Sometimes its needed to search the net anonymously and/or without region code. Plus, there are other issues on hiding/showing data about oneself, friends, and projects on the Computer/Device. A summary of what came through me:
Surfing / Browsing:
TorBrowser surf the web anonymously / anonym; all systems/devices. [I use it]
ZenMate Firefox-Plugin, hide country, anonymously / anonym? [I use it]
ProxTube Firefox-Plugin, hide country, (anonymously / anonym?) – pretty slow, double loads pages, sometimes didn’t work [I use/d it]
RequestPolicy recommended to be showing links to totally different domains than one thinks to view / feed, and one can block that [right? Please comment, I didn’t use it yet]
eMails Sending / Receiving:
The Mutt E-Mail Client is called to be working well with GnuPG, and without HTML; operating on „Unix-Systems“ which Mac OSX appears also to be..
Messages/Groups / Nachrichten/Kontakte:
Threema / Suisse/Schweiz better, saver, and pretty cheap (~1€ ?) ?
OSX 10.10 Spotlight – loads even Spam-Mail-Links; heise-workaround… [installed it + QLStephen, too; not restarted yet ;]]
