Hi,

To get myself off MS Edge (as its Chromium based), I've come back to FF. But after I tried installing firefox standard and even the Extended Support Release I can not run it for the first time - I get this error

Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I've followed the advice in the help pages, but it hasnt fixed the issue

https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

The same happens when I run

firefox -p

The firefox App Data folder contains no profile file at all....

C:\Users\marcu\AppData\Roaming\Mozilla\Firefox

Just

2022-11-14 12:49 PM <DIR> Crash Reports 2022-11-14 12:46 PM <DIR> Pending Pings

Inside crash reports is an empty events folder, and two crash report instance files (once for each attempt to start up FF) For example

InstallTime20221104133228

The above crash file conatins

1668458789

I've tried uininstalling and wiping all files, and I wanted to try an old versions BUT the link on the page is dead

https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ - Gives me 404

Do I have some service not running that this relies on ?

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

How does one specify which program opens a .zip file after it is downloaded?

Presently, the download functions properly, but when I click on the file, VLC media player opens; have no idea why; how can I specify 7-zip File Manager instead?

Thank you. Appreciate.

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

"OpenH264 Video Codec provided by Cisco Systems, Inc." plugin will sit in the "will be installed shortly" status forever if you have HTTPS-Only mode enabled. I have been pulling my hair out for the last few days trying to figure out why I couldn't play YouTube or many other sites videos.

Turns out the site that the library is downloaded from has a bad certificate installed: https://ciscobinary.openh264.org/libopenh264-2.3.0-linux64.6.so.bz2

``` Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for ciscobinary.openh264.org. The certificate is only valid for the following names: a248.e.akamai.net, *.akamaihd-staging.net, *.akamaihd.net, *.akamaized-staging.net, *.akamaized.net

Error code: SSL_ERROR_BAD_CERT_DOMAIN ```

OS: Fedora 36 Firefox Version: 104.0 (64-bit)

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

I'm stetting up a testing environment. It's a closed environment with no access to the Internet when it's in use.

The environment is launched from AWS and consists of an Ubuntu 18 desktop and a Ubuntu Server running Apache. The desktop is able to successfully load the website, but with a cert error that the certificate isn't trusted.

When the Ubuntu Desktop launches, it has a fresh install of Firefox, and therefore all the directories in the users home folder are not yet setup for Firefox, including the database where the root CAs are stored.

I'm am able to add the Root CA certificate into the Firefox cert database AFTER the machine fully boots and I run Firefox for the first time. I'm using the 'certutil' package to do this. After I load Firefox, then add the root CA certificate using certutil, I'm able to load the website without error.

I need to add this certificate to the database with the startup shell script for the machine.

Any help is greatly appreciated. Here's the commands I'm using:

1. copy the CA cert into firefox

export ffcerts=`ls /home/testuser/.mozilla/firefox/ | grep default-release` sudo certutil -A -n "testcert" -t "TC,," -i /home/testuser/certificates/testcertCA.pem -d sql:/home/testuser/.mozilla/firefox/$ffcerts

These commands work perfectly after Firefox is run for the first time. I've even tried adding 'Firefox' (with several different switches) into my startup script without success.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

With the release of the new ESR version, version 115.x.x, the install creates a shortcut in the Windows Start Menu called "Firefox Private Browsing". How can the creation of this shortcut be prevented during install?

Starting today, I went to download a .pdf file to open automatically with Adobe Acrobat as I usually do. However, this time I got a pop-up from Microsoft Word stating, "Word will now convert your PDF to an editable Word document. This may take a while. The resulting Word document will be optimized to allow you to edit the text, so it might not look exactly like the original PDF, especially if the original file contained lots of graphics."

I went to Settings - General - Applications, went down Contents list to Portable Document Format (PDF), and tried the various settings under the Action column, to include "Save File," "Always Ask," "Use Acrobat Adobe 2020." None of these worked or made any difference. I open numerous .pdf files every day and I need to be able to just click on them in the website and have them open in my Adobe Acrobat program - as they have up until today. What do I have to do to fix this? I am using Version 102.0.1 (64-bit).

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

I'm trying to move to Firefox from Microsoft Edge on Linux. When I go to import data from another browser Edge is not an option. I have a CSV file that I exported from Edge. How can I import this CSV file? I found something on reddit that said to change security.allow_eval_in_parent_process to true, but that no longer works. How can I get my passwords imported without having to install another browser and import to that and then import to firefox?

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

Where can I get Firefox 52.9.0? There was a list of old versions here but now I can't find it. I found https://download2.portableapps.com/portableapps/FirefoxPortableLegacy52/FirefoxPortableLegacy52_52.9.0_English.paf.exe I really did not want the portable version but avast considers it a threat so it may not be genuine.

How do I uninstall the Firefox icon from the taskbar? The standard article on the Firefox Support website is `How to pin and unpin Firefox from the taskbar on Windows 10 and Windows 11', but it seems to be out of date. It says to right-click on the icon and click on `Unpin from taskbar', but there is no such item in the right-click menu any more.

I know that it became difficult to unpin the Firefox icon about a year ago. I got a new PC recently and installed Firefox, but I could not remove the icon. Then realised that I should have done this during installation, by using 'Custom installation' and unticking the 'Icon on taskbar' option. I searched the web for clues and found none, so I uninstalled and reinstalled, which was a nuisance.

Some months later, I have just installed the new version 110.0.1, but I forgot to use 'Custom install', with the result that the icon is back on the taskbar. Again I have searched the web, and again no success. I tried reinstalling V110.0.1 on top, using 'custom install' this time --- I could switch off the 'Icon on taskbar', but the icon is still there.

I don't want to uninstall-reinstall this time because I have now configured Firefox as I want it, so that would waste a lot of time --- and I will probably forget again sometime in the future.

I am sure that Firefox has not done this deliberately, because they are always so much on the user's side.

QUESTION: How do I unpin the Firefox icon from the taskbar without uninstalling? I have an idea that there is a registry hack that will achieve this.

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

Hello, trying to verify the integrity of firefox-118.0.1.tar.bz2 I realized the GPG key has changed.

The following blog post details the change and shows the new key: https://blog.mozilla.org/security/2023/05/11/updated-gpg-key-for-signing-firefox-releases/

But when I download the key using the link provided (which points to keys.openpgp.org) the key I get is different from the key posted on the Mozilla blog page.

What is even more strange, is that the key from keys.openpgp.org declares in the comment that 14F2 6682 D091 6CDD 81E3 7B6D 61B7 B526 D98F 0353 is the fingerprint of the key (the same that is posted on the Mozilla blog) but it can't be because the key different.

So my questions: 1) Why Mozilla is posting a link to a key that is different? 2) Why keys.openpgp.org shows the correct fingerprint with a different key?

And, in the end, which key should I trust and why.

Thanks.
