      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

      Not secure at all, based on Chromium as 99% of the browsers. It doesn't get my respect. No differencial, just Chromium + some extensions implemented.

      Ola It's great with a browser that is trying to solve the issue with ads on the web AND the issue that publishers needs money to build cool sites.

      JohnFastman Currently (March 2017), Brave is not a mature project. It's an open-source privacy-oriented browser and very fast. But you rely on the developers to provide most of the privacy settings, and you can't install extensions. Firefox remains much more customizable via it's about:config menu options.

      Akino Waterfox is made for x64 (amd64) CPUs, and it also delivers you a fine service concerning privacy, firstly devs removed telemetry and tracking implented recently in Firefox. Secondly it supports old extensions and pocket was removed

      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.

      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.
      Positive comment about 4 years ago 42 users agree and 18 don't

      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.

      SiliconeValley Chromium is most likely the heart of Google Chrome, Opera and some browsers without fancy features.

      JohnFastman Despite Chromium being "open source", it still downloads Google-related crap and phones home to Google. If you value your online privacy, you'll appreciate the Ungoogled Chromium browser, which removes all that. However, Firefox remains more customizable in terms of privacy options.

      1. It doesn't update like Chromium 2. It's hard to install on Windows and Linux 3. There is no DRM support, so forget about watching Netflix on it 4. It's hard to install extensions, no access to Google Web Store. 5. No Widevine codec available and to install it is hard and need manual intervention that doesn't work always.
      Negative comment 8 months ago 3 users agree and 5 don't

      Google services do not work properly on this browser, no DRM support of proprietary codecs available. Also, on Windows there is no .exe to click and install you need to compile and build it, it's not that simple and pretty limited in customization, even more than proper Google Chrome.
