4Ktube Extension
A Safari toolbar shortcut opening the current page in a chosen other browser.
Useful when you routinely move a page from Safari to Chrome, Firefox or another app.
A single button, optional close-original behavior and a YouTube quality badge streamline the handoff.
Keep in mind: It does not add a video codec to Safari or guarantee higher quality on every device. The ad-skip shortcut depends on current site behavior and is not a general ad blocker.
