    Firefox got better with performance improvement. But still no translation engine built-in and in compact able sites are my only concern with it. Memory footprint is almost the same on 64bit version.

    I would love to get Brave, but the only reason I will not let this thing on my computer, is because of the fact it is apart of the Chromium Project. However, I'm not gonna make this a negative comment because it is actually very fast, and is a decent browser

    pure garbage. has very little to do with developers, super heavy, a lot of the "developer" stuff are dated almost 10 years ago and pretty useless,
    you can have it all with the nightly version at https://ftp.mozilla.org/pub/firefox/nightly/latest-mozilla-central-l10n

    its icon is cool,
    but that's about it.
    you can not do extra stuff with web-extensions.
