Hi, This patch updates Tor Browser to version 10.0. I've done some minor testing and everything seems to working. One thing that will need attention in the future is the cleaning of the profile dir, as the upgrade process does not touch it and so older configs and extensions remain on user profile. Main changes from the previous version are: - added a new phase to merge pluggable transports preferences into default tor-browser preferences before configuring the build instead of applying them on user preferences at runtime. - https-everywhere is now a builtin extension and requires further steps to be available at the right place. - defined %tbb-build in order to further differentiate tor-browser and tor-browser-build version tags.
