Very slow browser! Why?? (I've had to switch to Safari)

I have been struggling with a slow Firefox (3.6.12 I think) for months it seems. Yesterday I decided to completely remove Firefox from the computer and reinstall it from scratch. I did so with no change in speed. This morning version 3.6.13 installed and it is acting the same way. I suspect Norton 360 from hijacking the processor for scans, but it is not supposed to be doing that. What else could make my browser so slow? (Right now I am running Safari with no issues, Opera also operates with no issues, as well as IE.)

I have the same problem except that I am on Windows SP3. And 3.6.13 is even slower than 3.6.12. Starting or stopping it takes minutes. I removed all my cookies but did not help. IE8 is running fine. I also run Norton 360. Later.... I tried starting in Safe Mode - did not help. For example, bringing up NYTIMES.com in a tab is taking over 5 minutes and is still going.

Ron, That further convinces me that it may be an interface issue between Fierfox 3.6.13 and Norton 360. Thanks for your response.

I rebooted my system and now, 24 hours later, the slowdown has vanished - that is, Firefox is running fine. Reason unclear: I ran a Norton comprehensive scan overnight, finding nothing, then rebooted the system, and all is well!
