Mozilla Firefox 52 Beta 6 was released today, which mainly enhances the feature of sending tabs in the Sync synchronization function, so that the touch screen version can better support multi-process operation. The previously introduced security prompt if a password box appears on a non-HTTPS page has been deployed in version 52. At the same time, version 52 has reduced support for some old plug-ins and also optimized the download experience.
