In Linux version, chars like "/" are not treated as word separators, so Ctrl+Backspace removes everything up to the beginning of the line, and Ctrl+arrows work just like Home/End. It would be nice if the Linux behaviour followed the Windows behaviour, as it is rather handy in correcting mistyped URLs or changing URL parameters. This may be considered low priority as it's mainly a feature for advanced users, but it affects browsing comfort nevertheless. Reproducible: Always Steps to Reproduce: 1. Type a complex (but valid - no spaces etc) URL in the location bar (say, https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&format=guided) 2. Press Ctrl-left a few times, then Ctrl-right a few times, and observe the behaviour 3. Do the same in the Windows version, and compare the behaviour to Linux version 4. Do the same with Ctrl-backspace shortcut Actual Results: Ctrl-left instead of moving the caret one URL part to the left (subdomain, parameter etc), double-acts as Home Ctrl-right double-acts as End Expected Results: Starting from the end and pressing Ctrl-left several time, the sequence of caret stops should be "guided", "format", "Firefox", "product", "cgi", "enter_bug", "org", "mozilla", "bugzilla", "https".
By the way, I forgot about "=" as a potential candidate for inclusion in word separator character list.
Looks like it can be turned on by setting layout.word_select.stop_at_punctuation in about:config - still, it looks like it would make sense to make it separate settings for the location bar and the content pane. The double-clicking behaviour in content pane and Ctrl-navigation in location bar seem to be different enough not to use the same settings.
