I have used version 145 of Thunderbird "all my life". Until the other day when I installed version 146. I realize of course that development changes things, but I would like to inform you that a 93-year-old has neither the patience, energy or interest in learning the new Thunderbird. I therefore wish that someone would be so kind and send me the installation file for the previous version. (Unfortunately, my own one is in a computer that I no longer own.) Furthermore, I donated 194 SEK on December 26th when I downloaded the program. (And it wasn't the first time.) In summary: I would like to get the installation file for the previous version (for Win11, 64 bit). Best regards Hans Peter Wiehen

Hi there. i have here one chinese tablet and i want to install it firefox but cannot login to Google Play store because i see error for the browser. i want install it firefox and set firefox as default so i can log into Google play store.

thanks in advance

Current version of Firefox has

    (1) popups to get me to download a new version,
    (2) tab pickup,
    (3) popups to show
    article titles,
    (4) popups to show
    current URLs.

I just want to download the install programs until I get the most recent one that has none of (1) - (4).

I need to go back 1, 3, 5, 10 years?

So where on the Internet should I go to get such an old Firefox install program?

I used to really like Firefox, but changes (1) -- (2) have ruined it for me.

Hello During installation, Thunderbird Release does not give the option to choose a folder on a network drive, such a NAS network drive. So, how to install thunderbird Release on a network drive ? Thanks

No FireFox icon on desktop. How do I access the search engine? I DO have the icon for Adobe Acrobat, which I got for FREE at Firefox. When clicked on only gives Adobe site.

I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

I have downoloaed Firefox offline installer (a .xz file) from here:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/139.0b9/linux-x86_64/en-GB/

I have also downloaded a .asc file, presumably a pgp signature.

Now both files are saved locally in my computer.

Assuming Linux latest release, how do I verify the contents of the offline installer file (.xz) from the Linux Terminal? I have install gpg tools. And commands like ```gpg``` are available.

What I did so far:

 gpg --show-keys --with-fingerprint firefox-139.0b9.tar.xz.asc

with this output:

 gpg: no valid OpenPGP data found.

Do you really want us to verify the contents of the installers you provide? A sha256 sum would be great, though not as secure, for when the GPG predictably fails for the ordinary user due to its huge and useless complexity and bureaucracy.

I have a dual boot Windows / Linux Mint dual boot pc with the profile on the windows drive. I have Thunderbird installed on both and the Linux Thunderbird linked to the profile on Windows. This has up until now worked for me. The Windows Thunderbird is on the esr channel (140.0.1esr) and the linux Thunderbird is installed from the software repository. I'm guessing the two Thunderbird versions on Windows and Linux have gotten out of "sync"? Now when I use the Linux Thunderbird I get the message that the profile has been modified by a newer copy of Thunderbird (the last update on on Windows).

UbuntuHandbook.org details how to install Mozilla Thunderbir via ppa.

I would really like to access my emails from both operating systems.

Can I install Thunderbird via the ppa command to get the esr client over the top of the existing Linux Thunderbird or should I uninstall the existing package first? Do you guys think this will work? Thanks in advance.

[Note: I characterized this question as an "Installation and updates" issue (even though it is not per se about initial installation or updates) because moving a profile involves installation issues.]

Recently I moved my TB profile, for the second time in the past few months. This time I paid closer attention, and noted several things of interest (that may touch on some questions that remain undiagnosed in this forum):

1. TB took longer to start up, as it could find none of the folders cached in folderCache.json, so rebuilt the cache from the new profile location before starting. (I only learned about this from the next effect.)
2. The "Move to" "Recent" folders list was empty; this cached list only gets rebuilt from use (that is, from moving messages manually (not via filter) to destination folders). This effect led me to folderCache.json- and also may suggest why the OP in that question could not get resolution of his problem.
3. The newly cached folderCache.json was 528 KB, compared to 365 KB at the old location -- and that, in turn, was 170 KB larger than the 195 KB size of folderCache.json at the original location. So each time the cache is rebuilt it grows perhaps 150~200 KB (size depending on the many-times-repeated path length).

What causes the file growth? Because each time it is rebuilt, TB checks through all of the cached folder paths, apparently guided by the mailboxes listed in folderTree.json (see image below). [I think TB just checks each path to see whether it is compatible with the current profile location. If yes, the path is cached for runtime; if no, the path is repopulated from the current profile location (which takes most of the startup time).] But TB never deletes the no-longer-valid paths; it just appends to what was already in the file, so that the list of cached folder paths just grows (thereby increasing TB's startup time, every time). The best way to get rid of the old stuff is just to delete folderCache.json and let it rebuild on the next startup, to reduce the time needed for subsequent starts.

Finally, my questions: In addition to folderCache.json (different timestamp in each profile, of course), there are four files which are the same in all profiles: folderCache-x.json, x={1,2,3,4} (see screenshot). These are apparently from actions prior to the profile relocations, as they are simply copied from one profile to the next, unrelated to changes in folderCache.json. Can someone tell me:

1. What actions cause the creation of folderCache-x.json files?
2. Why folderCache.json merely appends new folder paths without deleting the old ones?
3. Why folder paths are specified explicitly (fully qualified) rather than relative to the profile path?

Thanks for any pointers.

I am professional developer and deliver Android rugged devices to professionals. I do not want to log on my personal Google account just to install Firefox via Google play. I am used to install via adb commands the apk packages. Why cannot we find the apk of Firefox easily to download ? thanks
