I am running AuroraFox 20.0a1 in my Power Mac G4 1.25 GZ Mirror door 2003 running on mac os x 10.5.8. I tested it and find my AuroraFox has secure connection not all websites. Example on this website This website need secure connection. When put this website in safari 5.0.6 and roccat 8.5 and AuroroFox has failed too connected and seaMonkey will take too connect to website but when I put in Tenfourfox will connected. I Tested all these browser too. But Safari 5.0.6 do not has secure connection on all sites. And Roccat 8.5 has not secure connection and will not connected to home page and failed error secure connection. But Sea Monkey 2.2.6 has secure connection not all websites. But TenFourfox Feature Parity Release 16 (SPR 1) has secure connection. Not all Browser has secure connection. You have test all browser and find which has secure connection which don't. At this time TenFourfox is only browser has been updated but Roccat not updated and last update was in 2018.

Incidentally, the main branch of Firefox was still supporting Snow Leopard as late as June 2017 - when support for the 45.x ESR branch was retired.

I've been using that build for some time now when I use the OS, and still works decently well as a browser, even with full HD playback from YouTube. (though I am using a 2008 Mac Pro with a Radeon 5870 so it helps)

I feel like once Intel settles in, we're probably going to start finding the last versions of software for Snow Leopard both due to Rosetta and the lack of official 32-bit Intel machine support on 10.7+.

Effectively a "TenFiveFox" when it was active.

Actively supported versions of FireFox for earlier Intel Mac OS's (based on TenFourFox) here:

TenFourFox FPR2 Intel

Intel 32-bits version (x86) for Mac OS X 10.4 Tiger: — TenFourFox

Intel 32-bits version (x86) for Mac OS X 10.5 Leopard: — TenFiveFox

Intel 32-bits and 64-bits version (x86+x64) for Mac OS X 10.6 Snow Leopard, 10.7 Lion and 10.8 Mountain Lion: — TenSixFox

32-bits versions requires a Intel Core CPU or later. 64-bits versions requires a Intel Core 2 CPU or later. 200 MiB of hard disk space is required and at least 512 MiB of RAM (1 GiB recommended).

The three version released here all have FFmpeg support enabled.

I've been using the Intel builds of TenFourFox for Intel Tiger and TenSixFox on Snow Leopard for several months now. Both work well.
