Assuming this email is legit, the best thing that you can do is change as many of your passwords as possible to be unique and complex. You may also want to consider deleting old email addresses and getting new ones. Alternatively you can separate your emails addresses by having one for signing up for spammy services, one for personal stuff, one for work/school, etc. Try not to have much overlap between them all.

Edit: I also highly recommended using a temporary email for signing up for stuff whenever possible. I always use this one , but there are plenty of others too.

I’ve heard of ironfox but it doesn’t look easy to install on Android right now

I wonder if it’ll be added to fdroid or not.

Hm…what’s the best choice to switch to then? I was under the impression that fennec is less private and secure than mull.

Is there no way to spoof that I’m using one of those without actually using them?
