That Show Notification thing is hella useful when you gotta catch something on the page without overloading it. Saves time, keeps it smooth.

Malicious things occur with this extension. Injecting various things depending on what the page is (shopping affiliate links for an example). Anything willing to inject isn't worth using

Was great when I first installed quite some time ago. Recently I started noticing page redirects from the Google Search results; this would be any result. When clicking on a link, such as Amazon, the page would redirect to some rando site seen in the URL box with loads of tracking information, sometimes it would do 2 or 3 redirects, and then finally go to the page I originally clicked on.
Clicking the back button would go back to the search results, and clicking the same link would go directly to that link. This made tracking what was going on a lot harder.
But after disabling an add-on and doing search result clicks, I came to this one and when I disabled it, the redirects stopped completely.
This app is redirecting your clicks and collecting information, or self-affiliating like the Honey debacle.
Remove this app and clear your cookies to make sure you have none of these tracking/affiliate cookies left.
