This keeps happening I will be on a random site and crash FF goes away. Next thing I am getting a "Do you want to restart FF" or Quit message. I normally hit the "Restart" but it make no difference. I have ran with all ad-dons disables, I have Flash Killer and only have the browser version installed. All my programs are up to date I use Secunia PSI, and Kaspersky Software Updater to double check that everything is always updated and current. I stream only in HTML5 so I don't have to deal with Flash. I do have a fair amount of ad-dons like Ghostery, Add Blocker Ult, No Script, Flash Blocker, Cookie Monster, Default User Agent, and Simple Site Blocker and Leech Block since Simple Site is now full, no longer able to block sites I need blocked. As I said this still happens with them disabled or still running and I can't have FF closing in the middle or work or when I am streaming an important video (not talking movies, porn, etc but work related) I need this to work and it not just streaming when it decides to do what it wants when it wants. Also It has issues with closing the when I want to log off or need to do something else. FF refuses to close and the amount of system resources is extremely high in my view we are talking 999,999k. Hitting End process does nothing at all the only way to close FF is to restart the computer, and once its back up if you open FF guess what. Its going to crash and or refuse to close and your back where you started at. I have created new profiles until I have had to stop due to just having too many, I think having 15 FF new profiles is enough to guess that is not the issue its not working. Worst of all their are times when my mouse does not want to work correctly with FF open and wants to go skipping across the page I have to force it to do what I want it to do. (Cordless by the way) not sure if this is resources issue or what but its becoming a pain too. I run scans with Kaspersky Total Security 2016 it never find anything wrong, I don't trust it. I installed and ran Malware-bytes and Rogue-killer and both of them found things that Kaspersky Total Security 2016 keeps missing, including an large number of FF profiles. Their was an issue with HitmanPro Alerts it kept becoming infected and was coming up as a Viruses so I simply got rid of it and that issue went away along with my money. But now what to do about FF and its issues? I cannot believe that FF is this buggy and has this many issues every update something goes wrong and it crashes goes down. I switched from Google because I hate the Spying but I don't see much difference between FF and them. At the very least their program did not implode every hour or so with suggestions that off little to no help to fix. Win 7 Enter, with 8gig RAM 12TB storage, office 2013 all updates applied and all programs current and up to date nothing out of date no malware or hardware that can be doing this on my end that I can find.
