- Windows XP SP3 (up to date with all critical updates)
- FireFox 25.0.1 (Note: Originally I had version 31 but a few days ago that stopped working)
- Norton Security Suite (the comcast version) up to date
- I have IE6 and Chrome 37 as backup browsers (Note: when FF stopped working, IE8 had also stopped working - page would open, only one system process, but page would never load)
Ran the following scans:
- SUPERAntiSpyware Free Edition
- Malwarebytes Anti-Malware
- Ad-Aware Antivirus
- Spybot-S&D Start Center
Found a few non-critical yet potential infections (nothing too crazy)
Symptom persists as follows:
- fresh boot of computer
- open task manager (no instances of FF)
- open firefox - process appears in task manager and immediately goes to 50%
(nothing opens and nothing listed in Applications)
- open a second instance of firefox - 2nd process appears in task manager
(still nothing opens and neither instance appears in Applications
(the two instances continue to run at a cumulative 50% CPU usage - one might be 15% and the other running at 35% - or both running at 25% each)
- open a third instance of firefox
(still nothing opens, and all three instances show in task manager processes and cumulatively run at 50% - example:15 +15 + 20 or 10 + 15 + 25)
Troubleshooting:
restored a drive image from May 2014
- Note: Dec 2013 I had done a complete FRESH new install of Windows XP in prep for EOL and installed all updates, including SP3, so the image I chose from May was only 5 months old, but I chose that one because of some of the other programs I had installed that month and didn't want to go through that again
- Note #2: I have drive image run a monthly PQI backup of my C: drive and my R: drive) I have two hard drives 300G each whereas C: drive is OS only and R: drive is all my downloads, my documents, my photos, etc)
- after the image restored, I tried to open FF and IE8, neither app was problematic. FF auto updated from what version, I don't know, but it was on 31 when I realized the problem was BACK. Also ran some WIN critical updates, and IE8 stopped working too!
uninstalled IE8 (rolled back to IE6 and now IE works - but obviously I can not live with IE6 - I need to update that!) uninstalled FF31 (and deleted all temp and profile account folders) and installed a brand new copy of FF25 - whereas I immediately force stopped autoupdater and deleted the update files so I could remain on FF25.
Now FF25 will open only on the second instance of the process (the first will always go to 50% CPU, the second will open and run between 0 and 10 CPU, and only one application in Applications)
- I have learned that I can kill the 50% process using task manager or process explorer and total CPU usage will drop down to 0% - 10%
I can open many many tabs without any problems, and I can right click a link to open a new window and all is good, BUT if I use the desktop ICON, the quick launch ICON or the START > Programs > Icon, then the NEXT process will go to 50% and no second window will open
I have seen dozens of forums that have reported similar memory issues, but none have been resolved.
Can you help me? I don't want to upgrade IE6 to IE8 just yet, but I will not use it for anything but testing until I can upgrade. Note: besides being painfully slow, I have been switching to Chrome, but I have never enjoyed Chrome.... I am using FF right now to ask for help.
Any suggestions?
