Add a fullscreen button to bottom-left corner of any webpage
This userscript is designed primarily for mobile phone users who want to view web pages in fullscreen mode. Unlike desktop browsers where users can press the F11 key to enter fullscreen, mobile browsers typically do not provide a direct fullscreen option.
By adding a small, always-visible button to the bottom-left corner of every webpage, this script allows users to easily switch to fullscreen mode. This helps eliminate distractions such as browser UI elements, making it more comfortable to read or browse content without interference.
The script utilizes the standard Fullscreen API and works across most websites that permit fullscreen access.
