Pier Angelo Vendrame pushed to branch tor-browser-128.2.0esr-14.0-1 at The Tor Project / Applications / Tor Browser Commits: af856ef0 by Pier Angelo Vendrame at 2024-09-02T10:11:08+02:00 fixup! Bug 4234: Use the Firefox Update Process for Base Browser. Bug 42747: Discard unsupported updates earlier. Firefox's updater has a function to select updates, which checks mainly the version number. Therefore, a more recent update that is unsupported will be chosen over a compatible one. We patch this to be able to provide an alternative update path to Windows 7. - - - - - aa6ba139 by Pier Angelo Vendrame at 2024-09-02T10:11:12+02:00 fixup!
