very good. download hd to 4k video

Dadan·21 Nov 2025

Handy extension, but this should be configured to only run on Instagram. This has a nasty side effect of adding a CSS style for "alert" that sets the opacity to 0 (not visible) which affects elements on other sites.

Doesn't work on windows. No download button shows,
