While typing in macOS Tahoe Safari, when I touch the space bar between words, Safari will open a video or will split screen on me. This is driving me crazy and I can't find the "switch" to stop this! I can't stand Tahoe!
Seems odd
Quit Safari and relaunch it holding the Shift key down and compare your results...
verify your software is up to date—
