Does anybody know a way to remove v9?
I am sick of it getting me redirected to all kinds of pages? What should I do?

See this forum for removal instructions:

How to Remove V9.com Search Redirect (Browser Hijacker Removal Guide)- AnviSoft

Thanks, farvaknowsbest

I also found some https://support.mozilla.org/en-US/questions/944449
V9 Redirect Virus

I did the thing where I had to type about:config in the browser's search bar. And I also downloaded an antivirus program, Malwarebytes.

:)

Glad you got it figured out. Sounds like some nasty bloatware/malware.
