Layout.word select.stop at punctuation
From MozillaZine Knowledge Base
This preference controls the selection behaviour when double-clicking text as it relates to punctuation surrounding the text. It also affects the way some shortcuts (e.g. Ctrl+Left/Right arrow) and Ctrl+Backspace) work when editing text.
Possible values and their effects
"Word" selection includes surrounding punctuation and only stops at whitespace, so that for example double-clicking example.com/the/path and the other above-mentioned shortcuts select the entire URL. (Default on Linux/Unix and OS2 for all apps except Minimo and Firefox after bug 190615)
Word selection using the above mentioned shortcuts ends at punctuation characters. (Default on Minimo and all platforms except Linux/Unix and OS2)
