Mozilla has updated Firefox again, just one week after its last update. Available for Windows, Mac, and Linux, Firefox 3.0.10 fixes a stability problem that also behaved like a security breach. A critical regression error unintentionally introduced in v3.0.9 caused some users to suffer frequent crashes when using the HTML Validator add-on, subsequently linked to potentially compromised browser security.

Mozilla also introduced Firefox 3.5 beta 4 last night, said to be the last beta version before the major features it introduces reach the release candidate phase of testing.
