Remove support for the alpha/hardened channels?
I'm not sure how I can stay ahead of major ESR transitions in such a way that doesn't result in people updating their bundle and not being able to launch Tor Browser in the sandbox.
Eg: 7.0a1 will be ESR52 based, and likely result in everything breaking. Going from 6.5 release to 7.0 release would be fine because I would have the entire 7.0 alpha period to work out bugs.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
