Tor Browser in Whonix blocks JavaScript (only when started for the first time) and in DispVMs
There is a long standing issue with Tor Browser that I reported to Whonix, but they say that it is an upstream issue.
There appears to be a race condition when Tor Browser starts for the first time NoScript is most of the times (8/10) blocking all scripts.
Since I run Tor Browser in so called "disposable VMs" (Qubes OS) where every Tor Browser start is as if it would start for the first time - this is a rather annoying issue.
To work around that I have to go to the NoScript settings after every Tor Browser start and disable restrictions, with the latest Tor Browser version this has become more painful since the NoScript button is no longer displayed directly in the Browser bar.
