Vista is my OS.
Firefox is current. No spyware malware or virus found.
Hardware accelerator is unchecked.
All plug ins are current.
All extensions are current.
When I have more that one window or tab of firefox opened it crashes or does not respond at random times.
Firefox crashes or does not respond at least once daily or every other day.
I have completed all the steps this lists. https://support.mozilla.org/en-US/k...
What can I do to prevent firefox from crashing or not responding.
Thanks for your time and help.
