1900282 - "browser.tabs.allow_transparent_browser" pref should also apply to sidebar browsers

Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, enhancement)

Description

[Matthew]

Steps to reproduce:

Set the preference "browser.tabs.allow_transparent_browser" to "true" in about:config and use userChrome.css to make the browser's chrome fully transparent.

Actual results:

The browsers used by tabs is transparent, but the ones used by sidebars are not; they have a white, opaque background that cannot be removed.

Expected results:

I would like to see the browsers for sidebars also have the transparent attribute set to true.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

There is an r+ patch which didn't land and no activity in this bug for 2 weeks.
:matthew, could you have a look please?
If you still have some work to do, you can add an action "Plan Changes" in Phabricator.
