A web browser engine used in many modern browsers, all fairly similar.
The closed-source version of the Chromium project. Chrome is making changes that seem likely to sap autonomy and give advertisers your data, and it does suspicious user tracking. On the other hand, it has some cool extensions that I like to use and is a dominant standard.
Chrome is sometime (but not always) subject to the same odd emoji quirk as Brave, below.
Left field entrant, hyped upstart Brave attempts to block the conventional ad economy and privacy nonsense and replace it with cryptocurrency-backed privacy-compatible advertising. It seems to be largely Google Chrome compatible, supporting most of the same plugins etc. It claims blocking the tracking economy overhead makes it faster. Using it is smooth so far.
Weird quirk: on linux after each upgrade the emoji break in subtly different ways. Sometimes it helps to reinstall color emoji
sudo apt-get reinstall fonts-noto-color-emoji
Sometimes it helps to remove the outdated Unicode 9.0 symbola font
sudo apt-get remove font-symbola
Some XML config may make the problem go away.
Backspace for backspace not back-one-page
In Chrome AFAICT this is no longer a problem. They disabled backspace navigation since it appears to be causing frequent data loss relative to intentional use. There is an extension to disable the shortcut if you are on an old version of Chrome.
Various privacy-related tweaks are advisable. See browsing confidentially.
Chrome magically supports the search option on almost any site that searches via the tab to search feature.
