1446183 - Firefox custom theme keeps resetting to default on v60.0b3

Status: RESOLVED DUPLICATE of bug 1450975

(Firefox :: Theme, defect)

Description

[K Mozej]

After upgrading to Firefox v60.0b3, my custom installed theme keeps resetting to the default photon theme. 

1. Install a custom theme from AMO
2. Close Firefox wait 2-3 hours (not sure exact time but this is when I found it reset)
3. Open Firefox, theme reset to default one

However if I install a theme, close and reopen Firefox within only a few seconds/minutes the theme doesn't reset. It seems if you don't open Firefox for a few hours then open it up again the theme gets reset.

I have the same problem when update to a new version.
Open a instance very long time and reopen it also have probability to meet this problem.

The only solution is remove and reinstall the theme.
Disable then enable the theme can't restore.
