    Why isn’t Firefox already supporting border-radius without the -moz prefix, like Google Chrome 5, Safari 5, IE 9… ?

      See https://bugzilla.mozilla.org/show_bug.cgi?id=border-radius and specifically https://bugzilla.mozilla.org/show_bug.cgi?id=451134

      There’s a bug open to do that. It’s more than just renaming since there are some differences between our -moz-border-radius implementation and the new border-radius spec.

        Christopher,

        Thanks for your prompt reply. Will the fix get included in Firefox 4?

          From the page for bug #451134 (thanks WulfTheSaxon), I see that the fix will show up in a future beta — good to know. :)

    Firefox no-longer functions properly on Mac OS X 10.6.4 I can’t open tabs and use them, can’t access Preferences since it wont open when I click on it, I can’t do anything in it anymore. Firefox has failed me now since 4.0 Beta 3… When will these bugs be fixed in Firefox so it’ll run properly again? because at the moment I’m stuck using Chrome as my alternate browser untill Firefox bugs in Beta 4 are fixed. All functionality in Firefox 4.0 BETA 4 has made it an unusable browser, can’t browse, Open Preference Settings, can’t submit feedback about it, can’t access the Help Page, can’t do any thing!

    The FullScreen API proposed in the Roadmap Slide ( http://www.slideshare.net/beltzner/firefox-roadmap-2010-0510 ) will be released in the Fiefox 4?

    Did the experimental Audio API make it into this beta update?

    @Jerome Covington: Nearly, but was backed out again.

    @Collin Blerg! Any chance that it will make it into the final 4 release?

      @Jerome It will probably be in the beta5 (it’s in the nightlies)
