Although we're not yet hosting Firefox 3.5 RC1 (it should be released publicly at the end of June or July) on v3.co.uk/downloads, we're busy testing it for compatibility across our systems, including our internal CMS. So far, so good.

The first impression is that it's far faster than the older Firefox 3.0.x, which is the current public release version. It's clear to see a big difference if you use 3.5 for a few hours and then revert back to the current 3.0.11 release. There are also big improvements to the support for the latest web technologies, including HTML5, new CSS properties and much more. There's a private browsing mode which means that the sites you visit will not be recorded or stored on your drive, keeping your privacy safe.

Be aware that some themes, add-ons and extensions may not yet work with the latest Firefox 3.5 RC1 and some may need to be updated manually using a test version of the add-on from the developer's website.
