With some perverse regularity, the font spontaneously changes to a size so small that it is barely discernible and every time the fix is different. Why is this happening? .....and it is apparent that it is happening to others as well.

It is happening to everyone that uses the add on Theme and Font changer. The author keeps placing an expiration date in his software. This thread seems to have a fix. https://support.mozilla.org/en-US/questions/1213044

Thank you....I was able to fix the problem by downloading your "no exp" file to my computer and then extract and install by using the "install add-on from file" from the add-on manager drop down menu.
