Recently www.deviantart.com upgraded their website to version 6, and since then it crashes Firefox 3 every few seconds when browsing the personal watchlist area.

I have disabled all of my Firefox 3 add-ons and themes and run FF using just the defaults, but the crashing still occurs. It happens when I start removing thumbnail pictures from my watchlist area, and after removing about 2 it crashes within 5 seconds, every single time.

I have tried using Firefox 3.0.0, Firefox 3.0.1, and the latest Firefox 3.1 beta from here. I used only defaults, no add-ons or themes. All versions crashed. I thought perhaps my Firefox 3 profile had become corrupt, so I created a fresh one and tried it, but it still crashed in all versions.

When Firefox crashes it cannot even send an error report because it says "Cannot move crash dump file" or something like that.

I have no idea who to talk to about this. Their website works JUST FINE in firefox 2. I would like to know if others have experienced this problem, or know who I talk to solve the issue.

Why not trying talking to the people who run and/or use the deviantART website? You could post to the deviantART forums and ask if other people are having problems with Firefox 3. If you post on the deviantART forums then, unlike with posting here, you're guaranteed to reach people who actually use the deviantART website and probably have their own watchlists. (Following your watchlist link gives 'permissions denied' btw, which is to be expected really.)
