Rated 4 out of 5 stars

Very useful, but it's incompatible with 'Save File to' extension. I'll add the last star if you don't obligate me to choose between them... thank you

This review is for a previous version of the add-on (3.4.3.1-signed). 

Please contact me with a detailed description of your Firefox/SeaMonkey version and the problems occurring and I'll see what I can do. Technically, OD² can't be compatible with EVERYTHING.
