When I start firefox, the font looks normal for a while. And then something changes. Every website I go to, after a few minutes of using firefox, has an almost scary looking font, very pointy and small. When I close firefox and restart it, it looks normal again, and then when I'm not paying attention, the font changes again, for every website. I need some help with this, it's creeping me out.

This happened

Every time Firefox opened

== I started noticing it a few days ago.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You can use "Disable all add-ons" on the Safe mode start window. You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
