Meanwhile I'm enjoying the ability to multi-select tabs and close, move
send to a device and other actions, content blocking, block autoplay of
sound on websites, security updates and more using Firefox Nightly 65.0a1.
Not too fond of the new look of Add-ons Manager, but how often does one
go there. It is nice to have links to Add-ons Support and Preferences in
the page. Preferences has a link to Extensions & Themes and Nightly Support.
