[tor-qa] Tor Browser 9.0.7 is ready for testing

[Matthew Finkel]

Hello!

This list has been quiet for some time. We are happy to announce the
first Tor Browser 9.0.7 release candidate for wider testing. Packages
can be found at

https://people.torproject.org/~sysrqb/builds/9.0.7-build1/

Tor Browser 9.0.7 contains updates to a number of its components. Above
all, it includes Tor 0.4.2.7 which contains important security fixes. In
addition, on the Safest security level, javascript is now disabled for
the entire browser. Along with NoScript 11.0.19, this mitigates a bug in
Firefox that allowed Javascript execution on Safest. Javascript may be
enabled while using the Safest security level by enabling the
`javascript.enabled` preference in `about:config` and then modifying
NoScript's settings, as usual.

The full changelog since Tor Browser 9.0.6 is:

   * Bump NoScript to 11.0.19
