Words cannot express how awesome this plugin is (and has always been). I have been a TST user for many many years and it is the first extension I install on FF on any computer I use and is also the only extension for me that counts as a must have. It makes my browsing experience so much more richer and I am eternally grateful to the author for his continued hard work on this extensions (especially to port it to the latest FF which was no small undertaking).
