Mozilla on Wednesday released the Firefox 4 release candidate, the final update before the company formally unveils its next-generation browser.
Those who have been testing Firefox 4 will be automatically upgraded to the RC. Mozilla said it has fixed more than 8,000 bugs since the first beta release of Firefox 4, but encouraged RC users to test this latest release as well and provide feedback.
Mozilla executives expect the final Firefox 4 to be released later this month.
Mozilla has streamlined the user interface, collapsing the full menu bar into a small "Firefox" drop-down option on the top left. The tabs are front and center, with the URL and search bars underneath.
