firefox will not open after i use it 3 or 4 times i have to update to make it work ?

Using XP pro after a couple years firefox quit working. will not open, went to support tried everything including a clean install. after which it worked for a short while then won't open. click on icon nothing happens. downloaded 18.0 update and installed worked a few times then quit. created new profile but when i click on firefox does not do any thing. if i run the update installer it will work for a while then quit to make it work again i have to update again ant it will work mabey for 1/2 to 1 day. after i update when firefox opens then it will give me the profile box. after it quits it will not load the profile box until i update again.

hello, please do a full scan of your system with the security software already in place and few different tools like the free version of malwarebytes, adwcleaner & kaspersky security scan.

Which security software (firewall, anti-virus) do you have?

Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.


A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
