Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version.

He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur.

He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago.

So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different?

Thanks very much for the help. Tony

I just upgraded to 128.2.2esr and cannot receive or send messages after the update. I have restarted the computer and tried again - still nothing. I'm unable to use a tool that is critical for my daily needs.

Trying to send just says "Connected" or "Sending" but never completes. Worked fine before the update which was just in the past hour or so.

Same issues with downloading new email or sending email for all accounts. :(

Anyone else having problems? Ideas?

Thank you!

About a month ago I began the process of upgrading from W10 to W11. In the process, several problems happened. One of the problems was with Firefox. After reading and trying many suggestions from the Mozilla site, as well as several other sites, and having no success, I posted my problem on this Mozilla support site and hope that there was someone who could help. There was. After several days of exchanging messages (suggestions, instructions and results - mostly about Profile), Firefox returned.

The other major problem is Thunderbird. I have downloaded a current version (128.5.2esr). I have run it twice and, each time, email was downloaded. So that part seems to be working. What doesn’t appear are the settings I have used and message folders I have created over several years. I suspect that the problems are Profile related.

Starting from Help in the Thunderbird menu, then Troubleshooting Information, then Application Basics, I see Profile Folder. On that line is a button labeled Open Folder followed by (Local Drive). I click Open Folder and File Explorer opens to a folder named ab3xaztm.default-esr. It shows that the folder contains 59 items, including 10 subfolders. All files and folders show a December date.

Following the path C:\Users\rsuth\AppData\Roaming\Thunderbird\Profiles\, in addition to ab3x…, there is another folder nlys3gkl.default that contains only 1 file, times.json.

Because of my earlier struggle – and eventual win – with the Firefox problem, I think that the Thunderbird problem might also be fixed in a similar way: Profile.

Slightly before the upgrading from W10 to W11, I made a copy of my Thunderbird folder. I think if I replace the currently active Thunderbird folder with the one I have saved, my Thunderbird problem may be over. However, I’m not certain that will happen and I’m not certain about the specific steps to take to make the replacement. (With my Firefox issue, there were a couple of small important steps I had to take to make it work, and those steps were explained to me by the person who helped me with my Firefox problem. So, after all these words, can someone point me in the direction to solve my Thunderbird problem?

Thanks for reading.

I'm trying to transfer the Profile folder from my current laptop to my new one. I followed the directions here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer but must've made a mistake because none of my many Local folders have populated Thunderbird in the new laptop. Also, the GB size, number of files and number of folders show to be very different on the new laptop vs. the current one.

I'm inclined to just start over but have a question. Can I simply delete the contents of the "Thunderbird" folder under "Roaming" in my new laptop and try again to paste into it? Or are there some items in that folder that were inserted when I first downloaded TB into my new laptop so that doing a complete deletion would remove those and they wouldn't be replaced when I try pasting again? If so, how do I get around that?

Thanks very much for your help.

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

I know that typically mozilla does not put a low bound on advisories, and https://www.mozilla.org/en-US/security/advisories/mfsa2024-40/ is the advisory for vulnerabilities fixed in ESR 128.2. CVE-2024-8387 is listed here. yet the advisory for 115, https://www.mozilla.org/en-US/security/advisories/mfsa2024-41/ does not list this vulnerability. Was this something that was only impacting 128 (for the ESR builds) or is there a mistake that either 115.15 did patch it but it wasn't documented, or the patch has been missed and ESR 115 is still vulnerable?

It seems from reading on forums and googling that there is a "return receipt" function in Thunderbird. My problem is I can't find it anywhere in my software. I've searched in every category and can't even find an "Options" on the menu. I remember when Thunderbird did have a "return receipt" that was very easy to find. Now it seems that it has disappeared altogether. What gives?

I have a custom pitch black theme ( pls add it without addons ) which now only flashes for a second when i open the browser and returns to the normal greyish dark mode. When i go to Firefox Color addon page and load it again in saved themes it stays pitchblack even if i open another browser window until i close all the browser windows .

Dear Sir or Madam,

I need your help.

My Thunderbird shortcut no longer opens. The shortcut C:/Online/Thunderbird is empty. The folder no longer exists and my Thunderbird can no longer be found after an update on November 1.

I can still find Thunderbird version 128.4.0 260MB from 1.11.24 and my old profile from 7.11. under Windows Programe.

What can I do to get my Thunderbird back? Reinstall Thunderbird and integrate the profile?

I haven't actively deleted the program and can't remember updating it.

I was just able to save the profile to a USB stick.

Many thanks in advance for your efforts

German Kann die Verknüpfung von Thunderbird nicht mehr öffnen. Diese ist nicht mehr auffindbar.. Mein Thunderbird ist wohl nach einem Update am 1.11. nicht mehr auffindbar. Finde unter Programe Thunderbird Version 128.4.0 260MB vom 1.11.24 und mein alten Profil vom 7.11. noch. Was kann ich tun um mein Thunderbird wieder zu erhalten? Neu installieren und das Profil einbinden? Habe aktiv das das Programm nicht gelöscht und kann mich an ein Update auch nicht erinnern.. Konnte das Profil gerade auf einen USB-Stick sichern

Been using TB for about 10 years. My last upgrade was to ver 52.9.0. in 2018. Since, I have clicked the upgrade button a few times. I do not know what ver I was running before my accidental upgrade to 115.16.2 a couple days ago. This ver is terrible. I want to go back to my previous ver, but not sure what it was.

So a month ago I did a win 10 backup to my external drive. Not sure how to just restore TB on win 10 backup. Also, I weekly copy my profile to a thumb drive.

1. Where is that ver number located in the copied profile so I know what ver I was running? And if I find it can I just uninstall TB and all files/profile and reinstall that version; then import my copied profile without losing 10 years of mail?

Hi,

I seem to be having a really odd issue where each time I restart Firefox, recent addons I've installed will not function or appear in the Add-On drop down menu (despite being meant to appear in such), despite being enabled and still being shown as such when I check settings. They only become visible and functional when I disable and re-enable them.

I've just discovered the same thing seems to happen in reverse too. I recently disabled ClearURLs due to a bug it was causing in Google Drive, yet it appeared in my Add-On drop down menu after restarting. Checking settings showed it to still be 'disabled'.

Things I've tried:

• Restarting both Firefox and PC.
• Uninstalling and reinstalling the effected Add-ons
• Deleting my extension*, compatability.ini and prefs.js files - erasing all my add-on settings yet still not helping. This is the main thing I've suggested on forums like this with similar questions, but has not helped.

It seems to only be effecting the most recent set of add-ons I installed over the last week, as if Firefox keeps trying to work with the Add-on settings I had at a previous date. I've seemingly had some cases where the extensions disable or are uninstalled entirely but I'm not sure this is related, as I think it only happened once.

I suspect it's not to do with the new extensions themselves, given it's effecting all the most recent ones, but I'll list the ones I've seen it effecting here regardless:

ClearURLS (not recently installed, but as mentioned showing similar reverse effects) Undo Close Tab YouTube NonStop Privacy Badger History AutoDelete Don't Accept Image/Webp Decentraleyes Xkit Rewritten Disconnect AI Grammar Checker & Paraphraser - LanguageTool &udm=14

As you can see I recently installed quite a few anti-tracker type extensions which probably overlap in function, mainly just to test them out, so it could be connected to them I guess... but seems unlikely.

Thanks, Matt

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

Hello, I have a new installation of Thunderbird (128.2.2esr (64-bit)) and am unable to discover how to set it to spell check in French. I've installed Grammalecte as suggested and then restarted the programme. However the only language option is English US.

Can you help please.

Thunderbird just auto updated and will not open. Crash report opens as the program crashes. I didnt realize it had updated until checking files. Do I need to reinstall revert back to the old ver. Please advise. Thanks

On the latest update to firefox, the browser now has a vetical tab in addition to the horizontal ones. I want to remove the vertical tabs, and ideally for it to never come back. I've searched the settings as well as the support features and can't find a way to turn it off. I am legitimately not going to use firefox at all until this issue is resolved.

Thanks

Thanks for having me . I am struggling with backing up my TB on my laptop. When i set it up i was told that the way i set it up it would need backing up regularly as it is based on my computer hard drive. I followed a youtube guide to back up but i keep getting this message: "this action cannot be completed because the file is open in thunderbird- close file and try again parent.lock "

and cannot get passed it.

Any guidance would be gratefully received. ( or another method of backing up that a simple person could follow) TIA Cheers

Hello !

I'm having an issue loading my Thunderbird profile and looking for help. I copied my profile from C:\Users\phili\AppData\Roaming\Thunderbird\Profiles to D:\Thunderbird\Profiles I updated the profiles.ini located in C:\Users\phili\AppData\Roaming\Thunderbird but it didn't work. When I launched Thunderbird, it asked to create a new profile and erased my updates in the profiles.ini

My Thunderbird install is located here : D:\Program Files\Mozilla Thunderbird\thunderbird.exe I'm running 128.5.2esr

I've tried moving back the aiedx66w.default-release to C:\Users\phili\AppData\Roaming\Thunderbird\Profiles but to no avail.

Can someone help me ?

Thanks Philippe

I have loved FF desktop browser since I started using it per my boss in 2003. But I am so tired of the fact that EVERY SINGLE TIME you put out an update it breaks my access to the bank. EVERY SINGLE TIME. I waste HOURS reading articles, calling the bank IT dept, chatting with people who are on 3 calls at once, only to hear them tell me to "just use chrome." I clear the cookies, clear the cache, reboot, follow all the prompts in the settings and THEN the damned bank server doesn't recognize the device so it forces yet ANOTHER password change. It happened again TODAY and it makes me so sad but I cannot do it anymore. I am STILL now (going on 4 hours) trying to access the billpay page @ Xantanderbank. (ahem, secure codename) I am forced now, by this craziness, to use the imbecilic duckduckgo which is A) and offensive name and b) you KNOW it nowhere near the product you have built but I CANNOT DO THIS ANYMORE. Thank you for the time it takes to read this diatribe. I appreciate it.
