Adding sites to permissions dialog

[Odin2]

This is probably a dumb question--but I can't see how to add a site to the permissions dialog. I use NoScript, and I thought NoScript might be the problem--but NoScript won't let me whitelist about:preferences.

There hasn't been an "about:permissions" dialog in Firefox since version 44. What other "permissions dialog" might you be talking about?
And the only way to have a site listed on about:permissions was to go to a webpage and adjust the permissions to something non-default.

Type about:about in the nav bar and you can see what is available for about pages.
If you visit a site and you get a NoScript warning you have the option to allow or deny.
If you have inadvertently disallowed or labeled a site as untrusted there is an item in about:config which you can edit, adding or subtracting, watch syntax (spaces mostly, etc.)
noscript.untrusted
If you have a great number of untrusted items you can copy to a text editor,
make your edits easier to read and modify and paste back in noscript.untrusted
It's good for beacons and trackers which show up on sites as untrusted.

Thanks, both, for your responses, but I'm still at a loss.

1. The permissions dialog is at about:preferences#content, accessed by clicking the Choose button.

2. It seems I must have mistyped the URL in question, which is is actually about:preferences. (Sorry.) As I said, NoScript does not allow me to whitelist that site. If I try, the option to Allow is grayed out.

(Grumpus, much of what you say looks interesting, but I don't know how it applies to my problem.)

Are you referring to cached web content or Offline web content and user data
If the Offline Web Content there does not appear to be an "add" feature but it could need to be triggered when a site requests it.
Otherwise there's no other Content except for the cached web content which is just a bucket you empty.

Grumpus, I'm simply trying to prevent notifications from a particular website or, possibly, my antivirus provider.

No, NoScript won't allow you to block about:preferences.
about:preferences (& various other about: preferences, those that are grayed out) are [forced] whitelisted.

Which is it: do you want to allow or deny a website permission to display notifications?

In any case, websites that you haven't whitelisted will ask for permission via a doorhanger (a prompt that hangs off the icon on the left side of the address bar). If you accept, they then end up in the list under Options/Preferences → Privacy & Security → (Permissions) Choose. You can remove them from the whitelist there.
You can also click the icon on the left-side of the address bar; at the bottom of that doorhanger you can see if you've granted the site any special permissions and remove them by clicking the circled X.
Lastly, you can right-click a blank area of the website and choose View Page Info, then Permissions. There you can switch "Receive Notifications" to "Use default" (ask), Allow or Block.

Thanks, Gingerbread Man. For whatever reason I've just now seen your post.

My interest was primarily in blocking pop-ups from Epson. At the permissions dialog for Epson.com, I see that the [checked] default for pop-ups is Block, and the [checked] default for notifications is Always ask. So I don't know why I get frequent pop-ups from Epson nagging me to install software I don't want. Is there no way to stop these pop-ups?

[Gingerbread Man]

Can you post a link to the page where that happens, and maybe a screenshot (you can upload it to a site like imgur.com and post the link here)? I see no pop-ups on https://epson.com/usa. It's difficult to know if you're seeing a pop-up window that Firefox thinks is user-requested, an add-on installation prompt or something else.

Thanks again, Gingerbread Man.

I'm guessing it's not a Firefox issue after all, as the pop-ups aren't associated with a particular page. I probably should ask at the MS Community forum.
