Firefox very slow with frequent unresponsive scripts

Running a very old XP pro with Firefox 52.1.01 and Firefox has slowed to a crawl. Total removal of NAV solves problem.  Restoring NAV and problem is back. I can barely type this. This is all new.

Help.

Re: Firefox very slow with frequent unresponsive scripts

Hi rfrischer:

Do you have the latest NAV v22.15.0.88 (Help | General Information | About)?

Firefox v52.1 was released in April 2017 and all Win XP and Vista users should have been automatically switched to Firefox ESR v52 (extended support release) in early 2017 to ensure they would continue receiving regular security updates. Do you currently have the ESR version of Firefox, and have you set Firefox to Never Check for Updates at Tools | Options | Advanced | Update or is there some other reason why you are still using v52.1?

I have the latest FF ESR v52.9.0 (released 26-Jun-2018) on my 32-bit Vista SP2 computer, and if you check for available updates at Help | About Firefox | Check for Updates you should be offered this latest ESR version.  Unfortunately, Mozilla is ending support for FF ESR v52 in a few weeks on 05-Sep-2018 (see the support article Important - Firefox is ending support for Windows XP and Vista) and after that date there will be no major browsers supporting the XP or Vista platforms.

Re: Firefox very slow with frequent unresponsive scripts

I actually had to remove Norton as my browser became useless. I did update FF to latest esr version though. I put Panda on which works well but is not Norton. I have computers with win 10 and Norton and work well but my legacy scanner and printer need XP which leaves me in a bind. I know people still on DOS for that reason. So, it appears that we will relegate all XP pro to non internet traffic  and use them for legacy equipment. I believe 6% of the computer world is on XP so one would think there is some market. Oh well. I don't believe the problem is solved though and I don't plan on reinstalling Norton to find out as it was a true pain to remove and had to actually go into changing the registry. Each reboot of the computer brought up a screen with a Which Program do you want to open "Documents" with. A real pain.

Hi rfrischer:

It might still be worthwhile to wipe any orphaned registry entries and files that you might have missed with the Norton Remove and Reinstall (NRnR) tool so they don't interfere with your new Panda AV. Run the NRnR tool in advanced "Remove Only" mode as instructed at https://www.norton.com/nrt (note the warning that "Remove Only" mode can uninstall other Norton products).  After the NRnR tool runs to completion and you re-boot your system just close the pop-up with instructions for re-installing Norton.  Any time you're switching AV products it's always a good idea to use the manufacturer's removal tool to remove the last traces of their product so they don't interfere with your new AV.

If your trial with Panda doesn't work out and you decide you want to give NAV another try or switch to another manufacturer like Avast make sure you also wipe any remnants of Panda after the uninstall with the Panda removal tool (see https://www.pandasecurity.com/usa/support/card?id=82011; a link to an older XP/Vista/Win7-compatible removal tool for Panda AV is also available on bleepingcomputer at https://www.bleepingcomputer.com/download/panda-antivirus-uninstaller/).

I actually had to remove Norton as my browser became useless...

This is a moot point since you've already installed Panda, but I find that Norton product updates delivered via LiveUpdate like the recent v22.15 release can sometimes corrupt the NS installation on my 32-bit Vista SP2 machine, even if I follow the suggestion in the product update announcements and run LiveUpdate and reboot a few times to ensure the product update is installed properly (see item # 3 of the Aug 2018 v22.5 announcement <here>). If I notice any glitchy behaviour after a product update I perform a clean re-install using the instructions I posted in freespace's thread Windows Defender Still Active, and I always decline the installation of Norton browser extensions like Norton Identity Safe, Norton Safe Web, etc. for my FF ESR browser.

If the CPU of your Win XP SP3 machine doesn't support the newer instruction sets like SSE2 then you were likely using the old NAV v21.7.0.11 - see dicere's thread XP Pentium III for further information.  I don't know if that's the case but an older NAV v21.x product could have caused additional problems with your Firefox v52 browser.

Re: Firefox very slow with frequent unresponsive scripts

Thank you. I did use the Norton Removal tool but it did not clear the registry entry that caused a "which file do you want to use" to open "documents". I used CCleaner which found orphaned registry files for Norton and removal of those fixed that problem. I tried AVG and it's twin Avast and both of them knocked out my Carbonite program and also caused a blue screen of death. So Panda it is for now I guess..

Didn't try Bitdefender but they don't support xp in 2019 version.
