If you have not tested Firefox 4 yet, give it a try!

Mozilla has released Firefox 3.6.6, an incremental update which tweaks the way the browser handles misbehaving plug-ins, giving Flash and other plug-ins 45 seconds to respond, or else get shut down.

Although Mozilla's Firefox 3.6 is still in beta, the CRN Test Center reviewers wanted to take a look at it because we measure the progress of a browser in development by doing a series of benchmark tests against each alpha, beta and final versions to determine whether there are performance improvements with each release. For instance, when we tested Firefox 3.6 Alpha 1, we were pretty impressed with the benchmark results.
