Tested 3.6 this night. And I still cannot understand the hype around it, even more so since the problem I mentioned above (and which several people on this board coinfirmed when 3.0 was released) is still existent. I then checked in the task manager and saw that the browser was listed with taking a hopping 1.2 GB of my 2 GB RAM !!! At that time, after maybe 10-15 minutes of browsing, my system already was extremely slow again and stuttered, with my HD working overtime shifts, and as a further investigation (via IE8

) and Googling revealed, the symptom is existing for sure. Some refer to it as a memory leak, which it obviously is, others try to declare it as a feature. Well, no matter what priorities amazing features like bogging down the system have in Firefox, I surely do not tolerate any brwoser, ever, being such a system hog, feature or not.
Since I tried 3.0 and 3.1 (or 3.2, I am not sure), both RAM bars and memory size, graphics card, HD, DVD have changed over here. Also several system reinstalls.
Ah, and after I deleted Firefox again and scanned my system with having forgotten to delete the Temp folder first, my scanners gave me 5 alarms again. Which happens almost never when using IE8 in high security settings and Java and active script deactivated, and the temp folder also not deleted (which it usually gets, when closing IE8).
This was probably the last time ever I tried Firefox, I did so with several versions, even early one (2), and all tests were very quickly very disillusionising. To me it just is hype, sorry. Chrome is no altermative, since it is a Google data kraken, leaving them knowing more about yourself than you know yourself. So for the forseeable future I stay with IE8. Against popular belief, over here it has shown to be the safer and more trouble-free browser, and repeatedly so.
