Oversized Firefox 3

When I'm cleaning up my programs, I saw Firefox was increased to 720 MB! Is it caused by update over and over again? Should I reinstall Firefox 3?

by the looiks of things, it looks like you;ve only installed it a couple of days ago, I spose there is no harm in reinstalling it..

I found why it happened now:
My dumb torrent downloaded my movies to my Firefox folder.
I Did reinstalled Firefox 3, but my data, cookies are not lost.

so is it all fixed now?

IIRC, Firefox doesn't delete user data.

re-point the folder

[font=Microsoft Sans Serif, Helv]Go into your settings for your torrent downloader and point the downloads folder to a different location than your Firefox install folder. (preferably to a empty subfolder in "My Documents"

In general, it's not a good idea to store your "personal" files (documents, pictures, music, video, etc.) in the same folders as your installed programs.[/font]

Obviously something is wrong because mine is only 26 MB. Try clearing your cache and such.

Now it's the system's problem, my Firefox's folder is about 26 MB, but it said it's 3GB.
I'm going to scan my registry

Just ignore it. That add/remove program panel is ******** usually.
