Not working anymore since the 25th July update.
Edit: tested it on a different device and it works there.
Edit after 6 months: The problem was with the 'Press ("G") to block site(added to grants), Shift to allow site' setting. Most sites I visit were blacklisted.

Imagus formed a solid platform and was a great extension in itself, but since active development was stopped, the community had to step in, at first just to produce sieves, but then Imagus Mod was developed, with all the QoL improvements that the original sorely needed, plus the developer (especially as of recently) is really on it and very approachable. Thanks for keeping this going!

Many thanks to the mod author and all sieve authors.

I've been using the original Imagus for several years but the developer stopped updating it 3 years ago. The original add-on stopped working on Instagram at some point. This mod solves the problem perfectly!

Great improvements, coming from the original. Thanks for the great work!

So far seems to be working fine... Glad to hear developer enabled the issue tab so can report problems.
