## Example setup for Firefox

The solution is to setup proper `.desktop` file name for windows of these apps.

1. Find the proper name of Firefox `.desktop` file:

```
$ find ~ -iname *firefox*.desktop

~/.local/share/applications/firefox_firefox.desktop
```

2. Setup KDE window rule.

Open **System Settings** -> **Window Management** -> **Window Rules**.

Click **+ Add New...** and set the parameters:
* **Window class (application)** -> **Exact Match**, enter `firefox`
* **Match whole window class** -> `Yes`
* Click **+ Add Property...** -> Select **Desktop file name** and enter name of `.desktop` file, e.g. `firefox_firefox.desktop` in the example above.

**Alternatvelly** one can use the [WaylandDesktopFile.kwinrule](WaylandDesktopFile.kwinrule) file provided. In the **Window Rules** dialog click **Import...** and set the actual `.desktop` file name afterwards.
