I'm considering to switch from #ArcBrowser / #ArSearch on Desktop and Mobile to full on #OrionBrowser on all platforms.
Orion is a lot less bloated simply by not relying on Chromium as it's foundation to begin with (it's 100% WebKit while supporting Chrome and Firefox extensions).
From a quick search over at https://orionfeedback.org it seems they have all the features I got to love in Arc Browser including vertical tabs, "little arc" and auto-close tabs and a lot more so that shouldn't be an issue either.
And honestly, zero-telemetry, first class ad-blocking and a #Linux version in the making? Almost sounds too good to be true
