ERROR MESSAGE: The application “Firefox.app” can’t be opened

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.

Upgrading Thunderbird from 52.9.1 to 60.9.1

I have been running 52.9.1 because it supports all of the add ons I want. v60 also supports the same addons. v68 onwards does not. Most of them have not been replaced (because of removal of APIs for example), and have not been replaced by native Thunderbird options.

The key addons for me are minimize to Tray (yes I know it's available in 102). Security settings from address book (selective encryption - I don't have to globally enable/disable encryption for my S/Mime certs). And Manually sort folders (As I have over 400 and 52.91 does not sort them).

I also use a custom theme. I cannot use dark mode as I'm old and visually impaired and dark themes make stuff impossible for me to read.

I have a dozen email addresses. Each email account has a number of filters which move emails to subfolders on Local Folders. Basically, nothing stays in the inbox of the account.

I use pop for inbound email. I have moved my profile folder and my mail storage off the C:\ drive to simplying restoring of the C:\ drive or reinstsallation of Wiindows. Email and all Mozilla profiles are backed up twice daily using Macrium.

v52.91. is 32bit. I've downloaded the 64 bit v60.9.1

So my question is; Can I install v60 over the top of v52 and expect that Thunderbird will pick up my exiting configuration as it is now and "upgrade" any DBs or profiles or whatever such that I do not have to reconfigure everything?

Given the difference in bitness, is installing v60 going to break the ability to uninstall v52, or will uninstalling v52 after upgrading to v60 break my configuration or lose anything?

thanks for your help.

FYI: I did try 102 and 68 before asking this question. I also really cannot cope with square tabs. They just look so bad. I've never been able to get any assistance from Reddit regarding customizing the tabs on Thunderbird (or anything else Thunderbird related for that matter).

Hallo,

is it possible to automatically perform downloads in the library one after the other?

I have about 30 or 40 downloads in the list (videos), 2 to 5 GB in size, which of course take time to download. I have to start every single download individually and sit next to it.

Although I have a fast line (230 MBit per second), it still takes a few minutes for each file.

Is it possible that firefox or an addon is monitoring this list and after completing the first one downloads the next one and then gradually all the other starts?

Thanks

A month ago, I decided to give Thunderbird a try as my email client coming from MS Outlook.

I used the import functionality to import my from my Outlook installation's .pst files.

Everything seemed to work and I have been using Thunderbird for a month now.

Today however, I required to look up past sent emails. The Sent folder is there. It imported and the messages are there. Unfortunately the "From" and "To" fields have had their email addresses replaced with just the person's name. This is not consistent but is true perhaps 80% of the time.

The From field of course just has my name The sent field in most cases only has the recipient's name, though there is the rare email that does show the email address.

Is there a method to correct this?

Thanks in advance.

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 managed to import part of my messages at the beginning of the folder hierarcy and some at the end. The missing parts in hte middle, I guess is because of the large size of the folders I subsequently tried importing sub folders but it doesn't work. I get 'Complete' straight away and the import folder is empty..

I've an extensive hierarchy of messages and having to do this preacemeal will be time consuming and error prone.
