Definitely have the lockups in Firefox newest version isolated to happening only when Adobe Flash Player is installed. If I uninstall Flash, Firefox is totally stable and never crashes or locks up. If Flash is installed then I get very frequent lockups requiring a Task Manager kill of the firefox executable to end the drama.

I want to like Firefox but this kills it for me.
 
No trouble here with FF 42.0x.

Which version of Adobe's software are you running?

btw Adblock Plus, Malwarebytes, CC Cleaner and selective use of NoScript have helped my interwebz experience irrespective of browser.

does the same on mine.

I switched to chrome for flash
(ex watchespn.com)
and use firefox for regular browsing

Can you give a link to a web page that is causing this behavior for you?

I haven't noticed anything like that on my end so far.

I'm running FF 42 with Adobe Flash Player 19.0.0.226.
 
Firefox has been super buggy for me, locks up, and crashes for the past 6-8 months. Getting ready to switch to something else, which pains me, since I have used FireFox for years now.

I agree. Don't know if the "A" team moved on and we now have the "B" team working on Firefox, but there seems to be a lot more issues over the past year. They need to work on getting those fixed and FF stable, before adding any new features.
 
Another thing: for whatever reason, I also start having flash issues after it automatically updates a few times. I now have it set to notify for updates and I do a clean uninstall and reinstall of flash when there is an update.

It's a real buggy piece of junk software but the internet runs off of it, so it's needed...
 
watchespn does it for me.. I would get random slowdowns where I couldnt type into a second firefox window.
literally firefox would be frozen game would still play
but no typing clicking etc.
once every 5 min or so.. for 10-15s


Now I just do the watching in a chrome window

and regular browsing in firefox.

Seemed to mainly happen when I had 2+ firefox windows open.
 
I'm running Firefox 42.0, the current update. I want to like Firefox, but it seems to be quite a useless freeze-o-rama piece of nullware if flash is resident on the system. This is a Windows 7 system, not 8 or 10.

If you have already done that, sorry that's it for me.

Only other thing I could recommend is an addon like flashblock, to regulate when flash runs: https://addons.mozilla.org/en-US/firefox/addon/flashblock/?src=ss





Did this and trying it again for a while. Of note is that before the above and now after the above there was and still are two instances of FlashPlayerPlugin_19_0_0_226*32 that run in Task Manager when Firefox is running.
 
Disable the flash protected mode. It should fix the issues. Flash plugin is the protected mode that needs to be disabled; when they issue security updates, their native plugin container conflicts with Firefox's built in native plugin container.
 
Update:

disabled protected mode per Drew's advice. Works initially but after opening several additional tabs while browsing Firefox eventually comes to it's knees and finally stops responding again.FlashPlayerPlugin_19_0_0_226*32 no longer shows in the task list, with Firefox's own plugin container showing instead. Task kill required to end the drama.

I am going to try to download Firefox 64 bit, as I think the version it is giving me when I select select the win7/win8 from the drop down on the Adobe site is 32 bit.

The whole reason I even started using Firefox is because it was the only browser that would still allow connection to the local web interface (intranet) of my ancient Cisco/Linksys WRT 120N wireless N router (technically, faux N...) due to the router setup pages being https (SSL) and coded with the "weak ephemeral Diffie-Hellman key in Server Key" error discovered a while back for SSL. IE and Chrome no longer allow connections to a server with the weakness with no option to bypass for a trusted server on the local intranet. Firefox also would no longer allow it BUT there is the option to go into ABOUT:CONFIG on the address line in Firefox and change two parameters under the list of parameters for how Firefox handles SSL3 connections, basically disabling them (both boolean's so user-change them to FALSE) which would then cause Firefox to allow connection to a server with the SSL security weakness, i.e. weak Diffie-Hellman key.

Not a huge deal, and I should update to a new router anyhow think I got the WRT back around 2008 or 9, but these days it's just my laptop and a wireless G printer/copier/fax on the router and I'm limited to G speeds anyhow as long as I have the G printer (and have no need for better printer right now).
 
I was a long time Firefox user until September. That's when I started having major issues with Firefox and flash. Even though one of the Firefox updates fixed things a little bit, chrome doesn't give me any issues at all. So I now use chrome as my primary web browser.
 
FF for me was grinding to a halt using Adobe Flash. Went to Chrome, worked for while well but similar slowdowns came. Then went to Opera browser and have been lucky so far. Some slowdowns but would clear sometimes with a reboot. Hope it holds. Windows 7 Pro 64.
 
FF doesn't freeze here, but occasionally, YT videos won't load...
A restart of FF fixes it immediately... wonder what's up with that...

about:plugins shows all plugins are up to date...
