I really like this app. I always use it on desktop also but after a few last updates I noticed that battery usage of this app increased a lot and the percentage is very high. 1 hour screen time on youtube was 4% battery usage but on the firefox side it was 17 min / 11% battery usage. If you fix this It will be perfect for me. Here are the screenshots with different days. And I'm using sync feature and ublock addon. I always close the opened apps and I use deep sleep feature on my samsung device. And I forced to close the app. For now I stop using firefox for test purposes.

Hello. I was searching my Inbox for e-mails I knew I had, but they weren't showing up! After doing a general search, I found the e-mails in the search results. Then, I clicked "open in conversation" and they were all there and labeled with "Inbox" or "Sent" folder, respectively. So I right-clicked and selected, "open in containing folder", but it didn't work! The "containing folder" opened [i.e., the Inbox], but didn't show the e-mail! So then I searched manually by scrolling in the Inbox to the date of the "hidden" e-mail -- yet it wasn't there!

(In other words, when I did "open in conversation" from the search results, it showed the conversation, but I can't actually see the e-mails in their containing folder!) Besides for this problem, but I think there are a lot of other e-mails that are "hiding" in this way as well. What should I do?

Thanks for any help you can provide!

Sincerely, Jonathan Rosenberg

Hello. I need help getting Thunderbird to stop marking and sorting certain emails as threads. Seems to be completely spontaneous and for no apparent reason, even in the inbox. I have never actively marked emails as threads. I've tried to remove the "threads" function in the folder settings, but it doesn't seem to have helped in some cases. I also need help with getting the email "unstuck" from the thread structure, I have tried "Ignore threads" and "Ignore subthreads" with the result that the email disappeared. The documents I have seen have not been of any help. Reply preferably to my usual e-mail address, have a bit of ours with mail in the G-mail account.

  Please Bosse

Some hours ago my iCloud account stopped working on Thunderbird; I already tried re-entering the password, deleting and trying to add the account again, but it isn't letting me add it again, my account is working fine on all Apple devices and I have access to the mail on browser.

I've tried using the main iCloud address, the "alias" address, and using the real password as well as the unique "App Password".

Thunderbird version is: 115.7.0 (64-bit)

Dashlane extension is not loading passwords into Firefox. I have refreshed Firefox and I have reinstalled the Dashlane Password Manager extension for Firefox. It used to work so well. I am using Windows 11.

Am getting the 403 error message when trying to log on to a news site which was previously accessible. I can access the site from another browser but not via Firefox. What could be the problem and how do I fix it? Thanks

Microsoft Outlook sign in screen does not load on Firefox. Please see the attached image. Every time I need to read my mail I have to open Chrome , which definitely I want to get rid for good. Any solution ?

How do I disable the mozilla.com news popups? I keep getting annoying news popups with Mozilla.com written at the top of the popup. Todays was USAToday. I did not request this and I want it gone.

Every time I am trying to search, google is always pinned on my search bar, and I want to get rid of it. How can I remove google? (On the image I marked the issue with a red circle)

When I attempt to send an email, I get this pop-up:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: impout006.msg.chrl.nc.charter.net cmsmtp 15.181.97.27 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

My ISP is Spectrum, they said issue is with Thunderbird, incoming s/b 993, outgoing 587, which I confirmed. How can this be fixed?

I have Thunderbird, version, 115.6 on my iMac. Up until this morning I have had no problems.

First when I used "Get Messages" this morning it kept telling me there was an error with my server. But after the error was fixed by contacting the server, Thunderbird was no longer able to connect to the server any more. I can send messages ok and they go through but I can't receive them since "Get Messages" no longer works.

My Apple Mail program on my laptop works fine, so the server is back to working properly and I can pick my Thunderbird sent messages there.

How can I get Thunderbird to connect to my server again for incoming messages?

Thank you, Martha

Hello, Experts:

First up, I'm a happy user of Thunderbird with some years of experience. I make use of filters, and up until about 2 weeks ago they all worked. Now two of my filters (not all) have stopped working automatically, and I have to go to Tools/Message Filters and run them manually.

I'm on TB 102.15.1.

I have deleted the non-working filters and re-created them. No change in behavior.

I would NOT like to de-install/re-install TB because it's a good deal of work, and TB is a critical system for me.

That said, I keep a laptop computer for travel, and the filters work on that platform. IS THERE A WAY to copy a file or folder over from the working laptop onto my desktop machine, where the filters have failed?

Thanks in advance, Bob

I'm very confused. I've been using Thunderbird as my email server for a few years. Recently, I stopped receiving emails December 12, 2023. I sent in a problem according to the help page that I found. I believe Mozilla is now the server for Thunderbird? I don't even know if that is accurate (part of my confusion). I followed prompts and confirmed my email address, apparently I now have a user name. I still can't send or receive emails. Can you help. I need step-by-step instructions, please.
