'Get information from open tabs in Firefox

How can I get repetitive information like "Title" which is repeated in all the open tabs I have in Firefox? Please note that I am not referring to the tab title, but to an actual text on the webpages which is something like "Title : First Store" and on another page the text is repeated like "Title : Second Store".

I don't want to use python to do this. I would like to do this on the open tabs in Firefox ... using an extension or another way. Please help.
