## The problem
Issue SeleniumHQ/selenium#12495 (closed, 44 comments): ### What happened?
When trying to run my test scripts on a Jenkins using Linux container for Firefox and Edge browsers I get he errors ad shown in the logs. This seems run fine on Local Windows machine.
Note: Also the container does not have Edge and Firefox pre installed.
### How can we reproduce the issue?
```shell
Basic test to launch Firefox and Edge browser and launch a URL
this.browser = new EdgeDriver();
this.browser = new FirefoxDriver();
```
### Relevant log output
```shell
Error while running the test:
Edge:
org.openqa.selenium.SessionNotCreatedException: Could not start...
## What to do
If Selenium can't launch Firefox or Edge in a Linux container, check how the browser binary is installed: the maintainer found Selenium Manager was resolving the /snap/bin/firefox symlink to /usr/bin/snap, which can't report a Firefox version. The fix was to stop resolving symlinks for browsers found in PATH, shipped in the next Selenium version. If your container installs browsers via snap, make sure Selenium Manager finds the real binary, or upgrade Selenium past that fix.
