Firefox Gets Massive JavaScript Performance Boost

Heisenbug Re:Performance is great and all (462 comments)

Logging and debugging. I haven't delved into the likes of Firebug to see how it works ...

Delve! Firebug has crazy things like the ability to set breakpoints in code currently running in the page, and then when you hit the breakpoint, run code from the context of the line you stopped at. And lots lots more. As someone who's been out of web programming for a few years, it blew my mind.

Submission Text Formatting Tips

We support a small subset of HTML, namely these tags:

  • i
  • p
  • br
  • a
  • ol
  • ul
  • li
  • dl
  • dt
  • dd
  • em
  • strong

"ecode" can be used for code snippets, for example:
