For some reason, my Thunderbird recently "updated" to version 115.10.2, and the "About Thunderbird" dialog says that it is on the "esr update channel." I can find no information about the esr channel. However, when I start Thunderbird, it displays the "Welcome to Thunderbird DAILY" screen. Am I correct that this is an error? If I were really on the daily channel, I think that the version number should be higher.

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

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?

Need to set up Thunderbird to receive emails from yahoo. Cox is transitioning emails to yahoo presently have two addresses : cliven@cox.net and daciaandclive@cox.net

Hi, I have upgraded my computer and Thunderbird, however only the INBOX folder is loading.

I have followed the instructions to migrate the folders from the 'Profile Folder' on the old computer, the data has transferred but is not organised as folders, as on the old computer and of course on the main server.

I don't mind if all the data is not on my computer so long as the Folders are there, empty or not but organised in as they are on the main server.

I'm wondering if I selected an incorrect setting while setting up the account within Thunderbird on the new computer.

Thank you and kind regards, Mark.

Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

• https://support.mozilla.org/en-US/questions/1257997
• https://support.mozilla.org/bm/questions/1258023

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.

When I looked at my profile I find that there are several folders created for each of my email addresses at different times. I had wondered about the possibility of clean install of each of the accounts (IMAP) so this would pickup everything from the individual servers. Then copying across the local folders and my address book. Is this possible/feasible? Would it just be easier to import everything? Where is the address book stored. I also have TB backed up on an external drive (insurance). Thanks

System is win 11, latest TB, personal gmail account of long standing. I want to use TB as my email program for gmail. After installing TB, it asks for my gmail login and password, and recognizes the account, defaulting to IMAP, Oauth2, etc. When I press "done", I get a google screen saying that TB want authorization to access gmail files. But when I press "allow", the TB page shows an error message under the password field reading "Unable to log in at server. Probably wrong configuration, username, or password." I understand it is looking for my gmail username and password, and these are correct. I have tried this many times, including with variations: removing and reinstalling TB, creating a pw just for TB in gmail (subsequently deleted). I have read all of the gmail installation help notes at Mozilla. Most relate to a 2022 change in gmail re Oauth2. Nothing helps. Any advice?

When I try to set up Thunderbird on a new computer, it won't connect. And Thunderbird changes the port settings that the provider uses to something else. So I can't use thunderbird with my email address: sheilah@got.net

Since support is being discontinued for W7 Firefox, would someone please recommend the best version of Firefox for Windows 7? Security is not a concern, since I have reliable 3rd-Party security setup(s) for my Windows 7 systems.

Thanks!

I am getting an error that "you have launched an older version of Thunderbird" Every time I try to open my email. I was using the latest beta version up to three days ago and the program got corrupted for some reason. I did try to install the latest beat online beat 2 .

Thanks, Al

I am about to lose access to my work gmail account (new job). I used Google Takeout to download all my emails in .mbox format. I then used Mozilla Thunderbird (with the ImportExportTools NG add-on) to access the emails. They are currently available in a folder called WorkEmailBackup within my local folders section on Thunderbird.

I would like to add these emails to my pre-existing personal hotmail account. I have set this account up on Thunderbird. However, when I drag the WorkEmailBackup folder into my hotmail inbox (in Thunderbird), not all the emails are copied over. Thunderbird says there are 7730 emails in the WorkEmailBackup folder, but only 2212 will copy into my hotmail account. I have tried several times, but the transfer always stops at 2212 emails, and I can see that emails are missing. I have also tried highlighting the emails individually (rather than copying the whole folder), but have had the same problem.

Please help :(

Malware has taken my backup email address and is using it to take over. [Email address] and [email address] are to of my accounts being used to steel everything. Messages, phone calls , device, etc are being stored in hidden files in Drive , application selection options are unavailable etc

I have been using Firefox for ages and never had a problem - love it - but now I see the remark: Firefox has ended support for Windows 8 and Vista on my screen at the right top corner. It also will no longer update my computer.

I do have and use Windows 10 - so I don't see what is the problem? I tried to refresh and that didn't work either.

Please help because I like to stay with Firefox but I do need to update and keep my computer secure.

I am not very computer savy so please tell me what to do in simple word.

Thank you for your help Christine
