Select More by Firefox user 12918656

This add-on makes it easy to select a block of texts, especially the programming code which sometimes hard to be selected when the edge of text is narrow.

How to Use:
1, Select texts almost from the beginning to end of them you want to select.
2, Right click to show the context menu and choose "Select More" to select exactly at the beginning to end.
3, Copy it.

By enabled by option setting, right double clicking will do the same thing.
