I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

Hi everyone,

I run an online barber supply store called Magnus Supply (https://magnussupply.com/) where we offer a variety of products including clippers, trimmers, shavers, grooming products, accessories, and sanitation supplies. I'm always looking for ways to improve the user experience on our website and streamline our e-commerce operations.

Can anyone recommend browser extensions that could help with:

Enhancing website performance and speed. Improving user engagement and retention. Simplifying the checkout process. Better tracking and analyzing customer behavior. Ensuring data security and privacy for our customers. I’m particularly interested in extensions that work well with Firefox, but suggestions for other browsers are also welcome. Your insights and experiences would be greatly appreciated!

Thank you in advance!

I am trying to transfer my email from one old PC using windows Live Mail (2012) to a laptop with Thunderbird to process the emails. The email server is with a company called Plusnet, and they can send me their own emails, which are received by Thunderbird on my Laptop. All my other emails continue to be sent to the Windows Live Mail on the old PC. Plusnet advise me that the problem is with Windows Live Mail. Any ideas how to resolve the problem? David Owen

After Thunderbird asked me to download a new version & I donated money, all my subfolders to the left have disappeared. ALL my information stored/ emails placed in the subfolders are gone. I have sent several requests asking for HELP. This has been so frustrating I do not want to recommend anyone to use Thunderbird. This has nev er happened to me before and I cannot seem to receive an easy solution a t my end. All folders & emails dumbed into folders are gone???? I need HELP Please.....

I have have been unemployed at the time but still donated $$ to support as often as I can and this has happened which has been a nightmare.

I have downloaded my Emil to my laptop using thunderbird and then I try to change the name of storage folder to D:\gmail and after that I could not find my previously downloaded email.I need to jknow how I can file my previous downloaded folder.

I have been stuggling to transfer my emails from a windows PC using Windows live Mail, to a laptop using Thunderbird. I have just spoken to my email provider (Plusnet) and they have sent a test email which is received by Thunderbird. But all my emails keep arriving on the old machine. Any suggestions which might help me? David Owen

Install of Thunderbird accepted my donation but does not complete the install. It just returned to the donate screen again. If I try to return to the install exe it wont pass the donation screen. I like Thunderbird but not enough to pay twice. How do I get the install to complete? Appreciate any ideas. Thanks

I recently lived thru the Cox-Yahoo conversion. Yahoo webmail has a folder called SPAM..where all the what I call JUNK goes to but in TB but it never gets into the TB JUNK folder..I can only see it on webmail Yahoo..How do I point the TB JUNK to link with this SPAM Yahoo folder please?

I installed the Thunderbird software on (2) devices to replace the Windows Mail product. On the first device (Windows 11 laptop) I was able to add all (3) personal email accounts needed (1 Spectrum and 2 Gmail). On the second computer (Windows 11 MS Surface) i was only able to install (1) Gmail account and the Spectrum account. The second Gmail account gives an error when it tries to verify the account with Google giving the error as follows.

400 that is an error. The server cannot process the request because it's malformed. It should not be retried. That's all we know.

Since the settings on both computers are the same for the account and both Gmail accounts work on one computer this doesn't make sense to me. Any suggestions would be helpful.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

Is it possible to install TB (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles.

Windows 11 is consuming nearly all of the C: drive. I badly need to get TB (and Firerfox) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

I've read everything I could find here and all of that is about using an external drive as a backup. Most of the other help I've found on the web is clearly outdated.

Thanks. jt
