Bedømmelse: 3 ud af 5 stjerner

Installed it and tried to open a zip file. A pop up comes up asking whether I want to reveal it. I say yes, but then nothing happens...
I use firefow 20,0,1 Windows 7 from 2009

If the developer of this add-on makes true his promise to make an even more user friendly 'Unzip' & makes it possible to unzip really large files... Then I promise to develop 'Zip'.
I see a bright future with unlimited Zip and Unzip of countless files, big and small, all within Firefox. Highly recommended.

Merci but what do you mean by 'Then I promise to develop 'Zip''? Are you developer?
