Basically, when you go to any search engine site like Google or Yahoo. There's a search bar, you can type to search. When i go on Mozilla Firefox 4.0.1 and go to Google and search something, i found my Mozilla Firefox freezes when i type 2 or more letters while holding shift down (Holding shift and pressing any letter turns the letter into upper case). It basically freezes, where ever i hold shift and type.. example: Google, Yahoo and my address bar.

Reproducible: Always

1.Go on www.google.com
2.Type any letters while holding shift down
3.Mozilla Firefox 4.0.1 freezes

Actual Results:  
Nothing special, all explained in the details section.

Expected Results:  
Mozilla Firefox 4.0.1 freezes. I can't close or minimize the program. The only way to close it was to end the process through Task Manager.

Should'nt freeze...

Does the same happen in Safe Mode (http://support.mozilla.com/en-US/kb/Safe+Mode)? Also were you able to see it in Firefox 3.6.x?
