@baturkacamak I created a simply script for getting images from posts.
Script is not complicated. it's simply. Is the same like you adding it for main window on browser.
How you see, it's simple script. Generally extension like Darkreader(from chrome store) or others extensions, also working on sidebar instagram. Whatsapp and Messenger only doesn't work. But 😃 . Sometimes messenger is black, which means, that darkreader work on messenger (he manages to break through). But I repeat. Only occasionally when browser (system) is loaded.
Recently I really thought the tamper was working in the sidebar, and that was just the "bug" I wrote about. 😁
PS: Twitter also works.
Greetings.
