[SOLVED] Firefox color theme changed after upgrade

After Firefox upgraded from 114.02 to 115 menu and tabs background color changed:

114.02:
firefox-114.02

115:
firefox-115

These are screenshots of active window. When window of v115 becomes inactive, background color changes to lighter, but still no visible horizontal line between menu and tabs.
I don't use any additional themes, "System theme — auto" is selected.
There are no changes in toolkit/mozapps/extensions/default-theme in Firefox sources between 114.02 and 115 (except whitespaces).

From release notes for 115:

For users with a Firefox Colorways built-in theme, the theme will be automatically migrated to the same theme hosted on addons.mozilla.org for Firefox profiles that have disabled add-ons auto-updates. This will allow users to keep their Colorways theme when they are later removed from Firefox installer files.

But i never used Colorways and don't know what is it.
I use Fluxbox window manager, if it matters.

Is there a simple way (not creating own theme trying to choose similar colors) to get colors and behavior on activate/deactivate back as they were in 114.02?

UPD: There are changes between 114.02 and 115 in `browser/themes/`. So the question becomes: is it possible to "extract" default theme from 114.02 and somehow convert it to be used in 115?

Re: [SOLVED] Firefox color theme changed after upgrade

Same issue here, but xfce + xfwm.

115.0.1 (64-Bit) firefox-bin downloaded from mozilla.org works as expected for me.
I don't have a browser/theme folder.

I am using adwaita dark as gtk theme and firefox is configured to use the system theme.

This are my looks:

copied the files from ~/Downloads/firefox to /usr/lib/firefox but without success.

Re: [SOLVED] Firefox color theme changed after upgrade

I had the same issue with XFCE and Adwaita Dark.  Performing a 'Firefox Reset' fixed the issue: Firefox menu (the button with the three horizontal bars) --> Help --> More troubleshooting information --> Reset Firefox.

(https://support.mozilla.org/en-US/kb/re … -settings#)

Be warned: resetting Firefox will nuke most of your custom settings and delete any extensions you may have installed.  Be sure to make a backup of your ~/.mozilla directory and/or write down all your installed extensions so you can reinstall them after the reset.  You'll also want to go through all of your firefox settings to make sure everything is to your preferences.

The issue appears on newly created profile too. "Refresh Firefox" doesn't help.

Re: [SOLVED] Firefox color theme changed after upgrade

Got answer with solution on Mozilla support site (https://support.mozilla.org/en-US/questions/1417606)

In Firefox profile directory create file chrome/userChrome.css with following content:

vbox#titlebar {
   background-color: InactiveCaption !important;
}

tab.tabbrowser-tab {
  border-top: solid #ccc 1px !important;
}

In about:config configurator page set toolkit.legacyUserProfileCustomizations.stylesheets option to true.
Restart Firefox.
