I have two identical computers running Firefox on Windows 7. No serious issues for 3 years or longer.

Just recently, version 100 showed "Unknown Source" instead of the normal UAC authorization window which lists mozilla.org as the source.

The 100.0.1 update showed the same warning.

This only occurred on one of the computers. The other one does not show the warning.

Firefox worked fine after doing the downloads anyway, but the "Unknown Source" is not right and makes the user think security is being compromised.

How to migrate gmail-folders to other imap provider without duplicating emails?

Dear community,

I have been using Thunderbird for many years and simply love it. (Now running v. 91.9.0, 64-bit for Mac-OS monterey v. 12.3.1).

After having used G-suite gmail with my own domain name for years as well, I am now forced to upgrade to a google business offering or take my domain name email somewhere else :-(

So I signed up for an alternative provider, and have copied a couple of folders to the new email-account using Thunderbird. This works like a charm, but what happens when I copy over the AllMail folder? I believe I will then duplicate all the emails copied from the folders?

Is there a smart way of migrating from gmail to another imap-provider using Thunderbird which will take into account google obscure way of labelling emails? Or is there another way of migrating away from gmail?

Any help will be much appreciated.

Thanks, Fred Gjoertz.

I am looking for suggestions/work flows for migrating existing Mac's from the standard firefox release to the ESR version. I am looking to manage these all under 1 update cycle. A couple of current problems:

  1. On a system with the standard version already installed, I can't find a way to upgrade to the ESR version without uninstalling first.
  2. Once I would do an uninstall and then an install of the new version, I am prompted that I have launched an older version of Firefox and that I must create a new profile. How can I do this without loosing all users bookmarks, extensions, etc?

Thanks!

I use to click on PDF files and they would open and not download to my download folder. Well now every time i click on a PDF file it downloads it. I have tried every option in settings/general/apps and they still download in a folder. So I thought I would try MS edge and it does the same thing. Is it not the browser and was it in a MS update? It has never done this before. I don't want all these PDF files downloaded!

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

  • Download and install from "Download Thunderbird" link in notice.
  • Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

I have used Eudora for years, about 20 or more. Now I find myself with a dilemma. A secure email program I signed up for must have ports assigned to incoming and outgoing servers. Alas, not possible with Eudora, but possible with Thunderbird.

However, after reading several of the threads of migrating to Thunderbird from Eudora, it appears to be problematic--new addons, missing mailboxes, etc. It's hard to tell whether that's the norm or the exception. One of the threads I read was https://support.mozilla.org/en-US/questions/1228297 "Migrate Eudora mail to Thunderbird mail", which suggests starting with Thunderbird 17.0. That thread is from 3-1/2 years ago. Is this still the best way to migrate? Or is one of the Thunderbird migration tools a better and safer option.

I have literally thousands of saved emails and dozens of separate mailboxes and I don't want to lose them.

Hi all,

I've tried various solutions posted here to move my Thunderbird mail profile to a new hard drive/installation of Thunderbird, and nothing is working. I didn't have the foresight to copy the entire Thunderbird folder out before my HD had to be replaced, and I just copied the individual mail folders inside the Profiles folder (which always worked in the past). Now, no matter where I past them inside the new installation (whether it's AppData > Roaming > Thunderbird > Profiles) or some variation thereof, I either get nothing upon launching TB, or I get empty folders where my emails used to be.

I'm desperate to recapture these emails - I launched a new business last year and all the track record of new accounts/links are in those emails. Can anyone help me? There used to be an add-on posted here but it was later posted that that, also, is now defunct. I also have about 15 years of old Eudora emails from my existing business that I rely on for a "paper trail" that I can't afford to lose.

If there is a repair utility I can buy, I'm willing to do that. I just need to know what to do here. Thanks for any help anyone can send my way.

Downgrading from beta to release, exporting account credentials, etc.

I've been running Thunderbird beta for some time, on one of my Macs. Presently at 101.0b3. It's fine, I don't have any bugs/issues, but I want to downgrade to release and keep my installation uniform.

Now, of course I've read many people do this -- they don't set up duplicate Profiles for it (guilty here).

But what I'm seeing is perhaps a need for some more portability. Namely, if someone has only IMAP accounts, would it be useful to enable export of accounts/credentials in a format that can be imported and is generally portable within the Thunderbird ecosystem?

I see there is an add-on, of unknown (to me) origin or quality -- but it only runs on an older version.

In my case, I have a handful of accounts and while I see you can individually export something from the accounts panel, I don't see any meaningful way to translate that to another version (ie: release) of Thunderbird. Granted, this is not a task that someone does every day (imagine??) but it's a thought.

I wonder, too, if there can be alternate mechanisms to store account information in a secure manner that can be portable -- ie: in the cloud, encrypted -- in a file, etc.

OK that went onto a tangent, sorry -- but as far as I can see, the only option I have is to install the release version of Thunderbird (my beta Profile backed up) and go through the tedium of manually adding accounts.

Am I missing something?


Thanks! :)

Hi,

I looking to get Firefox to open up a PDF in the browser WITHOUT downloading the file. The reason for this is because I want to bookmark the PDF allowing access to an up-to-date version of a document.

I have selected the option to ask where to the save file in the settings. I have also set the application settings for PDF to 'always ask'. So, when I open the link, I get a window prompt asking me to select 1 of 3 options: view in Firefox, view in selected application, or save. I select view in Firefox and it still downloads and opens the file.

I definitely know Firefox used to open up PDFs AS links because I have some bookmarked. Any suggestions on why this is and how to fix would be greatly appreciated.

Thanks in advance.
