Brave prompts about installing external extensions, like Chrome

Description

Sometimes when you’re installing Brave, you’ll get a random notification that states that a new extension has been added. In my case (example below in the screenshot), I had Ace Streaming installed which is attempting to add an extension every single time I install Brave.

@LaurenWags ran into the same issue before with LastPass but she did have it installed. We assumed that the native application was attempting to install the extension.

However, @bsclifton mentioned that he had the same issue occur but he never installed LastPass.

We need to figure out why LastPass is installed randomly sometimes and we should be blocking native applications from attempting to install extensions.

Steps to Reproduce

I don’t have 100% STR but I think this is happening when a native application attempts to install an extension in a new browser. However in @bsclifton case, he mentioned he didn’t have LastPass installed but still received the notification.

Actual result:

Expected result:

• We shouldn’t be installing random extensions on first launch (@bsclifton case)
• We should be blocking native applications from trying to install extensions on b-c

Reproduces how often:

• 100% reproducible once you have a native application that attempts to install an extension

I’ll step back from this decision and leave it to product and security teams.
