1203784 - Having extensions installed revert selected theme to default one

Status: RESOLVED WORKSFORME

(Firefox :: Theme, defect)

Description

[António Novo]

User Agent: Mozilla/5.0 (masking-agent; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20150910030225

Steps to reproduce:

Using a clean/new profile:
1) Install a lightweight theme (any, example: https://addons.mozilla.org/en-us/firefox/addon/transparent-firefox/), and set the newly installed theme to be used;
2) Install an extension/add-on (any, dictionaries included, example: https://addons.mozilla.org/en-us/firefox/addon/united-states-english-spellche/)
3) Restart Firefox


Actual results:

After restarting Firefox, the selected lightweight theme as reverted back to the default one. Re-selecting any other lightweight theme and restarting has the same results.


Expected results:

Firefox should have maintained the theme selected by the user, without reverting back to the default one after each restart.



Note: this only happens with lightweight themes, the developer theme is not affected (stays in use after restart if selected).

Seems like a regression only on the last nightly release, right now it's either have no extensions, only use the default theme or have to re-select the desired theme after each browser restart.

Reproduced in nightly on Ubuntu 14.04. Theme resets itself to default on restart.

The latest Nightly build (https://hg.mozilla.org/mozilla-central/rev/039a8490891595736b16a3ccb17f025f4dcf13eb) seems to have fixed this, selected theme stays in use after browser restarts.
Can someone else confirm this, and if so close the bug?

Since no one reported anything, it seems like this is not an issue anymore.
