Not subcribing with Brief automatically (Allow Feed Preview)

[LukasThyWalls]

Hello

Since Firefox got rid feed previews, there is some extensions to have that feature in the browser, however, the Brief approach is to directly add it to subscriptionns when is selected.

The problem is if you use an extension to preview the feed (For example Feed Preview https://addons.mozilla.org/es/firefox/addon/feed-preview/) it doesn't work with Brief installed because Brief directly adds the subcritption, not allowing to show the preview with Feed Preview, with any option to see the Feed. I would want to look the preview and then use the subcribe button there (it can be configured adding a URL, i don't know if it's possible to add feed in that way in Brief)

Is possible to disable this in Brief or it's possible to change this behaviour (with an option, etc.)?

Thanks.
