I use Linux Mint with MATE.
The touchpad of my laptop displays occasional erratic behavior that I attribute to my touches triggering some "special functions".
This manifests while browsing with firefox when the browser suddenly moves forward or back or loads some previous site seemingly at random. Other occurrences are random insertions when I edit a file.
I do not want to use any of these special functions and I would like to disable these special functions. The touchpad itself I want to keep using when I do not have mouse. However, I have not found any of the according options. Can you give me an advise?
