Domain availability addon tool

[santis]

Hi,
4 years ago i have used an addon tool from Firefox for domain availability,
it worked like that: in any site i have selected with left click one or many words - than right click on selection and i had a option there - check domain availability,
it was very simple to use to ckeck domain availability,
but the problem is that i forgot this addon name,

can you tell me the name of this addon or recommend me a similar Firefox addon or a Crome extention?

Thank you.

I think you are talking about DomainLookup (click on that name to reach their website).
