Hello,

Thank you for reaching out to the Firefox Support Forum with your issue. I understand that you are experiencing difficulties accessing a local server site on Home Assistant after a recent update to Firefox.

Based on the information you provided, it seems that the issue is specific to Firefox, as you mentioned that you can access the site without any problems using Chrome. Since you have already tried uninstalling and reinstalling Firefox, as well as Home Assistant, without success, there might be some compatibility or configuration issue with the recent Firefox update.

To assist you further, I would recommend the following steps:

Clear Firefox cache: Go to the Firefox menu, select "Preferences" (or "Options" on Windows), navigate to the "Privacy & Security" tab, and under the "Cookies and Site Data" section, click on the "Clear Data" button. Make sure to select both "Cookies and Site Data" and "Cached Web Content," then click "Clear."

Disable Firefox extensions: Some extensions or add-ons can interfere with website functionality. Try disabling any extensions you have installed in Firefox and see if the issue persists. You can do this by going to the Firefox menu, selecting "Add-ons" (or "Extensions" on Windows), and disabling all extensions temporarily.

Try Firefox in Safe Mode: Safe Mode disables all extensions and uses the default theme, which can help identify if an extension or theme is causing the problem. To start Firefox in Safe Mode, go to the Firefox menu, select "Help," then "Restart with Add-ons Disabled." If the issue doesn't occur in Safe Mode, it indicates that one of your extensions or themes is causing the problem.

Check Firefox proxy settings: Incorrect proxy settings can prevent proper access to local sites. To check your proxy settings in Firefox, go to the Firefox menu, select "Preferences" (or "Options" on Windows), navigate to the "General" tab, scroll down to the "Network Settings" section, and click on the "Settings" button. Ensure that the "No proxy" option is selected unless you have specific proxy requirements.

If the issue persists after trying these steps, I would recommend posting your question on the Firefox Support Forum. Include the details you provided here, and the community will be able to assist you further with troubleshooting and resolving the issue.

I hope this helps, and please let me know if you have any further questions or concerns.

Best regards, Firefox Support Volunteer

I tried all of the suggestions and nothing worked. I still have the same problem.
