Firefox goes Spinning Beachball all of the time under Mac OS X 10.7.5. I have to force quit it!
It does this all of time. I'm using Chrome right now & it doesn't! I have to stop using the browser that I have used for many years & now I'm using Chrome. Gosh, no issue like that!
Additional System Details
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17
please upgrade to the latest Firefox and also maybe this article will help you:
