This is related to `trackingprotection` breakage #1101005

Looking at the devtools console, here are the blocked resources:
The resource at “https://assets.adobedtm.com/fd235021841d59990748b6f77f451cc2db6649ad/satelliteLib-2d346812c55dcf490db0ee6bb3d7c77351023f45.js” was blocked because content blocking is enabled.[Learn More] contattami

So these are the domains to test:
​assets.adobedtm.com

I opened the URL in a fresh browser profile (Firefox Nightly 66, uMatrix installed, normal mode) and loaded the page. After the login I selected a drop down menu box and the menu options were not available,

I disabled the Spoof Referrer option in uMatrix and then *WHITELISTED*:

​assets.adobedtm.com

After this, the drop down menu options were displayed.
The other resources didn't help.

adobetm.com can be found in disconnect-blacklist.json list.

So in conclusion:
adobetm.com - Analytics = [tp-analytics]

Does this still reproduce, Ciprian? I was able to fill out the "log in without registering" form, but was never sent a confirmation email. I don't think I saw adobetm requests being blocked.

I experience the same issue as you did, Tom.

I tried to proceed without registering but I did not receive any confirmation email.

When I initially filed the issue I was able to create a tourist account, but in the meantime, it looks that some things have changed and I am not able to find the option to log in using a tourist account.

Alright, thanks. I'm going to leave this open for now since we can't quite confirm whether it's still a problem.

The layout has changed and we are not able to create a tourist account anymore, thus unable to verify the issue.

I found some drop-down menus on a page and they work correctly with ETP - Standard/Strict.

Tested with:
Browser / Version: Firefox Nightly 87.0a1 (2021-02-16)
Operating System: Windows 10 Pro

I'll close the issue.
