Hi! I know this is not very descriptive probably, so sorry for that, but a relative of mine has a new laptop with Windows 11 and often, after a while using it with normality it starts to open every link on a new window, as if shift was clicked on. Don't know if you can activate a similar function to shift by accident or something, but it has happened a couple of times to him since he bought this laptop. I couldn't replicate this myself yet but since I have found some similar posts about Windows 11 and Firefox tabs I was wondering it this does ring a bell to you. Thanks!
