It still works as of 2013. I was doubtful to install this at first but I do recommend this script

Doesn't work on latest Firefox.

When I hit the install button on your script download 'overview' page, it takes me to a page with just the script written all over it line by line. Before it was a download file for greasemonkey, how do I install this. I am running 13.0.1 please let me know!

Any idea how to make it work again with mozilla 3.0.1?

This script saves me so much time and work.

Thank You

Yeah, that's what happened, facebook just changed the code and the button dissapeard :/

For some reason my select all button is not loading anymore! Facebook has changed their interface.... I am using Firefox 13.0 is that the reason its not working? please help me!

It has been working very well up until today. The script selects but then doesn't finished. It will select and unselect. Then I just get a beachball until I have to quit the browser. I'm using Firefox 12, not sure if there is an update or a fix but would be greatly appreciated.

...at least as of May 13,2012.

work pretty well with latest facebook and firefox version (april 2012)
