Yes but...

• Most people want a quick-fix.... "just install these extensions and all your web privacy issues will be handled automatically, in the background and you don't ever have to do anything at all." The "no user effort required" approach isn't realistic and arkenfox is not a quick-fix. It's a lot of tough love imo.
• To use arkenfox and also not get frustrated that the entire internet is broken you will need to create a good user-overrides.js file. Creating a good one takes time. So take it and create a good one.
• RFP breaks a lot of things. If you choose to disable RFP, the arkenfox wiki suggests you use the anti-fingerprinting extension, CanvasBlocker.
• If you use arkenfox's user.js you'll probably want to create multiple profiles with different levels of arkenfox strength, which can be determined by your user-overrides.js file.

I mostly use arkenfox... but I also have a TCP + uBO only profile for when I need it.

I don't have that option. How are you running Sonarr? Docker? What image are you using? I'll download whatever you're using. I'm on a linuxserver.io Docker image.

Can you describe what you’re talking about? I’m not sure I’m doing that either.

I’d absolutely recommend using your own modem and router. I do it and the additional control over your network is more than enough reason to make the switch. Plus, using your own modem, and router usually pays for itself in two years, so there are financial benefits as well.

You will need to make sure you get the right modem for your ISP. You can usually verify which one you need on their website.

I found the binary for the sid repo. That worked. Here is the link in case someone does a search: http://ftp.de.debian.org/debian/pool/main/f/firefox/
