That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

Firefox 136.0.1, Linux 6.8.0-55, have set Okular as default pdf application, however Firefox will not open pdf file when downloaded nor will it open the file when selecting Open File from the Download Icon on the toolbar. Only was I can get to file is to select Show in Folder option and open from within Dolphin.

I am trying to reach an internal company website ([URL]), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust [URL] because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate ~~~

If i click on the error code, i get these details:

~~~ [URL]

Peer's Certificate issuer is not recognised.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false

Certificate chain:

[certificate]

[certificate]

[certificate]

~~~

If i click 'View Certificate', i get a chain of three certificates:

1. Subject common name = [certificate]
2. Subject common name = [certificate]
3. Subject common name = [certificate]

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the [certificate] certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

Hi @ all,

When using TB as a LDAP-User, logins.json and key4.db are NOT created on the (mounted) home directory.

here's my setup: Debian 12 with a local user as well as remote users, administrated via LDAP. PAM-login for local and ldap users has been setup and is working. Automounting of network drives is working. Each LDAP user has their home directory stored on a Fileserver and mounted upon login. All applications are working as intended except thunderbird.

So far I've tried to run gnupg locally instead of having it start a session from the (mounted) home directory, assuming that gnupg is the corresponding means of de/encryption. I've copied the profile of the local user to be used as the profile of the LDAP user, logins.json is completely ignored by TB.

Upon starting of TB, passwords are asked for and are remembered in the session. But passwords/logins are not stored and available for the next session.

Any ideas?

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

After latest update 136.0, a TB icon showed up in the 'system tray'. I'd like to hide it, I have no use for it. Browsing the settings including the advanced preferences yields nothing useful.

Hi, I've been a use of FF since it was Netscape (yes I'm old). And its always been my favorite above all. However, with the recent update (ver 136, either installed from a .tar downloaded or an app via apt install) it starts fine but no matter what URL I try to access the busy indicator spins but nothing ever happens. I've tried disabling all my extensions to no avail. I'm also searched for others experiencing this issue. All my other browsers seem to work well on all the same sites.

I'm kind of at a loss so if anyone has any suggestions/ideas please share?

Thanks BobMCT

When I was previously using Firefox in Kubuntu 22.04, if I downloaded something I could go to the Downloads icon and click on the download and it would open in the desired application. After a failed upgrade to 24.04 I had to do a reinstall and now in Kubuntu 24.04, if I click on a downloaded file it will always bring up a window with "Open the file link with okular?" and the buttons Cancel and Open Link below. How do I go back to the previous way of it working?

Greetings.

I am using an old Linux Mint version. I got messages that my Firefox needed to be updated.

I finally figured out how to do that and updated it. I started to use it. No problems.

However, the update did not change the default Firefox in the menu or on the taskbar panel below. If I click on them, I get the old version.

So when I restarted the computer, when I clicked on the Firefox shortcut icon in the lower taskbar I got the old version with the tabs that were on it. I had to go back into the Firefox file downloaded for the update in order to open the new version.

So, how do I get a working shortcut icon for the new version and get rid of the old version/icon?

Thanks.

David

I try to install Firefox directly from the Mozilla repository.

For that, I read the article "Install Firefox on Linux" and followed the install instructions in first chapter "Debian-based distributions" step-by-step. (article https://support.mozilla.org/en-US/kb/install-firefox-linux)

Unfortunately, with every attempt to install Firefox, the Firefox LinuxMint (Ubundu) package will be still installed. The command to priorise the Mozilla repository seems to have no influenace.

How can I prevent/avoid using the LinuxMint/Ubundu repository? I wan't to install and update Firefox direct from Mozilla source.

I'm using Linux Mint 22.1 Xia base (Ubuntu 24.04 noble)

Hello,

Moving from an older Ubuntu 18.04 machine where Firefox is limited to version 113 to a newer machine running Mint 22 where the current version is 134.

I know how to transfer the profiles but I could not find any information on compatibility.

Would I need to install other versions before 134 to handle any changes?

Thank you

Firefox 135.0 (64-bit) on Ubuntu 22.04.5. When trying to save any file (download, save image etc.) or trying to attach a file (in web-based gmail client or WhatsApp web client) nothing happens. Tried to refresh, switch off all extensions, clear download history - nothing helped. Chrome works on the same machine like a charm...

Do you have any suggestions?

Thank you

Hello,

I'm using Firefox on Manjaro. Usually I'm using dolphin but I've installed nemo too for having a second option if dolphin doesn't work. But after installing nemo the file management software when opening the folder where the file downloaded switched to dolphin. Where can I change it back to dolphin?

Firefox Version: 135.0 (64-Bit)

System Information: Operating System: Manjaro Linux KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.1 Kernel Version: 6.12.11-1-MANJARO (64-bit) Graphics Platform: X11

Recently I had un/reinstalled my firefox via snap and apt from linux. I'm signed into my account yet locally I'm not getting data to sync across devices. Any idea?

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?

I am on endeavourOS (linux). Whenever I try to upload images for a profile picture to sites like youtube or X, the image becomes corrupted and doesn't upload correctly. It did this with whatsapp too and I had to use a separate app for it. Other posts said that disabling "privacy.resistFingerprinting" would fix it, but it's already disabled.

Attached below are an example of this bug and the contents of this image when viewed on a text editor.

I know it may sound a bit strange, but I would like to know WHY an extension is not allowed in a private window, so I might understand the reason why I'm not able to diagnose an issue I'm having with fucking amazon who has their cart all over the place for a misconfiguration in firefox that either I did or an extension is causing, however I'm unable to figure out which because I can't enable extensions in private windows, where the issue does not happen, so I'm not able to reproduce and isolate the problem. Specifically, this article: https://support.mozilla.org/en-US/kb/extensions-private-browsing Plus, I was kinda expecting I could run STG in private too, since it offer such nice and rich grouping and memory management features vanilla FF does not (PS: please take inspiration and bake it inside!!) Thanks in advance.

I reinstalled thunderbird and cleared the profile folder. Then when I login Gmail, after the OAuth, it tells me "Unable to login at server. Possibly wrong configuration, username or password."

This only happens to Gmail. I also tried Outlook and this didn't happen.

I then tried running thunderbird in the terminal to see what it outputs: (image 2)

"line 232: Script terminated by timeout"

Technical information: TB version: 128.5.1-1 (arch linux aur)

Hi All,

I need open local exists files

file:///.../index_details.rst or file:///.../index_details.txt in my default system editor.

This has worked pretty well last in version 127. (https://ftp.mozilla.org/pub/firefox/releases/127.0/linux-x86_64/en-US/)

But after v127 Firefox always opens files directly (see screen). I can't find any settings to change this behavior. Something has been changed.

I keep back the firefox upgrade so long it was posible for me but 127 is now old and i use the last version 133.0-1.

I'm using Linux (Debian).

Thanks

What has happened to the "More actions" menu button - the one that normally is in the upper left corner of windows (see the attached image)?

I have just installed a new PC, with Debian 12 and KDE (plasma 5.27.5); the other windows have this menu button, but not Firefox and Thunderbird. Is there a way to get it back, eg by moving the menu bar out of the title bar and back to where it used to be?
