Fix Copilot (Missing HubApps File)

The HubApps file tells Edge which sidebar apps to load — Copilot being the primary one.

Edge on Linux ships without a required configuration file called HubApps. Without it, the Copilot sidebar will not appear. Adding the HubApps file returns the sidebar functionality.

• Download the HubApps file.

  You can copy it from a Windows Edge installation at: AppData\Local\Microsoft\Edge\User Data\Default\HubApps

  Alternatively, download the community-maintained copy here and extract the HubApps file.

• Create the target directory if it does not already exist:

  mkdir -p ~/.var/app/com.microsoft.Edge/config/microsoft-edge/Default/

• Copy the file to ~/.var/app/com.microsoft.Edge/config/microsoft-edge/Default

  cp HubApps ~/.var/app/com.microsoft.Edge/config/microsoft-edge/Default/HubApps

• Restart Edge. Copilot should now appear in the sidebar.

Fine-Grained Flag Editing

Many flags that are compatible on linux cannot be found on edge:flags, but we can still edit them via a flag file.

• Edit the flag file

  nano ~/.var/app/com.microsoft.Edge/config/edge-flags.conf

• Example flags

  ~/.var/app/com.microsoft.Edge/config/edge-flags.conf

  --disable-features=ElasticOverscroll

• Ctrl+O → Enter → Ctrl+X to save file and exit

• Restart Edge to apply the flag.

Fix Web App Icons on Wayland

When you install websites as web apps from Edge, their taskbar icons may not appear correctly on Wayland. This happens because the .desktop files generated by Edge use an outdated StartupWMClass format that Wayland compositors do not recognise.

The fix updates all affected .desktop files to use the correct format.

Before	After
StartupWMClass=crx__APPID-PROFILE	StartupWMClass=msedge-_APPID-PROFILE
StartupWMClass=crx__eigpmdhekjlgjgcppnanaanbdmnlnagl-Default	StartupWMClass=msedge-_eigpmdhekjlgjgcppnanaanbdmnlnagl-Default

It is suggested to use VSCode to create a local git repository in ~/.local/share/applications to track changes and make edits.
