was working awesome for years. now, not working at all. the code gets saved - then becomes blank. one star, only because. . . it does not work at all. hopefully, it is worth it to the dev to keep this extension going. was such a helpful tool!
Not working on the Facebook
EXTREMELY un-intuitive UI, tiny "active" button you need to click that is not obvious at all. Also just doesn't work, can't even do something simply like change the background color. A simply 2 minute YouTube tutorial would be nice, but of course that would make things too easy right?
it does not work. I installed it and use it in a wordpress page and it was saying I was in about: page.
какие-то ужасные цвета панели, для красноглазиков похоже. В дополнении нет смысла так как уже давно есть tanpermonkey
The UI is awkward, but the functionality is exactly what I needed
Doesn't work on content within iFrames embedded in the page
Good tool, thanks The only thing missing if to match partial url, something like http://www.mysite.com/*
Not work its still off Error handling response: Error: Failed to execute 'createElement' on 'Document': The tag name provided ('page-manipulator-Template Artikel Blog') is not a valid name. at manipulate (chrome-extension://mdhellggnoabbnnchkeniomkpghbekko/content.js:351:45) at load_data_from_storage_and_manipulate (chrome-extension://mdhellggnoabbnnchkeniomkpghbekko/content.js:100:13) at chrome-extension://mdhellggnoabbnnchkeniomkpghbekko/content.js:175:13 at check_for_js_file (chrome-extension://mdhellggnoabbnnchkeniomkpghbekko/content.js:162:13) at chrome-extension://mdhellggnoabbnnchkeniomkpghbekko/content.js:168:9
