Zoom Level Resetting in Firefox

[gnuarm]

This probably is not a EEVblog problem, but I just rebooted Firefox and now it seems to have lost short term memory for the zoom setting on some web sites and not others.  I have to zoom in to read the text, presently I'm at 150% zoom.  Every time I click to another page within the site the zoom setting resets to 100%.  In fact, I only need to switch tabs and it resets the zoom.  Restarting Firefox a couple more times does not fix the issue.

A google search didn't turn up anything... or actually far too much.  There are tons of issues with the zoom setting going back for years.  None that I found actually have these symptoms.  Mostly they were more about new tabs, so the default setting in the options. 

I guess I can try rebooting Firefox one more time.

You could set the default zoom level to 150.
Tools-->Options-->General-->Zoom

(Ctrl) + (+) = zoom in
(Ctrl) + (-)  = zoom out
(Ctrl) + (0)  = zoom reset (that’s the numeric zero key)

Check in about:config if you have privacy.resistFingerprinting enabled. It prevents zoom persistence because that would provide a strong browser fingerprint.

Don't know what changed, but another restart and it is working correctly again.   

I'm just glad.  Firefox does some things other browsers don't and this is a very useful tool for me.
