Hello Im using multiple firefox edition on my PC from beta dev to nightly, and recently in nightly and only nightly I've spotted strange issue that appears as window in window screenshot attached, outer x to close or maximize window does not work only the inner and mostly goes after F11 full screen and then return to normal. Troubleshoot mode and restart does not change or fix this.

Dear Support Person,

Yesterday, after being notified that an upgrade was available, I executed the upgrade to version 152.0.

The upgrade completed successfully with my eight tabs populating on the left side along with a new tab showing all the features of the new upgrade.

I opened my Gmail tab and my Yahoo mail tab. Eventually, Firefox froze up, saying it was Not Responding. I looked at Task Manager and saw that Firefox was continuing to grab up memory. I ended the Firefox process in Task Manager.

I then opened it again and deleted all the tabs except for one. It continued to grab up memory.

I then opened it in Troubleshooting mode. It errored out, and I sent the report to Firefox support.

The only thing that has changed is the fact that I ran the upgrade to Firefox. Nothing else has changed.

Firefox has been my go-to browser for years. I am using Chrome as my access to the internet now, and cringe every time I go into it.

I hope and pray that you can bring my Firefox friend back to me.

I am anxiously looking forward to hearing from you.

Take care and God bless!

~ Kyle P.S. I just tried getting information from about:support. I was able to copy the raw data and then the application crashed. I sent the Crash Report to you folks. The raw data I pasted in the Troubleshooting Information box.

Hello! Today I stuck with problem in my system: after minor package update, hardware acceleration was broke. In past, I stuck with same problem after total pc upgrade (AMD -> NVIDIA GPU, another might be unnecesary), and somehow I fixed it, but i dont remember what exactly fixed it. Can someone please help me turn hardware acceleration on this time? My searching the key arround didn`t helped, but i found in about:support line which notes that firefox unrecognized my videocard etc. My specs: kernel: 6.17.1-zen1-1-zen driver: nvidia-dkms-580.95.05-1 videocard: GTX 1080 TI DE: gnome 49 with Wayland

Tips that ive tried: Tried to make all as wrote in archwiki Tried to install an nvidia vaapi implementor Made some random steps from internet, without effect(maybe thats why hardware acceleration doesent work??)

theres also about:support page attached

I use a Mac running macOS Sequoia 15.7.2. Each time I attempt to login to https://music.amazon.com, Firefox freezes which then requires me to quit Firefox and restart. Therefore, I need to use another browser to access the site. What is the solution to this issue?

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

In 2024-25 Microsoft Edge gained the ability to limit the usage of physical RAM that the processes uses. Once that limit is reached tabs are put to sleep or are unloaded. So a user of Microsoft Edge could restrict the memory usage to say 1GB or 2GB or 3GB and so on till the maximum available physical RAM.

Does Firefox have such an ability? Is there some flag or settings in about:config that can be enabled for a similar feature to be used? Does Firefox have ability to put tabs to sleep once SWAP is started to be used? Is there some flag or settings in about:config that can be enabled for a similar feature to be used?

If none of one of the above is not available with Firefox then will Firefox add this feature as part of the browser in the future?

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen

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?

This started after the recent update. Any time i open more than 1 firefox window or try to move my window to a different monitor, the Menu Bar pops up and left click will be stuck only making the bar appear/disappear. I just have to close the second window because it becomes immediately unusable. I have the ui setting set to false but it still freezes new windows and doest let me click or type on anything. I've uninstalled and reinstalled, ran troubleshoot mode, got rid of extensions, reset my computer. I'm at a loss. Any help would be great

I booted the computer this AM and firefox is acting up. I can go to my email accounts (2), but I can't open an email. Both act like this. They will open with MS Edge and all other functions seem to work on the computer except for firefox.

I tried searching for a solution using duckduckgo and google, many of the links wouldn't open and some that did, just loaded re-loaded, but never finished. Pulldown menus, where they ask a question and click to see the anwer, don't work. They are frozen. Can see the cursor highlight the menus, however it will not allow any interaction with them.

I restarted the computer, there was an update, and I had it update. No change with firefox. I reinstalled firefox. No change. For the moment, I'm out of ideas. Anyone have any thoguhts about this, please help. Thanks in advance. Ken

I've been using Fire Fox for decades, but lately it is so slow, I thought there was something wrong with my Windows 7 ultimate. I've done full Windows reboot, to no avail. Then I see the internet t hat FireFox is starting to implement AI. I thought that may be the issue, but after looking into it, looks like that isn't an option with my old Win 7 OS. So if that isn't the problem, how can I find out what is bogging Fire Fox down? I keep a watch on my CPU usage, and the usage is going nearly to 100%, when it used to barely go over 10%. When I check the actual CPU usage, it shows as many as 15 or more items tied to Fire Fox.

Is this all a result of continued use of Win 7? I'm planning to move to Linux, but that will take me some serious time and effort. Gerald

I run a drafting site where we share shop drawings for contractors and architects: https://usadraftsman.com

Whenever I open these drawing preview pages in Firefox, the browser gets slow or sometimes becomes unresponsive. The same pages load completely fine in Chrome, so I’m trying to understand what might be causing this only in Firefox.

Most of the previews are large drawings or viewer embeds, so maybe Firefox is struggling with rendering them. I tried clearing cache and turning off extensions, but the issue still comes back.

If anyone has dealt with similar heavy graphics or rendering issues in Firefox, what should I check or adjust? Any suggestions would be appreciated.

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.

Everything is gone from the browser today. There is no content in the menu at the top right, except for keyboard shortcuts. When I type in the search bar, nothing happens, and clicking the + to open a new tab does nothing either. My account is still showing at the top, I am signed in and the profile looks fine. I can't "refresh" the browser from the menu, as that is not an option.

UPDATE: FIXED - Today, April 13 - everything is back - I guess Firefox fixed itself.
