Opera Rethinks What a Browser In 2017 Should Do: Adds Quick Access To WhatsApp, Telegram, Messenger in v45 (theverge.com)
Opera says it has been working on a complete redesign of its desktop browser for a few months. Codenamed "Reborn", the new version of the browser focuses on one feature that it thinks many people desire in 2017: a way to stay connected with friends and be able to swiftly share things. The Verge adds: The latest addition is a messaging sidebar built directly into the browser interface. From the sidebar, users can log into their WhatsApp, Facebook Messenger, and Telegram accounts, and chat with friends and family without ever leaving Opera itself. [...] But as with previous updates, there's a lingering feeling that this new feature is a little bit too superficial. While it is nice to have access to chat apps in the browser window, their inclusion makes for a crowded interface.
Try this:
1. Install Firefox (desktop).
2. Open Firefox and run a Slashdot browsing session.
3. Look at Firefox's memory use.
4. In about:config, set privacy.trackingprotection.enabled to true. This enables Firefox's built-in tracking blocker. In practice, it behaves as an ad blocker because most sites neglect to replace tracking-based elements that fail to load with ads that don't track the user.
5. Restart Firefox and run a comparable Slashdot browsing session.
6. Look at Firefox's memory use. See how much memory was wasted on tracking the user.
