NOTE: If you come for the Thumbnail Expansion Rules feature, you can go directly to this post (Thumbnail Expansion Rules for Full Screen Image Viewer).
You can easily view images of a page in full screen with Full Screen Image Viewer extension. Just right-click on the Firefox browser and find the *Full Screen Image Viewer* item from the Context Menu. Or you can use the shortcut Shift-F11 (since version 1.3).
The Image Viewer can also open the image links on a web page or your local disk. You can use it as a local image viewing application.
After you click on the *Full Screen Image Viewer* menu on the Context Menu, the first image is shown. Below the image are the control buttons (except the last one):
Save the image. (Version 1.8+)
Toggle to see the image between its original size and full screen.
Jump to the first image.
Show the previous image.
Show the next image.
Jump to the last image.
Rotate the image -90°.
Rotate the image 90°.
Start the slide show. (version 1.7+)
Stop the slide show. (version 1.7+)
Toggle image filter. (See Image Filter section below.)

(Shown when the control bar is at the right side.) Move the control bar to the bottom. (Version 1.8+)
Close/Exit Image Viewer.
To the left of the control buttons is the information shows the current image number of the total image number.
Toggle show/hide the other control buttons. This button is at the top-left corner of the screen. It is only shown when you move your mouse to the top-left corner of the screen.
There could be many small icons on a web page. You usually don't want to view them in Image Viewer. If Image Viewer detects the image is small than the size you want to filter, it will not include the image in its showing list. The default showing size is 200px for both width and height. You can change it in the Options dialog.
You can also select whether to filter images in the Options dialog.
If the size of the image is unknown -- e.g. the image has not been loaded in the web page yet, or it is an image link -- the image will be included into the showing list. After it is loaded, its size is known and will not be included the next time if its size is too small.
Slide Show Interval
Since version 2.3, you can go to the Options dialog to change the interval to control the speed of the slide show.
Use black background
When check this option in the Options dialogue, you will be viewing the images on a whole black background. When this option is not selected, the background will be semi-transparent.
When check this option in the Options dialogue, the control buttons are shown at the bottom of the image viewer. When this option is not selected, the control buttons are hidden. Besides changing this option in the Options dialogue, you can also use the toggle button at the top-left corner of the image viewer to show or hide the control buttons.
Thumbnail Expansion Rules
This feature is added in version 2.0. It allows you to view the original images of a thumbnail on the web page.

Please read the post Thumbnail Expansion Rules for how to write the rules and the rules we provide.
