Question

I saw a ActiveX plugin for FireFox here

I’m trying to use a Bematech printer in FireFox, using this following <OBJECT> tag, that works fine in Internet Explorer

<object id="BemaPrinter1" height="14" width="14" classid="clsid:310DBDAC-85FF-4008-82A8-E22A09F9460B" VIEWASTEXT></OBJECT>

In FireFox don’t print and don’t show any message.

Can someone help me ?

That plugin has some documentation, feel free to read it. Indeed, on the very first page it says (under Security):

The plugin has some security related features to limit the risk it
might pose to users by making ActiveX controls available in Firefox.
First of all, it is using a special MIME Type so that it won’t get
triggered by sites that were not specifically designed for it.
Additionally, it supports lists of well known CLSIDs and PROGIDs so
that it can be limited to use with specific controls and interfaces.
Finally, it can be “site locked” to make sure it’s only being used by
a predetermined list of domains.

The first condition means that you need a TYPE="application/x-itst-activex" attribute on your <object> tag. The other two security features are optional even though I would consider them highly recommendable – they have to be enabled by changing the source code of the plugin and recompiling it. So as long as you are using the vanilla build adding the correct type attribute should be sufficient.
