How do I Increase Size
I want to increase the size of everything in Firefox, especially the type (font) size. I know how to increase or decrease the font size within documents, etc but not within Firefox as a whole
This happened
Every time Firefox opened
== always

If you mean the font size for every webpage, then try this addon
