Firefox Support Forum

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

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.

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

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.

Thanks

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

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?

Firefox 112 update will not download completely. It just keeps saying it is downloading but it does not complete. I can't access some websites now since I have been trying to download the update. Please help. Thanks.

If I want to do a 'clean' install of MS Windows - Windows 11 Pro v 22H2 (Build 22621.1485) - where are FF's sttings stored & how do I restore them after the re-install?

Hi, I received this error message today-- error: platform version '111.0.1 is not compatible with minVersion >= 111.0 maxVersion <= 111.0

I tried restarting my machine. Same error so I tried to do a refresh of Firefox and I got the same error before the refresh started. So I tried to uninstall and it won't unistall...gets the same error message.

Any ideas? Thanks Amy

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.

Windows 10, Firefox will not load URLs or settings page. Uninstalled Firefox and downloaded a new copy. Upon install system error message attached appeared but browser appeared with all my bookmarks and loading error message (attached with bookmarks erased). New pages will not load.

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 following a tutorial to install cinnamon desktop which includes Firefox snap on my Ubuntu LXD container, but the installation with snap fails. Does anyone know why it happens and how to fix it?

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.

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 installed Firefox on Windows 10, and when Firefox is running, the taskbar is blank with no icons. I just installed Firefox, logged into my Firefox account, and did nothing else.

System：Windows 10 家庭中文版 Windows Version：22H2 OS Build：19045.2673 Feature：Windows Feature Experience Pack 120.2212.4190.0

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.

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.

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.
