Before an update, a possible alternative:
Simple Translate par sienori (Firefox Adddon)
Very simple and with interesting options (but not shortcuts yet...)
The script stopped working, at least with chrome+tampermonkey. You can fix it, by uncommenting the 621-st line (the furry number hehe), that is, replacing
//TKK='427882.1140482906'
with
TKK='427882.1140482906'
. With tampermonkey it's easy and intuitive to modify an already installed script.
Seems the script stop working.
Here by example ....
Any update ?
