When I try to forward an email, I get the response: Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

The above response was when I tried to forward to another account of mine - both from comcast.net

I have seen some posts on this request but unsure if anything has been done to add/use if already there a feature to make an email account "inactive". I have several email accounts set up in Thunderbird but do not use them much but don't want to delete the account but don't want to have to have them active either. Any update on this issue is appreciated.

As of Sunday, Thunderbird can no longer reach my ATT server to download email. It has behaved for ten to fifteen years. Last time someone at ATT fixed it. I have been on the phone or on screen with ATT most of my waking hours since Sunday. (In the process I lost my internet, my landline, my cell connection, etc.) Everything is restored except the connection between Thunderbird and ATT. Everyone thinks changing my password will do it. Done it four times. It gets me into the ATT mail. I have replaced the password in Thunderbird settings with it to no avail. Is there anything you can think of? Not only is Thunderbird more attractive than ATT, I have thirty years of mail boxes there, a continuation from Eudora. I will appreciate your wisdom.

My calendar is Baïkal 0.8.0 running an a debian 10 server. My thunderbird is 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS My other devices are two thunderbirds 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS and aCalandar 2.8! running an Android 14

It does not matter on which client I add or change calendar entries then synchronize them (I can see on my Baikal dahboard, that the synchronization has succeeded!) the other thunderbird clients don't show the changes, even after explicite synchronization, only after unsubscribing and then new subscribing.

Please advice for help!

Thanks in advance

After installing Firefox on a new Windows 11 laptop, I've noticed some issues with the scroll bar. If I'm trying to view comments on Medium, for example, I am unable to scroll in the comments window as the main page scroll bar blocks it. I did not have this issue with Firefox on my previous Windows 11 laptop. I've tried changing some settings to see if it makes any difference with no success. I found a previous question regarding a similar issue where someone replied with a suggestion to toggle the "Always show scrollbar" option in the General > Browsing settings, however this option does not exist in my settings.

As seen in the attached screenshot, both scroll bars sometimes appear at the same time. However hovering the mouse over them activates the main windows scrollbar, making it impossible to scroll in the comments window. Trying to scroll the comments window with the keyboard arrow keys also does nothing.

I would really appreciate some advice on how I can fix this!

Hi

This has only recently happened but PDF comments are no longer displaying in OWA365 when using Firefox. I can open the same email in Edge and they are displayed fine. Strangely, if I go to print the PDF within Firefox, I can see the comments.

I've set my Application to open PDF with Adobe Acrobat Reader but this makes no difference. Is there anything else I can try?

Hello,

When I open Firefox, it seems like it does not does anything, but then it starts playing a music I was hearing in youtube earlier (like it seems to me that the window is opened somewhere outside of my screen??

If I click a second time in Firefox, then it opens a normal window in my screen as usual, but the other one keeps playing in the back.

I've tried changing screen resolutions, checked that no other monitors were detected, restarted computer,

Not sure what to do next!

Thanks!

I want help to recover bookmarks and password saved on my Firefox browser.

There was a issue with my Windows 11, due to which I was not able to boot on to Windows, hence I don't have the option to export the profile etc. Due to this the only option for me was to copy all the data on C drive through cmd prompt. After having taken all data back, I have reinstalled windows and firefox.

I did some search on the internet to locate the profile files so that I can get back my bookmarks and passwords. However I am unable to locate the same.

Request some guidance and help on this.

thanks Nitin

I'm using Thunderbird 115.10.1 and Windows 11 Pro. Thunderbird has suddenly started sending my partner's emails to Trash. We've been emailing fine for years before this. She has not changed anything in her emailing. I've closed and re-opened Thunderbird. Her emails are not marked as Spam and I have marked some of them as 'not junk'. Anyone got any ideas? I can't seem to find reference to other people having this problem.

Installed 127.0 (20240606181944) from http://download.opensuse.org/repositories/mozilla/openSUSE_Leap_15.5/ and since then I've been unable to:

• Close a window by closing the last tab (the last tab X does nothing)
• The toolbar Account icon has nothing under it, have to go via Settings to manually sync and manage account

I have the same question as the OP in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1265898#answer-1241526].

I am currently finding that the address bar history search using caret "^", does not always list all the webpages that I have visited, especially if I found the page using the search bar within the site. Is there a way to enable Form and Search History in the most recent versions of Firefox as described in the previous post?

Hello and good day.

I am a little lazy and i want to open firefox(one window) on my two monitors, i can do this by open firefox then open another tab, then drag to the other monitor, but i want to know if is possible to add a command on the shortcut and do this in one go.

Note: i am using linux mint 20+.

Thanks.

I'd love to find a solution! Sometimes this happens when opening a link from my email (to a well-known retailer as shown in the images below), and at other times it is in response to a website requesting information as part of a 2-factor ID request or, or even a password change. It has become almost almost debilitating! What setting seems to be wrong here.

I use Webroot SecureAnywhere and the relevant updates are applied automatically.

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

I was trying to download ledger live from an official site when I noticed Firefox had twice tried and failed to download an old version of the tor browser I downloaded a long time ago.

A few hours before this happened my pc froze for a minute.

I'm not sure if I have malware on my device or if this is Firefox acting up. My antivirus scan shows nothing.
