Resize from right too? Rated 4 out of 5 stars

This is one of my favourite add-ons, even though it's so simple :D

So, 2 things:
1) I usually have my browser over to the right of the screen, so it would be very useful to be able to choose in prefs whether the window resizes from left (as now) or right (i.e. move the left border)
2) Is a Fx 3 compatible version to be released soon I'm currently on b5 but will be onto RC1 asap.
Thanks.

This review is for a previous version of the add-on (0.1.7).
