Mozilla has released the twelfth and final Firefox 4 beta.

"We are in the final stages of the Firefox 4 Beta cycle," reads a blog post from the open source outfit. "The team has fixed more than 7,000 bugs since the first beta release."

On Thursday, Mozilla release manager Christian Legnitto confirmed that number 12 would be the last beta we see before a release candidate. In addition to rolling out various bug fixes, the new beta "delivers improved performance and responsiveness when watching videos on your favorite video websites". That means better Flash performance.

The release notes also say that the beta plays nicer with plugins when hardware acceleration is enabled, and if you hover over hyperlinks, the URL now appears at the bottom of the browser window rather than over the location bar. Hopefully, your eternal happiness isn't tied to the location bar hover.

You can download the beta here. As always, it's available for Linux, Mac, and Windows. In that order. ®
