Tangram is a browser for your pinned tabs. What this means is that I can put all my frequently visited websites in an app and have the ability to view them all with great ease. Before I was signing into everything each time I needed to check it but now I just switch to my workspace that has tangram open. I use mine for email, discord, and matrix. As a tab hoarder it’s also quite nice in how it clears up many of my tabs.
Oh man this sounds like a security and privacy risk
Why? No more so than a normal browser.
It’s good to setup your browser to delete everything when you close it. And to use containers in Firefox that isolate some dangerous websites like Google or Facebook in a silo.
