I use an external torrent app LibreTorrent. When I click on magnet links, FF133 faithfully opens the external app handler. However when I tap the OK button FF very often ignores my tapping. I can hit several times with no effect. I can see a quick circle showing as I tap, so the tap is generating an event, but FF does not react to it. This happens in normal and private mode. Sometimes after a couple or perhaps a dozen or more taps, the OK event has an effect and the external app launches fine. A very curiously I accidentally noticed that if I tap or swipe the text also showing on the dialog box before tapping OK, the first tap on OK always works! 100% reliable. Something is fishy with event handling. Repro: FF133 + current LibreTorrent client, then tap of first magnet link at https://webtorrent.io/free-torrents
