RIP Firefox

I've finally decided to express my intolerance to the constantly growing and getting heavier and slower Firefox. The last month confirmed the browser trend - becoming more and more memory expensive with each new version. Long ago I've started to think about migrating to something better but I was so sentimental - NOT ANY MORE.
The last fox was sent to its final trip after its today's extended memory invasion.
I just can't find it normal, can't understand it and tolerate it - one single instance of a browser window with only one tab opened, with one page loaded (the page contained 0 flash objects, 0 javascript inclusions, regular number of text lines and two images, the page was NOT reloading itself at all) ate 368MB of my PC's memory. When I've decided to close the browser window, it immediately disappeared but the firefox process remained alive and kept eating memory. Just before I've killed the monster, it was swelled to 420MB size (I've ignored plugin_container.exe - it was .... still... relatively small ).
The situation was not a precedent in past 3 months.
I've had enough!
Forgot to mention that I didn't load tones of firefox extensions. It was running with only one of them, that I had found pretty useful in my daily work - Tamper data. That's all. The bookmark list was big, but there was only 3 RSS feeds that eventually will need to update form time to time

At that moment I'm running Google Chrome with the same amount of bookmarks, with one plugin for RSS integration and the browsing experience is SOOOOOOO different.
I should have done this long time ago.

RIP Firefox!
