Browsers

Chrome is the best choice because of several reasons: Extensions, Devtools, browser-accounts.

Firefox Developer Edition also has its perks.

Opera browser runs on the same engine as Chrome so you can use chrome extensions once you set up this extension: https://addons.opera.com/en-gb/extensions/details/install-chrome-extensions/

Notable extensions are:

1. Wappalyzer

2. Google Keep

3. New Tab extensions- Tabbie 500px New Tab

4. JSONView This extension is in maintenance - https://github.com/sloanlance/JSONView-for-Chrome/issues/1

Best practices to employ: Use bookmarks, Open as few tabs as possible to save on RAM. Or use Tab suspenders extension for this.
