Hi everyone! Since last update (136?) when I open a page with a (Youtube) video in a new tab, the width of this tab is very small! Almost half my current tab. On Youtube.com but also on another random web page, with a (Youtube) video. (I don't have another example yet but does this have anything to do with a "media" on the page? Youtube or not?) I've had the width set to 152 for years... Also, when I play the video, the current tab is reduced. Pause: normal tab. Play: small tab. Pause: normal tab... I just completely reinstalled Firefox: still the same. What can I do, please?
