After failing to keep up with the original Firefox 4 release schedule due to “regressions and sources of instability,” Mozilla had to revise its initial estimates and push back the launch of the stable version to 2011. The open source outfit on Wednesday shipped Mozilla Firefox 4 Beta 8. The actual release of the latest beta comes nearly a month later than originally anticipated.
According to the release notes , the latest build boasts a vastly improved Firefox Sync setup experience across desktop and mobile devices; speed, compatibility and functionality enhancements to WebGL; and a much more polished Add-Ons Manager, which now updates extensions automatically. Furthermore, Mozilla has fixed more than 1,400 bugs.
