There is an abbreviation translator Add-on for Firefox and Chrome called
Acronym / Abbreviation Expander Add-on / Extension | ABBREX.
This works similar to the built in abbreviation translator on ECF by underlining abbreviations it finds and if it is in its database it will show the definition of that abbreviation.
It's community driven, which means that any abbreviation translations someone enters can be seen by anyone else using the ABBREX Add-on. You will need to register on the ABBREX site to become a member of the community. Registration is free.
If a particular abbreviation applies to more than one definition all of those definitions will be shown in the popup if they have been entered into the community database.
Here is an example of a multi-vendor popup that I have entered:
So far I have entered all of the Vendor abbreviations listed on this thread down to this point.
This abbreviation translator will work on any abbreviation, not just vendors, so if the database has ECF, for example the popup will show "E-Cigarette Forum" or anything else that ECF might stand for that was entered by someone else.
