It's basically malware. Don't use it, it injects itself into new tabs you open and redirects to a sketchy at best search page, which generates money to this "dev".

Love this extension in Brave. In Firefox it does not work. Every time I open a new tab, this extension opens instead. Also there is no save button so I was constantly adding a new URL, and finding the prior ones gone.

Ive reported this addon for abuse, like another reviewer says, having this addon enabled directs you to https://search.rspark.com/?service=multiple-url-opener each time you open a new tab without giving it permission to do such.

works, but changes new tab from Blank→Home
and Home to: https://search.rspark.com/?service=multiple-url-opener

without asking!

Malicious extension, report it for abuse. Don't let them fool you, even though you can change the home page in options, the extension will restart the rspark.com home page everytime you close-restart firefox.

Well, it functions fine. It installs adware though. Your home screen will become rspark.com and apparently you won't be able to simply change it in settings. Apparently, you have to completely reset Firefox's settings to get rid of it.

The best thing to do with this add-on is report it for abuse.

Te instala buscador rspark.com

This crap change you start website for rspark.com

try hitmanpro or malwarebytes for remove these.

Modifies default search to adverts

One star for changing the start page. Very basic addon, not very useful.
