it. It said that i should just untick use recommended setting in performance but all that happens is tht i get anotheter option to untick hardware accleration.

session is completely gone. I tried to restore it via various help articles and forum posts but without success.

I see a stg-backups-ff-126.0.1 fodler in my download folder which contains information about tabs that I had open. But I don't know how to use firefox to use that file.

I alos tried to the \sessionstore-backups folder with files named like "previous.jsonlz4" but I do not get the menu option for restoring a session.

from a file named "error-sessionrestore-1718212432477.txt": 1718212432149 SessionStore ERROR The session file is invalid: : TypeError: state.windows[0] is undefined(resource:///modules/sessionstore/SessionStore.sys.mjs:1163:11) JS Stack trace: initSession@SessionStore.sys.mjs:1163:11 onBeforeBrowserWindowShown/<@SessionStore.sys.mjs:2035:35

FF just did an update and now I can barely use the browser. Its slow and then spins and crashes... it took me 6 minutes to just get this open and type this. All my links and sign ins are on it... ugh... How do I reverse the update? thanks

I started having new tab crashes a couple of weeks ago on Firefox and Brave browsers. I have looked in the extensions settings and do not have any added extensions so that did not cause the problem. I also run Norton antivirus and Norton Ultimate utilities software and regularly clean out files and scan my computer for malware. Not sure if Ultimate Utilities is the problem since I have had other problems in the past with that program. Also, I wonder if Windows updates caused this problem? This has also caused problems in the past. To get around this problem I have to copy the link then right click on my mouse and open a new window the paste the link. Very annoying and time consuming. How do I fix the continual tabs crashing problem?

Greetings, every so often I'm having an issue loading pages for certain sites that aren't sketchy at all. The most recent one is TireRack.com. I'm shopping for tires for my car and Firefox is loading all the other sites I've visited but it won't load any page from TireRack. They are a legitimate shopping site. It happens from results of a Google search but I've also tried typing the main page of the site's address into the address bar, clicking various other links that display below the actual search result that go to other pages within the site, etc. The site loads fine in both Chrome and Edge. This happens every so often and it's always a legitimate site and the exact same behavior. I can't recall any other specific sites at the moment but it's enough to have me pretty irritated today as when I'm shopping I like to have multiple tabs open with all my options for comparison and price considerations and today I have to have one of them open in a different browser which makes it much more difficult to keep tabs on especially where I'm used to only having one browser open for all instead of having to remember that one of my options is open in another browser. I have glanced through my browser setting as well as my windows security settings but I could spend hours in there trying to figure out things and potentially breaking other things myself, which I don't like doing. Any suggestions or other info on what could be going on will be much appreciated, and thanks in advance.

Ray.

I can not log in to Outlook anymore on my computer when I use Firefox, but it is possible when I use Edge. But I prefer Firefox. What to do about this?

Lately, I have been getting a pop-up error when I start and close Firefox. The error reads: "XULRunner Could not determine any profile running in backgroundtask mode!"

I have found posts such as this one: https://support.mozilla.org/en-US/questions/1398228 and other posts suggesting to disable the scheduled task in Windows Task Scheduler, but none of the solutions have worked thus far. Anyone know of any other solutions?

Bonjour, Hello,

I contact you because, even without an adblocker, Youtube is very slow with Firefox navigator. I don't understand why and I don't have this problem with Google Chrome ? Fews years earlier, I never had this problem with slow Youtube when using Firefox Navigator. I don't know if the problem comes from Youtube or Mozilla and I contacted both of them.

Thank you.

Bonjour,

Je vous contacte car, même sans bloqueur de publicité, Youtube est très lent avec le navigateur Firefox. Je ne comprends pas pourquoi et je n'ai pas ce problème avec Google Chrome ? Quelques années plus tôt, je n'avais jamais eu ce problème de lenteur avec Youtube lorsque j'utilisais Firefox Navigator. Je ne sais pas si le problème vient de Youtube ou de Mozilla et je les ai contactés tous les deux.

I have 750mb Claro fiber internet, directly on the cable. I updated Firefox. My internet dropped to 300/340mb. I complained to Claro. They tested by connecting another computer to the cable. It gave 800mb. I installed Chrome. Speed ​​was 900mb. What to do in Firefox to regain speed?

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?
