Hello.

I've found myself to rely on Firefox for some specific workflows that require sending emails that are generated automatically by a website, and I use it across multiple devices, such as Windows, macOS.

Unfortunately, when it comes to iOS, using the aforementioned website, when tapping the relevant "mailto" button, nothing happens.

Some months ago the specific website that I use, was failing to do this action on any webkit browser, but this was later patched by the developer and the flow now works correctly within Safari. This was caused by stricter enforcement of "user-initiated" actions.

Unfortunately it seems that Firefox isn't either capable of invoking the mail client, or get the data from the website properly.

Some mail can not be delivered to sender. I am having mail is turned back and explanation about : I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below. For further assistance, please send mail to postmaster. If you do so, please include this problem report. You can delete your own text from the attached returned message.

                  The mail system

But sometimes it goes very easy the same mail? How does it come? Same mail will pass and same mail will not pass sometimes?? thank you Nikola Guslov

Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

Without client certificate configuration, the user can retrieve its emails on the dovecot IMAPs server using a password.

When I try to authenticate the user with an S/MIME client certificate, the dovecot server reports that: ```dovecot: imap-login: Login aborted: Connection closed (client didn't send a cert) (client_ssl_cert_missing)```

Here is the configuration: 1. On the client side: I've imported into thunderbird: - the self-signed CA certificate - the user's S/MIME client certificate which is fine: ```

1. pk12util -l user@example.com.p12

Enter password for PKCS12 file: Certificate(has private key):

``` I've setup the account to - use its certificate - use a TLS certificate as an authentication method. There is no S/MIME certificate option.

2. On the dovecot (2.4.1) server side: The server is configured to require client certificates for all IMAP connection: ``` protocol imap {

 ssl_server_ca_file = /etc/ssl/CA_CRL.pem
 ssl_server_request_client_cert = yes
 ssl_server_cert_username_field = commonName
 
 auth_ssl_require_client_cert=yes
 auth_ssl_username_from_cert = yes

} ```

Does that mean that I also have to import a TLS client certificate? If so, what format should it (.p12, .crt...) be?

Hi Guys,

I have an issue. I noticed now that if i click on one of my 300 tabs of website tabs, it automatically goes to some domain reseller and removes the whole link / information on the link that shows which tag or data i had on that link in the tab. If that makes any sense?

I hadnt yet gone through renaming all the tabs when the website changed domainbs and now i am unable to as the minute the tab wakes up from beind discarded, instead of coming up as can not find website (at which point in the past i could just change the 2 characters to the right domain), it goes to the domain reseller and removes the whole link / data that it used to point to.

Anyone know of a way i can do change the links on a mass scale of all the tabs i have?

Ich hatte immer Thunderbird, habe das Programm neu installiert und jetzt muss ich ein Paßwort eingeben. Bisher mußte ich das nie tun. Also habe ich keins das ich eingeben kann. Das ich keins eingeben kann, ist ein Herstellen des E-Programms nicht möglich. Was kann ich tun. Ich benötige das unbedingt wegen der eingehenden Mail. Viele Dank für Ihre Hilfe

I've been using Firefox for a long time, but recently, browsing YouTube has become a nightmare. The newsfeed lags significantly and scrolling is not smooth at all. Interestingly, the same site works perfectly fine on Brave and Chrome. I've tried clearing the cache, but the stuttering persists. Please optimize the hardware acceleration and AV1 decoding for mobile devices. Hoping for a fix in the next update! Also sometimes YouTube videos don't play. But the same video plays in another browser on the same internet.

Today (February 25, 2026) I received an email notice, apparently from Mozilla Monitor, advising me that my "Email addresses, Partial credit card data, Passwords, and Phone numbers" had been exposed in a data breach at Canadian Tire. This email seemed legitimate (the sender was breach-alerts@mozilla.com), but since it gave me a link to login to Mozilla Monitor, my first concern was that this might be a phishing email and it would be dangerous to click on that link. Instead, I went through the Firefox settings to login to my Firefox account and from there, I checked what Monitor had reported. The Canadian Tire breach was not listed there. However, when I went to haveibeenpwned.com, the Canadian Tire breach was listed there. It showed that the breach occurred on October 25, 2025. So why was the breach not listed for me on Mozilla Monitor? And why would I have received an alert from Monitor 4 months after the breach? Was this breach alert notice actually a phishing scam perpetrated by someone using the information from haveibeenpwned.com as bait?

I recently created a theme. I got the answer to my question in it. But I can't answer myself! When submitting the form, a message appears: "This page is not working. Contact the website owner." Where should I write to? Tell me please. I need to reply in the topic.

Hello. It could be cool to be able to personalize the tool on Android, just like the desktop version. Is that in that pipe? Is there a proper way to make suggestion? Sincerely, Maxence.

I went to [https://support.mozilla.org/en-US/kb/firefox-backup] and under "Create a Firefox backup file" at step 3 it says, "Scroll down to Backup, and click Manage backup" but when I went there no such "Manage backup" option exists as you can see in the attached screen capture. So what gives? How can I "Create a Firefox backup file"? I am using Firefox v147.0 (64-bit) on Windows 11 Please instruct. Thanks RJB

Youtube's mobile site isn't loading since the new Firefox update. It gets to the attached screen then doesn't go any farther and I can't click on anything. I tried disabling my extensions and this didn't fix the problem. The desktop site loads but is not very mobile friendly.

Hello Mozilla Support Team, I am writing because my primary email address associated with my Mozilla/Firefox account has been compromised and I no longer have any access to it. Unfortunately, this prevents me from performing basic account management tasks. Specifically: • I would like to add and verify a new email address (*censored@outlook.com) as a secondary email so I can later promote it to primary. • However, when trying to add any secondary email, Mozilla sends a verification code/link to the current primary email address — which I cannot receive anymore. • As a result, I am completely locked out of updating or securing my account, even though I can still log in with my password (and possibly 2FA if set up). My new desired primary email is: *censored@outlook.com I have read the official documentation (e.g., https://support.mozilla.org/en-US/kb/change-primary-email-address-firefox-accounts and https://support.mozilla.org/en-US/kb/ive-lost-my-firefox-sync-account-information), which states that changing the primary email without prior secondary email setup is not possible for security reasons when the old primary is inaccessible. Questions: 1. Is there any exception, manual verification process, or alternative recovery method available in cases of compromised/lost primary email access? (For example, through identity verification, account recovery key if I have one, or support-assisted change?) 2. If no recovery is possible, can you please confirm that creating a brand-new Mozilla account with *censored@outlook.com is the only remaining option, and advise on how to best migrate my synced data (bookmarks, passwords, history, etc.) if still accessible on my devices? I understand the security implications and that Mozilla prioritizes protection against unauthorized changes — I just want to regain full control and secure my data properly. Thank you very much for your help and any guidance you can provide. Best regards, Francesco Intini

Open tabs page keeps jumping to older open tabs and not the most recent. The screenshot I attached shows the open tabs page, there are more above this screenshot. This screenshot is the bottom, showing the most recent open tabs. Two versions ago, whenever I opened Firefox it opened two the most recently opened tabs… now with the latest iOS version it opens with an arbitrary old tab forcing me to scroll down to the bottom. Even if I just minimize the window to view another app, when I return to Firefox it jumps back to an old open tab again forcing me to scroll back down to the most recent. Needless to say, this is extremely annoying and I’m reporting it to you in hopes that you will come out with another update and fix the problem as soon as possible. Thank you very much..
