After changing the colors of websites and text I cannot go back to the original settings using the options under settings.

I changed the colors of text and webpages. However, I cannot go back to the original settings under Options. The Options page shows up in the changed color with no text so I can't go back to the original color settings. I have uninstalled and reinstalled to no avail. I use Windows 10, 64-bit with Google Chrome browser.

Sounds that you have set text color and background color to the same color, so you do no longer can see the text.

What color do you see?

Did you set the text color to white or to black?

Can you open the about:config page via the location bar? You may have to highlight (select text to see what you have typed).

You can paste this in the search bar on the about:config page.

  • browser.display.foreground_color

That should give one line that you may or may not see, but you can click the first line on the about:config page. You can reset user set (bold) pref(s) on the about:config page via the right-click context menu to the default value.

Double-click this line and enter #000 and press the Enter key to set this color for the text color.

Repeat this for this pref and paste this in the search bar:

  • browser.display.background_color

Double-click this line and enter #FFF and press the Enter key to set this color for the background.


If you aren't able to do the above then create a text file in the Firefox profile folder named user.js and paste this code in the user.js file. user_pref("browser.display.foreground_color", "#000000"); user_pref("browser.display.background_color", "#FFFFFF");

The profile folder is in a hidden location in "AppData\Roaming" and has a random name xxxxxxxx.default.

I didn't set the text to the same color as the background. The text color is black and the background is red. Some text shows but not all of it so I cannot go back to the original.

If the colors are fine then you should see the text unless there is actually another problem like with the font that is used.

You can try to reset the browser.display prefs that appear user set (bold) via the right-click context menu to the default value.


You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
