I need to change the Font and page back to original Default settings. The writing is overlapping on most pages.
I changed the Font and page size to larger size for easier reading. Now the writing on most pages is covering other writing. I would like to know how to reset everything back to the original settings.

Reset the page zoom on pages that cause problems: View > Zoom > Reset (Ctrl+0 (zero); Cmd+0 on Mac)
See http://kb.mozillazine.org/Zoom_text_of_web_pages
You can see the defaults in a screenshot in this KB article: Some text shows up bold after upgrade
If you increased the minimum font size then try the default setting 'none' as a high value can cause issues like you described.
- Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)
- Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"

If you need to increase (or decrease) the font size on websites then look at NoSquint or Default FullZoom Level.
