I find it difficult to understand what you are on about - Firefox is a browser, not a bank, and I find it hard to believe some financial scam is being foisted by mozilla. I'd suggest you find a lawyer to handle things and report any such nonsense to the legal authorities. Nothing of what you have posted here is credible.

People are posting fake wallet extensions on the Add-ons site. I think they are posting an innocuous extension first, then replacing its with malicious code during an update since updates for most extensions are reviewed by software rather than by humans. Make sure to ONLY install wallets using links from the official site, and not by searching on the Add-ons site.

Now... if you removed extensions and they came back, that might be caused by a problem with Sync, or there might be some other process on your computer that reinstalled them. If you use Sync, you can turn off extension sync to see whether that allows you to remove them and have them stay removed. See: How do I choose what information to sync on Firefox?

Thanks jscher, but let me ask you, if you search on Firefox extensions for Trust Wallet, do you see any of them? If then you install them (I saw two a while ago) and tell them to create a wallet, do they try to get you to import your information instead of giving you a recovery phrase as they did to me?

I see 3 extensions named Trust Wallet. I am not going to install any of them:

It doesn't look like there is an official Firefox extension, so that leaves the door open to miscreants:

jscher, I see your point. One of these stole my money (my fault, stupid). Anyway I agree with you that these are miscreants. I will have to learn to be more careful finding these extensions. Thanks for the link.
