I use both Firefox and Librewolf to achieve browser isolation. Librewolf is my default browser for all anonymous browsing such as news sites. I use Firefox for all my real name ID account logins such as banking. This way your Librewolf browser fingerprint is never associated to your real ID.

Yeah, I get the concept of using different browsers for different things to compartmentalize, and I've tried it, but to me it just seems like I'm making my life more complicated switching back and forth, and I feel like it's cluttering up my system. I love how Librewolf takes privacy to another level, but honestly, all I want is Firefox without all the BS and the ability to disable things I don't want (and not having them turned back on).

This is one of those trade-offs between convenience and privacy I have internalized over years. You can refer to this guide to configure Firefox to be more private. https://www.privacyguides.org/en/desktop-browsers/#firefox

A custom user.js will do the job

It used to be really easy to search about:config for 'http' and just delete all URL's to quiet things down. More recently the about:config search only searches attributes not values so you have to "show all" and it's quite tedious to find them all. Even then there are some things you have to block with a hosts file entry.

That said it is possible to have firefox start cleanly with absolutely no network traffic except for sites you visit.

Browser isolation is smart, and Firefox+Librewolf is better than Firefox+somethingelse.

Don't forget about Firefox profiles though. You can have unlimited, 100% isolated browsers with profiles. I use a few dozen Firefox profiles.

For isolation of cookies but not preferences, you can use Multi-Account Containers within a single Firefox profile. I use this for admin-vs-user accounts at AWS, GitHub, etc.

I still think it's better to use Firefox containers on either of these browser, and combine them with temporary containers to isolate different aspects of your online life. By default all browser sessions are ephemeral, so no cookies are stored, just like incognito mode. Only when you whitelist a site to use a named container do they gain the ability to use your local storage. Using different containers appear to change fingerprints, it seems.
