TenFourFox FPR9b3 available

TenFourFox Feature Parity Release 9 beta 3 is now available (downloads, hashes, release notes). This version has site-specific workarounds for Github's sudden hostility to TenFourFox (fixed using the same workaround we use for Imgur) and pages that use the new version of Cloudflare RocketLoader (by essentially defeating it). I also reduced idle time deferral for a couple rare crashes on the test systems that seemed to be from low memory and added a little tuneup for HTML5 parsing from Firefox 55.

Of the security patches that landed in this version is a specific one for an issue that affects 10.5, but not 10.4. It's more of an information leak than anything else and wouldn't seem to be very common, but I was able to exploit it on the test network, so now it's worked around. Our implementation is completely different from Mozilla's largely for performance reasons since we only have two operating system flavours to worry about.

Watch for the final to emerge this weekend sometime, for public release next Tuesday (not Monday because of the US Labor Day holiday).


  1. The TFF FPR9v3 beta corrected an endless page load on this news website Home page:

    Thank you!

    1. Looks like a RocketLoader site as well, so that's why.
