Strongly recommend #TorBrowser w highest Safety level and #uBlock added, as per how #TailOS provide Tor to #journalists. Great for browsing the #clearnet and onion sites. Put the #NoScript addon button in the topbar to easy enable js for trusted sites.
For #I2P we recommend a #Firefox based browser that is hardened like TorBrowser. A good place to start is the spyware.neocities.org site, and the #ArchlinuxWiki on #hardening Firefox-based browsers.
