Double-clicking the space between two words no longer selects both wordsI bisected this regression to this mozilla-central pushlog:

As one of those people who likes to obsessively click and select text when reading, this regression makes me sad. :(

I'm now having trouble consistently reproducing this word selection problem. It seems to be correlated with the "Findbar Tweak" extension in my default user profile, but not when I install Findbar Tweak in a new profile.

Have you been changed layout word_select.eat_space_to_next_word in about:config?

Thanks, Alice! Changing the layout.word_select.eat_space_to_next_word pref to false fixes the problem.

For some reason, my default user profile thinks layout.word_select.eat_space_to_next_word's default value is true but a clean profile shows the expected default value false (for OS X). This problem no longer sounds like a word selection regression, but I don't know why my profile (sync'd to another Mac and Firefox for iOS) thinks the default value for layout.word_select.eat_space_to_next_word should be true. I may have sync'd Firefox running in a Windows VM when I was testing recently. The default pref value is true on Windows, so maybe Windows "polluted" my sync prefs?
