As with the last Firefox 3.5 (formerly known as Firefox 3.1) beta, there's improvements to the performance, pages render faster, pages with JavaScript code run much faster, with the new Tracemonkey engine. Although this Firefox version, listed in the update as "Firefox 3.5b99" carries the new title "Firefox 3.5 Preview."

Firefox 3.5 Preview starts up much faster, and as Mozilla says, it seems ten times faster than Firefox 2 and twice as fast as Firefox 3.0. Mozilla's marketing campaign for Firefox 3.5 is inviting Firefox fans to upload videos of them doing something “very fast.”

Firefox 3.5 Preview still scores a 93/100 on the Acid 3 test.



As before we think Firefox 3.5 Preview is just about ready for public use as a stable Firefox 3.0 update. There is still the remaining problem of the "Full Screen" option in Adobe Flash that crashes Firefox 3.5. whether this is Firefox or Adobe, we don't know, but it's a remaining problem.
