Mozilla has made beta 2 of Firefox 3.6 available. If you are already running beta 1, you can use Help->Check for Updates to get the latest version.

Running the release through the Sunspider JavaScript performance benchmarks shows that performance is virtually unchanged from beta 1, but according to Mozilla, this version fixes around 190 bugs so it is definitely worth downloading (although I have to say that I have been running beta 1 on both Windows and Mac machines for a week or so and have had no issues so far).

Are you running Firefox 3.6? Let us know what you think of it below.

With the new beta of Firefox 3.6, new tab previewing functionality has been made available in Firefox — you can preview tabs using the “List all tabs” button, and you can see a preview when using Ctrl-Tab to switch between tabs.

These two new features are not enabled by default, so you’ll need to go to the about:config page and toggle “browser.allTabs.previews” and “browser.ctrlTab.previews” to “true” (either right-click on the entry and hit “Toggle”, or just double-click the entry).

I made a quick screencast showing how to enable tab previews and how it works:
