September patch set for TenFourFox

102 is now the next Firefox Extended Support Release, so it's time for spring cleaning — if you're a resident of the Southern Hemisphere — in the TenFourFox repository. Besides refreshing the maintenance scripts to pull certificate, timezone and HSTS updates from this new source, I also implemented all the relevant security and stability patches from the last gasp of 91ESR (none likely to be exploitable on Power Macs without a direct attack, but many likely to crash them), added an Fx102 user agent choice to the TenFourFox preference pane, updated the ATSUI font blacklist (thanks to Chris T for the report) and updated zlib to 1.2.12, picking up multiple bug fixes and some modest performance improvements. This touches a lot of low-level stuff so updating will require a complete rebuild from scratch (instructions). Sorry about that, it's necessary!

If you're new to building your own copy of TenFourFox, this article from last year is still current with the process and what's out there for alternatives and assistance.
