Firefox Support Forum

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Reinder

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

After accidentally cutting power to my pc, Firefox has been crashing upon start. I've tried using Troubleshoot Mode, refreshing, reinstalling, and even manually deleting all my user data, but nothing has worked. These crashes do not appear in the crash logs, and happen instantly upon opening the program.

Oddly enough, using task manager to restart Windows Explorer stops the crashing, at least for thirty or so seconds (this is how I was able to try Troubleshoot Mode, as well as accessing logs). I have no idea why this is, nor if it's useful information.

I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

Hello,

FIrefox is not loading new pages from the home page- it will load history I've saved or previous tabs, but opening a new tab and searching or typing in a website won't connect. Uninstalling and reinstalling briefly fixes the issue but as soon as my computer enters sleep mode the same thing happens. IS there a way to fix this? It's been happening for about a week now.

Firefox isn't having a memory leak (RAM and CPU usage stays the same) nor is it maxing my GPU or anything like that. But if I watch enough of a 1080p60fps stream or enough 1080p60fps content in general (this stream is a notable offender: https://www.youtube.com/watch?v=W6OOnrx8g58), it'll start to slow down over time (generally a couple of hours) and [really chug and drop frames like its nobody's business: https://i.imgur.com/OmHqJ8a.png. This does not occur in Edge (the streams run silky smooth even after 2+ straight hours of watching), nor does it happen on other streaming sites like Twitch. It also doesn't happen in Firefox on my desktop.

Regular 1080p60fps videos are MOSTLY unaffected. The buffer wheel animation in most videos is choppy and moving back/forth with the 5-sec rewind/ff feature results in a short, choppy buffer wheel on a lot of videos(https://imgur.com/tm1AtkB), even if the video itself is mostly unaffected. Some more "intense" videos will make the fan speed go up. HD videos are *slightly* less smooth when in this state. Unpausing a video often results in a short buffer wheel before the video resumes if left paused for at least a minute or so. I also get a tiny TINY bit of frameskip on the occasional Twitter video while in this "state".

Its like the memory is "caching" something and killing the process clears that "cache", yet I have no idea what is actually doing this.

Refreshing the page/closing and reopening the stream stream has no effect, its like an affliction and will still be choppy when you reload. Restarting the Firefox session or killing the process the stream or a video is running through fixes it for awhile (even if the stream stilll drops more frames overall than it would in Edge), but it feels like I have an "allowance" of 1080p60fps content before these streams start to chug. Nothing else in-browser is lagging at all.

bold textExperienced Firefox browser session freezes a month or two ago. It seemed that some March/April '24 fixes/patches stabilized the app. They are occurring again with increased frequency. What should I do to avoid this problem or switching to another browser? Thx

hello when i write many cell code in google colab and then run all of them when output there and i want to scroll up from last cell code to go to top of page,i have lagging for scroll up in that and this problem just in firefox and in chrome is'nt problem thanks

Well, since I changed to a new computer with Win 11, videos on Facebook don't play right. They are videos that are posted by various people and real entities. They are not smooth. They start to play and immediately pause then jump forward then pause and jump forward. If I copy the link and go to Chrome, paste the link and play the videos, they are normal Never did that on my old computer. Any ideas why the videos don't play normal?

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

Samsung Galaxy S24 Ultra running latest Android update and latest Firefox update. I set Firefox as my default browser. I have un-installed all updates for Samsung Internet and removed all permissions for it. Disabling it is greyed out. Some apps that I use have links to websites. Too frequently, when I go to one of those links, the intro screen for Samsung Internet opens. Then, when I look at the settings in Firefox it is no longer set as the default. Then I set Firefox to default and go to my phone settings to see that Firefox is selected as the default. If I open the previously mentioned app and choose the web link, Firefox will open. But somewhere along the way, the default changes back to Samsung Internet and it's a vicious circle. I have posted in a Samsung forum but haven't gotten a reply that solved the problem. Please help. Thanks Mike

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

Sometimes a box pops up on the screen that asks if I want to block or allow something. Sometimes I have no interest in doing either, and just want the damned dialog out of my face. The page seems to work otherwise, but the stupid browser keeps the dialog over top of things, and clicking outside of it, and hitting Esc, don't make it go away. I think those actions used to work, and I think there, sensibly, used to be a dismiss option, but that seems to be absent now. There's no sense to trying to force me to make a decision I don't want to make, and doesn't even need to be made, and I want this thing to cut it out.

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

It takes forever for my home page (MSN) to load when I first start Firefox. Can that process be speeded up? I suspect there's a way to get my home page to load faster. Can someone help? Thank you, Firefox.
