Firefox

Alex Russell has pointed out that Firefox 3 has some quirky issues with JavaScript arrays, namely, an array made from a literal has a different constructor than an array made from instantiating the global array object. Long story short, the below is true:

[].constructor != new Array().constructor

Update

It seems like this is a Firebug-specific issue. If you try to evaluate the above in Error Console, you'll get false.

One of the changes in Firefox 3 Beta 3, which has just been released, brings the object destructuring shorthand to JavaScript 1.8. Why would you need object destructuring in the first place? Commonly when you need to pull certain values out of an object structure, as demonstrated here. The introduced shorthand sprinkles a bit more of syntactic sugar into object destructuring assignments. Read on for concrete examples.

John Resig (author of jQuery who recently joined Mozilla Corp) wrote about Firefox 3 will have native support for document.getElementsByClassName(). This is what almost all web developers want; almost all Ajax libraries implement this.

I just saw Ben's post about an experimental feature landing on the Firefox 2 nightly. Basically, Firefox 2 will have a better way to handle feeds.

Currently in Firefox 1.5, there are two ways.

People, are being totally stupid because of Flock.
When Firefox 1.5 came out, someone quoted (on digg, possibly)...

Wow, Firefox 1.5 has a new error page just like Flock!

God damn it.

Flock is built on top of Firefox, not the other way around. What are people thinking?

Another misleading story from CNET: Mozilla take wraps off Firefox 1.5.
Let's see:

Firefox 1.5 also supports new Web programming standards, such as AJAX, that enable more graphical capabilities in Web pages.

I just saw this section from the Mozilla Corportation's press release:

With Firefox 1.5, Mozilla continues its search partnership with Google in the Americas and in Europe and begins a new search relationship with Yahoo! in China, Japan, Korea and Taiwan.

Some guy on the net thought of a clever way to make Google Analytics unable to collect data under Firefox browsers. First of all, he spelled Firefox wrong. It's "Firefox", not "FireFox". He achieved this by using the adblock extension (not "plug-in", as he said) to block *.google-analytics.com.

After using this "counter-anti-block" method, the only way to avoid is to turn off JavaScript.

The upcoming Firefox 1.1 is not just a new version of Firefox. It means a lot of great new features and underlying state-of-the-art technologies.
