Mozilla has spun out a post-beta, pre-release candidate version of Firefox 3.5.

The build of the browser was released yesterday. Mozilla only wants developers to test run the inbetweeny version, dubbed Firefox 3.5 Preview.

It’s advising everyone else to sit tight until the official release of the browser.

The open source outfit had planned to push the release candidate build of Firefox 3.5 out the door last week.

But Mozilla, which isn’t exactly immune to delays, missed that deadline and instead can, as of Monday, only offer a preview build of the browser.

Mozilla was keen to insist that Firefox 3.5 is indeed “coming soon”. It added that it was hoping the release candidate would land within the next one to two weeks.

“While this [preview] release has not yet completed the testing required to be declared a release candidate, it is considered stable for daily browsing use and we appreciate your assistance in helping us test and evaluate this preview release,” said Mike Beltzner yesterday. ®
