Very useful extension. It will be even better if author add this action into right-button context menu.

Doesn't work on Mac.

Many thanks for creating an alternative to "Show the Image".
Unfortunately, it doesn't work yet as well as the original one, but I hope it will keep improving.
First of all, the original one lets clicking with the middle-mouse button to open the image in a new tab. It would be great to have the same feature.
Second, this extension doesn't work for all the pages. For some reason, in some pages where "Show the Image" worked, "Largest Image" doesn't seem to do anything. I don't know if it will be possible to improve it...
Thanks anyway. I wish you will keep working to finish tuning up the extension!

Simple and useful.

Would be great if it worked on Mac. "Cmd + ," is already taken by Firefox and there is no workaround. Being able to define a custom shortcut would make it 5 stars!

Superuseful, for me as an old user of show the image (which does not work on quantum) this is a very welcome extension that I've been looking for a long time.
Improvement suggestion: would it be possible to make the shortcuts user definable? On Mac I have to use cmd instead of ctrl for the shortcut to work and this collides with default firefox shortcut for opening preferences. Would be awesome to be able to select a different shortcut.

I tried to make a replacement for "Show the Image" myself, but couldn't get it to work. Then I found this gem and it works great. Thank you very much!

Great! All tabs to the right is a nice feature too. It would be nice to be able to trigger with a key-combination (the old "show the image" addon worked with ctrl-Q for the current tab; I guess ctrl-shift-q would work for 'tabs to the right'), but not sure if this is possible in the new Firefox. Anyhow, thanks very much, this is functionality I would have greatly missed in 57+ if not for your efforts!
