On desktop Hover Zoom is life changing way to browse memes and gifs. One thing I struggled with when I moved to Lemmy was Hover Zoom support. While it worked with imgur links, these are few and far between. I had given up hope when I finally discovered Imagus works perfectly.
Imagus is a browser extension for Firefox that allows users to enlarge images and display images/videos from links with a simple mouse-over. It is similar to the Hover Zoom extension, which is a popular tool for browsing memes and gifs on desktop. However, Hover Zoom has been flagged as spyware, so users may want to consider using Imagus instead. Imagus works with a wider range of links than Hover Zoom, including those from imgur. The extension also has customizable settings, including an expandable set of rules for getting larger images, media, or other content.
