Looks like RC3 and final might be the same thing. I went here: ftp://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.0/win32/en-US/ , and the version number of the download is the same as that of the "RC3" build I installed earlier.

This is (the only?) thing I miss from IE. Thankfully, this Firefox extension adds the capability.

Quoted: Allows you to open any file from the internet into the OS assigned program. This is similar to IE's 'Open' or 'Run' file download functionality.

Skin Firefox to look like IE7. It works very well.

Quoted: Vista aero style. clear and cool!

Yes! This is the one thing I really hate about Firefox.

Quoted: Firefox should have the option to try to open application/octet-stream (binary, can be executable files) from a temp folder instead of always having to save it to the desktop.

Trying to get a development build for Firefox 2.0 (not Firefox 3.0).

Looking for a version with symbols. This might work.

Quoted: A Firefox version for developers
...
You need a special Firefox version with which you can get good results from WinDbg. It is a current version built by a developer from the official source code with no official branding enabled. Such a current trunk version can be found under [2]. Download that file and unzip it somewhere.

Interesting.

Quoted: In his first post, Gian reports some demographic data they've gleaned on Firefox and IE users. To nobody's surprise Firefox skews male (55% of its users are male versus 50% of IE's users). Firefox skews young (22% of Firefox users are younger than 22 versus 13% of IE users). And maybe most interesting, Firefox skews wealthy with about 50% of its users making more than $75k per year (39% of IE's users make over $75k).

Quoted: okay, not entirely true. i recently got a comment on how sharepoint might not make it in a company because one of the features, a rich editor for html that is used in rich edit areas, wiki, blog, etc., does not support firefox as a browser. basically you can still edit, but you don't get the WYSIWYG environment.
...
well, there are a couple of options.

Quoted: What if you could say goodbye to alert and not-so-useful logger scripts and have a real debugging API to debug Javascript. While it hasn’t made it to the public yet, the next version of Joe Hewitt’s Firebug will finally give us an easy to use, full-featured debugging environment for Javascript.
