User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:20.0) Gecko/20100101 Firefox/20.0 Build ID: 20130326150557 Steps to reproduce: I move the mouse wheel. Actual results: The browser font size often changes by mistake. Expected results: The font size should stay the same. My mousewheel button sends the meta modifier when depressed. I could be wrong, but it seems that meta + mousewheel seems to have been recently changed to change the font size (in addition to control). I don't see why this was changed, when control + mousewheel works fine. I have changed the preference mousewheel.with_meta.action to 0 to fix it, but maybe there could be a visible setting somewhere?
Oh, I want to point out that I realize I must be accidentally depressing the mouse button a bit when using the scroll wheel, but only with a recent firefox has this issue been encountered. And encountered all the time. also, I found these pages: http://rachelbythebay.com/w/2013/04/05/zoom/ http://night-ray.blogspot.com/2008/01/firefox-scroll-wheel-font-size-changer.html
Actually mousewheel.with_meta.action set to 3 causes zoom with meta button and mousewheel.with_meta.action to 0 to disable it; This is a Firefox feature. You can read https://support.mozilla.org/it/questions/955305 to view all the value for mousewheel.with_meta.action and change them according to your needs. Do you have problem with zoom setting mousewheel.with_meta.action to 0?
I set it to zero a few days ago and the problem was resolved (for me). My actual question is: why was meta added for zoom in addition to control? A lot of people have meta-click mapped to the middle mouse button to select individual items in a list, and I'm sure they're starting to encounter this problem, maybe not realizing what is happening. Thanks

Since you haven't problems I'll close this. > My actual question is: why was meta added for zoom in addition to control? Control + wheel is reserved by Mac OS; you can read here https://bugzilla.mozilla.org/show_bug.cgi?id=814303 and have an idea of the discussions that carried on this choice.
