Describe the bug After copying the Firefox profile from Mint 18.3, this error occurs when launching Firefox:

Firefox msg

To Reproduce Steps to reproduce the behavior:

  1. Copy the ~/.mozilla/firefox folder from Mint Mate 18.3 to Mint Mate 19.2
  2. Launch Firefox
  3. See error

Expected behavior Firefox should start normally, as this is not actually an older version.

Frequency Does the issue happen:

Edition (Desktop environment): In which edition is this happening?

Live or post-install: Indicate if this is happening after the installation, or during the live session:

Screenshots If applicable, add screenshots to help explain your problem.

Locale: Paste the output of locale.

Drivers: Paste the output of inxi -Gxx.

Crash report:

''Stack trace'' If you are reporting a crash. Go to "Software Sources" and enable the debug symbols. Then go to "System Reports" and extract the stack trace for your crash and paste it here.

''Dmesg'' If you type dmesg in a terminal, you should see a line corresponding to the crash. Paste it here.

Additional context Firefox version in Mint Mate 19.2: 68.0+linuxmint1+tessa Firefox version in Mint Mate 18.3: 68.0+linuxmint1+sylvia

I'm reporting this in Mint Mate beta, but I suspect it would also happen in Mint Cinnamon.

I don't know if this can actually be considered a bug, or if there is anything that can be done about it, but it seemed to be worth reporting. I also know there are other ways to accomplish this, but for me, it's the easiest.

Edit: Is this because of the way the Firefox versions are named? Copying the Thunderbird profile works.

Thunderbird version in Mint Mate 19.2: 1:60.8.0+build1-0ubuntu0.18.04.1 Thunderbird version in Mint Mate 18.3: 1:60.7.2+build2-0ubuntu0.16.04.1

This is a bit weird.. the version should be considered the same. Either way, this is upstream from us.

After some more searching, I discovered the firefox --allow-downgrade option overrides the version check. Now I will have to be very careful with future Firefox updates.
