Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Modern look
It is a very modern version of Opera. It looks like a desktop app instead of a web browser.
Pro Futuristic interface
Opera Neon innovates with its clean aesthetic pleasing interface.
Pro Access to new features
Nightly comes after beta which means you get access to more features.
Pro Blazing fast
Short load times. Quick tab switching. Fast rendering.
Pro Private and secure
Made with privacy and security in mind, even Tor based their browser on it.
Cons
Con Owned by Chinese Consortium
Pretends to be a Norwegian company, but is actually a Chinese company. Opera does not respect user privacy and is not trustworthy!
Con Not meant for general use
This browser is not meant for general use. It only exists, because the Opera developers had some ideas for the user-interface, and wanted their users' feedback. If you want a browser that you can use day-to-day, something with bookmarks and security updates, look elsewhere.
Con Bad UX
The usability is not the best since the left and right bar take up space and there is no way to resize them.
Con Never updated
The Opera folks came out with a browser as an experiment - and then they essentially abandoned it. It really was great, but since they never planned to support/update it and it's closed-source, it's not recommended.
Con No Adblock
There is no Adblocker like in the original Opera.
Con No extension support
Due to the way the browser is built, it does not support Chrome extensions even though it is Chromium based. Opera extensions are not supported either.
Con Buggy; performance issues and crashes
Because you're accessing new Firefox features, bugs and crashing comes. Firefox Nightly is meant for developers and it's for PCs that have low chance of getting attacked. If Firefox is for you, go for the normal one or beta at least. If you use Nightly, checking updates regularly is recommended.
Con The icon is ugly
Con Not intended for general use
This browser was made for testing purposes for future versions of Firefox, and it can easily crash. Most people should use the stable release of Firefox.
