Quickly scroll to top or bottom of the page on Firefox for Android
My plan was to change icon to ‘scroll-down’ when the webpage is at top, and to ‘scroll-up’ when the webpage is at end. But, pageAction.setIcon() is not supported in Firefox for Android. So, there goes my dream.
The pageAction icon moves to a dropdown in text form. I thought that pageAction.setTitle() API may be able to change that text (‘Scroll Up’, ‘Scroll Down’). But again it is not supported in Firefox for Android.
