Solved Websites text differ in size

Just switched to my main monitor and am having major problems with websites. Seem every website I go to I have to manually zoom to make the text bigger so I can read. Isn't there a setting to make all the websites the same? Oh, I'm using Firefox if that makes a difference.

That helped out a lot. Need to familiarize myself with it some more but things are already looking better. Thanks!

Yes, neat little add-on. Keep fixed text size anywhere you surf.
