There is a solution, but don't use it, use mastodon:
In the settings, enable Firefox containers. This allows you to seperate the cookies of X from all other sites. Also install uBlockOrigin to block all trackers on X itself.
Mastodon doesn't have a fraction of the ground sources that Twitter has. You go to Twitter because that's where the people who know shit and tell you about shit are. It has nothing to do with Twitter itself. It's just network effects.
I get why you're annoyed at Twitter (Elon) - I am too, and I still call it Twitter - but there just doesn't exist anything like Twitter. It's the only place where you can ask CEOs and CTOs questions directly. Where you can learn about what is actually happening on the ground in Ukraine from first hand reports from people who are there. Where you hear subject matter experts debating strongly in favor and against all matter of topics. It's sad that it's the only place like it, but it is.
I've disliked Twitter since way before Elon acquired it. And I actually really like Elon as a person, even if I disagree with a lot of things that he's doing with Twitter, because I didn't really care about Twitter to begin with.
Fundamentally, what I don't like about Twitter is the low signal-to-noise ratio. Even if you try to curate the people you follow, Twitter will find a way to push useless stuff in front of you, and even the people who post interesting stuff tend to post pointless stuff from time to time because of the prevailing culture in Twitter.
And I also don't assign a lot of value to accessing ground sources in real time. If anything, I think people care too much about being up to date on everything.
