Hi! I have latest version of Firefox installed on my PC. But sometimes I am programming for web. So I would like to have Firefox Developer Edition as well. But I don't want them both at the same time - one for my usual web surfing and another one for web programming using leading (or even bleeding) edge features.

How do I install and use them separately? I tried running Firefox Dev Edition installer, but it does not ask questions like where to install and which Firefox profile to use.

When I do the keybind (Control + P) or press the print icon in google apps (google docs, drawings, etc) it automatically downloads a pdf instead of opening the print menu. Chosen solution

Printing on any other site pops up with the printing options. Only on google apps does this happen, including gmail.

This problem is non-existent on Google Chrome and Edge. It does persist on Brave although. Haven't tested any other browsers.

Browser is FF Nightly 112.0a, but this is probably a bug in stable FF, too. "Always ask you where to save files" is checked, in preferences. Like title says, the "last download location" is stored, and works for downloading files, and downloading a SINGLE item in Tools\Page Info\Media (Ctrl-I), but if multiple items are selected (in Page Info\Media), folder opened will always default to set location, instead of last download folder.

Installing root CA certificates

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.

I cannot unpin Firefox from the taskbar

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.

Hi. I was suddenly having unexpected problems to log in in a site (https://www.lanacion.com.ar/). So I updated FF but the problem persists. Then, I uninstalled FF, downloaded it again from the repository and installed again, but the problem persists. Then, I downloaded directly rom the Mozilla site, expand it in the desktop and double click the program icon. The program opened and I was able to log into the site I was trying to. Interesting enough, the browser opens a lot faster than when installed. My question is: everywhere on the web the response is "you have to install the program" or "the program is already installed in your distro", which is true in my case, but one day stopped to work properly. BUT I'm not installing it, and it works apparently well... ¿how can it be? Thanks in advance for your reply. -Enrique.

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?

Regards. Anders, Göteborgs Stad, Sweden

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?

Hello everyone,

I have a very weird behaviour with one of my Apple MacBook Pro M1 (2020) with macOS 13.3.1 and Firefox. After removing Firefox (trash + remainings in /Library and ~/Library), Firefox is gone... until I reboot. It then reinstalls automatically!

One weird thing I see in Disk Utility is an "Apple UDIF read-only compressed (bzip2) Media" that I cannot delete because it's in currently in use (see screen shots attached).

I can also see it in with diskutil list:

/dev/disk5 (disk image):

  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:     Apple_partition_scheme                        +391.2 MB   disk5
  1:        Apple_partition_map                         32.3 KB    disk5s1
  2:         Apple_Driver_ATAPI                         4.1 KB     disk5s2
  3:                 Apple_HFSX Firefox                 391.1 MB   disk5s3

There is no dmg file attached to it, I have no idea where it comes from.

My question is: how can I uninstall Firefox on this computer?

Thank you for any help, Panda

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

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?
