1661619 - `firefox --profile DIR` not loading extensions in non-default location

Status: RESOLVED DUPLICATE of bug 1429838

(Toolkit :: Add-ons Manager, defect)

Description

[denys.politiuk]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0

Steps to reproduce:

Platform: Linux
Firefox Version: 80.0

When copying profile folder from a default location (~/.mozilla/firefox/DIR) to a different location (like /tmp/DIR) and running profile from a new location with firefox --profile /tmp/DIR the profile does not load extensions correctly. Extensions show as enabled but they are not functional. Toggling extensions off/on fixes the issue, so is exiting the browser and rerunning the same command.

Steps to reproduce:

1. Copy profile folder from ~/.mozilla/firefox/DIR to /tmp/DIR
2. Run firefox --profile /tmp/DIR
3. Extensions are broken after a few seconds
4. Exit firefox and rerun the same command firefox --profile /tmp/DIR for extensions to start working again.

I have encountered the same issue in earlier version of firefox, but changing extension location in /tmp/DIR/extensions.json used to fix the issue. After upgrading to version 80 that no longer solves the issue.

Actual results:

Firefox loads but extensions gets broken after a few seconds

Expected results:

Firefox loads and extensions keep working
