Maybe try to make some kind of cover to avoid touching the pad.

You can set mousewheel.with*.action prefs like the mousewheel.withcontrol.action pref (on Mac mousewheel.with_meta.action) prefs to 1 on the about:config page to avoid zooming if the Ctrl/Command key is pressed.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Maybe a support forum for that brand laptop will have some ideas, as that doesn't sound like strictly an issue with Firefox alone.

i try to keep my thumb palms off the mouse pad when i am typing but every now and then my screen resizes larger or smaller until i take my left palm off the keyboard base its only when my left palm is resting on the base next to the touch pad. i type pretty fast so it gets annoying and yes it also jumps screens or reverts back to previous message and i have to choose ctrl z to undo and get back to my message i was typing... it also switches tabs on me as well... not sure why my palm being on the left of the keypad on the base should effect anything but it does after a while. and i have to stop what i am doing...and go to the firefox menu and change the screen size back down to 100% sometimes it goes up to 200-300 other times it goes down to 70-80% i find it annoying i i wish there was a way to turn off the screen resize in the setup panel. if its just left to be 100% i am happy with that... i don't need it to be bigger or smaller... there should be a way to LOCK it down... i understand that there are people out there with eye problems and needs to have the screen size increase using the + or - but there should be a lock so it just stays no matter what is happening on my keypad or touch pad or base of the pad... that screen size will not increase or decrease. unless i turn off the lock... perhaps this is something they can implement in the next version or do a quick update of the browser

ok thanks that does make more sense with the laptop company thanks
