Add-on can't connect with Strongbox Pro app. Useless. Doesn't work.

My biggest grievance is when you press "dismiss" on the strongbox password filler, rather than just disappear, it then asks "hide for awhile", "hide on page", "hide on domain". This absolutely sucks.
I don't have the answers to those questions, I don't even know what "awhile" is either. Why not just hide it when I press it? Its so stupidly annoying. Add another button then like "dismiss" and "options" or something. Like, its an overlay on the page and I have to make that decision on permanency right now? No I want the overlay to f off out of the way of the page its overlaying
Otherwise it works great.

Is Strongbox AutoFill Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Strongbox AutoFill requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Strongbox AutoFill has earned a fairly good reputation and likely can be trusted.
