Some tests only fail in Firefox

[SammyIsConfused]

Describe the bug
On Chrome, the suite will run both on the CodeBuild server AND locally and pass all tests.


On Firefox, the same is not true. There are currently 14 failed tests and 3 skipped tests when using Firefox.

To Reproduce

1. Run the TestNG OldTests suite using Chromedriver for Chrome in headless mode.
2. Note that the results show a full pass.
3. Run the TestNG OldTests suite using Geckodriver for Firefox in headless mode.
4. Note that the results differ from the Chromedriver results.

Expected behavior
The tests should be consistent with one another, and should always have the same set of failed tasks.

Platform:

• OpenEquella Version: 2019.1
• OS: Ubuntu 18.04
• Browser: Chrome, Firefox
