Firefox won't open--crashes in normal and safe mode. Browser does not open at all, instead I get the crash reporter.

I have downloaded all current Windows updates and scanned my computer.

Chosen solution

Have a look at firefox crashes. It may help to update to the current Firefox 10.0.1 You may do that by going to say getfirefox.com to obtain the install file. Do NOT use any option of Windows or Firefox that mentions deleting personal settings, or you will loose settings including bookmarks and passwords.

One of the reasons for the very recent Release of Firefox 10.0.1 was to solve problems with startup crashes, so updating may help.

Glad to have helped.
Thanks for posting back.

I hope that your post indicates Firefox is working without crashing after the update to Firefox 10.0.1

Yes--that did the trick--thanks again! I hadn't realized that I could update firefox without opening the browser.
