How can you disable zooming in Internet Explorer and Firefox?

The zooming features in both Internet Explorer 8 and Firefox really bother me. I use Ctrl + (TrackPad Click) to open new tabs and often my finger will graze the track pad which activates the zoom feature (Ctrl + mouse wheel basically). Then normally the tab, which was just opened, will be 1000% or 10%.

How can I disable this feature, I will never need it?

Solution 1:

Firefox

Enter about:config in the address bar. Now, look for zoom.maxPercent and zoom.minPercent and fix their values to 100.

Internet Explorer

For Internet Explorer, I think this is what you meant:

Go to menu Tools >> Internet Options >> Advanced and check that box.

Solution 2:

In Firefox, if you still want the option of zooming with ctrl-- and ctrl-=, you can go to about:config and set mousewheel.withcontrolkey.action to 0. This makes it so scrolling with the control key down does the same as scrolling without the control key.

I couldn't figure out how to disable the ctrl-scroll binding entirely.
