hi I would like to download and install firefox for android which if I understand correctly is named fenix, without going to an app store. I don't see a direct link on the main pages on the website. I noticed at https://archive.mozilla.org/pub/ it looks like it might be possible to get the apk. My concern would be does this violate any terms or licenses? Is this 100 percent ok to do? Also does the firefox owners have anything written answering this? There are websites that imply sideloading firefox might be considered using without permission and I definitely don't want that.

I have a new HD and installed Linux Ubuntu 24.04.1 LTS. I installed Thunderbird version 2:1 snap 1-Oubuntu3. The program will not open Just get "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

Greetings to all, I'm trying to install the Thunderbird email client on a Mac that is running High Sierra. I have downloaded the installation package 3 times from the Thunderbird.net website but each time I try to open one of the .dmg packages I get an error that states the image is corrupt and cannot be opened. Is there something I'm doing wrong?

Hello,

I received a new laptop with Ubuntu 24.04 and I'm trying to install Thunderbird. I have tried snap, flatpack, the downloaded package and nothing works. The only one that worked so far is https://www.omgubuntu.co.uk/2024/08/install-thunderbird-deb-not-snap-in-ubuntu-24-04 but this results in a different (?) thunderbird being installed, thunderbird-esr and there is no icon in the dock and I cannot pin it in the dock, which is a bit annoying. I saw there are other people having the same issue as me https://ubuntu-mate.community/t/cannot-install-thunderbird-because-it-is-not-allowed-by-dot-thunderbird-plug-rule/28878/13 https://askubuntu.com/questions/1538919/ubuntu-24-02-error-installing-thunderbird

The command `$sudo snap install thunderbird` gives the following error `error: cannot perform the following tasks: - Mount snap "thunderbird" (609) (installation not allowed by "dot-thunderbird" plug rule of interface "personal-files" for "thunderbird" snap)`

I also tried various commands offered in response to the questions linked above `$snap connections thunderbird` returns `error: snap "thunderbird" not found`

`$snap interfaces | grep personal` returns `119::personal-files firefox:dot-mozilla-firefox 'snap interfaces' is deprecated; use 'snap connections'.`

`$snap version` returns `snap 2.67 snapd 2.67 series 16 ubuntu 24.04 kernel 6.8.0-51-generic`

`$snap list --all thunderbird` returns `error: no matching snaps installed`

I also tried via the Ubuntu "App Center" and the Install button just keeps coming back. I expect it's running into the same error I have via the terminal and doesn't give any feedback in the graphic interface.

Please let me know what I must do to install Thunderbird via snap.

Thank you, Caroline

I've tried disabling it with the secret menu and it makes no difference. Seeing as Mozilla don't give a singular toss about the needs of their neurodivergent users I want to install an old version of firefox for android with a version of the UI that doesn't make me want to self harm. I know how to disable android updates but not install an old version safely. How do I do this?

Attached a screenshot of the new UI. As an aside if anyone can recommend the drugs that the people who designed and approved this ugly tosh are on I'd love to know what they are, must be good stuff for them all to make decisions this asinine.

Mozilla has announced that:

> Beginning with Firefox 144, the minimum supported Android version will increase to 8.0 (Oreo)

Where can we download version 143 to install on older devices (Android 5 to 7) from now on?

This has been re-posted. In error my first post said ‘Firefox’ NOT ‘Thunderbird’.

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Thunderbird mail on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Thunderbird on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

Please send me a link to revert my Thunderbird version to one that supports image attachments resizing. Current version does not and there is no compatible add-on for it.

[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 trying to find the Thunderbird app so I can bypass SurfShack VPN The latest version of Thunderbird is installed and working but I can't find the executable SurfShack does not show Thunderbird as an application it can bypass

I donated and installed thunderbird on my laptop last week. I have donated twice more in the last few days to install thunderbird on my android phone in the last few days unsuccessfully. I do not know what I am doing wrong. Can you help me?

Thank you very much for taking the time to read my question.

i am using firefox ios. I would like to install the official Ublock Origin extention from the official Firefox extention site. It will allow me to press the "Download" button, but then it will open a page that says,

"Almost there! Now finish installing Firefox."

I am doing this in the official Firefox browser App, so I'm sure you can understand my confusion seeing as I am already here and I downloaded the App a long time ago. It is my default browser, I do not have any other browsers installed on this device and I never have.

Beneath the previously mentioned quote there are two blue hyperlinks. The first is labeled "Get help with your installation." The second is labeled "Download in another language or for another operating system."

It will not present any other options to me, and it will not install any extentions even if they are official and Mozilla approved. Firefox doesn't seem to be able to detect... well, itself. I have no idea what I should do to fix this. I'm sure its likely a simple solution that I am just not aware of or something like that.

in some linux (arch 32 bit) I have problem executing firefox, Is there a version for CPU without request from SSE3 Flag?

thanks

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

Madam/Sir

Please let me know if Firefox VPN is now made available for installation for Indian subscribers.

I am aware that Firefox may not have a server in India,as per our laws.

            Thanking You,

               Viraj

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.

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 am attempting to install Thunderbird on a new laptop and move personal folders from old to new PC. The installation process finds my email address and ISP information but fails with incorrect password.

Steps - 1. enter user name 2. enter email address 3. install finds correct ISP information 4. accept ISP information without changes 5. enter email password 6. process popup say incorrect user name, ISP info or password 7. login to ATT.NET successfully which indicates to me that the userid and password are correct for email account.

what other information could I supply to assist with problem resolution? I do not know what to do next.

Thank you, Neal
