Copilot toolbar button does nothing on Linux
fixed in dev channelWhat's broken: in Microsoft Edge on Linux, the Copilot toolbar button is present but non-functional — clicking it does nothing. The feature works on other platforms, so this is a Linux-specific gap, not a disabled feature.
What we've done: submitted through Edge's built-in feedback system on 23 September 2026 with a screenshot, a screen recording, and a detailed write-up, identifying as a navi maintainer evaluating Edge as a reliable distro browser option. The full submission is logged in our public Edge-on-Linux feedback tracker.
Update — likely root cause: community reports indicate the Linux build ships without the HubApps profile file the Copilot sidebar needs — placing it in ~/.config/microsoft-edge/Default/ restores the sidebar. That reframes this from "button does nothing" to a Linux packaging gap, which is a much more actionable report. The same symptoms are tracked publicly at MicrosoftEdge/DevTools#278 across Mint, NixOS, Fedora, and Arch. We're folding both into our tracker. (We're not shipping the manual file-drop as a fix — downloading an unsigned profile file from a stranger's dotfiles repo is not something a distro should bless.)
Update — fixed in Dev, 11 October 2026: Raven installed Edge Dev to verify, and the Copilot button now works — the sidebar opens and functions normally. Whether our September feedback contributed to the fix is unknown (the Edge team's internal bug notes aren't visible to us), but the timing is suggestive. Stable channel still pending verification, per our own rule: a vendor fix isn't done until it's confirmed on real navi hardware.
What it blocks: nothing we ship — Edge is an evaluated option, not a default. But it matters for the evaluation: a flagship AI feature dead on arrival on Linux is exactly the kind of paper cut that keeps a browser out of a distro's recommendations.
