Firefox Community Forum

Please tell me why this happens daily. I cannot access my laptop after a break at 10:00 am..... for some reason, Firefox freezes, only thing that will work is the Chrome browser.

Dear Mozilla Support Team,

I hope you're doing well. I'm writing to request a feature enhancement for Mozilla Firefox that would greatly improve the user experience, especially on lower-end or older hardware.

Currently, whenever I open Firefox after closing it, it takes about 2–3 seconds to launch. In comparison, Microsoft Edge opens almost instantly due to features like Startup Boost and background mode, which allow it to keep essential processes running even when the main window is closed.

I would love to see similar functionality in Firefox — such as:

An optional "Startup Boost" feature to keep Firefox running in the background for faster launching.

A tray icon mode that allows Firefox to stay running in the system tray instead of closing completely.

A setting to allow background updates or session prep on startup/login.

These additions would make Firefox even more competitive in terms of performance and convenience.

Thank you for your continuous efforts in maintaining a privacy-respecting and open-source browser. I truly appreciate your work.

Best regards, RIYYAN AMIR

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

OS: Xubuntu 24.04.2 Apache: 2.4.58 Firefox 137.0.1 and earlier

In general Firefox is working. However, after every update, both major as well as point releases, where Firefox updates and then restarts itself, it almost always starts up and displays the homepage (local page on my machine) but is completely unresponsive. It will not load a locale or a remote page. I can kill all running firefox processes and then manually restart the browser -- with the same behavior. I have discovered that if I wait for around 10 minutes or so, then the browser starts working and continues to work just fine until the next update. Once past this initial update wait, I can kill/restart the browser, reboot, etc. and Firefox is responsive. It is only immediately after the updates that this problem occurs. This has been going on for at least the past six months or so, but is new behavior that didn't exist prior to that. This isn't a show-stopper, but it is very frustrating.

Any suggestions.

Hello.

I have the latest version of Firefox (137.0) on all of my computers, but it all of a sudden became unresponsive on my laptop:

MacBook Pro 13inch M1, 2020 MacOS Sonoma version 14.7.5

The homepage loads and I can go into preferences, but pages won't load, and then it freezes up and I have to force quit. I tried re-installing Firefox, but that didn't help.

Any other suggestions would be appreciated.

Thank you.

I'm unable to do much with Firefox now.

Chrome works fine. I'm using it (unfortunately) now in order to contact you.

When using FIrefox, it starts and does some partial loading, but then stops responding. On the default Firefox startup, about 1/2 of the "thought provoking story" pictures load. If I go directly to Youtube, for example, again....it starts loading then "hangs".

I can't close Firefox either: the window closes, but it's still running. If I attempt to restart it after closing, I get a "Firefox still running" error (which also won't close it.) Windows task manager will shut down the 5-10 (it varies) Firefox processes.

Tried checking for updates. That also gets stuck trying (let it try for about 10 minutes). Don't see any "reinstall" option.

Tried "Refresh Firefox" (fails....Firefox won't close). Tried "Clear startup Cache)" (same) Tried "Troubleshooting Mode)" (same)

Should I delete it and download again?

I updated firefox just yesterday or earlier today idk and the right click menu is so long with multiples of the same and they DO NoThInG! Linux Mint 22 Cin. 6.8.0-55 Generic Kernel

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

I use Firefox with DuckDuckGo on Ubuntu 24.04, Gnome desktop. My Firefox browser window regularly freezes but can be unfrozen by simply repositioning the window. This is really annoying.

I also use Chromium on the same system and there are no issues.

Any ideas?

I have a new desktop i7 computer with 16 GB of RAM. Why are my Firefox browser screens locking up? I'm running Windows 11 Pro. I don't have this problem with Chrome.

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.
