[Need help] Which setting disables embedded pages?

[XaaRii]

For some reason, after enhancing my prefs.js with your ffprofile, some pages (fe. microsoft or some payment providers) now won't load embeds saying something along the lines of "Firefox cannot open this site, the web microsoft.com won't allow firefox to be shown as an embedded part of another website" (rough translate). Now, this happens only after i apply ffprofile's configs so i'm pretty sure the cause is a specific tweak or two. Sadly I couldn't figure out which one does it.

I am not aware of any used tweaks that would mess with embeds, but I am no expert. Thus, i attach a hastebin with my prefs.js file content: https://hastebin.com/ihinadonin.sql

If someone could point it out to me, I would be really grateful.

Check if it is Referer related. When you installed uMatrix, you will need to allow thirdparties (script, xhr, frames) on many sites for loading embedded content.

Otherwise try either step by step which setting is causing the issue or try things like only using half of the config and checking in which half the problem is.

When you identified which setting is causing problems, we can add a note to it.

Somehow i didn't get a notification I'm not sure where was the broken page, I just remember that it jumped at me when i opened microsoft profile page. Now, I removed referer (Allow all referers) and I don't see any broken pages. It's not ideal, but as the webpage suggested, i can always use an extension to manually allow/deny referer per page. (the one ffprofiler refers to is not available anymore, but i found https://addons.mozilla.org/cs/firefox/addon/togglereferrer/ and that seems kinda nice - opensource)

Huge thanks for help and for this amazing tool.

There are many possible combinations of the parameters in the ghacks article and it is often not clear which settings are the best.

The linked extension allowed for different rules per site. As it wasn't included as addon for the profile generator anyway I just remove the link. I think there are some replacments, but I would need to test them before I can recommend them.
