Popup from browser or OS?

Post by ron_1 » 2019-12-01, 00:22

When I login to my Centurylink email, I always get the popup below (cropped the width to save space). This may be a dumb question but is this popup generated by the browser or my OS? If it's from the browser, does anyone have any idea how to stop it?

The webmailer is asking the browser if his own webapp should be added to the browsers list to handle content, in this case for mailto links. Seems a bit odd to me that this doesn't come in a dialogue box with more options, but in a bar with no decline option. I guess it will return after just clicking redX.
You could add the app, then go to Pale Moon >Preferences >Applications, look for mailto links and set it to another default app like Interlink, Thunderbird,...

You can click the close button on the bar. It's not modal so you're not forced to make a choice and can ignore it each time it appears.

@ron_1 - the bar is a standard feature inherited from Firefox to implement a non intrusive alert - you'll see it show up when popups are blocked too, for example.

Not sure if this will help, but in about:config what is the value of network.protocol-handler.warn-external.mailto ?
If it's set to true, see if it helps to reset it to false .

It's set at false, which appears to be the default. Any other ideas? At the very worse I suppose I can just click Add Application since I'm tired of ignoring it.

Yes, you can do that, it just gets added as a handler as seen in the earlier comment's screenshot.

Apparently it can be hidden with css. There are a couple of SUMO answers (1, 2) + Mozillazine thread that suggest hiding this type of message with userChrome.css or Stylish (Stylem).

One of the answers is tailored to messages from Yahoo, but can probably be adapted (based on your screenshot) by replacing Add Yahoo! in that solution with Add CenturyLink - the other answer appears to hide such messages from all websites.

(also, you might want to install Dom Inspector, if you haven't already, in case the selector provided in those answers turns out not to work in PM and needs to be adjusted)

Thanks coffeebreak for going above and beyond in trying to help me with this. I just went ahead and clicked Add Application though as I do not want to install yet another extension.
