Build ID: 20140923175406

Steps to reproduce:

Debug an .xul or similar in Browser ToolBox (former Browser Debugger). Have lines that are longer than the source code part of the debugger.

Actual results:

The source code is not wrapped, so you have to scroll to the right and back.

Expected results:

Wrap such lines (ideally: dynamically, i.e. wrap at white space only, do not split words). Even better: have an option to turn wrapping on/off.

This would be useful regardless of what source code line length Mozilla or anyone deems a 'standard'. I.e. you could have a line of eighty characters or less, but it wouldn't fit in the source code area, because of e.g. a small screen, a need to see wide stack trace or wide listing of variables/watches etc.

I agree this would be useful to have, especially since we want to evolve the debugger towards become more editor like in the future.

Ever confirmed: true
Summary: Browser ToolBox (Debugger) should [have an option to] wrap long lines → Optionally wrap long lines in the debugger
Easy horizontal scrolling with <shift>+mousewheel like proposed in Bug 1263105 would really help here.

did we recently add support for a pref?
