It seems that you are encountering a specific error message when attempting to log in to Firefox on your iPhone. The error message states "missing parameter: client is." This issue appears to be related to the login process when only entering your password without re-entering your email.

Although the error message is displayed, you mention that you are still logged in, and you receive an email notification confirming your successful sign-in. Additionally, when navigating back to the account page, you find yourself still logged in without any further issues.

While this error message might be confusing, it seems to be a minor glitch or inconsistency in the login flow of the Firefox app on your iPhone. It is possible that there is an issue with the app's handling of the login parameters.

To avoid seeing this error message, it is recommended to continue entering both your email and password when logging in. By re-entering both pieces of information, you are ensuring that all required parameters are provided, resulting in a smooth login experience without encountering the error.

However, if this error persists or if it becomes disruptive to your overall user experience, it would be advisable to contact Firefox support or seek assistance from their official forums or online communities. They will be able to provide you with more specific guidance and troubleshoot the issue further to determine the root cause and potential resolutions.

Thank you for the information! I see this issue is only on my Firefox browser when I try to sign in to pocket or other apps using Firefox account I don’t face this and yes I only faced thsi when I key in my password only if I use both email and password I don’t. I faced this on both my iPad and iPhone. Can I check how do I contact Firefox?
