AOS not showing up for some users

My Windows 10 machine has multiple user accounts. The admin acct has the AOS icon showing up in the menu bars of browsers (Firefox, Chrome). The user acct I usually use for myself does not have the AOS icon showing in the browsers. Avast UI Settings shows Web Shield on, and customization settings are the same as for the admin acct.

How can I get extension turned on?

Hi, you can always download/install them directly from the corresponding web store.

If one account has AOS working properly, wouldn’t the files already be on the computer? I looked through the C:\Program Files\Avast directories, but nothing stood out as constituting the AOS extension. If I could locate the files on the computer, would I then be able to activate AOS for the browsers missing it?
