Firefox is now displaying my tabs in a smaller, paler font. It is very difficult to read. How do I make the tabs easier to read, namely larger and bolder?

You can look at this extension:

• https://addons.mozilla.org/firefox/addon/photon-colors/

You can also create your own theme:

• https://addons.mozilla.org/firefox/addon/firefox-color/
• https://color.firefox.com

Thank you for these suggestions.

I prefer not to develop a whole theme.

I just want to increase the font size on the tabs and make the tab fonts black or very bold so that I can read them easily, as I could before the most recent "upgrade".

How did you do that previously as that would usually require code in userChrome.css to style the Tab bar or modifying layout.css.devPixelsPerPx on the about:config page to apply a global zoom ?

Thanks for the follow up question, cor-el,

I never had to change the font in tab labels before this latest upgrade. I could read the tab labels quite easily in the default format. Now the default format is a smaller and paler font (grey instead of black).

I don't code. I have been hoping that I could just find a menu somewhere that allows me to change just the text in the tab heading, more or less as I would do in Microsoft Word when I want to change a font.

I have this question also.

I am trying to fix it myself through Control Panel - Fonts
