Does Facebook screw with Firefox for anyone else?

[darkstar]

I just recently made FB my 13th start-up tab in Firefox. But from then on, FF would have big trouble loading and hang easily.

I thought maybe I was up against some limit on the number of tabs, so I got rid of my 3 least used tabs, and the problem persisted. Got rid of FB tab, however, and the problem went away.

Added old tabs back in. No problem. Added FB tab, problem returned. Took out FB tab and added 5 more randomly from my book marks (17 tabs) and things run fine.

So what's going on with FF and FB? Is there something I can do in either to remedy things? Is this anything like a known problem?

1. My girlfriend tells me that

with Firefox, FB loses her contact address and asks her to confirm it. With IE, no such problem.

Personally, I don't use FB. I have MySpace and don't need two networking sites to hate. One is enough.
