Firefox Support Forum

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.

For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

Hi!

Every 10-15 days Firefox crashes on one of the machines.

The only error I have is the "No mapping between account names and security IDs was done" in the Event Viewer at the time of the crash.

Firefox and the system fully up to date. The system exhibits no other issues.

Windows 11 Pro, no domain, crashes happen on multiple accounts on that machine.

The user is not signed in at the time of the crash. They have been using the same add-ons for years, but just to rule it out, Troubleshooting mode was attempted to no avail.

AV has been completely removed temporarily to avoid any conflicts.

Hello, I cannot log in to Twitter/x.com with the Firefox browser. There is a constant loop when registering. Firefox browser does not connect Twitter/X.com.

Thanks for your Help.

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

After auto update this error message came up and will not allow Firefox to open. Earlier in the day it had also updated ( not sure to what version) and was working fine. Laptop was then shut down and turned off for aprox. 1 hr. I then turned it back on and tried to open Firefox and it again asked to allow Firefox to make changes to my computer to which I clicked Yes. It then would not open and this error came up. error message Platform version 127.0.2 is not compatible with minVersion >=127.0.1 maxVersion <= 127.0.1

Since downloading latest update, requested by the software, it takes 2 or 3 times longer to go to most websites, but it takes 10 times longer to go to a Youtube video. (Generally 10 to 30 seconds).

About once per week, I'll be using Firefox and it will stop working. I'll close it and open it again and it gives me an error message "The application "Firefox" can't be opened."

If I download Firefox and reinstall it, everything will work fine for another week and then it will do it again. I'm not doing the same thing when it breaks. It does it on both my Mac Mini (macOS 14.5) and my Mac laptop (macOS 12.7.5).

It just started happening in May on both. Nothing has changed on both that I can think of.

Since my last upgrade my You Tube starts up in the tiny right hand screen, fails to go to full screen or just disappear unless I close Firefox and restart often multiple times. This only happens on Firefox and only since the last upgrade.

There was an update posted today. I ran the update this morning. Now Firefox will not open.

error platform version 127.0.1 not compatible with miniversion >= 127.0

                                                                                  miniversion <= 127.0

Running Windows 10 Version 10.0.19045 Build 19045 64 bit Should I remove and reload program?

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Recently firefox stopped playing audio, I have searched through the settings multiple times, tried safari and google chrome and they both still work so here I am for help.

Running 127.0.1 (64-bit) on EndeavourOS, KDE Plasma, using Wayland. I've had severe crash issues and when troubleshooting I noticed this

Error: Failed to open Wayland display, fallback to X11. WAYLAND_DISPLAY='wayland-0' DISPLAY=':1'

pops up every time I start Firefox via terminal. Why wouldn't Firefox be able to open a Wayland display? Trying to force it with MOZ_ENABLE_WAYLAND=1 firefox doesn't do anything. I get the same error message.

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...

So i'm a basic PC user and not a Pro to solve Problems related to Web browsers. İ wonder if this happens to any one out there using Latest version of Firefox. (127.0.2 64bit) PS:İ use a app called user agent switcher to fix freezing or lagging or buffering. İ have read some where on the internet that youtube is doing it on purpose?. This happens only with Firefox but not with Microsoft edge.

Hi, Archived thread on this from 2023 has no answers. Why is this browser so slow now and why is it glitching with resizing my windows? Beyond a total reinstall - how completely inconvenient - I would like an EASY FIX.

NOTE TO MOZILLA - WHY DON'T YOU HAVE A SOLUTION FOR THIS, NO REASON TO GO TO COMMUNITY 'IN CASE' SOMEONE HAS THE SAME PROBLEM!!!

GET MORE REAL SUPPORT PEOPLE INSTEAD OF MAKING YOUR CUSTOMERS DO THE WORK!!

TAKES FOREVER FOR AN ANSWER, IF I EVEN GET ONE AND IN THE MEAN TIME I AM STUCK WITH PROBLEMS!!!!!

I cannot do anything involving a search, tab crashes. I have used Firefox for many years, and yes, I have updated to the current version. If I cannot get this resolved, I will have to uninstall Firefox and use another browser. Please advise. Thank you.

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.
