I have an old email with windows live mail and want to migrate it to thunderbird since windows live mail has been discontinued for a while. Every time i try and set it up and migrate it, it doesn't seem to find the email server (most likely due to windows live mail beings ancient) and then I need to manually set it up. But even after trying to follow guides, I still have issues. Firstly, it says the hostname is invalid even though it contains only valid characters. I seriously wouldn't even know where to start. Would it just be easier to make a new email. Any help would be appreciated.

Hi, i cant make some actions in my account in browser game (battleknight) . After click on icon ,,mission,, , page is just refreshed and mision is not activated. Also in Highscore, when i hit some icon to sort players, the same issue always happen. It was OK all years long and game is OK on other browsers, this happened after todays actualization. Thanks for some help. (i tried to restart browser, clear cache)

How can I install Thunderbird on an external USB drive for my Mac, and, import an mbox to it (or a bunch of mboxes?) that also lives on that external drive? And keep this email account data disconnected from the original account it came from, that is, do NOT have it sync with Gmail? Perhaps it's best if I describe my situation and the result I'm trying to achieve.... (sorry for the length of this question; I'm trying to be precise and comprehensive at the same time 😬)

Situation: 1. Used macOS Mail for years, to manage a Gmail account 2. Recently used takeout.google.com to download the mbox for this account, which turned out to be 91.01GB (!) 3. I tried using macOS Mail on another computer to open it, and it's not happening; file seems too large; I get an error message saying the Mac's memory has been used up and Mail has stopped working 4. I'm currently waiting for a subsequent Google Takeout download that I expect will consist of many, many mbox files (each mbox corresponding to its own label, according to How to Download/Export Emails with Google Takeout) 5. I have limited space on my computer and would like to avoid accommodating 91.01+GB of historical email data

Desired result: 1. I'm basically trying to create a back-up of all my Gmail emails so that... 2. I can delete a bunch of them, reorganize them, etc. using my macOS Mail program, while being confident that... 3. I can always return to the easily accessible and searchable emails in Thunderbird

Add'l Thoughts/Specific questions: 1. Can I install and run the macOS version of Thunderbird on an external USB thumbdrive by simply dragging the TB app icon to the external drive to start the installation process? 2. Assuming TB has successfully been installed on the external drive, how do I make sure TB knows that the data from the mbox(es) I import should "live" on the external drive as well?

Thank you so much for reading and in advance for your advice.

bold textspectrum.net email works on one computer and doesn't on my second computer. same setup and password

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

I have been very happy using Thunderbird to access the email account of my volunteer position, I have always used the Email, Calendar and Task feature. I have the automatic updates setup on Thunderbird and until recently had no issues at all, until the last update. When Thunderbird first started with the newest update the calendar details were visible and then Thunderbird disabled the Calendar and Task and no matter how many time I click the Enable button or edit the properties to say enable Thunderbird immeadiately sets it back to Disabled. I have uninstalled Thunderbird, and relinstalled an older version - problem there doesn't seem to be a profile to match, so I just kept manually updating Thunderbird to a newer update until the absolute latest, but there were issues with the profiles again. I then uninstalled and installed the latest version available directly from the website and was able to get another profile to work for my local folders - I had saved some docs locally to conserve disk space on the email server. But no matter what I cannot get the calendar to work at all. There are no posts that cover this particular situation. Any idea how to fix this???? Thank you to anyone that offers assistance with this issue.

Hi.,

On or about Aug. 11, 2025 my email when it comes automatically from Optimum suddenly it's a more computer language email message. For me, it's very difficult to figure it out and it's VERY long. I copied and pasted on line to give you an idea. Here it is: This is a multi-part message in MIME format

just checked my Optimum email box and the messages are in their regular format, so somehow just recently when Thunderbird downloads the messages it gets presented in computer language and the subject and provider are all blank.

Please tell me what I should do.

  Thank you.

I’ve noticed the bloxstrap download page doesn’t load smoothly in firefox, while it works fine in chrome. sometimes the buttons don’t respond unless I refresh. Is this a caching or compatibility thing with firefox?

I have just upgraded my computer from Windows 10 to Windows 11. Due to hardware complications (e.g., new motherboard) I had this done at a shop. I took the computer in about noon on Wednesday, July 30. The upgrade to W-11 finally happened on Monday afternoon, August 11. During that period I received 83 emails to my Gmail account, which of course were not downloaded to Thunderbird, and also sent 13 -- all directly to/from the web Gmail site. Since the activation of W-11 I have received 19 emails and sent 6 -- still all directly from the web Gmail site. Due to additional hardware issues, my computer did not come home until this (Thursday, August 14) afternoon. After I got it hooked up, and running, I brought up Thunderbird. It has downloaded the 83 received + 13 sent, from 7/30 through 8/11, but not done anything with the 19 received + 6 sent emails since then. When I turned Thunderbird off and back on -- or the entire computer off and back on, it has repeated this behavior. Currently I have 332 (83*4) received messages sitting in my inbox, and 52 (13*4) sent messages sitting in my sent box.

What do I need to do, to stop it from repeating this 7/30-8/11 download; and more importantly /start/ downloading messages since then? I feel fairly confident that the timing of the switchover from W-10 to W-11 is not coincidental; and that there is something I need to do in Thunderbird under W-11, to correct this behavior.

All advice will be greatly appreciated.

Thank you, Franklin Coleman

Greetings Ya'll, Firefox Bookmarks are no longer being initially placed in "Other Bookmarks, they are now being placed in the "Bookmarks" that is under the "Open Application Menu" Tab.

I've found that the "New Bookmarks" can be "Dragged" as a copy to "Bookmarks", from the "Bookmarks" located in the menu, for they will stay there unless I delete them

I can not move the "Bookmarks" back to "Other Bookmarks"

Would I lose My Bookmarks, If I "Refresh" Firefox, as suggested in the "Troubleshooting Section? If there is a chance of this happening then that would Absolutely Be Catastrophic!!

In the works of Ai agents that are apparently automating everything (which I absolutely dispise) why is Thunderbird forcing me to send one email at a time so as to not show other recipients who I am also emailing.. I do not have the time for this. I also don't want to invest time into a mail merge set up like Chimp or Octopus. I just want to email 30+ people without the others seeing each other. But when I have tested with thunderbird with one customer email and my own as BCC - when I get the email in my inbox it literaly says - FROM: MY BUSINESS. - TO: MY CUSTOMER.. (yes my customers email address - not mine).. What is going on here?? I can not spend 45 minutes sending the same email... using copy and paste etc..

I am now getting a spinning wheel with annoying frequency while using/trying to use Thunderbird on my MacBook Air 2017 running Monterey. Everything was fine for the first 6-9 months, but over recent months the spinning wheel has appeared more and more frequently while I'm trying to read mail, answer mail, scroll through messages, etc., etc. Now it comes up every few minutes and delays me doing anything for about 15-30 seconds at a time. It's really frustrating. I recently ran Onyx, which was designed to clear cache, etc and make everything run smoothly. But the only program it required me to quit before it started was Thunderbird. Is there some cache or something I need to clear on a (semi-) regular basis to keep it working at a reasonable speed without this godforsaken spinning wheel interrupting everything? Thanks for any/all your help.

Suddenly I can no longer send email. Two days ago, everything was fine. Receiving works fine. I eventually uninstalled and reinstalled Thunderbird, but to no avail. I'd appreciate your help with this. Here are a few images with the settings.

I have not received a reply to my question, and so, I am posting a variation. Suddenly, messages I receive lack chronological order of reception, though I have indicated that I want received order. Old messages and new messages are mixed. What do I need to do so that all received messages are in chronological order, as they always have been?

I'm trying to copy an older Thunderbird profile so i can add it to my Thunderbird installation on a new computer (where I already have a profile and a bunch of mail). When I copy it, near the end of the copy process I get this strange message: "Replace the file 'Inbox.msf"? An older file with the same name already exists in 'mail.cyberacc.net'.

Original file: 143.3 kB. Last modified 2014-08-22 12:57:00 Replace with 122.2 kB. Last modified 2014-08-23 23:08:25

Curiously, no accounts from mail.cyberacc.net show up in my accounts sidebar. Under 'Account Management' it shows as 'XMPP - nn@cyberacc.net'

How can two files with the same name but different dates exist in the profile? What should I do in response to this prompt? Cancel? Skip? Replace?

Thanks
