Firefox 1.5 is availalble now right here

And of course, you need some extensions to go with your FireFox. There are so many great ones: ForcastFox, Google Toolbar, TabFX, Web Developer. To install some of these old standards, go to Tools>Extensions and click to link at the bottom of the extensions window to "Find new extensions."

A new version of Firefox often leads to some issues with extension compatability. (E:Paul)'s fave, Live Headers is no longer available, but I'm sure it will be soon.

And with a major upgrade like 1.5, new plugins are available.

First up: Foxpose
Fans of the Mac OSX Expose feature will know what to expect here. Foxpoxe puts a button in your status bar that wil display all of your open tabs in a visual grid.

And Also Hotness: Tab Preview
This extension makes it so that thumbnail previews of each page pop up when you hover the mouse over the tabs. It's a super fast way to scan through a set of open tabs. Tab browsing addicts will love it.

Happy browsing, Buffalo!
