Diễn đàn hỗ trợ Firefox

I'm not sure if I picked the right topic but am guessing my problem would fall under settings. The last few days I am having a problem replying to emails; when I go to click "send" to reply I get an error and it says failed to send. The only way to send a reply back is to compose a new email with my reply in it; send works every time if I do it that way. Hoping someone has the answer to why this is happening because I have no clue where to start.

Thank you for any tips, ~ Kathleen

thank you for your time & expertise:) Can you please help me understand what would happen if firefox stops supporting windows 7 users. Will i still be able to use the browser - just with less security? I will probably have to give up using a computer if I cant continue with Windows 7 so I'd even be prepared to pay an annual fee to keep the support going. Look forward to hearing from you, thanks Julie

I enabled two-step authentication on my Firefox Account by clicking on "Add". Everything went OK. (It was the first time I enabled it. I've been negligent.) The "name" (email) on the token generated by my 2FA App was the primary email of my Firefox Account.

Then I clicked on "Change", and followed through the same steps as when 2FA was "Added". Now, the "name" on the generated token was neither the primary or the secondary email of my Firefox Account ! The name on the token was the email I used as the primary email of my Firefox account back in 2020 ! Despite the wrong name (email), the 2FA code worked fine for signing in. How and why does this happen? What is the intended purpose of the "Change" option?

I fixed the name on the token by Disabling then Adding 2FA again.

A Curiosity?: When I try to sign into Firefox account, 2 emails are offered by Firefox - the current primary email for the account, and the previous primary email for the account. The second email IS in Logins, but not for accounts.firefox.com. The 2nd email is rejected if it is tried to be used. Where is Firefox getting the previous account email from?

I am having trouble with streaming YoutubeTV and PeacockTV on my Firefox browser. I made sure that my browser was updated but I am still experiencing trouble with getting access to online streaming sites.

HI, I am having trouble with not being able to get access to streaming on YouTubeTV and PeacockTV because my current browser on my desktop computer does not support these sites. How Can I update to the latest version of Firefox where it will let me get access to streaming on YouTubetv and PeacockTV?

I'm trying to log into Peacock tv and i'm getting a message that my browser is not supported. It was working for months and I'm suddently getting this error message.

Whenever I try to access Gemini at gemini.google.com, I keep getting a plain white screen with faded, almost hard to see elements that don't do anything even when typing in the input field. (see attachment 1)

I can access Gemini at Google AI Studio (https://aistudio.google.com/) but the UI is also broken on that site, with wide fonts that overlap each other, making text hard to read (see attachment 2).

Firefox version used: 115.28.0esr (64-bit) OS: Windows 7 64-bit

upon clicking on Firefox to open my email via password and email address, I am provided with advertising and the login does not connect to my email. This has been 4 days to 21/09/25

Please can you rectify or advise what needs to be done
