The enabled/disabled setting does not work - although i have changed and saved the settings...
Everytime i restart FF it's back to initial.
Which means any mouse movement over a news article will trigger countless thumbnail enlargements...
i would prefer to enable the enlargement only with CTRL keypressed ... but this does not work!

Also, i could not figure out how the hot keys are supposed to work. (Pressing keys simply are passed to the original web-site and have no effect on a enlarged thumbnail...)

it would have been a great extension with all the features but it is (still) too buggy...
