Firefox Support Forum

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

After one of the updates a few months ago, I have started to have trouble with firefox. After a while if I try to open a new tab and type in a link, the tab will try to load forever and I will not be able to open any more as doing another tab and typing a new link will have the same problem. I found that at first I could close the browser and reopen it to have the tab fully load and refresh whatever was already open, but after a bit that started to have an issue too. Most times now if I shut down and relaunch firefox within a few minutes the browser will open with all of the tabs open but they are all blank, with no links filled in, pages loaded, or anything. If I close and reopen after that then it only opens with a "new tab" page and everything that was open is lost. None of the more recent updates for firefox have seemed to fix this issue.

Thank you.

I like Firefox and am using it for years, but I cannot accept lengthy loading time. I have a fast and stable internet so this is not the problem. Please let me know what the problem is and how to fix it.

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?

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

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.

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.

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.

I've been using Rightmove Professional on Firefox for ten years plus but now suddenly it's not working correctly as the viewing windows no longer slide. Rightmove say it's due to an update by Firefox and advise to switch to Chrome but I really don't want to - will this issue be fixed? Thanks

I get the following two error messages when I click on Foxfire. Couldn't load XPCOM; and Entry Point not found; followed by this:  ?Nan@Decimal@blink@@SA?AV12@XZ could not be located in the dynamic link library...

I tried to uninstall the program, but got the same two messages and it would not let me. I downloaded a new version and I'm getting the same messages. Everytime I start my computer, I get the same two messages and have to click out of them to keep going. I've installed another browser, but at this point, I just want to uninstall Foxfire so it stops popping up with error messages all the time.

Anybody know how to resolve this? Thanks.

Hello,

After updating Firefox to version 127.0, I started having problems with the playback of some media files. In particular, audio files with the .wav extension do not show the playback time and the file cannot be played. I can play the same media files in previous versions of Firefox and other browsers (e.g. Chrome) without any problems.

Since I think the problem is caused by a browser update, I would like to ask for your help. If you have any solutions or feedback on this issue, please share it.

Thank you.

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.

I'm getting this Server Not Found page error with the very irritating "Hmm, We're having trouble finding that site" black screen with a doubleclick.net web address. I'm getting it a lot trying to visit totally legit sites and it's pi$$ing me off. It's not happening in Chrome or Edge but I don't like using those for other reasons. Would like to know what's going on with this crap. It used to be only once in a while and a couple of clicks to other links would get me around it but now it's happening a lot and won't let me get to the intended site at all. Very frustrating!

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

Hello, On several occasions over the past couple of months, maybe after a recent update, Firefox will not process any web page. In fact, if I try to go to another tab that I had been using, it will not refresh those web pages. However, in most cases, if I try to open in a new window, it works (though it did not just a minute ago). This is very annoying because if you have a couple of tabs open to certain locations, you have to copy down the pages so you don't have to remember where you were in your work. I would imagine that it would be difficult to duplicate but here's my info below. I will be glad to answer any questions you may have.

Thanks!

Ron

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.
