I've encountered an issue where my website [http://example.com undertale es] doesn't seem to be functioning properly on Mozilla Firefox. It works fine on other browsers, but I'm noticing [specific issues you're facing, e.g., layout problems, functionality not working, etc.]. I'd appreciate any insights or guidance on how to troubleshoot and resolve this compatibility issue with Mozilla Firefox. Are there common compatibility issues I should be aware of, or is there a specific debugging process I can follow? Thanks in advance for your help!
