I have been using Firefox for more than 3 years now since version 2.. it is now on version 3.5. Not sure what you guys doing to improve it but it just getting worse and worse.
Firefox browser is quite often crashed or freeze when I clicked on a hyper link!? WTF ?? Also it ate up to 900mb of my memory ram after just 15 minutes of using. In addition, playing online video even worse, keep loosing sound and freeze for 1 or 2 seconds.
Now I am going to switch and stick with Google Chrome, and only use Firefox as a debugging tool (Firebug + Developer toolbar)
If you experienced the same issue, love to hear some of your thoughts!
