I work as a webdeveloper and for that I'm using firefox with firebug. I have noticed in the last time that after 2 hours of work, the firefox.exe process needed more than 1 GB of my working memory! Even if I close the window, the process still remains in the taskmanager and the only thing I can do is to 'kill' the process. Any suggestions? I'm using Windows7 with 2GB RAM, FF 3.6.8 y normally i have opened 10 tabs.
