127.0.2 profiles in folders: "Firefox is already running"

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.

Chosen solution

Solution: this is happening when Firefox is installed as a snap instead of via `apt`. To fix it I did the following:

``` snap remove firefox apt install firefox ```

I previously had it installed with `apt` but somehow it must have been re-installed as a snap along the line.
