Thanks for the screenshot!

Yes, that menu looks thin when compared to Android. see screenshot Let me go install Firefox on my wife 15Pro and I'll post a screenshot.

Here is what I see on iPhone 15Pro. see screenshot Looks like you need to click on the option that says "Enter your password to connect".

FYI... There is a bug with IOS. Firefox for iOS login deletion https://bugzilla.mozilla.org/show_bug.cgi?id=1872730

Thanks for trying to help. I don't understand how to fix a bug.

Not asking you to fix the bug, just an FYI. Did you click on where it says "Enter your password to connect"?

Thanks for your continued assistance! I'm so frustrated that I'm having these problems. Yes, I have clicked on "Enter your password to connect." I note that there is an exclamation mark "!" in a triangle superimposed on the menu in the bottom right corner. That triangle appears again on the command line "Enter your password to connect when the menu is opened. The command line takes me to the page "Sign in with your camera." Two options appear. 1) "Ready to scan." I open my PC to Firefox.com/pair. I confirm that I have Firefox for mobile. I'm taken to the page "Sync Firefox on your phone or tablet," where I'm asked to tap "Sync and Save Data," in the Firefox menu. I don't have that command in my menu! 2) This option is "Use email instead." I click this, which takes me to a page that asks me to "enter your password." I enter the password and click "Sign in" The dark blue sign in box turns light blue and then just spins and spins. Two dead ends. Any suggestions?

Interesting.... Forget that pair option. Just keep it simple and sign into the account. Would you or someone in family have another phone or an Android to test with. Not a Apple fan, but let me go try it on my wife's 15Pro and see what happens.

It worked me. see screenshot

In the browser, can you log into your account? https://accounts.firefox.com

Yes, I can login to my account. Seems like I'm already logged in; I didn't need to enter a password.

Have you tried the good old uninstall and reinstall trick?

If I reinstall, will my settings bookmarks be saved?

Your data is on your computer right? The issue is the phone, so reinstall on the phone not the computer.
