Firefox "Just Halt"

After I had upgrade my Firefox to 3.5.2 version, the nightmare was come. The Firefox often just halt and no response at all if I was right-click my mouse to download some of the photo.

I have been using Firefox for more than 3 years have no problem on it and "love" it very much. If the problem still cannot solve. I think I have to "leave" Firefox and looking for new browser.

I have really disappointed with Firefox with leave this problem happen for long time. I know I cannot blaim them, because this is free software. I appreciated but this problem make me to withdraw using Firefox.

Good luck for Firefox..... I have to leave you... bye bye
