Hi, I just installed Kubuntu 20.10 on an USB flash drive. System's font size is fine. But, the font size of Firefox's interface is so tiny. The font size of webpages are fine and I am able to change it in the Preferences.

When I searched on Google, the other users having same problem recommended to add a 'userChrome.css' file with some code that specify the font size to the Firefox's folder. Then, I came to know that Mozilla has disabled the userChrome.css in recent Firefox versions. I also changed a setting in about:config to make the Firefox accept the userChrome.css. But, the font size is not changing yet.

Please, guide me how to change the font size of Firefox's interface. Thanks in advance :)

Hi, I found the solution from Ask Ubuntu website. I changed 'Force Font DPI' to 230 in Settings > Fonts. The default value was 96. Now, the fonts of Firefox's Menu bar and Tabs are bigger.
