Download Firefox Ubuntu
Robinette Stiles
This installation will have priority over the Firefox version installed through your package manager. To run the version installed with your package manager, you will need to execute the binary from a terminal. To do so in most distributions, open a terminal and type:
/usr/bin/firefox
To verify that the installation was successful, you can open the Troubleshooting Information page. In the Application Basics section, the value of Application Binary should be /opt/firefox/firefox-bin.
@AliH1P well, unlocking the Linux app does not unlock the Firefox extension, and Firefox application binary is in /opt/firefox/firefox-bin. I could just set the extension to never autolock... is that a good idea? What is a security best practice?
Hello, I am seeing the issue come up again... I have to enter my master password in the 1Password application and the Firefox extension separately. This is Ubuntu Linux. sudo chown -R root:root /opt/firefox is not resolving it. I closed Firefox 114.0 and 1Password 8.10.7 before running chown. Any ideas?
Then I restarted AppArmor with systemctl restart apparmor and now the 1Password Firefox extension unlocks when I unlock the desktop app and vice versa. Solution inspired by -browser/wiki/Troubleshooting-guide#6-apparmor-with-ubuntu
Although it's probably fine to (re)take ownership of everything in your home directory, the specific reason you were unable to start Firefox is that your Firefox profile was inaccessible when you didn't run firefox with sudo.Therefore, I recommend retaking ownership of just the folder that contains your Firefox profile and other user-specific Firefox data (like your Firefox extensions):
Instead, you can use gksu, gksudo, kdesudo (on Kubuntu), sudo -H, or sudo -i when you encounter a situation where you must run a graphical program as root. However, I emphasize that running programs as root is for system administration. You might decide to run a text editor as root to edit the system's configuration files, but you never need to, and never should, run a program like a web browser or word processor as root.
I have exactly the same problem with Ubuntu 20.04 and firefox 88.0.1. When I install the Debian package 'icaclient_21.4.0.11_amd64.deb' firefox can no longer open any page, but opera still works normally. When I remove the icaclient package, firefox works immediately (no need to close and restart firefox).
The easiest way to do that is to copy the built-in one from /usr/share/applications/firefox.desktop and modify it to suit you. Conveniently, Unity will override a system-wide .desktop file if you have one with the same name in your local directory so installing it with the same commands as you did for Nightly will work fine.
As others said, this guide is broken and it would be great if it could be updated to work again. For instance, since Firefox 59 (Nightly) upgrade I think that the icon path needs to be changed from
>Icon=/opt/firefox/browser/icons/mozicon128.png
to
>Icon=/opt/firefox/browser/chrome/icons/default/default128.png
If you need to kill firefox, you can try going under System->Adminstration->System Monitor and select the processes tab. Look for firefox and right click on it. It should give you an option to kill the process. If that does not work, you might try going into the Terminal and type:
ps -efgrep firefox
In light of firefox becoming a snap, i have a tutorial on how to replace the snap version with the version from mozilla's website.
Snap firefox is fine. But if you are the person who hates the constant slow startup times, and inabillity to install mozilla extensions, you're not alone.
Note: This involves getting through a little bit of terminal, but we'll just be copying and pasting commands here. This also works with any Ubuntu flavour.
Precaution: I advice to remove the firefox snap before doing this. Only remove snapd if you don't want it anymore.
@devemux86 I'm just posting it in case a person needs a current guide. If this way doesn't work out for me or other people, I'll just use the ubuntuzilla ppa.
Also, I'm not a fan of ESR, but if that works, I'll add it to the guide.
FYI reading on IRC the mozilla team who maintain the PPA that has jammy builds for both firefox and firefox-ESR have made it clear that the PPA is not a guaranteed permanent thing. Originally said by @fossfreedom on Ubuntu Budgie Discourse.

Thanks for the report! This should be fixed in the 4.104 version currently available from the firefox extension store: -US/firefox/addon/lastpass-password-manager/. You should be able to force an upgrade in the extension management page. Let us know if you continue to see it after upgrading.
