I have a problem where there are overlapping texts on some webpages that are not resolved by adjusting font sizes,
Windows XP, Firefox current version
If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.
- Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)
Make sure that you allow websites to choose their fonts.
- Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"
It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text.
- Default FullZoom Level: https://addons.mozilla.org/firefox/addon/default-fullzoom-level/
- NoSquint: https://addons.mozilla.org/firefox/addon/nosquint/
My default settings do not offer "none". I did the web page font setting set to none. Thank you
