Respected Sir/Madam, I found a problem to use Mozilla Firefox (137.0.2 (64-bit)) on Windows 10, problem shows in attachment.

Already uninstall Firefox and reinstall it but problem not solved. After restart PC Firefox works and it browsing speed is very very slow but after close Firefox problem start again.

Please give me the solution. I am a die hard lover of Mozilla Firefox.

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.

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

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.

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?

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?

As the title says -- I can no longer save images or download files without Firefox locking up. Whenever I do, the window grays out, the cursor's "busy" animation starts up, any videos playing in Firefox at the time grind to a halt, and I have no choice but to close Firefox when the "This program is awaiting a response from you" error message pops up. Whatever I'm trying to save will get saved to my computer, but Firefox always freezes up.

I've tried updating Firefox, resetting Firefox, restarting my computer, clearing my download history, changing the download folder, running troubleshooting mode and a private window. I even tried downgrading from 137.0.2 (64-bit) to version 136.0 out of desperation, and even that didn't solve it. I'm running Windows 11 Home, and this problem has only started happening in the last few weeks.

Any help would be greatly appreciated!

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?

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.

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?
