Redirects to spam website.

Rubbish

This app is rubbish! It opens a new window or tab and takes you to very dodgy looking advertising. My ad was in Spanish ofering to send money to people for their birthday. Given the "about this extension" is a history of Facebook, it is likely a scam

Spam. Redirects to spam website.

doesn't do anything, only opens a webpage with advertising

Only thing it does is take you to a website to buy some crypto (meme-coin).

Doesn't do anything except open a webpage with a picture of a dog.

thanks

doesn't work and breaks the video.

found one that works
https://addons.mozilla.org/en-US/firefox/addon/video-downloader-profession/

Doesn't work, no download button.

App fasulla che indirizza verso sito finanziario, probabile truffa.

redirects to https://bdaymoney.com/

Just opens a oneclick site.

Website it sends you to has a Cloudfare error; "Invalid SSL certificate Error code 526."

Assuming it's ever worked, it's useless now.
