Junk shit Junk shit

absolutely rubbish....install a malware in the browser. Please get rid of this virus

Integrated redirect virus hijacks your new tab page. Uninstalling through Firefox Extensions page did not work. Extension no longer showed as installed but was still in toolbar and redirect virus remained. I had to search through my local data folder and delete extension file manually.

be careful. it integrates to firefox.

Changes your home page to crapsearch site

Do not install this piece of shit!

As it will replace your new tab with something pre-defined. Even though you may change this, this is clearly not what I'd expect from a Youtube downloader! Very annoying addon!

Do not install, will override your new tab with some dodgy search engine called Rspark

I'd rate it 0 if I could. DEVELOPERS: I KNOW YOU NEVER LISTEN TO USERS, BUT FOR THE FEW WHO CARE, NEVER, EVER, EVER, INSTALL ANYTHING THE USER DOES NOT KNOWINGLY CHOOSE WITH A FULL DESCRIPTION. IF YOU NEED REVENUE, BE HONEST. DON'T SNEAK CRAP ONTO OUR MACHINES!!!!!!!!!!!!!!!!

DO NOT INSTALL THIS PIECE OF SHIT ADD-ON

Spam: This will open search.rspark.com every time you open a new.

This is GARBAGE!!!
It changes your homepage!!!

When u install this addon it will make sure u get an irritating program installed with it. This program makes sure the every new page u load starts on https://search.rspark.com. Do not use this addon.

do not download.

Your new tab page will become search.rspark.com if you install this. Just remove it and the page will be restored.

Do not install this addon.

Rspark "search page" constantly pops up with this addon. Very dangerous. Would be a great addon if it wasn't doing this.

It works, but you have to put up with the rspark.com pop up search engine hijacker in your browser. SHADY!!!

THIS EXTENSION IS SPREADING THE TROJAN RSPARK THAT HIJACKS YOUR WEB SEARCH MECHANISM

Kann nur 720

Hijacks firefox and forces new tab to go to a dodgy, potentially dangerous website.

Avoid it.

Instala un hijack que te pone una ventana que te manda a un buscador. No instalen este addon.

Installs hijack that puts some of those bad search engines. Do not install this addon.
