I just installed the new FireFox and by doing so, I lost a little trick that
I have been enjoying greatly so far: whenever I click on a link from outside FireFox, I

The instructions to enable this feature are in the FAQ but a bit scattered,
so here they are in a more concise fashion:
- Add the following to your user.js:
// Stop reusing active windows: user_pref("advanced.system.supportDDEExec", false);
- This file doesn’t exist by default, so you must create it. On

c:/Documents and Settings/[user name]/ApplicationData/ Mozilla/Profiles/default/[random chars].slt/user.js
- Download and install
- Select Tools > Extensions, select Tabbrowser Extensions and click the
small Options icon.
- Expand the General node.

Note that the "small Option icon" in the Extensions window is not only
minuscule but doesn’t look like a button at all (no push affordance). It’s
the label with a check mark on it. I find this inconsistency in the FireFox GUI annoying: why should options for extensions be in a different
menu than the regular preferences?
Anyway, FireFox is a cool browser, and even if the progress in terms of
features is pretty slow, it is still light-years ahead of Internet Explorer,
