[Mapsy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:56.0) Gecko/20100101 Firefox/56.0
Build ID: 20170926190823

Steps to reproduce:

Browse any website.
Zoom (you can use keyboard or clicks, it doesn't matter)
Zooming in stops at 300%
Go to about:config
Change the maximum percent for zoom.maxPercent to "800"
Restart Firefox
Still can't zoom past 300%


Actual results:

Zooming fails to zoom past 300%


Expected results:

Zooming should continue till I reach the % shown in about:config.

This is an accessiblity and usability issue.

Change the toolkit.zoomManager.zoomValues too.

Comment 2

Note: you also need to change toolkit.zoomManager.zoomValues per comment 1, e.g.:

.3,.5,.67,.8,.9,1,1.1,1.2,1.33,1.5,1.7,2,2.4,3,4,5,6,7,8

...and restart Firefox to have these changes take effect.
