About this extension

Enhances the browser's default image viewer

Read the publisher’s full description

Enhanced Image Viewer ===================== Enhances the browser's default image viewer with: - more scaling modes (configurable in the preferences - click toolbar button) to cycle through when left-clicking - easy rotation (in 90° steps) using `l` and `r` for left and right rotation respectively - scaling mode and rotation can be remembered so they are applied when opening other images - configurable background color (not currently working when opening the options panel using the toolbar button due to a bug in Firefox: <a rel="nofollow" href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/c9e8a0a8176c457c5398233cc38912de23e22081cc103f49d287180f143bd722/https%3A//bugzilla.mozilla.org/show_bug.cgi%3Fid=1378527">https://bugzilla.mozilla.org/show_bug.cgi?id=1378527</a> but it does work if you go to the extension page using ctrl-shift-a) - image information and information about scaling mode and rotation are briefly shown when opening an image and can be toggled by pressing `i` Default browser zoom (ctrl-scroll/ctrl-plus/ctrl-minus) can still be used, but probably only works as expected in natural size scaling mode. If the chosen scaling mode is fitting the image to width or height, zooming does not change the image size.
