I thought there was something wrong with my mouse or software.
So I opened up Chrome and firefox, browsed through multiple pages and pressed the button to go to the previous page and it works as intended. I press once, the page goes back once. I press twice repeatedly, goes back two pages.
Only when I click my 'back' button once on my mouse on Opera GX, the browser brings me back two pages instead of one.
Any clue on why this is happening?
