XKit 6 Preview Release 1 is now available for Firefox Users!
Starting with this release, XKit becomes a “native” extension for Firefox, not a Greasemonkey userscript, eliminating the need to install it too in order to use XKit.
If you already have XKit 4.x or 5.x installed, you have to remove it or disable Greasemonkey before installing XKit 6 PR1.
If you have any questions, suggestions or problems, please feel free to send me an ask. Thanks for using (and test-driving) XKit!
