hama compact mouse randomly right clicks

Get no script

 

hama compact mouse randomly right clicks

hello
i got a plain compact mouse from hama (hama am 5400)
but i noticed that i get randomly multiple and fast right clicks and some windows open up if that happens or the browser gets into "analyse java script" mode.
its like my mouse is randomly clicing for some seconds on its own

i know that behaviour from laptops. idk why, maybe because of touchpad sensitivity, heating stuff, sometimes there are ranom rightclicks i read.

but its an usb mouse, with 3 buttons (left, right and wheel). what could be the cause?

and if it helps: first time i plugged in the mouse to my usb port, it searched for drivers. but there was that windows sound, that normally comes, when something is plugged in and out many times in a row.
it felt like the computer had a hard time to even recognize the mouse.
but well, in the end it worked and it actually works well, except these random right clicks now and then.

does someone has knowledge bout this problem? could it be that my usb ports are not good anymore? my computer isnt actually the newest. its pretty old.
and on the computers back, some usb ports make me struggle. like.. taking long. some of them i dont even use anymore.

but the fromt usb, i used my old mouse with it too. never right click problems. but the left button got old so when i click, it sometimes doesnt recognize that click, or it makes a double click.

 

hama compact mouse randomly right clicks

im using firefox 58.0.2
well i didnt have many mouses so far.. as i said, the old one got left-click bug. it double clicks or never clicks sometimes (i confirm that this is because the mouse got damaged).
but random rightclicks without me even touching the right moue button never existed with my old mouse. its only the new one that behaves like this

i will try that. the problem is: i dont know when it will randomly right click again. it can take hours. or days.
