When I log into Firefox and do a search, or type in a URL, or click a link from one page to the next, sometimes the "back arrow" is greyed out, and won't let me click on it to go back to my previous page.  I don't know how to reproduce it.. sometimes it's there, sometimes it's not.

Reproducible: Sometimes

Steps to Reproduce:
1.Get into Firefox
2.Navigate away from a page
3. Try to go back using the back arrow.. but can't because the back arrow is greyed out.
Actual Results:  
The back arrow is greyed out and cannot navigate back to previous page.

Expected Results:  
Stayed on same page, but back arrow should be blue and clickable so that I could go back to my previous page.
