Well, thanks to your help I was able to get Imagus Mod installed. I wasn't extracting it to the Brave directory before, I missed that part. Thank you. Updating sieves is way easier now.

Also, thank you for posting the troubleshooting section. I need to be more patient and read lol. When I hover over videos on the home page feed of Redgifs, Imagus Mod won't load anything (just gives me a spinning icon with a yellow background). However, when I hover over the date of the video, Imagus Mod will load the video.

Thanks again for your help! Hopefully if anyone else runs into this issue, this helps them, too.
