Moreover, we fixed sandbox incompatibilities for 64bit Windows Vista users [5] and amended the NoScript whitelist [6], which unbreaks extension panels on higher security levels.

Note: We did not include the latest HTTPS Everywhere release in Tor Browser 7.5.1 as we need to first test some changes in its new build system [7] in an alpha release to make sure we still can build everything reproducibly. We expect to have this fixed in the next stable release, though. Sorry for any inconvenience.
