Unfortunately there is the misconception that running a google extensions is safer than running an exe, for unexperienced users. Plus people may think it's safe because it's from Google
How is the situation for Firefox extensions?
I'm afraid since this scam is quite easy to pull is just going to get worse the situation with these extensions..
Agree and it's sad, google and firefox should worry a little more for the customers, i know they are big platforms and should be hard for them to review their apps one by one, but c'mon we are almost in 2019 and that job could be done by artificial neural networks. A simple grep to verify if the app is hacking information from the main sites like google, outlook, or some social networks.
Is intolerable the fact that anyone can make this kind of apps and publish them as if there were no law.
