I have a new w11 laptop. I would like to install Thunderbird. I have 8 email accounts on the old W10 computer. I plan on keeping the old W10 computer running and using TB. All my accounts are IMAP--Yahoo, gmail, hotmail (now outlook) but I have an pretty extensive Local folder collection on the old W10 Would I be better off just installing TB on the new W11 computer and adding each email and start fresh or should I venture into copying the W10 profile (some of the instructions seem a bit confusing). If I add all my emails as a fresh start to the new W11 computer could I then just copy the LOCAL folders in the W10 Profile and paste it into the W11 profile?

In Windows 11, the Address Book is accessed via an icon on top left of the TB main page or Alt+2. In Windows 11 is there a similar key combination to view the folders below Local Folders?

Thunderbird freezes/hangs on restart (mac OS 15.4), including in safe mode. I've updated to 137.0.2 from 129 and the same problem occurs. It only displays "Looking up gmail.com" and I get the spinning disk of doom and have to do a force quit…

I've used Thunderbird for years, and I LOVE it! A few days ago, my hard drive died. I had it replaced, and I've used my data backup to recover much. I did NOT have programs/apps backed up. I need VERY SPECIFIC steps to download and reinstall Thunderbird so that it uses my old profile. Should I first delete EVERYTHING having to do with Thunderbird and start anew? I did download it today and then went to the C:Users/Owner/AppData/Roaming/Thunderbird folder. In that folder, I deleted the "new" profile file (I think!). Then I moved my backed up folder called Profiles into that directory. I tried to get Thunderbird to use that profile, but no luck. I'm reasonably intelligent (I've been told!), but I can't figure how to do this, and I truly need a step-by-step blueprint. Do I download Thunderbird first? If so, what do I then do to make it find the old profile. I'm running Windows 11 Home on a PC. Right now, I'm going for a long walk to clear my brain. In the interim, if one of you really smart, nice experts could give me instructions on how to do this, I'd be eternally grateful. I have numerous folders, and some really important old emails in that old profile. I also would like to be able to retrieve my address book and calendars ... which I ASSUME are part of the old profile. Thanks in advance for ANY assistance! Don't assume I know ANYTHING!!

A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

I upgraded my PC, having backed up everything on Carbonite. On installing Thunderbird I cannot get it to recgnise and use my original Thunderbird profile downloaded from Carbonite. Peter Millar

My attempts to install Thunderbird on my new Lenovo computer always fail and end with a notice saying that the failure is due to the application being 'malformed'. I use Google as my search engine.

My old computer (also Lenovo) happily ran Thunderbird on Google.

Please help Thunderbird is by far the best email service I have used.

Hi - I have been looking for over 2 days. How do I import all my data (emails, addresses calendar) from Outlook to Thunderbird.

I have tried Import tool within Thunderbird - import from Outlook. I tried MailStore and was totally confused - the terminology was strange. I managed to make an archive - it took ages to find where it was and I still do not know the file extension.

No videos...nothing.

Thanks

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

Heads up for custom installs: running tbird and firefox on linux, I install both in my home directory for my own ease of updates and portability. I get releases from https://ftp.mozilla.org/pub/ in tarball formats which install in 30 seconds. I recently ran into a problem which I've not seen before. recent d/l of firefox-136.0.tar.xz for linux-x86_64. It crashed immediately with err 126. The ff.exe and ff.bin files were for ARM arch. This wasn't easy to locate and I think it was caught but anyone still headscratching may want to see if this is an issue - I had a good 136 on a laptop and overwrote bad install on desktop.

I *think* I've followed the instructions, but I am unsuccessful in moving Thunderbird Profile to new PC. I copied old profile to external drive. I opened Thunderbird on new PC and found Profile folder. I went up 3 levels and pasted old profile from external drive into folder on new PC. But my old data have not moved. When I go into new Thunderbird and choose "open profile folder", it shows me 3 files: the two that the system created in the new download, plus the old Profile that I pasted there. The new version of Thunderbird uses the "new download" profile as the default. What am I doing wrong? Thanx!

I recently moved my TB to a new PC desktop, and TB is working fine. But I see that my local archive folder is gone from both the new and the old PC, as well as my NSTMP folder. Could someone help me locate them?

thanks

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

Κατέβασα το Firefox Installer.exe και προσπαθώ να κάνω εγκατάσταση με το Run as Administrator διότι για κάποιον λόγο δεν με αφήνει διαφορετικά, αν και έχω δικαιώματα διαχειριστή. Μου βγάζει όμως ένα παράθυρο το 7-Zip και μου λέει "Δεν επιτρέπεται η πρόσβαση".

I have used Firefox for longer than I care to remember and have never had any problem with it but this morning I switched on my PC and a new AI side bar has appeard on the left and I don't want it. Can you please make it so we can remove it and looking around the internet, I know I'm not the only one with this opinion.

The site (which I have used before on this phone) now tells me I must have Javascript enabled. I have looked through SUPPORT and I see 44 other inquiries on this topic but no answers. HELP!

Please indulge this silly question. What possible benefit is there for Mozilla continuing to list this page with the very first, oldest Firefox release at the the top, requiring the user, every time they visit, to scroll to the middle of the page to search out the current latest version instead of having the chronological order from latest to oldest instead?

Hi. On an Active Directory, we deploy Firefox (normal or ESR). It's OK. When we deactivate the link of the GPO, it's supposed to uninstall. But it doesn't (even if we delete the GPO, specifying to uninstall at once).

The gpresult command on each computer doesn't show the GPO anymore, but Firefox is still installed.

( FYI, we used to do that with FrontMotion Community Edition, and it was always working (instal and uninstal). We even just tried the "last" (but old) ESR edition present on the FrontMotion site (CEESR-102), and it works. But FM CE version has stopped being developped. )

So, any idea about why the official Mozilla Firefox version (normal or ESR) doesn't uninstall?

Thanks by advance.

I recently donated to TBird but it is unable to send any emails. So I uninstalled it and tried to download a fresh copy but I couldn't avoid the donating page. I paid again but I just get a page telling me to finish downloading - but not how to do so. I've waited half an hour but nothing has been downloaded. If it's still possible to download TBird, how can I do it - preferably without repeatedly paying?
