I’ve been using email aliases for a few years now, but all spam I get is addressed to my main email (which admittedly is readily available on my website). Seems like no one has sold my email address yet

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

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?

Seems to still be available on F-Droid, but the last update was in 2017. I’ve installed it, but ended up not logging in since it’s targeting an SDK version so old that Android is giving me a bunch of warnings (and it doesn’t even scale to my entire screen, there’s a big black space at the bottom)

I’ve had this “problem” before, and I did not want to use the full Messenger app for privacy reasons as well. I had installed Messenger Lite, but it was discontinued a few weeks ago. I now have Facebook Lite, which also has Messenger, and you get notifications as well. It’s not perfect, but don’t give it too many permissions and you should be mostly fine. Using it in the browser is absolutely terrible, and you would not get push notifications.
