Review for Classic Password Editor by Zitronius
Rated 5 out of 5 stars
Great extension - works flawlessly with nearly all sites!
Off-topic: And a piffling review giving only one star just because one exotic configured site refuses to cooperate with Classic Password Editor is as sapid as the stench of a dog's rotten mess drifting from some godforsaken area.
