Hi, Id like to newly install TB - but have all my old emails stored in folders which I cant get hold of right now (I copied them directly from the application folders/user data, not using any program for it) So if I install TB now - will it be possible for me to LATER add the old files/folder structure etc - and without overriding anything?? Thx very much in advance!!

All,

I am being prompted to update thunderbird from 45.8esr. There is no 45.9esr available? Several weeks ago when the notice was triggered by a bug in the esr update path I was upgraded to 52 which broke lightning and would not recognize the GTK+2 theme. 52 looked horrible and there was no way to make it usable with a dark KDE desktop. Has this been fixed so I can feel confident about the update. There is no technical reason not to continue to support current themes as they work fine with 45.8. There is no reason not to continue to support the current GTK+2 themes until GTK+3 stabilizes and there are adequate themes available to work with dark desktop themes. Let me know, I'll stay at 45.8 until this is fixed.

(I apologize if you get 2 similar copies, the mozilla support site choked because I hadn't clicked on the confirm e-mail yet)

Mac OS 10.11.6, MacBook Pro. I just installed Thunderbird as my default mail app, changing from the Apple Mail application. I have a few issues: 1. I can't set up an incoming mail sound. It is grayed out in Preferences/General. I followed the Help article but it does not apply/work. 2. Messages in my Inbox disappear after I read them. They are going to the Trash folder or the Archive folder. Some are gone all together. I want to keep them all in the Inbox until I decide to move them. How do I do that? 3. In my Apple Mail app I have a few dozen sub folders (mail boxes). Thunderbird did not import them and their messages. I followed the Thunderbird Help article about it, but it did not work. 4. When composing an email message it is double spacing netween paragraphs. I would like to single space instead. Is there a way to set that up? Thanks. Christian.

I transferred, successfully, my emails from an old computer to a new one. However, I has used the new one, briefly, and had some important emails that I did not want to lose. I thought that I would be given a choice to merge old with new but the result was that when I go into ...AppData/Roaming/Thunderbird/Profiles... I see TWO files: one that is identical to the one in the iold computer and another which I assume contains the emails I had in the new computer and have now disappeared.

How do I access that other file: xxxxxxxx.default  ?

I recently got a new computer and could not download Firefox. I have tried several different ways and keep getting the same results. On Microsoft Edge when I’d click download it would say the page can’t be reached. So, I tried Chrome, and it says that it isn’t connected to Internet. It is only when trying to download Firefox when I encounter this issue.

All services for Google and google play and Microsoft and windows and all software and data and all and apple I so iPhone iPad service and rigestri follow on system.

None of the available migration or restore methods are capable of preserving OneTab data. In every case I have tried, OneTab is missing from the add-ons in my new installation or profile. The only approach which achieved anything at all was to replace the entire .mozilla director under Ubuntu, but even this only displayed the OneTab page and its data on the first invocation of Firefox. Since the add-on was not present, the data was gone at the second invocation. However, repeating this process at least allowed me to export the OneTab data from *one* profile on the first invocation. Unfortunately, this method is completely useless under Windows, as are the recommended approaches of using Firefox sync (with sync turned on for add-ons) or replacing the contents of a newly created profile with the contents of an old or saved one. How can I properly backup and restore or migrate a Firefox installation, *including* my OneTab installation and data?

I have read probably 100 of your help topics and none of them seem to address my topic in plain english. I have used Thunderbird for years on a windows computer (currently windows 10, Tbird Ver 78.6.0) and I am trying to move my profile from my windows computer to a new Mac running Big Sur Ver 11.1. Thunderbird (for some unknown reason) actually created 4 different profiles on my windows machine (two under: users/alan/AppData/Local, and the same two profiles under users/alan/AppData/roaming) but I have figured out which profile that Thunderbird is using based upon the help/troubleshooting/profile folder/open folder (which happens to be one of the ones located under: users/alan/AppData/roaming) and it is 13.9GB. I copied this folder (and all included files) to a jump drive so that I could move it to my new Mac.

  I am new to Apple and know nothing about their operating system.  I downloaded Thunderbird from the Mozilla website and installed it according to their directions.  I finally found the default profile on my Mac that was created when I installed Thunderbird and I deleted it.  I copied my existing windows profile to the same location.  Now when I start Thunderbird I am greeted with a message that states: "Your Thunderbird profile cannot be loaded.  It may be missing or inaccessible."
  Obviously I have done something wrong.  Please direct me how to correct my problem -- it seems like this should be pretty simple, but I am lost.
  Thank you very much!!
