Firefox Support Forum

Have used Firefox for decades and suddenly it is having problems. If I surf around and have a few tabs open, some of them might crash. Firefox tries to restore them and sometimes it works and sometimes they just crash again immediately. I can go to Amazon and the page won't load completely so I can't do anything. If I try and close Firefox it won't close, it is frozen. And often, pages just load very slowly even though my internet connection is strong. This just started about a month or so ago. I have refreshed Firefox, updated it, and checked the systems on my computer. All my internal diagnostics returned "no issues." So it has to be the program.

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.

All of a sudden my web address bar at the top of the screen disappears when I open a web address and I have to push my mouse to the top of the screen to make it appear? Didn't used to do this.

Firefox 126.0.1 displays a very long name of a container completely in the URL bar.

Firefox 127.0 truncates container names

AWS long account and role names make keeping the long name very convenient (works with the 'AWS SSO Containers' Add-On

Firefox doesn't allow a web message to be sent but Google Chrome does. After filling out the form at: SPECTRUM URGENT: FUNDING FOR THE AFFORDABLE CONNECTIVITY PROGRAM IS RUNNING OUT, I could not send the message because I got a message saying, "Please enter a 5 digit zip code." but I did enter a 5 digit zip code! I copied the URL into a tab of Google Chrome and there was no zip code error so I was able to send my message.

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like it used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

There is an 8 years old question about it - https://support.mozilla.org/en-US/questions/1123903 How do I do it now with Firefox 125+ ?

Hello,

I'm a web developer working for the public radio show This American Life. We have a web audio player on the website and recently I noticed it stopped working in Firefox. Looking closer at the issue, I realized that Enhanced Tracking Protection is blocking one of the scripts (pdst.fm - Spotify). Because ETP is turned on by default, I'm hoping there's a way to help bring this part of the site back to functioning without bypassing the Spotify script, as currently that's out of my power. Any help would be appreciated.

Thanks very much, Mark Nicola

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Today all of the sudden, one of my computers running Firefox won't connect to Youtube at all. It says security issue with HSTS. It also says there there is nothing I can do to resolve it. Surely that can't be true. Youtube runs on every other computer in the office just fine.

Here is a screen capture of the message:

On a laptop running Windows 11, all videos I play in Firefox have been strangely dark and orange. Depending on their original appearance, this can make them unwatchable.

This only affects videos in Firefox, and only on this laptop. Chrome, Windows video player (and Firefox on my other devices) do not share this issue. The issue affects all monitors I connect the laptop to.

I have attempted: -A thorough search of Firefox settings and found nothing related. -Refresh and reinstall of Firefox -in about:config

   gfx.color_management.native_srgb to true
   Confirmed ui.videoDynamicRange was set to to 0

None of these has helped. According to all the evidence I can find online, a similar issue was caused by a problem with HDR video files and fixed in an update 2 years ago, but I am running version 127.0 and am up to date.
