How do I get rid of white flash when opening new tabs in Firefox 64?

Posted

I am using Firefox 64 on Mac OS X Mojave. I am using the default dark theme, and whenever I try to open a new tab or window, the browser window flashes white for a fraction of a second. I would like to get rid of this seeing that it is annoying and negates the benefit of using a dark theme. I have tried every solution online involving userChrome/userContent but no solutions have worked (except using a private window). Please advise, thank you.

Before any page loads, there is an empty browser frame. A rule in userChrome.css can color in the frame, so that is a necessary part of the project. What isn't working on yours? Could you temporarily use a blue background instead of black to see whether that ever appears?

This is a comprehensive approach: https://github.com/overdodactyl/ShadowFox

Do any rules in your userChrome.css and userContent.css files seem to be in effect? If Firefox seems to be ignoring the files, please review the steps in the following article to make sure your chrome folder is properly situated: https://www.userchrome.org/how-create-userchrome-css.html

Also, when you say the default dark theme, do you mean the Default theme, or the Dark theme? Built-in themes in Firefox - alternative to complete themes

Thanks for the ShadowFox link, that is the fix I was looking for.

I was using the dark theme, and I did manage to change the display using userChrome.css. I'm not entirely sure why my edits weren't effective in solving this particular issue.
