You like to be on the latest and greatest, right? Firefox beta for Android has been updated to v50, so that would qualify as both late and great, if you're a user of Firefox on your phone. It includes a new video playback component and (more importantly) simplified panels.
The changelog is pretty small for this one, with just two items.
- Simplified panels by combining “Recent Tabs” into “History” panel
- Support of HLS videos via player overlay
The change to the panels is actually more in-line with what Chrome desktop does. You simply open one panel, and you see recently open tabs and the full history together. The HLS video player addition relates to live streaming video over HTTP. It's probably not going to make an impact on your daily usage.
