Zoom-in on webpages not remaining after re-start

I have the latest Firefox for Windows on my computer. The default font sizes when opening the browser were too large, so I zoomed in twice (using 'view', then 'zoom-in'). It worked for the session. But once I close and re-open the browser, that change didn't 'stick'. I have to zoom-in every time I re-start Firefox. Tried just about everything that I can think of, but nothing seems to work (even changing the 'tools', 'options', 'fonts and colors'...because that messed up some websites that I use).

Any advice would be most appreciated.

Chosen solution

In case you use "Clear history when Firefox closes" or otherwise clear history:

  • do not clear the Site Preferences

Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
