Hi.

My Firefox on my Mac OS X Leopard(totally upgraded) slows down when there are a lot of tabs in the window. By the way. Don't get me wrong folks. I'm not talking about page download speed. I'm talking about scrolling in the page or video viewing when the video is totally downloaded.

What's the problem here people? Is it about Firefox or my Mac OS X installation? Also what do i have to do to fix it because it's really a pain in the ass.

Having lots of tabs open in Firefox requires more memory - it's not really a problem with your computer or your FF installation.

If you need to have loads of tabs open at once I'd suggest you upgrade your RAM,

But my RAM is already upgraded to 4G GBs DDR2. And the problem is only happening with Firefox. Safari works perfect with dozen of tabs opened. But I can't use Safari because I made a mistake that now Safari forgets my log ins.
