Just to be certain, two ways to set the default "global" minimum zoom level. (1) At default zoom addon option setting window, and (2) about:config > zoom.min Percent. Same end global result, correct?
If so how to maintain both settings. the About:config setting does not seem to stay put. Why Please? Thanks Jim
EDIT: With no reply to help me, I proceeded on my own.
I experimented and report to help others in need. The minimum zoom level set by about:config zoom.min Percent setting (of "30" for me) holds its own fine once the default zoom addon is disabled. But when this addon is enabled again, then the about:config zoom.min Percent setting drops back to its original "30" value.
Thus, this addon's options zoom setting does directly control the about:config zoom.min percent setting.
Enjoy all, Jim
EDIT2: Oh, and CTRL + 0 (zero) is a reset to the set default zoom level. Pretty handy gal !! Thanks
