Couldn't get email from archive.org.

An extension from Mozilla for Firefox that does not work on Firefox. Sad, but unfortunately unable to use it even once, even after restart and similar trials.

It is impossible to join to Firefox Relay Premium from Ukraine - Stripe blocks payment either from card or PayPal. Ridiculous

No option to change the email address to forward emails to.
No option to get a generated alias address using the extension UI or with the right click.
Do not misinterpret me, the right click can only generate, not enter previously generated addresses.

I've used relay since it's launched. I enjoy it and feel it's safer than using something like 10 Minute Mail. The only issue I have with the extension is that would like the ability to see my aliases by clicking the extension rather than having to navigate to the page every time. Though, now that they added ability to add any new alias using a custom domain, I don't really need to worry about remembering a random email address anymore.
