Thankfully i don’t have this problem, almost all of my contacts use only proprietary messengers instead of this shady Signal.

It’s probably private, but sadly not open source.

Tor Browser will give you most privacy and security, but it can be considered overkill for everyday use. Librewolf takes second place.

Isn’t accessing TOR network from any other browser than Tor Browser a serious anonymity risk?

If you want obscure, I can recommend Lagrange. It can browse only gemini pages though, so you can’t visit your favourite html websites.

Sadly, I have no one to use with it, so I don’t know about battery usage. I just like, that it doesn’t require any external identifiers, unlike Signal.

Signal for security standard and ease of use, which is essential, if You want to use it with non techy people.

Simplex for anonymity, You can download it, share chat and start talking without registration.

You can combine search engine of choice with anonymity provided by TOR browser.

Number of bits can also depend on your UI scaling, resolution and timezone.

They probably give entropy value, average number of, yes or no, questions that are needed to identify You. (Guess all the information that your browser provided)

After disabling extension “I still don’t care about cookies” on Librewolf, I went from 17.48 bits unique fingerprint to 16.48 nearly unique one.

Their loss.

So how can Signal send verifying sms?

Perfect is the enemy of good.

It’s better to have partial privacy, than no privacy at all. So keep using GOS.

In my country popular free email providers send many spam messages to users by themselves, so inbox looks much worse than in gmail.
