show details not working anymore in Firefox

prog · 12 Nov 2022, 02:20 AM

Hi,
I've been having issues recently with Fastmail and Firefox.
When I click on the Show Details drop down to view the recipient email address (and other special fields), it changes to Hide Details but nothing happens or is shown below like it used to do.
I tried with two different computers to make sure and it's the same thing.
But it's still working in Chrome. Is anyone else having this issue?
Is there a reason / explanation / workaround or is that a new bug I should report?
Thank you!

Same thing here on Linux 20.3 running FF 106.0.5.

Did some testing and found that it's the Facebook Container add-on. Disable it and Details works. Enable it and it doesn't work. My add-on shows version 2.3.9 last updated Nov. 4.

I can confirm that disabling this add-on solved the problem for me as well.

Thank you very much!

I opened a support ticket on this with Fastmail.

Support replied that the problem is in fact with the Firefox Facebook Container add-on and that they had contacted Mozilla on this.

Meanwhile a workaround is to use the Firefox Multi-Account Containers add-on and force it to always open Facebook in it's own container. Details here https://support.mozilla.org/en-US/kb...ti-account-con

Update: Received an email from FM today saying the issue has been resolved on their side. You need to re-enable Facebook Container shut down Firefox and re-start.
