So, i tried several things in the troubleshooting articles here in the Support, but none solved my issues.

Basically, after Firefox automatically updated to 40.0.2, the browser hangs a lot on opening and closing tabs, as well loading websites. When not doing anything, the CPU/RAM usage is normal, but opening or closing tabs uses a lot of CPU (most of the time, 100% of the CPU is being used when browsing) and it hangs every time. Scrolling down pages also causes the browser to hang. I tried disabling several plugins and extensions and I even tried using safe mode, but even in safe mode it happens constantly. I'll post the specs of my computer (not big deal), but remember that these issues didn't happen before the update.

Core 2 Duo, 2.93 GHz 4 GB RAM Windows 7 Ultimate 32-bit GeForce 8400GS

Please, did anyone find problems with this new update? What should I do? I've been using Firefox since 2007 and I love it, I'd hate to switch to another one.

When I bring up a spreadsheet online in google docs Firefox starts dimming the screen, others tabs run slow. The screen dimming will last, for 2-3 minutes, and then clear up, 2-3 minutes later it will dim again. The fewer tabs I have helps, but not the answer. IMO the problem has gotten worse over the few upgrades. I have an HP 2000 Laptop, CPU 1300.000 MHz, memory 7586 MiB.

Thx, Larry

Today I tried to launch Firefox from the Norton Support menu, It took more than two minutes to load. After that it takes two minutes on restart. When it finally runs all websites a lightening fast, except for Norton, which is very slow if at all. Three sessions with norton chat support have not improved anything and following the Firefox troubleshoote including reinstallation have not solved either.

(Sorry for my bad english, it's not my native language) Hello, it's been many months that I have a problem with automatic scrolling Firefox Maintain pressure on the mouse wheel can slide in all directions of the web page, very useful for long pages and also for very high resolution pictures.

Off for several release (from 40.0.0 I think but not certainty), scrolling stops and / or is extremely slow and choppy until the page is not fully charged. This is all the more painful if we wait for loading a heavy image on a slow site.

I tested with the Firefox Safe Mode and it changes nothing. Disable graphics acceleration nor solves this defect. Test a new blank profile ... Remove and reinstall Firefox ... Namely I met no automatic scrolling problem on Internet Explorer or Chrome.

As I visit large high resolution photo galleries, is often sucks having to wait finish loading before dragging on the page with the pressed wheel. I leave then your knowledge to help me determine the source of this defect.

P.S. Windows 7 x64 with ATI HD7870 2go

I'm running XP64 pro. The scripts on Yahoo will stall FF after a few minutes. Often I get the popup message that a plugin script has stalled and asks if I want to prevent seeing this again from the site. That's nice but every page on Yahoo is unique. So the stall happens on every page that isn't closed after a short while. The more stalls I get the slower my computer runs even though I use task manager to kill stalled processes. Then I have to reboot to clear out the FF remnants. Is there a way to kill remnants of stalled scripts without rebooting? Often FF crashes and asks me to send a report to Mozilla. Seems to me you guys should have a feature to enable extended logging for inclusion in crash reports. I have sent many requests to fix the problem. If you guys can't fix the root cause of the problem then can you at least provide a decent workaround so the memory doesn't get cluttered up with orphaned threads sucking up all my CPU power?

Recently Firefox has become nearly unusable. Opening links are *_sluggish_*... They eventually complete but it's annoying - I've switched back to brave for now. https://support.mozilla.org/en-US/questions/1175357 seems to be the exact same issue however nothing in the thread resolved my problem.

I'd like to stay with Firefox but it's not worth it at this time. :(

Any thoughts/help are much appreciated.

Firefox within the last month has started freezing every time on a Windows 7 laptop every time I try one of the above actions. I have tried "refresh Firefox", safe mode, uninstall/reinstall, nothing seems to help. Can't open prefs so I have not been able to turn off hardware acceleration. However, I was able to set up Firefox Sync which let me get my bookmarks to another PC and it looks like make setting changes on that PC affects this copy of FF so I <think> I've also tried turning off hardware acceleration. Nothing works. Especially frustrating that the options freeze. Firefox has worked for years on the affected laptop, is there anything I can do except give up and switch to another browser?

It is nothing in particular, but every since updating to Firefox 44.0.2, everything is hanging and the graphics messing up much quicker in my session. Even typing this, the cursor hangs and has to catch up. I don't know what kind of patch this was, as an update to 44 appeared just earlier last week, but it's made things terribly slow. Who else is having this problem?

This feels slow as molasses, especially when working with many tabs. It happens :

- On already loaded tabs (so you'd think just clicking on them would bring them to the forefront immediately).

- On a fresh install (a few weeks old).

- With no bookmarks at all.

- On a profile with only 6 extensions, including Tab Mix Plus.

- On a virgin default profile just out of install, with nothing else added.

I've tried to disable the real-time shields of my Avast Free anti-virus, to no avail. Note : I've moved my profiles out of %AppData%, but I don't suppose this is relevant.

I come from Opera (legacy version), which does not have that delay. Is this to be expected on Firefox ?

As an aside, long startup times seem to be the norm (9 to 16 seconds, in my case), and I'm not even sure this includes the Profile Manager startup time. I used to live in a world where launching a browser was immediate.

When attempting to open links in a new tab with the middle mouse button (MMB), Firefox freezes for a few seconds before going on with loading the webpage. Occasionally this happens also when searching for something through the address bar. Following suggestions on similar topics on the forums, I tried starting Firefox in safe mode, but the problem persists. In fact, after starting in safe mode, an additional problem appeared: after trying to re-load the tabs from my last session, Firefox froze on each and every one until the page had loaded completely. To emphasize and make the problems as clear as possible:

-Firefox freezes for a second or two when opening ordinary web links in a new tab.

-Firefox freezes for a second or two when searching something through the address bar.

-After starting Firefox in safe mode, opening links freezes Firefox until the webpage is completely loaded.

With versions of Firefox later than 34 (or possibly 35 - not sure) attempting to open a page link from an email in Thunderbird and occasionally other sources, results in Firefox 36 and 37 hanging for up to a minute before opening the new tab and page, so I am forced to use 34 to retain smooth operation.

I have not included the Troubleshooting Information as the problem does not relate to the Firefox version currently in use.

Facebook scrolling stalls on 2 laptops and 1 PC with Firefox 41.0.2. I've tried refreshing Firefox, deleting plug-ins, uninstalling and reinstalling Firefox, nothing seems to help. My other browser I.E. does not have this stalling problem when scrolling on Facebook. Mozilla does not seem to have a clean uninstall program and the Windows uninstaller leaves old Firefox data and registry items. So I'm currently backing up data on my main laptop and am going to reimage it from a prior clone and see if the older version of Firefox works better. Does anyone else have this problem or any suggestions that might help?

I get paid to listen to them so it not working really is pissing me off! Everything I've read and tired works for like MAYBE a month and then it's right back to doing it again. I am NOT going to constantly go back and do all that stuff EVERY month! I shouldn't HAVE to. Isn't there a way to fix this permanently? or at least fix it for 6 to 8 months or something?
