When I log in to my Apple tv account on the Firefox browser, it comes up, but won't play the selected program. All other streaming services I subscribe to work fine on Firefox, as did Apple tv until this week. If I try running Apple tv on Google chrome on the same lap top, it works fine too. Ditto on my iPhone using Safari. I'd prefer staying on Firefox to stream Apple tv, but can't make it work at the present time. Can you help?

Sometimes I want to enter arbitrary IPA strings into websites from my phone. I've tried finding a privacy-respecting way to conveniently do this and the best way I've found so far is to use the app Unicode Keyboard by Tim Wunderlich, available on the Google Play Store, and enter the code point for the IPA letters or diacritics I want. This works in every other app, but in Firefox, there are two characters I can't enter this way - the combining grave diacritic U+0300 and the combining acute diacritic U+0301. Even other combining diacritica work. I like researching and talking about linguistics and conlanging online, and sometimes this involves using those diacritics to mark tones. This is such an odd specific incapability for Firefox to have but it has persisted, since at least as far back as 2024. I've just had to enter those diacritics in another app and copy&paste them in. I can enter the diacritics directly as keyboard input in Firefox on Windows and GNU/Linux.

Several websites are not loading their content since yesterday. YouTube has a message "Try searching to get started" and even when I open a video, it won't play. X.com is not loading content in the pages. So far it's those two.

Hello Mozilla Support Team, I’m facing an issue while accessing my website https://sreevikash.com/ on Firefox for Android. The site either loads partially or does not render correctly compared to other browsers like Chrome.

Steps to Reproduce:

1. Open Firefox on an Android device
2. Go to https://sreevikash.com/
3. Observe the page layout and loading behavior

Expected Result: The website should load fully with proper layout, images, and styling, similar to other modern browsers.

Actual Result: Some elements do not load correctly, and the layout appears broken or incomplete.

Device Information: Device: Android smartphone OS Version: Android (please specify version if required) Firefox Version: Latest version from Play Store Network: Mobile data / Wi-Fi

Additional Notes: The website works fine on Chrome and desktop browsers. I would appreciate guidance on whether this is a Firefox compatibility issue or something that needs to be fixed on my website.

Thank you for your support.

I even told them that I have no problem logging on to Government Web Sites. Can you help me?

I can't log in yahoo mail on firefox, but I can log in if I change to microsoft edge even if I turn off ad blocker, and add yahoo in exceptions for enhanced tracking protection

I can't sign in to gmail as I used to for years. (It works ok when I use Private Browsing, but that's inconvenient.)

WHAT USED TO HAPPEN: when I was at the sign in page, my password manager (Dashlane) filled in the username and then a screen asking to use the passkey. I said yes, and got in to Google with no problem.

NOW: the password manager fills in my username (my name at gmail.com) and when I hit "NEXT" in the sign in field I get email or phone l.com When I click in the field that disappears and my username appears. When I hit NEXT it goes back to "email or phone l.com". Same when I hit return. Same when I enter my phone number. SO maybe it's Dashlane (my password manager)? But when I disable that and TYPE my username (or phone number) in the field, same stuff happens.

BUT when I use a private browser window, the gmail sign in works as before, and so that's what I've been using -- but it's not convenient having 2 windows open. Before it was just a tab in one window. What changed? Why? Can I change it back? Thanks!

The email address box does not accept the email address and comes up with an error message. The only way to send an email is to use a different browser ie Google. Emails are still received as normal on Firefox / BT mail

When I open mail.yahoo.com, I keep getting: "Something went wrong,We could not sign you in. Try again from a different device." what should I do? any other browser works fine, just firefox is block, I might stop using it very soon.

Hello, I use a shortcut link in my book marks bar to access my apple email account throughout the day on my mac. Apparently my firefox browser was set to auto-update and the new update today has presented some problems. None of my icloud apps are loading either using the updated browser.
