How to remove a safari extension

Everybody is happy and thankful, but the single Safari extension that shows up for me, Wotja, has neither an uninstall button, nor a button to turn it off. It's blank, not even grayed out, where these buttons should be. Perhaps it's an app that has been stationed there?

You are my hero!

I just spent about an hour trying to figure it out!

I love you now and forever!

THANKS SO MUCH! I have been trying to find out how to do this for what seems like FOREVER. I hope this removes the annoying bell sound I've been getting on my Mac. Sounds like a boxing match start bell when it goes off

Thanks man! I had this really annoying utube thing

Thank you to all of you for the tip! I thought Safari would have their own "Extensions" menu item or something along those lines. It NEVER occurred to me to look in the Preferences. 😮

BIGGEST THANK YOU. Been trying to solve this for the last 2hrs. Cheers.

spot on... cheers mate, its a bit diff to firefox. Thanks man

Thank you! it worked for me.

You rock, Richard Walker.
