…competition, we deserve options. Microsoft, Google, Apple, Opera and Mozilla are all vital to the ecosystem of the web; to push each other to become better and to foster innovation that everyone gains from. I work for Mozilla, but I would definitely not want to see Firefox (or Gecko's rendering engine) as the only one out there. We need a balance to together form and grow the future of everyone.
To me, when it comes to just one owner, one rendering engine compared to the …
…scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox.
Tony Gentilcore compared this approach to JavaScript libraries on the Surfin' Safari Blog:
There are many clever techniques for working around this performance bottleneck, but they all involve extra code and browser-specific hacks. Instead, scripts which do not require synchronous execution can now be marked as either async or defer .

…browsers (in some cases where they don't even yet support the particular functionality - for example Opera and radial gradients).
In the past (and some of these are 2-3 years old now), I decided to focus only on those browsers which supported a particular technology. I had separate Firefox and Webkit versions of the gradient tools because they supported quite radically different models of gradients, which made a single interface to producing two separate versions of a gradient confusing, …
…it can't work everywhere yet. It won't work in IE, Safari or Opera since they don't support typed arrays, nor in Chrome since it doesn't support WAV data URLs. So currently speak.js only works properly in Firefox. However, the missing features just mentioned are not huge and hopefully those browser makers will implement them soon. It is also possible to implement workarounds in speak.js for these issues (see next comment).
Help with improving speak.js is very welcome! …

There's still no support in Internet Explorer, and there has been no trace or indication in the previews in IE10 that it will be added. For now, the History.js polyfill could prove to be a sufficient option for Internet Explorer, but I only see it as an interim solution.

Code injection, error throwing
In a blog, Opera Software Developer Relations team member Tiffany B. Brown looks at code injection, error throwing and handling and mobile debugging. She notes Opera Dragonfly and its remote debug features provide a way to debug mobile sites from their desktop. Brown mentions WebKit's recently added remote debugging capabilities, folded into Google Chrome…
…bug? Safari, Chrome and Firefox suffer from this issue. Opera doesn't (but then, does it also block on JavaScript - I have a feeling it doesn't). I didn't test IE (partly because I was sure it would, partly because I didn't want to start my VM - if someone could confirm, that would be super).
Right now, I'm not sure what's at the root cause, but I do know it's putting some web sites at risk.
