I've been using Tabliss on Firefox without any issues, but immediately after updating to Firefox 151.0, a frustrating new loading delay started happening. Prior to the update, new tabs loaded instantly. Now, whenever I open a new tab, the page sits on a completely blank screen for about 2 seconds before the Tabliss layout, background image, and widgets finally pop in. Because this issue did not exist at all before version 151.0, it seems like the latest browser update changed how extension-based new tabs are cached or initialized, causing a new rendering bottleneck.
