Works o.k. - actually the shortcut Ctrl+Shift+B will not work on Firefox / OSX so you cannot break and get back to page one...

Simple and effective addon, with its companion "Enhanced Image Viewer" by the same developer constitutes an almost perfect mode to have slide show with series of pictures opened in fullscreen mode and background of preferred color.
Thanks

Firefox Quantum 57.0.1

It does exactly that I was hoping it would do. Show a picture without the surrounding page and/or do the same with a number of picture links on that same page.

I was look through your extensions library and now I have three of them Installed, thanks!
I didn't know I needed this extension to cycle images on a page, but I will probably start using it daily.
One suggestion though, a checkbox in the option panel to open the image in a new tab so when I'm done looking at the pictures I can easily close the tab and be back at the "source page". Now I need to duplicate the tab, or click back like a million times to be back at start.

Thanks again!
