Newest version of firefox keeps crashing every time there is a pop up or a video ad on a page

more options

I am very displeased with the new version of Firefox. My browsing sessions keep crashing, causing me to close/reopen the session every 5-10 min. It seems to happen when there is a video ad or a pop up on the page. When I restart the session I get an error message: We're sorry...cannot restore session. If i hit exit the session is restored. I tried to refresh the browser settings and it did not work. There is no message or alert that prompts me to changing anything with my CPU.

This is most annoying and is inhibiting my work. To satisfy the requisite IT stall questions: I am using a PC, Windows 8, and yes- all of my updates are current and I refreshed my Firefox. If this cannot be fixed I'm going back to googlechrome.

These didn't help. I am not going to post my information on a forum.

The problem still exists. It appears to have an issue with pop ups or flash applications. After Firefox crashes, I have to reload and the page will work - until another flash app or pop up occurs.

I attempted to use the flash blocker, but it inhibits my ability to use my CPU.

This is an issue with the update. It needs to be fixed

The screen shoot is in greek but i tellig you the first thing you need to do is to go to about:preferences#advanced and turn off the automatic upgrade before you uninstal firefox completelly from your system

Then use ie explorer to download 38.0.5 version of firefox from

Is the fastest version I have tested without any problems and leave the beta testing to the others, trust me i even used workstation to install multiple operating systems and tested many x64 browsers all together they cant beat 38.0.5.

Is there a particular reason that you are using the Firefox 41 beta version?

I understand that you don't want to post your Crash Report ID's (which really don't contain any personal information) - but did you even view your Crash Reports to see if the problem is clearly mentioned? Sometimes the 'at fault' module is in the title of the crash report, or is clearly identifiable with a little bit of reading.

Please try the latest Firefox 40.0.2 release version and see what happens. latest release version
