Mozilla has said that it will be issuing a fifth beta for Firefox 3.0 because of the number of unfixed bugs remaining in the browser.

The company is expected to "code freeze" it on March 18th, which means we should see a preview release of Firefox 3.0 in early April.

Beta 4 went into "code freeze" on February 26th, which means we’re very likely to see the fourth beta released publicly very soon.

After Beta 5, will we see another? You never know.

Microsoft also just recently unveiled the first beta of Internet Explorer 8. So, what we have here is ramp up to new versions of both major web browsers.
