Firefox 3 and the text/html-object

[molendijk]

Some people give classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" to their text/html-object (for validation purposes).
Firefox3 users may have noticed, however, that this causes the object not to function at all. So don't do:

<object classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" type="text/html" data="bla.html" ></object>

but

<object type="text/html" data="bla.html" ></object>

(A couple of threads I posted suffer from this. I'm too lazy to correct it).

Validation purposes? That inane GUID is for IE/Windows/ActiveX, and denotes a handler. It's not really the use to which the 'classid' attribute is meant to be put.

Validation purposes?

That was explicitly mentioned here, but now I see that they suppressed it.

It was the whole <object> scheme that was used for validation purposes (in order to avoid the dreaded <iframe>). The standard <object> requires nothing other than the type and the data. IE is the one that requires the classid-GUID hack.

IE is the one that requires the classid-GUID hack.

Yes, and that's why I used to apply the hack, since it didn't seem to bother the other browsers ... until FF3 came along.
Sidenote: even IE's version 7 cannot load pages from a foreign domain into the text/html-object.

If you follow the instructions (using the conditional comments) from the link in your first quote, you will not have the problem mentioned in your second quote.

I did that first. Then I noticed that non-IE was not bothered by the classid, so I took away the conditional comments. But now it seems that we need them after all, because FF3 doesn't like the classid.
So yes, that's what I wanted to say: don't use the classid for non-IE.
