When I change my OS theme (Linux Mint) to a dark one, the textbox in GOG chat is grey text on grey background and difficult to see. See attachment.

Could anyone help me change it using a custom style? This is what I tried, but it doesn't work. Sorry I'm a complete newb when it comes to this.

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("www.gog.com") {

.chat-view__send-message chat-send-message {
color: black !important;
}
}


Thanks.

Try domain chat.gog.com

Edit: Perhaps I should explain. ;) The whole chat is in an iframe with chat.gog.com as a source

Sorry, this didn't work. This did. Thank you!

Unfortunately, a few other sites have this problem too in some of their input boxes. And on top of that a few programs too (Libre Office) look ugly. Some programs have dark themes too in settings (I imaging Libre Office does too), but it's a pain having to change all of them. Think I'll stick with the light themes.

Because I'm a numpty and I've fixated on the domain - which was part of the problem - and forgot to check the rest. My bad. ;)

Yes, if I use www.gog.com with clarry's solution it doesn't work.

chat.gog.com or gog.com does.
