It's 0.9.3 and I dont think Firefox is so great that I'm going to reinstall it on the off chance it fixes the bugs in it. The way it brings you back to the top of a page when using the back button is also a major drawback.
That is wierd, because mine does not bring me back to the top of the page when I use the back button. It takes me right back to where I was when I changed pages. I think you have gremlins. I hear they are hard to get rid of, but you can claim them as dependants on your taxes :-)
