Thanks man appreciate the port, was going to do it myself but figured someone had already done it.

does not work anymore

only seems to work on word docs, does nothing in spreadsheets

Works like a charm, would really benefit from having the cursor visible when using the "grey mode"

does absolutely nothing

Thank you.

This would benefit from configuration/options to choose the background even darker or black.

FYI This applies to G. Docs editing page only. It doesn't apply to the page which lists your G. Docs.

Update 4 years later: Not working for current G. Docs.

Works okay (sometimes) but I've been having an issue with Firefox Version 95.0.2 where instead of the secondary toggle turning the page grey with white text, it just turns the border (black from the top switch) grey and turns the cursor white. It was working right for a few weeks when I first installed it, but I can't seem to make it work right now. Same issue on my work PC.

Works like a charm, thanks!
One little thing, comments in Google Docs are still white, could this maybe be fixed at some point?

It literally just makes the document border black. The actual document, and all menus and such are still their normal color. Actually makes it much worse.

Does absolutely NOTHING in Firefox 94.0.2 (64-bit)

It does what it says it does, although it has some funky working switches which you have to turn on and off again to make them work correctly. Thank you for relaxing my eyes at night.

It removes the ability to see spelling and grammar mistakes underlined on words

I'm only rating 4 stars instead of 5 due of me having issues seeing where my cursor is when i activate both options on google docs. (to have grey mode), other then that. This is great! https://imgur.com/a/Q5logug

Its really good! The only problem is that page is still white while everything else is dark. Other than that it works perfectly

Works exactly as promised. No longer is working in Google Docs like staring into a spotlight.

Currently it blacks out the Styles menu which can make formatting your document a bit difficult.

Fix the black text please

It changes the background of the Google docs from eyeball destroying white to a pleasant dark grey or black and doesn't mess up the overall theme of my browser or any other websites (unlike other add ons I've tried), nothing too fancy, doesn't have a hundred unnecessary features that cause crashes or slowing down, simply does what it's supposed to do: spares my eyes from the default google docs background white, nothing more, nothing less. Exactly what I needed, thank you.

Works well but really needs options to be able to set the colours. At the moment you can have it in any colour, as long as it's black :)

Partially works; document editing can be fully dark if you change your page color for the document. Document list is still white, with the exception of the hamburger menu.
