Firefox Community Forum

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 have recently built myself a new computer and started running MS Windows 11.

I have a problem with Mozilla Firefox, where after a few days of being installed it takes 10 seconds or more to load (or to load subsequent new windows). It also takes a long time to switch from window to window or to close any windows. Opening and swapping between tabs is immediate.

Here is what I have tried:

- Switching off hardware acceleration. - Clearing the cache, deleting all other data and uninstalling the single add-on I use. - Creating a new profile. - Using Mozilla's own "Refresh Firefox" option. - Trying the beta version. - Probably some other stuff that I've forgotten about.

The ONLY way I can get things running at the proper speed again is to completely uninstall Firefox using an uninstaller (that also deletes all the registry entries), restart the computer, and then reinstall Firefox.

After setting things back up the way I want, Firefox will run nicely for a number of days, then will slow down again to the point where I have to uninstall and reinstall (whilst also deleting the registry entries).

It doesn't seem to make any difference whatsoever whether the computer has or hasn't been restarted during that time.

Does anyone have any idea why this is happening?

Hi -

I've been using Firefox for 10+ years, and have not touched my add-ons etc for years. I also regularly clear my cache of temp files.

That said, searching my (vast) bookmarks in Firefox used to be lickety-split, very fast. Then, it started slowing down, on both PC (Windows 10). Then, a little while later, it started on my laptop (Macbook with latest IoS).

It's now gotten so bad that I am searching my emails to find the links I'm looking for, rather than putting my browser into a coma for a time, because it freezes.

What is the problem, and how do I overcome it?

J

I don't know what is happening, but for the last few weeks my Firefox has been freezing on me, I know the cause is not the website(s) because I can browse them fine with other browsers, also when it freezes it won't let me close it, I even tried to close it using Task Manager, but I get an Access Denied when I click End Task, so I have to restart my PC.

Any ideas qhat can be happening?

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 have no problems typing in a textbox on most websites, but for some time now, when I type comments on YouTube, the box alternates between working and freezing about every 7 seconds. It will work fine for 7 seconds. Then freeze for 7 seconds, then back to working again.

Any idea what the problem is?

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?

Firefox constantly freezes up as soon as I right click on menus. In the expand/droppdown menu square box that pops up when I right click, is first just white (to text) then goes black and freeze. I understand the Win7 gets no support but does anyone know about this issue and can I go back to a version that does not do that? Preferably a version that does not hound me to update every 10 sec :)

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.
