If there is still a problem, Start Firefox in Safe Mode https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Just in case the above doesn't fix the problem, would you please take a look at this article :

After a script stalls in FireFox my entire computer runs very slowly until I reboot it. Task manager does not show any process consuming CPU resources, The computer just runs slower and slower the more times I have to stop a script in FireFox. Restarting FireFox does not help. The problem occurs in safe mode as well.

Hopefully the attached pictures or warning messages can be of some use to fix the problem. If they are insufficient then I suggest the development team add a lot more detail to the error messages. Also ask if the user wants to report this problem to Mozilla and give the option to have the error message automatically send a log file. At a minimum the error message should include a path pointing to a debug log detailing the error. The log could optionally include a link to send the log file to Mozilla.

I'm running XP 64 Pro. FireFox blocks these plugins and wont let me start or update them.... Microsoft .NET Framework Assistant Adobe acrobat plugin for FireFox 11.0.8 Silverlight plugin 5.1.40416.0 VLC web plugin 2.0.2

It would be really nice if you could tell me the name of the processes to kill in Task Manager so I wouldn't have to reboot so often. Any suggestions would be greatly appreciated !  :-)

You may want to try the 32 bit version.

fyi: June is the end of support for XP

Thanks for suggesting to try a 32 bit version. But of which did you mean? XP or FireFox?

I'm currently running the 32bit build of FireFox version 52.7.2 XP64 pro is sooo much faster than XP 32 bit. So it is not likely I'll be downgrading to 32 bit XP even if I did have the CDs for it, which may not be too easy to purchase this late in the game. If there is a 64 bit build of FireFox available I would be happy to try that. Is there a link for it?

Can anyone say which thread process to kill in Task Manager after I already stopped the troublesome browser script, and exited FireFox too, and then the computer is still running slow?

How can I send a request to the FF developer team to add more details, and logging, to their browser warning messages which I posted previously?

Win64 Firefox any version (including current at www.mozilla.org/firefox/all/ ) will only run on 64-bit Windows 7, 8, 10 so even if the WinXP or Vista user had the 64-bit version of OS you can still only run 32-bit Firefox anyways.

Since you have a 64-bit CPU if you were use or dual boot a 64-bit Linux ditro then you would be able to use 64-bit Firefox.

Firefox 52 ESR is pretty much almost at End Of Life (Fx 52.9.0esr on June 26) and 53.0 and later does not run on the EOL WinXP and Vista so there will be little reason for Mozilla to add anything for Firefox 52 ESR at this point.

How do I update to something newer the 52.7.2 ? I went here ... https://support.mozilla.org/en-US/kb/update-firefox-latest-version and followed the instructions but it just wanted to install the same version I already have.

There is nothing newer than 52,7,2ESR You need to download from here : https://www.mozilla.org/en-US/firefox/organizations/all/

As I said Firefox 53.0 and newer including 59.0.1 requires Windows 7, 8, 10. This is why you are served 52.7.2esr.

The Firefox 52.7.2 esr is the current version for Fx 52 ESR. Fx 52.8.0esr will be out on May 9th.

I downloaded the latest from the link which Pkshadow shared. The problem remains, still crashes and stalls. Note the fresh screen shots of FF problems attached to this post I can't over emphasize the need for a good log file to solve problems. Hopefully the upcoming release will include advanced logging.

At the point where FireFox stalls or crashes, as shown in the screen shots previously attached, would be a great place to add a comment about typing In the address bar, about:crashes<enter>. Also would be a good place to add a comment warning about third party drivers being rejected by FireFox, and a link to identify the list of external drivers being rejected.

Thanks for all the support each of you provided. I really like the timely responses from the team :-) Kudos.
