Not only internal applications, even commercial packages. IBM works on ajusting all middleware applications eg Lotus based also to seamless integrate Ff as UI.

This is very good news. IBMs decision will get into the press, IT and otherwise, and will get Mozilla lots of publicity. Moreover, many companies will come to the conclusion that a product endorsed by IBM can't be all bad. IBMs committment to certify all its software for Firefox is extremely cool and will further help with adoption. Other companies will follow where IBM leads, if only out of fear that their customers will become restless when they see no action from them.

Any information whether IBM will bundle Firefox with their products?

I forgot a few things:
** Are there any efforts to get Firefox into internet cafes and kiosks? It would be ideal because it's free, themable (great for cafe logos), multi-language, secure, easy to customize with extensions and runs on Windows, Linux and Mac. I have seen a Linux+Netscape cybercafe solution once, but that was a sorry mess. So far, cybercafes in Europe are dominated by MSIE and Windows.
** What's with the offical automatic installer (MSI)? Will it be ready for Firefox 1.1? Does Mozilla foundation have an partners in business and government who will publicly roll out Firefox?
** Is there a project to help ISPs bundle Firefox and Thunderbird for their customers? A project of this kind might include a network of extenstion writers who make ISP-specific stuff (download volume counters, extensions to access special content, hotline interaction), ISP themes writers, etc.

I forgot to write that also IBM works on Firefox and Websphere server software:

"A job ad posted at IBM's Web site said an emerging technologies team in IBM's software group wants programmers for 'enhancing the Mozilla Firefox Web browser with new features complimentary to IBM's On Demand middleware stack.'"

And IBM is not the only company to endorse it officially : sure, that's the first big one. But I have been in quite a number of SMB that not only encourage Firefox for their employees, but some even prohibit the use of IE.

It is actually quite interesting to see that, small business that doesn't have regular IT staff are pushing for FF in a will to reduced security issues.

IBM and its 300k employee worldwide makes sense to me : IT managers thought this out, studies were made, blablabla. But SMB are more surprising as the switch is based on the fact that more and more believe to the statement that FF IS more secure than IE. Despite MS effort to say otherwise...

Rock on!

I have a good friend at IBM, and he laughed when I told him this--the site all of IBM's employees use for making travel reservations only works with IE, and evidently it's not the only one. This strikes me as more marketing flash than substance, the test of if they're serious will be if IBM employees can really do their jobs without using IE a year from now--right now, the answer is no.
