The Firefox Configuration Guide for Privacy Freaks and Performance Buffs was heavily updated again. The biggest change was the re-introduction of uMatrix in addition to uBlock Origin. I dropped the former quite a while back thinking that uBO could handle everything sufficiently enough, but that’s not the case. Much other information was overhauled as well.
The Firefox Tweaks and Fixes and Styles and Things article was also updated again. I added a couple things including a warning about using the sidebar CSS. If you happen to be using that code, or any style that auto-opens/closes the sidebar, please read the warning.
