I recommend trying Imagus mod.

Compared to the original Imagus, there is a serious improvement here - loading the current version of Sieves (rules, filters), while the outdated ones are installed along with the original, which misleads users.

There is also FULL support for hotkeys - while in the original some of them are blocked. It is convenient to save Settings. And finally there is an extension icon on the panel. By clicking on the icon, you can quickly disable/enable the Imagus mod, SHIFT+CLICK - opens the Settings.

File saving has also been seriously improved (the Imagus on some sites, for example on Twitter, for some reason saves files without extensions).

In addition, the original Imagus has not been updated for 3 years (although I must say it remains operational), and the Imagus mod has a developer and is developing.

Learn more at "Imagus Reddit".

Still works great thanks to community updated sieves. Check the addon's subreddit for more info.

I cannot imagine using a browser without this extension now. Perfect!!!111

I've been using this add-on for several years now, absolutely necessary at this point with how useful it is, but in the last year or two, I've been having issues with reliably viewing YouTube thumbnails with it, along with a few other sites. The add-on really does need an update, it's been 3 years, it's about time for a revision.

it does 1 thing, and man is it good at it
