On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

I have been using Firefox 56.0.2 on Windows 7 for years safely. Until yesterday. We had one of those mini powerouts, that caused problems.

My hard drive is failing and Firefox will no longer fully load, it tries bless it, but some FF files must be in the damaged sectors of the hard drive. It then locks the system. Using Chrome works fine. But some logins/passwords/bookmarks had to be changed very recently and are not stored in the chrome browser yet. I hate chrome so use FF as the main browser.

I'm thinking that if I can install a fresh copy of FF 56.0.2 in a separate folder, a separate 2nd copy of FF, and then copy yesterday mornings backed up FF profile (before the crash) I could at least copy over all the bookmarks etc to Chrome so I can have my logins etc back.

This mornings backup failed to backup some FF files, all others were fine. Firefox worked fine yesterday but failed to launch this morning.

Please help save my sanity. I know I have to move to W 10, but cannot on this computer.

Hi,

I am trying to find version 120 for Linux. I haven't been able to find specific versions on the website and it seems to make me go in circles. I need the full install and the rpm for 120. I appreciate any help.

Thanks, Mitchell

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

1. Check and Uncheck "Play DRM content"
2. Check for updates while in the addons related page.
3. Checked my hosts file which is blank
4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.

I don't have time and effort to describe the scenario as I am getting sleepy. But I have pics to describe what I have experienced. But having that experience, I felt started to hesitate downloading your installer of mozilla firefox but I nahhed it to continue installing until I successfully installed mozilla firefox.

I just concern.

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

My laptop died but I have been able to rescue the SSD and turn it into a USB connected external drive. I can see all data from my old PC.

I have tried to copy all of my User, Local Apps Data Mozilla Profile data folders to my new Laptop but the data does not appear when I fire up Firefox on the new laptop.

The old laptop folder was c:\Users|Phil, the new laptop is C:\Users\Phill {setup of new PC added a second L to my name}

Is this an issue ?

I have my saved login and password details from another browser in a CSV and would like to import them to Firefox. I initially did not have the 'Import from a File' option in the drop down menu of the Logins and Passwords tab. After following a guide that instructed to set signon.management.page.fileImport.enabled to true in the about:config page, the option appeared. However, the said option is unresponsive to any clicks. The drop down menu simply closes once the option is selected, without any other reaction.

I'm not sure if this is a related problem but I am also unable to use the Import Wizard that appears on performing Alt+F and choosing 'Import From Another Browser...' The Import Wizard window only appears with a message that says "No programs that contain bookmarks, history or password data could be found."

Firefox browser version: 103.0.2 (64-bit) OS: Ubuntu 22.04 (64-bit) Windowing System: Wayland

Funnily enough, the 'Browse..' button for adding images under this support question doesn't work either.

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!

Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

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

Can I download Firefox and save it to a flash-drive instead of installing it? The computer I need it on has a new install of Windows 7 with IE and it will not browse.

Hi,

TL:DR, Firefox 108 refuses to update to Version 109.

Firefox refused to update to 109, repeatedly said 108 was the latest version. I was sick of websites breaking so I decided to reinstall Firefox, and the website worked perfectly fine on the reinstalled one, since that app is on 109.

Unfortunately, it caused a whole host of problems since I have two Firefoxes on my laptop. When I finally got rid of the older Firefox, it worked fine…

…until I restarted my laptop. Upon launching Firefox, it crashed my laptop and when it rebooted, the Firefox reverted back to version 108 with 109 nowhere to be found.

How can I get Update 109 on my laptop? Thanks in advance.

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

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.

Hi, just bought a new laptop which is loaded with windows 11, and I cannot download Surfshark vpn, I go to google and it will not even open any surfshark page, I assumed it must be something to do with safesearch, so I clicked on the safesearch button but it does not give me the option to turn it off it just states 'You don't have permission to change your SafeSearch setting. It's locked by the device or network that you are browsing on' !! how do I get over this? any help appreciated,

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.
