Hardware: iMac 5K, 27-inch, 2017 macOS: Ventura 13.2 Firefox: 109.0.dmg File Type: Disk Image

For an unknown reason my Firefox browser locked up in the middle of a session. A full system re-start failed to fix the problem – all other software Apple Safari, Adobe Lightroom & Photoshop and Microsoft Office etc. continue to work as normal. Both Bitdefender and Malwarebytes full system scans have failed to identify any security issues.

To remove any possibility there was a macOS issue I successfully recovered the operating system from the mac in Recovery mode.

As the Firefox app would still not respond to the normal app opening process I removed the failed app from the mac “Applications” folder using the AppCleaner app and downloaded a new Firefox app file from the Mozilla Firefox site. I then dragged the downloaded file to the mac “Applications” folder and while holding the control key Ejected “Firefox” from the menu - the “Firefox” named disk icon on the mac screen and showing in the Finder “Locations” disappeared. Following this I successfully dragged Firefox from the “Applications” folder to the dock.

When the Firefox icon in the dock or in the Applications folder are selected the error message appears: The application “Firefox.app” can’t be opened. Repeated deletion of the Firefox app from the mac, restarting the mac, re-downloading the Mozilla Firefox app etc. etc. has resulted in the same failure. In the interim I am using Safari for the web but want to resume using Firefox asap due to Safari’s limitations.

Am I missing something in the Firefox installation procedure or there is an unrecognised security bug in the system? This is the first time I have had any issue arise with a Firefox installation process on either Windows or Apple systems.

Grateful for any advice.

Firefox Profile Lost in Upgrade

Hi,

I have just upgraded to the newest version of Firefox in the Ubuntu 22.04 LTS Repository. I'm running LXLE Linux, a Debian derivative.

I ran

sudo apt-get update

to update my sources, and then ran

sudo apt-get upgrade

to execute the system upgrade.

After I upgraded, I started Firefox, and all my history over 6 months, my passwords, and my profile settings were obliterated to a stock Firefox install.

How do I access my old information? I have lost passwords. I cannot access business information or email. I have tried searching for profiles using about:profiles, but I have only one - the default. I have also searched in the .mozilla/firefox folder in my home directory, and I find profiles.ini in that folder. However, there are only two profiles, and I tried setting Default=1 for each of them and then starting Firefox, but with no different result. The new installation of Firefox launches.

In my /home/deadpool/snap folder, I have firefox, and multiple versions, or so it seems. I have this:

deadpool@deadpool-pc:~/snap/firefox$ ls 2263 2277 common current deadpool@deadpool-pc:~/snap/firefox$ ls -lah total 20K drwxr-xr-x 5 deadpool deadpool 4.0K Jan 31 12:29 . drwx------ 10 deadpool deadpool 4.0K Jul 31 2022 .. drwxr-xr-x 4 deadpool deadpool 4.0K Jan 10 2020 2263 drwxr-xr-x 4 deadpool deadpool 4.0K Jan 31 12:29 2277 drwxr-xr-x 4 deadpool deadpool 4.0K Jan 10 2020 common lrwxrwxrwx 1 deadpool deadpool 4 Jan 31 12:29 current -> 2277 deadpool@deadpool-pc:~/snap/firefox$

It looks like there is a symlink for current to the 2077. I would hypothesize that if I set the symlink to 2263, I would see my old firefox install. Is that correct? I don't want to break my install or lose data. I'm sick of that shit.

Thanks, Nathan

I recently upgraded from 108.0.2 (64-bit) to 109.01 but it slowed my PC down to the point of uselessness. Nothing else changed application or OS-wise. PC, OS and all Apps are current & up to date. Defrag, Cache Clear a& all similar utilities run on scheduled basis prior to upgrade and everything A-OK.

Is this a Known Issue? If so, is there a fix coming
