Good day I recieved an update of firefox today, since the update I am getting a grey preview tab whenever I glide my mouse pointer over an open tab. In my settings menu "tab preview" is unchecked but it still appears. I headed off to 'about:config' and set browser.tabs.tooltipPreview to false but to no revail. Is there any way I can disable this grey preview tab in firefox as I do not need it ? I have this in windows 10&11 both the same issue.
