User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

On 2019-05-21 I updated my computer from Ubuntu 18.04 to 19.04. I'm not sure if Firefox was updated to Firefox 67 prior to my upgrade. I was not using any nightly or developer versions.

Actual results:

When loading Firefox an error window came up with the following text:
> Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox.

Expected results:

Firefox should have loaded my profile without issue.
