1768499 - Firefox fails to remember value of "browser.theme.toolbar-theme" when closed and re-opened

Status: RESOLVED DUPLICATE of bug 1768229

(Firefox :: Theme, defect)

Description

[hevinroyal]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:100.0) Gecko/20100101 Firefox/100.0

Steps to reproduce:

(1) I have been using the theme "Blue Mozilla Firefox" from Author "karoglan" for over 5 years
(2) All this time, I have always used this theme in combination with a light environment, to my satisfaction
(3) Starting v96.0 (up until the latest current version), I am being deprived of this light environment
(4) A dark environment is being forced onto me across Firefox, as follows:
. Background of main drop-down menu (Containing "Sync and save data", "New tab", "Print", "Settings", etc)
. Background of right-click menu (Containing the refresh icon, "Save page as", "View page source", etc)
. Background of "Please enter primary password" menu
. Background of auto-filled user name and password menus
. Background of elements in a bookmark folder
. Background of Downloads menu
. Background of Print menu
. Background of "Clear all history" menu
. Background of "Find on this page" menu
. Background of "You are about to close X tabs" warning menu
. Colour of title bar for "About Mozilla Firefox" window, when the window is not currently active

Actual results:

(1) As recommended by contributors, setting "browser.theme.toolbar-theme" value as "2" appears to fix the issue as long as the current Firefox window is open
(2) Now, the issue is that whenever Firefox is closed and and re-opened, it fails to recall the value of "browser.theme.toolbar-theme" and always reverts to "0"

Expected results:

(1) Firefox should correctly remember the value defined by users (in my case "2")
(2) Users should be given the freedom to set this value as per their convenience, regardless of whether:
. Firefox "thinks" that the theme is best suited for a dark environment ("What Firefox thinks" and "what users want" should not be mutually exclusive conditions)
. The theme is still being updated by the designer (I find this theme perfect and do not wish to be told to select another one)
