I’m running Big Sur 11.6, with Safari version 15.0 (16612.1.29.41.4, 16612). I spend much of my day filling in web forms for my day job. Safari is, with increasing frequency, randomly opening or re-opening tabs. This happens on any inactive browser window that is open, as well as open browser windows that I am actively working in. This is annoying at best and totally infuriating at worst, as at times I have put in 15-20 minutes of work into a web form and it randomly flips to my home screen and all of the data I have put in is lost. The “back” button remains inactive, it doesn’t even open a new tab, it just replaces whatever I am in the middle of. Makes me want to throw my computer. Is this a known bug? Is there a fix for this? Will it stop happening if I install the latest beta of Monterey? Should I just wait 3 days till it is officially released?
Update: I just found that the tab reset is not a reset at all-- Safari is opening a new tab and stealing focus, however the tab I was previously working in then does not show up in the tab bar. I can access it with “command-]” but the tab itself is invisible. Also does nothing if I click where the next tab should be, the actual UI element is just not showing up.
