I have updated my firefox with 4.0 and since than firefox blocs every site I go to it so that I have to restart my computer. What is the problem?

I have updated my firefox with 4.0. and since that I have problems. Namely, when I open some site firefox blocks it so I have to restart my computer. I don't have those problems with Explorer. Could U help me with this, because untill now I was very satisfied with firefox and would like to use it in the future.
With kindest regards,
Ljiljana Stevkovic

Due to security vulnerabilities, rolling back to Firefox 4.0.1 is not recommended. Firefox 3.6.18 would be the safer choice.
Here's the process to roll back:
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 5.
You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.
Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details.
Note: I haven't actually tried this myself!
