Hi, am getting this error and am unable to use our new PC as this Thunderbird mail app is failing to migrate the profile from the other windows PC. Need your help asap on how to fix this. Not very technical, so need help. I updated Thunderbird to the latest version (115.11.0 32 bit) on my old PC before copying the profile over and loading Thunderbird on this new PC which has 115.11.0 64 bit version.

Uncaught (in promise) NS_ERROR_FILE_NOT_FOUND: Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIFile.copyTo]

Hi, I have had Thunderbird on my Windows 10 laptop successfully for many years. Today I added a new email account, but then Thunderbird kept losing connection. I thought I'd try uninstalling and re-installing it, but now I get the message that it can't be installed on my laptop. Anyone know how I can get round this?

I can't get on with Thunderbird 115 so want to install an earlier version. I have installed 102, but it asks for my school or work account log in, which I don't have. How do I achieve what I want, and stop thunderbird updating to 115. I need a quick answer as I have just made a donation to you, and if I can't have what I want I will ask for my donation back.

Watson.

I just purchased a Google Pixel 8a, and needed to install the reader for my Yahoo Mail account. When I searched for Thunderbird for Android, I found Edison Mail+. How does that fit, or is this something I don't want?

Is there - yet - a Thunderbird for Android? If not what do you recommend? I had been using K-9 mail on my Pixel 6a (which, I had understood, was the forerunner of Thunderbird for Android), but it just doesn't want to install on the 8a.

With the latest update 115.11.0 the existing profile was not identified and loaded. All existing configurations, mail and address book are not accessible. The likely problem is the installer program that uses IP address as a factor in finding the correct Thunderbird account. I use VPN and do not have a static IP address. I have been shut down for several days now and any attempt on my part to resolve the issue has failed. The old email is very significant. Unannounced updates can cause serious trauma for Thunderbird users.

I'm moving from win 10 to 11 in new PC. I downloaded Thunderbird. I have hidden files showing in new PC so I found where it should be. When I look for the Thunderbird I downloaded it's not there in roaming...so I can't move my profile into the new computer. I have it on a drive read to install, but it's not showing up.

i have 2 computers running the latest thunderbird 115.10.1 (64-bit) one is in perfect layout exactly the way i want it the other has more layout issues than i have time to fix to make it back the way i want ( a fresh install ) i just want to copy the lay out not the accounts , not anything else is there a file or 2 i can just copy and put on the new computer ? and make thunderbird look normal

I am replacing a ten yr. old Dell Desktop with a new HP Laptop. Can you please let me know how to get the new laptop working with my existing Firefox (v125.0.3) with current add-ons, extensions and settings? Thank you for your time !! Rick Perry

I access a Gmail account with Thunderbird from browsers on differing machines. I also tried using Thunderbird itself to access the mail in Gmail.

So we have three different pieces here: A) Gmail account itself B) Thunderbird's view of the gmail account C) Thunderbird's local folders

What I was expecting was:

1) Thunderbird would pull copies of info on gmail (A) to Thunderbird's view of gmail account (B).

2) I would drag and drop folders or emails into the local folders (C) from Thunderbird's view of gmail account (B)

3) I would end up with gmail itself (A) having the email, Thunderbirds view of gmail account (B), and a copy in local folders (C).

You'll ask "Was it IMAP or SMTP/POP?". I entered the info in TB for the IMAP. There is SMTP information too that I see in TB. However, on gmail's settings on gmail itself says IMAP is disabled. POP is not disabled.

What I've got is confusion and things not where I expected.

1) I had Thunderbird pull info to its version of the gmail. 2) I dragged and dropped things (folders and emails) into local folders thinking I was making copies

Instead of what I expected, I ended up with:

Gmail account (A): All the tags somehow got pulled and the email is all sitting (I think maybe) in 'All Mail'. Not sure as there are hundreds of emails to look at an I think some things have been taken out of gmail.

Thunderbird's version of gmail account (B): Had a lot of email from gmail that had identical folders under the account in TB. Now those folders under TB's version of the email from gmail are empty.

Thunderbird's local folders (C): I think all the missing email from both gmail (A) and Thunderbird's version of the gmail account B) are now in local folders.

That's very much not the outcome I was looking for. I also was unclear was whether folders under the gmail account in Thunderbird were (in fact) local... the presence of the 'local folders' separately left me unsure.

I haven't used a mail client for personal use for a decade or more now. I use webmail (gmail). However, I wanted to do what I would have done in the old days - I wanted to pull down a copy of everything in gmail and save it (back when, it would have been as a .PST).

Mostly I was hoping for: I) Gmail mail is left on gmail. II) TB's version of the gmail account holds a copy of everything in gmail III) and I can backup, with a structure similar to gmail being preserved, a local repository (in whatever the right export format is these days) IV) If I'm in Thunderbird, I can send an email via gmail

I believe I can get every email that was messed up on gmail back there with some work. What I don't know is how to do what I want to do , as described immediately above. (Items I, II, III, and IV)

How can I do those things?

And are the folders under the gmail account representation in Thunderbird actually local? If so, why is there also local folders?

My computer updated with no warning one night, and i lost all personalization and even everything stored in my firefox, the sign ins, passwords, bookmarks, all. is there a way for me to find all that was erased?

Hello, First post and could not find this surprisingly... I'm wondering what settings to use for windows 11 VPN section. i installed on my desktop but when i go to VPN settings in current win 11 it does not list a VPN. is this possible to use Mozilla VPN at OS level or is it only via ff browser?

 Thanks! 

I love Mozilla and what they do with their products! :-)
