Firefox Community Forum

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...

Firefox occasionally stalls during a page load or refresh. A quit/start sequence of Firefox resolves the stall without further action. Is there a key sequence that invokes a restart: Firefox 140.0.2 (aarch64), MacOS 15.5 (24F74)

What's wrong with the new release?

Today i decided try the new firefox(140) since it's going to be ESR, but i'm getting hot-fan from a couple of tabs (particularly video streams). Second it's slower and seems to have 4second delay for shutdown..

The laptop is running linux mint with intel i5 (11th), tigerlake (iris xe) gpu. It might not be newest, but it shouldn't have a problem with regular web browsing.

Is it a bug? like it's not maxing my ram or cpu during use.

Constantly getting the following messages - "Not Responding." "This application is not responding. The program may respond if you wait. Do you want to end this process?" I am on my email or reading an article on my email and it goes blank. Also, I get "Restore session or start new session." The only way I can get to start my computer ( getting the password box ) is if I do Control Alt Delete many times.

Very Frustrating indeed!

There is a bug which was reported 3 month ago https://bugzilla.mozilla.org/show_bug.cgi?id=1959157. It appeared out of nowhere and I don't even know if it was fixed since then. But it is bugging me a lot, no pun intended. Any help would be appreciated.

Several weeks ago Firefox worked normally for me. I left for most of the day and when I got home Firefox no longer worked at all. Everything on my home page was gone and when I typed in websites - such as my e-mail program or Facebook, nothing ever came up. I'm not super browser savvy, but I opened the menu and under help was "trouble shooting mode". I didn't know what that was but figured nothing much more could go wrong with Firefox, so I chose that. I had to rebuild the websites I had in a row on the middle of the page. I didn't lose bookmarks, but everything else was different. So I left it that way.

Earlier today, Firefox wanted me to do another update. I thought maybe by agreeing to that, things might return to normal. Noooooooo. It's no better whatever. Now I don't know how to get out of troubleshooting mode to know if anything will work normally again.

I am seriously considering switching browsers, but I have a LOT of stuff bookmarked and that would be very intensive to build all those book marks in another browser.

Hi, when I use YouTube.com and i find this on "https://www.youtube.com/results?search_query=blue+connection+touch+the+sky" I get this popup message ""This page is slowing down Firefox",etc.etc. What happened to the browser? Thanks!

im using firefox on ubuntu, version 139.0.4. when i browse the internet using firefox, every some time the toolbar and the search bar "freeze" - i am unable to click anything, from the url, to any of the buttons. it takes up to like 1/2 minutes for the search bar and the toolbar to work again. i never had this issue before, neither on ubuntu (and other linux distributions), nor on windows...

This happens a lot all of a sudden. It used to say something like this "script is slowing down the page" or "page is slowing down browser" but it's only Outlook/Hotmail.

It's super annoying. Any fixes?

Thanks.

Firefox just keeps getting slower and less responsive. I've cleared the history etc and run my Avast cleanup premium which helped a little, but the other browsers just put it to shame. I hate to switch because I love the user interface, but............ its just frustrating. Windows 11 latest updates.

Do I need Firefox 78.0.2 (x64) and Firefox ESR (x64)? Also I noticed I have noticed a very slow startup. I have an old Dell Vostro 460 PC. I also did a Task Manager and noticed five Firefox process. Can I shut some of these down?

Thanks, Irv

Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

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 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.
