I built a customizable context menu extension for Firefox that works well on both Desktop and Android.
I often found myself missing powerful context menu tools when browsing on mobile. Native context menus on Android are typically limited, so I built "Right Click", which lets you select text and run custom API calls on it directly.
How it works:
Desktop: Adds items to the standard right-click context menu and custom popup.
Android: Automatically displays a custom popup when you select text, giving you immediate access to tools without fighting the native UI. It supports some default actions (such as translation and text-to-speech), but you can add more.
Thanks for all feedback, especially on how the text-selection popup feels on different Android devices.
