Ok firefox is just getting worse and worse after some random period of time (but usually it needs a few hours) [minor bugs] When freshly started (even with lots of tabs) it seems to work fine except a minor issue in youtube (I cant for some reason provoke the relative username list to appear when I try to reply to a post using "@" so I cant reply/refer to anyone unless he already posted something so that I could click on the reply button of that same post but that isnt so usefull because sometimes i want to reply to a person about something irelative to his/her post. I also cant click on the youtube video notifications (the clickable squares that appear in youtube videos sometimes when you have notifications enabled) because they simply do not appear Oh and the "playing audio" symbol doesnt appear on the tabs were musing is played or if it does it appears randomly to a tab that plays music and not to all of them. last but not least after some time passes and when lots of tabs are opened youtube videos (that had been paused for sure) seem to randomly start to play and since the playing audio symbol doesnt appear it very irritating to search through all the tabs to see which youtube tab missfired and pause it again. some times ALL the youtube video start to play simultaneously but thats kind of rare... though this happens randomly i noticed its frequently triggered when I set a youtube video (of an totally different tab) to full screen or exit full screen) [/minor bugs] Note that I uninstalled firefox installed the latest version deleted coockies and cleaned registry with Ccleaner yet it didnt help at all with the above... [major bugs] I have an amd fx 8320 16GB of 2400hz ram and SSD (swap file is on an HDD though which is in good health with plenty of space available... the swap file on it self is set to be low like about 2gigs) and my connection is a 30mbps down 3 mbps up (its a fine vdsl connection and doesnt have problems) my gpu is a nvidia gtx 650 ti with 2GB ram and my screen resolution is 1920*1080@60 while the CPU usage is under 80% the RAM usage is under 7GB the disk usage is almost none and I am not downloading anything etc firefox (in random times but usually after some hours have passed) gets redicoulously SLOW to the point of typing a letter and seeing it appear after 1 secod or so (im experiencing this right now) and it can be that slow without freezing for quite a few time... the rest of the OS and apps>>>> work FINE <<<<without being slow only firefox gets slow and less responsive Sometimes regions of a webpage get black or the entire wrbpage gets black and I have to scroll up and down to make the parts or the entire wepage reappear... though this method doesnt work everytime... if this symptom occures (i mean when webpages get black) firefox will crush usually withing a hour or little more... some times it "heals it self" and works find again without crushing though being less responsive... If I close firefox at that point it doesnt close normaly but it crushes... then I open it again restore my last session and everything workd fine and responsive for a few hours before these symptos strike again. [/major bugs] I have checked the RAM and my harddrives and they are healthy... now after posting this I will restart firefox because I was typing all this post with like 1-2 lagg in characters spawning
