Grayscale Tool Extension

Originally intended for web designers who might want to test the contrast of their content by changing to grayscale, but this extension can really be used by anyone who for some reason want to remove the colors of a web page.

The grayscale persists between page loads, and the key shortcut to activate can be customized in the options.

Old “Laag” Starchy (ID: 000000529bd865a0) Voted 4 ★ - Updated 09/14/2023 Works well, I would prefer it to store on/off state per tab since I'll only need it for one or two tabs at a time but for my usage I only activate it briefly now and then so I don't need to worry much about opening/refreshing other tabs while its on. I'm using Alt+G as the shortcut as I already use Shift+G for something else.

Zach and Jadyn Stewart (ID: 0000004629f719ba) Voted 4 ★ - Updated 02/22/2021 The short cut didn't work at first but I had to refresh the tabs I had open before I installed the extension before the short cut started working.

Blake Nelson (ID: 000000e645954289) Voted 5 ★ - Updated 08/13/2019 Works. If you're having issues, it's because you're trying to use it on a web page you had open before installing the extension. Try refreshing that page and then using the hotkey. :)
