    1. Vivaldi is extremely customizable, presenting a wide range of settings and built-in features designed to put the user in control. Its Chromium-based engine makes it fast and compatible with most Chrome extensions, and Vivaldi removes the code that tracks users from it.

      architsastam Vivaldi is simply the next stop for Firefox users, while it is freeware, it is technically closed and open-source. Some of the browser's components are closed while some are open and the source codes are available on Vivaldi's website.

      It's very laggy to open some pages, on Linux, it's hard to install and often lacks basic codecs, so videos on youtube looks pixelated!

      User1639378 Not a real alternative firefox is an opensource standalone browser. vivaldi is based on chromium and only provides a proprietary UI for the chromium core. You cant also disable telemetry in vivaldi due to their business model.

      josephcw Vivaldi is very fast and has unusual features. Unfortunately, it's not open-source, so I can't recommend it over Firefox.

      When Firefox become more and more bloated Pale Moon is lightweight, offers stability and compatibility with the FF extensions (for now, because WebExtensions). It also works great with a lot of tabs(400 or more).

      So far, Pale Moon gives me features I want that Firefox has disabled and will soon be gone completely in Firefox 57. Firefox 57 will be a Chrome-like boat anchor. Pale Moon is very stable, lightweight and is fast

      Their privacy claims go as far as Facebook saying "we don't sell your data". You are tracked by cryptocurrency companies (Uphold & Brave rewards), they can ask for ID card as well. In the end this is just Chromium with a build-in ponzi scheme; slower and less private too.

      JohnFastman It depends what you want from a Firefox alternative. Waterfox is essentially identical to Firefox, except that it's a 64-bit, not a 32-bit browser. It's still open source and fully compatible with all options, extensions and everything else.

      Chromium vs Mozilla Firefox opinions
      Almost everyone thinks Chromium is a great alternative to Mozilla Firefox.
      JohnFastman Chromium is the core of the Chrome browser. It functions well enough as a browser but lacks some of Chrome's features (e.g. built in language translator). Even though Chromium is open source, it still "phones home" to Google, which has privacy implications. There are more private Chromium-based browsers, such as Brave and Iridium.

      Different from Firefox, it doesn't autoupdate on Windows. You need to basically download a new browser per wiki and install... On Linux, it's more easy to manage updates depending on the distros, on Arch Linux/Debian it's so easy, but hard on Ubuntu/Mint.

      Chromium doesn't have DRM features and some codecs implemented like Google Chrome, it's open-source but all your data goes to Google when you use Chrome Store to download apps since there is no Chromium store. Also, this browser is hard to install on Windows, you have to compile or download versions that are created by the users daily, so it means you do not have a proper installer like on Linux/BSD.
