Not really the same thing, but Revolut has disposable virtual cards that you can use (but it's a full-fledged bank).
Some apps like MBWay in Portugal also allow you to create these virtual cards, but it requires a Portuguese bank account.

I thought it was a problem with my phone since I'm using a custom ROM and it did not happen before. When I open Firefox and it has been in the background for a while, it shows a black screen where the web content should be and often crashes if you try to open another tab or do something else. Also happens if I open a link from another app. The only solution is to close Firefox and swipe it off the recent apps and reopen it. Is this the same problem you have?
While the disposable cards might not always work, you can always create a regular virtual card and delete/freeze it afterwards. Not sure if there are any limits tho
