MUCH NEEDED however... Rated 1 out of 5 stars
This is a much need addon and it's concept seems very sound however the growing pains of it are a bit much.
1) Database appears to be a bit too biased and from what I've read on USO it was actually errored for a while. A lot of scripts still aren't showing up... perhaps in time this will iron itself out.
2) Greasefire should give an option to open the scripts web page in the main window instead of building a sub-browser window... which leads to the next point.
3) Browser subwindow in this add-on completely ignores browser security... e.g. cookies, images, scripting, etc. Could easily be remedied by giving the user an option described in point 2.
Because of points 2 and 3, I can not recommend this script to anyone... I'm still of the opinion that once a few security concerns are addressed and the database retrieval method is fixed (and updated without too much bias [I know spammers like to hit USO a lot])...
...this could easily get a FIVE STAR rating!
