http://ffinst25. download/ popped up on my screen and then i was subscribed to some tv website i just downloaded a new version of firefox

Sorry to say this is a FAKE site. This is a scam to try and trick less experienced users into installing a fake extension to infect your Firefox.

Mozilla has already blocked a number of variations of these bad extensions (often with FF in name) as listed on addons.mozilla.org/blocked/

New Firefox versions or updates are only down by download from mozilla.org like say www.mozilla.org/firefox/all/ or by internal software update (with a .mar file) whether on Windows, Mac OSX, or Linux. https://support.mozilla.org/en-US/kb/update-firefox-latest-version

Mozilla does Not provide Firefox updates on random weird name urls like the one you encountered possibly from a malicious Ad.

For people who do not want to load the url it is basically a page like the image example below.

thunderbird accothanksunt. and i'm just trying to get secure online.

There is no such thing as Thunderbird accounts. Thunderbird is a email client you use to manage email address you have instead of using web based email aka webmail sites for email address in a web browser.
