After Firefox updated, I can no longer access www.apple.com. This is the error I get now:

Blocked by X-Frame-Options Policy

An error occurred during a connection to idmsa.apple.com.

Firefox prevented this page from loading in this context because the page has an X-Frame-Options policy that disallows it.

Can anyone tell me how to fix this issue as soon as possible. Thank You.

Hi firefox2017, I don't see a problem with displaying the calendar or using event links. It seems your user is signing in to a Google account in the frame, judging from the address "accounts.google.com" in the error message. I don't know why that would be necessary -- "copy to my calendar" or "Add to Calendar" should launch in a new tab and not go to a login page inside the frame. If those are opening inside the frame for the user, a setting might have been modified or an add-on might be suppressing the new tab?

All except one (as far as I know) has no problem with it. As said, the same effect is observed in FF safe mode so no add-ons active. I'm not sure (will ask him) if he even has a Google account as he's a complete noob about computers (and about 80yo.)

I have a few Google accounts but I remain logged out except when needed, I also don't have any rights for the calendar (I'm a regular user as far as that's concerned).

The only settings I'm aware of in his Firefox is tracking blocking and 3rd party blocking (the same as my settings, that was the first thing I checked) I'm using adblock, ghostery, noscript ..... and have no problems. For now he uses Chrome to see the calendar but because of corona no activities are held, so no reason to use the calendar for now :-)

Hi folks, I'm a Firefox engineer and we're actively looking into this issue, but unfortunately we're having trouble reproducing almost all of the reported breakages. We need more information and want to ask for your help. We have prepared a few detailed questions, feel free to post answers here or send them to me privately via email (jhofmann at mozilla dot com).
  • What page(s) are you visiting when encountering the problem?
  • Is this issue permanently reproducible for you? i.e. if you reload the page and try it a few times, does it always happen?
  • Does this issue reproduce on a clean profile (you can find instructions on how to create a new temporary profile here)?
  • Can you please send us your about:support information (go to about:support and click "Copy raw data to clipboard")? Particularly, it is interesting to us which extensions you have installed and how your tracking protections are set up.
This would help us a lot in tracking this down! Thank you!

  • Issue is permanently reproducible (occurs after multiple refreshes, on a fresh profile, and even on different browsers).

I have this problem as well: "Blocked by X-Frame-Options Policy". A solution that worked for me was to open the link in a new tab (Ctrl+klick).
