## System
* Version: 0.19.1
* Platform: Windows 10
* Firefox: 57.0
* Seleniu…m: 3.7.1 (Java)
## Testcase
1. Set up Selenium hub + node
2. Prepare Firefox profile on the node (optionally install an extension)
3. Create a browser on the grid with passing in the args to load the profile from local file system:
```
FirefoxOptions fo = new FirefoxOptions();
fo.addArguments("-profile", "./firefoxprofile");
DesiredCapabilities c = DesiredCapabilities.firefox();
c.setCapability(FirefoxOptions.FIREFOX_OPTIONS, fo);
RemoteWebDriver wd = new RemoteWebDriver(hubUrl, c);
```
### Expected result
1. Browser opened
2. Profile is loaded from the node's local file system
3. Session is created
4. Browser can be interacted with using the RemoteWebDriver object from the tests
### Actual result
1. Browser opened
2. Profile is loaded from the node's local file system
3. RemoteWebDriver.createSession() never returns, session is not created
### Notes
- The Firefox profile was created on the same node, with the same version of Firefox
- There is only one extension installed, but I tried it without that, same result
- Starting Firefox through selenium grid works as expected without `fo.addArguments("-profile", "./firefoxprofile");`
- Firefox does not hang when started, it can be interacted with manually.
- Launching Firefox with `firefox.exe -profile "path/to/profile"` also works.
