First of all, here's the link ------------------------- CoolIris Previews ------------------------- I hope this isn't considered advertisement, but this is a really cool add-on I just got, and it especially great with forums. Especially the renders, prem. renders, tutorial, and sig/lp forums. What it does is when you put your mouse over a link it pops up this little box, and when you put your mouse over that it creates a little java-based (maybe...I'm not sure) windows that gives you a complete preview of the page. I think it's really useful, so I thought I would share. BTW there's a lot more info on their page.
Also, going witht he preview theme. i use Tab Scope https://addons.mozilla.org/en-US/firefox/addon/4882 And als, fireFTP is a FF tab based ftp client. https://addons.mozilla.org/en-US/firefox/addon/684 And coloured tabs, which will groups colours together from the same site. https://addons.mozilla.org/en-US/firefox/addon/1368
