Yeah, this is a bit confusing with Firefox on Android. When you “Add to Home Screen,” Firefox creates what’s basically a Progressive Web App (PWA) shortcut. Deleting the home screen icon alone doesn’t fully remove it — the entry still shows up when you long-press the Firefox app because Firefox keeps a record of installed PWAs. Here’s what you can do: Check in Android Settings Go to Settings → Apps and scroll for the name of the web app. In some cases, it will appear as a standalone app you can uninstall directly. Check Firefox Settings Open Firefox → Settings → Apps (or Add-ons/Web Apps). Depending on your version, there may be a section listing installed web apps with a remove option. Clear Firefox’s “site settings” Go to Settings → Site permissions → All sites, find the site you installed, and clear data. This sometimes removes the “installed app” record. As a last resort If Firefox won’t let go of them, yes, wiping Firefox’s data (or uninstalling/reinstalling the app) clears them. But that’s the nuclear option, since you’ll lose browsing history, logins, etc. Unfortunately, Firefox on Android doesn’t yet have a clean “Uninstall PWA” option like Chrome does. Until Mozilla improves this, the best workaround is managing them via Android’s app settings or clearing Firefox’s stored data for that site.
