Well I never expected such a feedback, really. Thanks!
To address your questions:
-Doesn't really matter the site content as far as I know, that used to happen while loading new pages, though - both loading in a new tab and not. Also Youtube was making the browser lag both with and without the Youtube media center extension... As regards hardware acceleration never had a problem with that, my computer specs are too high to think of a problem with my cpu/ram, honestly.
-I am using the built-in AdBlock (AdHunter) in co-operation with AdFender.
-New tabs couldn't be added to the list, I could open just about... Nothing at all. Basically when I was trying to open something I was getting an error message saying domainempty (I was like "what?") allowing me to either click ok or the X button to close it (that should be in the report) and even if I did that it kept popping out until the browser crash.
-I sent I think 4 reports in a row, right before the Opening Post, with the 1st giving more details and even my email address to contact me.
Thank YOU for your support.
P.s.: Thanks Oliver, too.
P.p.s.: Since I think I can do Maths... I keep getting 19+1 which is obviously 20, but says 20 is incorrect... :o I tried to give ligical anti-typos answers such as 18 and 20 but that didn't work either.
