Image Zoom by Jason Adams

Rated 4 out of 5 stars 307 reviews

219,990 users

Adds zoom and rotation functionality for images...
Collector's Note Actually it should be called "Image zoom and rotate". You don't have to leave the page to zoom an image like with some other addons. It creates two context menu entries with submenus that allow you to zoom or rotate an image by a specified amount. The context manu entries show up only when you right click on an image. Smart!

MinimizeToTray revived by Nils Maier

Minimizes windows into the system tray.
Collector's Note Minimises Firefox to tray instead of closing it.
