I installed Mozilla v1.6 a while ago … and have slowly been using it
more and more.  They have come an amazing distance with this
browser.  I really like a lot of the features … although there
are still serious issues with it.

One of the tools for Internet Explorer that I had picked up a while ago
was a tabbed interface “wrapper” called Scope.  Scope allowed me
to open a single browser window, and have it contain numerous “tabs”
that each displayed a different web site.  It was completely based
on the IE engine.  I used this tool extensively and would open
three copies of Scope each morning – each one containing numerous
tabs.  Scope was extremely lightweight and just worked cleanly.

All of this is now implemented in Mozilla.  I have now converted
two of my Scope “tab-groups” into Mozilla tab-group bookmarks. 
I’ll get the third one done this weekend.  I am also impressed by
the pop-up blocking, and some of the other configuration options. 
It comes up quick and just works.

Lastly, the DOM and ECMAScript support that is now in Mozilla is really
good.  Our WebFace libraries are now able to fully support the
Mozilla browser and so now our WebFace applications are completely
cross-operating system.  This is getting very cool …
