Mouse problem

Hello,

I've been having this issue lately where my mouse seems to be clicking things randomly.
Lets take for example youtube: I'm watching a video, skipping the borring part but then out of nowhere i get back to the video i watched before that.
Its getting also really annoying lately and i can't seem to fix it nor find it anywhere on how to fix it. And it mostly will happen on websites it wont even happen on video games or anything else.
Even tried to remove some extensions that where not even needed.
