Appears to be working again as of 6/8/2026.
Currently doesn't work as of 2026 May 22nd
This worked fantastically for many years, but in the last couple of months it has stopped working. I hope the developers update it soon. 5 stars when it is working though! Update 9/11/2025 I just saw another user's comment (https://chromewebstore.google.com/reviews/940b832c-f73c-4680-8738-095abd80253b) and tried their suggestion of "clicking 'manage extension' and changing site access to allow the extension to run 'on click' instead of 'on all sites.'" By changing this setting, the extension now runs beautifully again. As such, I'm revising my rating to reflect this. Though I do wish this information had come from the publisher themself!
It works perfectly and I was able to use it in my designing process on Substack.
The only page I'm unable to get this to work on so far is the chrome web store. If you are having difficulty, I would suggest clicking "manage extension" and changing site access to allow the extension to run "on click" instead of "on all sites"
It doesn't work anymore. This was a great extension when it did work.
very broken.
This plugin does NOT work in "Pictures" and on the main page, BUT it works on YouTube and other sites. First, go to the site, Then turn on the plugin Данный плагин НЕ работает в "Картинках" и на главной странице, НО работает в ютюбе, ВК и на других сайтах. Сначала заходим на сайт, Затем включаем плагин
Don't know why ... it seemed to work one time, then stopped. Click it on, pick your filter, nothing happens. I've tried on every website I care about, and it doesn't work on any of them.
Doesn't work on any website
