Auto open Links from newly arrived emails

Hello, I need a script that can be run in Firefox or Thunderbird, that will automatically open links with specified starting address (for example [login to view URL]) for all newly arrived emails. To clarify: when new email arrives to inbox (gmail or whichever) script has to open new email and then open links from it. I am getting links over email regularly, and it would be easier if they should open automatically so I don't have to click on them everytime. it would save me a lot of time. Thank you
