You had it right the first time earthlng. Eg Start commits for 55-beta date shown is 9-July. 55-alpha release is dated 18-Aug and we drop the "-beta" part (look inside the release downloads). Start commits for 56-beta date shown is 12-Sept. 56-alpha release is dated 2-Oct and we drop the "-beta" part. And because you created the 57-alpha release before you reversed the date+version, that too is all good.
Controls the visibility of the "Options>Privacy & Security>Site Data" section.
I'd prefer to remove this completely because it only adds to the confusion about all the different storage types.
This is just an extension for localStorage (2705) with 3 methods: estimate(), persist() and persisted(). A site can ask for permission (?) to persist data which when granted basically just means that "Storage will not be cleared except by explicit user action" whereas otherwise when not persisted "Storage may be cleared by the UA under storage pressure." - I don't see a problem with that.
We'll keep 2706 inactive for now but might remove it in a future commit.
Sorry, but AFAIK, with this enabled it clears web extension storage when clear "offsite website data" is checked on close or manually (which we do in the user.js). Note also that even with this enabled, the UI settings are disabled, and the data-on-disk calculation never finishes, so at this point, its a bit useless to enable it until we figure that out. Will be back in 7 days
