Is Compatibility Verifier dangerous?

Everyone should realize that all the browser extensions including Compatibility Verifier, no matter if they are helpful, are the weak spots for every browser where they are installed. The browser vendors release update patches periodically, due to which the safety of the browser is perfect. The existence of any extension can make the try to protect the security of the browser impossible. And, as a consequence, some online offenders can use your computer or collect your private information. If you cannot imagine your computer without add-ons, then I suggest to install extensions from well-known software vendors only, perhaps it will promote you to keep your PC safe. But you should know that it is better not to install any browser add-ons at all.

But if you still need to have one or another add-on so you should be ready that the add-on will have approval to record your sensitive data that you enter on diverse web pages and can pass it to the third parties. You should understand that to download a browser extension is like installing an utility. Will you install software if you do not know its producer? I think, no. So, you also should think about the extension that you are going to install.

Compatibility Verifier, as an advertising add-on, is more dangerous, because you cannot be confident that the advertising notification is genuine and that the website that is mentioned in the announcement is safe. If you are eager to have Compatibility Verifier or any other add-on that shows you special offers then you should be ready that it can deceive you.
