Thanks for the review! Yes, this is a known issue on macOS and Linux, and unfortunately there is no fix for it yet. Moving the swipe to the left or middle button isn't an option either, since browsers already use those drags and clicks to open links in new tabs and windows.

As a workaround, open the extension's menu -> SETTINGS -> Manual Ignore and, at the bottom, switch the Ignore and Already played bindings to a click, for example Shift + Left-Click or Alt + Left-Click. To un-ignore a single game, you don't need the gesture either. Just click the IGNORED badge
