Constrain or set the maximum font size limit of text in web pages

[thefirefox]

Hello,

I am a Firefox user. Recently I've been noticing a trend of web pages using font sizes that are way too large to be readable easily (for e.g. like headings and other titles).

How can I set the Maximum Font Size limit in pixels for the text in webpages? If the font size is set higher than the limit, it is clamped to the maximum. This seems like an essential feature that is missing. There's already a 'minimum font size' setting, but I'm looking for the opposite.

Can you suggest solutions?
