Description

After upgrading from FF 115 esr to 128 esr every login attempt to my paypal account requires SMS authentification, although the device should be remembered. Deleting all cookies/storage and removing the "known devices" and going through the "you are logging in from a new device, remember it?" dialog of paypal, it won't work. But when I am on the "SMS authentification required" page (after entering my password) and disable uBlock, then go back and enter my password again, I'm getting in without the SMS dialog. So, whenever enabling uBlock, I'm asked for the SMS authentification, whenever I disable it, I get in.

It seems that with FF 128 uBlock is blocking something that Firefox tries to send so that paypal can identify the device as known. Maybe uBlock considers this as tracking information or sth. and therefore blocks it.

I can workaround it by disabling uBlock, but in case you would like to figure out what this piece of data is that uBlock falsely blocks, let me know if I can help debugging it.
