Hi! I am a tax accountant. Considering updating from Thunderbird 97.0b3(64 bit) to latest non-beta version. Is this feasible? Is there a separate/special update process from Beta to the latest? Also would like to continue to use my POP account set-up at Optimum(Cablevision) here on Long Island. Email (Outbound)SMTP and (inbound)POP mail servers have to remain the same. So initially , I have to backup all my existing Thunderbird data & Profile.

I have used Thunderbird for a long time; previously used Eudora. The problem which I am trying to prevent is that when I try to send a client their encrypted PDF of their tax returns and related instructions, etc. my document database or data magt system, namely File Cabinet Solutions show in the activity log "Waiting for user input" --- so no email is created which would have all the requisite documents attached. The last time helpful client send feature worked in my tax software, Ultratax, was June 27, 2025. Ultratax could not figure a solution, after several weeks & suggested that I upgrade my Thunderbird.. Can anyone help?

Thank you! Best, Mike Porcari--- [edited phone# from public community support forum] (cell)

i AM SHOWING 2 FIREFOX ICONS ON MY TASK BAR --THIS HAPPENED SUDDENLY ! I checked the apps and it shows 1 for firefox which is X64EN-US 322 MB--I did not uninstall,so what can I do to solve this ?

The profile manager goes out of it's way to provide all possible options *except* the one that's needed most:

How to simply "switch" from one profile to another profile?

When a new Thunderbird installation is created, all profile operations are limited to the profiles created when Thunderbird is installed. Other profiles that are available in the right location under Users\---\AppData\Roaming\Thunderbird\Profiles\* are simply ignored without any possible, or at least obvious, route to switch to them and / or activate them. Why?

This issue is a real problem when attempting to migrate existing Thunderbird settings, mail data, etc., from one physical workstation to another. Fortunately I found a fix by grabbing the mail\pop_account folder under the old profile and plugging that folder into the new profile. Still there was additional aggravation associated with lost settings, another import / export for the calender, etc., etc.

Again, why does this have to be difficult?

Hello,

I recently updated to Firefox 130 on my Windows 11 laptop, but my Android 14 device still shows version 129.0.2. When I check "What's New in Firefox" from the Android app, it displays version 130 in the webpage it opens up. Is there a known issue with updating to version 130 on Android, or is it being rolled out in phases? Please advise.

Thank you.

Hi,

We have a few vulnerabilities identified on windows server 2012 R2 servers that has Firefox version 115.15 installed and showing as Up-to date but resolution to the vulnerabilities suggesting to upgrade to version 128ESR. As support for 115 ESR version is going to end by 1st OCT 2024. Please let us know can we expect 128ESR version for windows server 2012R2? If not what is the next action plan.

Hello, During a recent software update not long ago, I lost my entire Spell Check ability and Dictionary's won't even load anymore. I figure I need to delete the program and reload, but I'm afraid of losing all my folders that have been created over the years of using Thunderbird Mail.

Could someone please explain the procedures for me to delete and reload without losing all my important folders. These folders have years of important emails stored in them.

Thanks a bunch!!

I installed Thunderbird v128.2.0esr to a new laptop and cannot find the table view/card view icon for configuring the message list and its columns. There is no longer any icon next to the quick filter bar, it seems to be gone in this version.

The Internet told be Thunderbird is the best way to Download Linuux Mint Cinnamom. I am 94 years old and cannot figure out how to do that. Can you give me detailed steps I can take to do that?

I had a problem with a new upgrade for TB and was asked by another moderator on this site to update my version of TB (128.1.1esr 64-bit) to v128.2. My version of TB did not recognize the need for an update and so I downloaded and installed TB 128.2. It successfully installed as an upgrade but in a wholly different folder under C:\Program Files\MozillaThunderbird. The previous instance of TB, 128.1.1, was installed in a different location under C:\Program FIles\WindowsApps\Mozilla Thunderbird. Under control panel I see only one instance of TB and that is the new v128.2. Under Windows Settings, Apps and Features, there are two instances of TB.

Both instances appear to be seeing the mail profile so the only thing I want to know is if it is possible and how to remove the old version of TB without losing the mail profiles. Or do I uninstall the new version and roll back? In any event I do not want to lose a mail profile with years of information.

What will happen if I reconnect Thunderbird to my email account after being disconnected for almost 2 years?

I had to switch ESP's a couple years ago and have been using their web based email platform since, but a recent outage made me realize I should have on off-line platform again, and I really liked Thunderbird.

When I reconnect, will all the emails from the new ESP download to the inbox on Thunderbird all at once?

Thank you.

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

A recent Thunderbird update (auto update) must've been interrupted, because I keep getting a "Reboot your computer to complete the update" message. I have rebooted many times with no change. I tried to uninstall Thunderbird, but get the same message. I also tried to reinstall it, but no change. The Thunderbird icon has also changed to a computer with a disk in the front. Any ideas??

i am not a computer knowledgeable person, as I am 84 years old, and do not understand or know how to make the changes that are constantly being made. Please help me make sure everything is set up correctly for the current rules and that the computer is secure, as I discuss monetary issues with many of my clients. When directions are offered, I often find it impossible to follow them, as whatever they tell me does not show up, or is not found on my screen. I have a relatively new computer, maybe a year old, so i am sure the problem is with me, and not the computer.

Thanks for any help you can offer. From past experience, please have someone with lots of patience, or some one that can just et it set up right. Thanks, Bette :>)

We've got around 2000 AD-joined windows 10 boxes, with TB as the mail client, for years. Users are connected as domain users (ie, non-admins). Now IIRC, first TB version installed was 60. TB was updated throughout the years automaticall without a hitch, up to and including version 115.x.

With the advent of 128 we had started receiving calls from users stating that a message pops-up asking for credentials. Taking a closer look we discovered that each and every installation needed admin credentials to be able to do the upgrade to 128.

Is this a bug or normal behaviour? It is definitely a problem, especially for small organizations that do not know how to install manually an MSI of the latest version.
