When I open up FireFox 4 (both in normal mode and safe mode) it crashes within a few seconds. It is a fresh install of FireFox 4 but I also have FireFox 3.6 installed as well. The report that was given is:

Chosen solution

1. You have a pre-release Beta 1 version of what will become Firefox 4 in like 5 or 6 months. Unless you are intending to test it for flaws and report those flaws to help in the development process, don't use it.

2. Did you create a new Profile for 4.0b1, and are you using that Profile with it? That isn't done automatically when you install 4.0b1, and those of us who have been doing the "testing" for many years consider a new Profile as the basis of doing out testing. http://support.mozilla.com/en-US/kb/Managing+Profiles

IMO, Mozilla is making a huge mistake by directly offering these beta versions to the general public.

Also IMO. if you want to play with 4.0b1, use the Portable Firefox 4.0beta version to minimize any conflicts with a currently installed version of Firefox, and to eliminate the need for creating a new Profile for 4.0 Beta #:

Download Firefox Portable Test to your hard drive and double click the FirefoxPortableTest_4.0_Beta_#_English.paf.exe file. The entire installation (including a new Profile for "Portable") will be self-contained in the \Program Files\FirefoxPortableTest\ folder and won't interfere with an "official" version that you already have installed. Your Profile will be in the \Program Files\FirefoxPortableTest\Data\profile\ folder. The "down side" is that Firefox Portable won't launch if any other version of Firefox is already running. http://portableapps.com/apps/internet.../test

I have a new Toshiba Tecra laptop with Windows 7 pr0 x64. Firefox installs fine but will not load at all. Immediate crash every time. I've tried every compatibility mode and elevating the priveleges, no success. I've also tried every other fix that other users have encountered and nothing will work at all. Quite disappointed FF has not recognized/resloved this issue. It's not like Win7 x64 was released yesterday.
