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.

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.

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Support website is `How to pin and unpin Firefox from the taskbar on Windows 10 and Windows 11', but it seems to be out of date.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 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?

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

Download an APK file you want to install in the IPA format. Install Cydia Impactor to sign in to your Apple account to use the IPA file. Connect your iPhone using either a Windows or a macOS. Now launch the Cydia Impactor application.

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

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?

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?

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

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 ?

When I start firefox its stand loading for a short time, and then comes with an error that its was unable to load the window, retry or close it. No matter what wepside i enter to use its always the same. This happen a few days ago and have been troubleshooting my self since. now i need your own help. I have reinstalled it, reset settings, taking it off and on the firewall. Removed all plugins for it. and always come to same conclution. I got the latets installer from the wepside, to make sure its up to the newest version.

Before this issue, it ran fine, no issues what so ever. and one day i needed it was stuck on this problem.

I am useing it on a laptop. atm returned to chrome for help.

picture shows the issuse not able to load, no matter the wepside.

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

The download is that I am always movies on the transfer to a good comedy and show us movies because of the news , e-mailed, browser Firefox Android.install and migrate etc

Over the years I have accumulated important links in my Firefox Bookmarks bar and passwords file and it would be a disaster if for some reason my hard drive got compromised and I could no longer access them. Is there any way to copy the data to another set-up, independent of my laptop, from where the data could be retrieved in a usable form for display on another laptop or PC? Thanks.

I use debian and firefox-esr.

I have problem right now!

I used firefox version 105.0.1 for short times, then firefox transformed my profile to new version profile, so now I can't back to 102-esr version again, I have this message:

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

So i try this command to fix problem

firefox-esr -allow-downgrade

or

firefox-esr --allow-downgrade

But still can't downgrade, So I have to ask could I downgrade? else I have to wait for new esr version?

What's the next firefox-esr version? or release date?

Firefox was lagging everywhere: scrolling, switching folders in bookmarks, switching windows, switching tabs, opening settings, scrolling in settings...just everywhere. So I tried downgrading to v. 113. After downgrading via the ling in settings it still showed v. 114. I uninstalled firefox entirely and downloaded the loader for v 112. I installed it and it went thru whole install process to the point of asking to close and start Firefox. It didn't start. When I clicked on the icon it gave me a prompt that it didn't point to anything and asked if I wanted to delete it. I looked in program files folder but didn't find a folder for Firefox or Mozilla. I installed the developer edition and it worked but I don't want dark dev ed. Please help!

FF would start to load but never completely finish so I forgot & stupidly did the troubleshooting mode or w/e that put me back to default so LOST all my settings, etc.. Strangely it's back "close" to normal except I was using Passbrow which the icon shows on toolbar but greyed out & I can't get it to turn back on. I have the "Old FF Data" folder but following the steps it doesn't show where profile is stored for me to be able to copy the old data TO. IF I can restore the old profile hopefully that would get it back working ALL as it was...but HOW??
