My Tbird email was not working, so I tried a "clean re-install" as recommended on your website. I lost everything, contacts, archive, pics, email.. .years worth. Please tell me I can retrieve them.

Thank you,

Pat

Migrated my data from old MacBook to new MacBook, and got a message of a damaged Thunderbird app. Deleted the app. Thus, I cannot retrieve personal data on my old Mac. I do have a gmail account, but my preference always has ben to use Thunderbird. How do I proceed?

To get some information out of the way before reading: my verbose step-by-step is listed below, followed by a summary without the trouble shooting steps. I have read the information about managing profiles when running multiple release channels, but found it a little confusing. If I can improve the formatting here, please let me know and I will edit my post to be more clear.

I am leaving the troubleshooting steps in the event that I did something wrong here.

My questions are primarily: 1. is there a more straightforward way to do this? 2. are there any additional steps to follow after successfully getting both a Release channel installation and a Beta channel installation as far as profile management?

The problem, with step-by-step troubleshooting steps to solve I have Thunderbird Release installed on Linux Mint system-wide, following the instructions here: https://support.mozilla.org/en-US/kb/installing-thunderbird-linux#w_system-thunderbird-installation

Now I take note of the fact that beta must be installed in a different directory: "It is possible to have multiple channels of Thunderbird installed, and even run them simultaneously. Each must be installed in a different installation directory, which will force multiple Thunderbird data profiles to be used in order to protect and keep your data separated."

• ...so although I have an `/opt/thunderbird/` directory, I rename the downloaded extracted tarball `thunderbird-beta/` and move that directory to `/opt`

I move on to Step 4 from the article linked, creating a symlink.

• what I used to install Release: `sudo ln -s /opt/thunderbird/thunderbird /usr/local/bin/thunderbird`
• what I used today to install Beta: `sudo ln -s /opt/thunderbird-beta/thunderbird /usr/local/bin/thunderbird-beta`

Everything works from here as far as me being able to click on the `thunderbird-beta` executable in `/usr/local/bin` and get into the Beta application with a fresh program.

Here is the step I'm unsure of, and where I run into issues.

In Step 5 of the linked article, when I installed release: "Download a copy of the desktop file": `wget https://raw.githubusercontent.com/mozilla/sumo-kb/main/installing-thunderbird-linux/thunderbird.desktop -P /usr/local/share/applications`

...gives me a launcher in `/usr/local/share/applications`. I can edit this in a text editor to point to a different icon etc if need be, but when installing release this is obviously already configured.

So when I install beta, I don't want two of the same icons representing different Thunderbird channels, because my assumption is that will cause issues. So instead of downloading this file again, I copy the file I downloaded with `wget` when installing release, and instead of naming it `thunderbird.desktop` I name it `thunderbird-beta.desktop`

• I then edit this file in a text editor to point to the Beta icon in `/opt/thunderbird-beta/chrome/icons/default/default256.png`
• But the resulting file indicates "there was a problem launching the application" and when reopening the file in a text editor, I notice none of my changes have persisted and it's blank.

...I can confirm through a file manager that the icon at `/opt/thunderbird-beta/chrome/icons/default` is a visually different icon with "Beta" added to the bottom of the icon.

So this launcher in `/usr/local/share/applications` is the step I'm having trouble with.

Troubleshooting steps:

• I delete the previously edited `thunderbird-beta.desktop` file, and I rerun the `wget` command to download another copy of `thunderbird.desktop`, this time using the `-o` flag so that the resulting name is `thunderbird-beta.desktop` again. I again edit this with a text editor and point the icon field to `/opt/thunderbird-beta/chrome/icons/default/default256.png`

For some reason, this works: allows me to save my changes and the icon of `thunderbird-beta.desktop` successfully changes to the Beta icon. By default, with no other changes, clicking this successfully launches Thunderbird, but of course it launches my Release version, so I change the Exec parameter to point to the Beta executable in `/usr/local/bin`

And now I get my desired results: start menu entry, separate icon, and launching the Beta release.

So my primary questions again are: 1. I notice that simply running the Beta application once uses the same `.thunderbird` directory that Release uses, and creates its own profile folder, which seems ideal to me. Verifying that this is the expected and preferred behavior? 2. I'm confused about the support article for profile management when running multiple release channels. Do I want to re-add all of my accounts to Beta from inside the application, therefore having two copies of my mail and profiles on my computer?

Greetings! I asked this as a "Question" over a month ago with no answers offered. Perhpas I should have posted it here:

I'd like to move the Firefox program files to a secondary hard drive without losing bookmarks, settings, etc. Please advise the best way to go about this. Win 11, Thank you.

The reason for this, if relevant, is that my C dirve is filling up and if I can move some of the files off it, it would be easier than replacing the drive.

TIA

I want to dowload V150. The current Firefox version sucks. If you don't let me download an earlier version then I will stop using Firefox because the latest version is SHIT!

Can`t install on my account [edited]@hotmail.com I just create yesterday. I can read outlook program. There is something wrong I don`t know what top do. Therese Driscoll# * Numbered list item

How do I stop this page from coming up several times a day. I have already set FireFox as my default browser, several times, but to no avail. I've careful followed your instructions. I dislike MS and have used FF for years. If this doesn't stop, I'll search for another browser that hopefully behave. I have set it on 4 computers, 2 Win 10, 2 Win 11.

By the way, the computers show FireFox twice, but only one actual installation.

Please do better!

Hello,

It was good to see on today's (2nd June '26) flyer that I can get the free Firefox VPN, excellent for my laptop. I took my previous one off because it was clogging everything up.

I am from the UK and living in Spain. I have recently bought a Firestick but cannot get any UK programmes due to regional restrictions, so I need a VPN to get round those.

Proton VPN offer a free service that I can put on to the Firestick. Their site gives you the instructions. My question therefore is, can I put the Firefox VPN onto the Firestick and if so, how? It makes sense to have all your VPNs in one place. Kind regards Mike

My apologies, but I am not good at searching documentation and Q&A history without a glossary and ontology,

That is to say every (software) ecosystem has their own culture (tacit knowledge) and language (jargon)

I want to install mail user agents and web browsers on diverse systems, from e.g. RaspBerry Pi / RiscV etc. to desktops, laptops, on-prem hardware, and multi cloud distributed virtual platforms.

It would be nice to have a subset of the same server configurations and User Interface / Ergonomics descriptions (CSS) everywhere.

Regardless of machine architecture, kernel distribution, package manager, ad nauseum.

I used to be able to do this with trusted hash verified source or binary (reel-to-reel tape) or SHA256, e.g.), and trusted certificates. (e.g. pgp)

What we used to call tarballs for source, and RC configurations per user and per (virtual) machine.

I am SICK of Jenkins / Ansible / Dpkg / apt / yum / yaml / Nix .... as well as Snap, Flatpak, etc. etc. All in incompatible versions. I used to be able to create self-extracting shell archives that Just Worked on everything from mainframes to personal computers.

I CAN compile and run and modify ancient FORTRAN, COBOL, APL, LISP, and SnoBol without these headaches. I got paid very well to do this for Y2K in 1988-1999

Please take your time answering this screed.
