Firefox 96.0.2
When Firefox 96.0.2 was installed on my Windows 10 computer my bookmarks tab went from white to black. The only way that I was able to get the white back was to change my Firefox Persona.
I would like to be able to use my previous Firefox Persona but until a fix is produced I have to use a Persona which is not my preferred choice.
This is both a request for help and information to those looking for a short term fix.

You need to use a theme with a light text color on the toolbars (tab bar) to prevent Firefox from switching to dark mode.
You can change this pref on the about:config page from 3 to 2 to revert to the Firefox 94 behavior regarding to prefer dark or light background for webpages.
- layout.css.prefers-color-scheme.content-override [dark:0, light:1, system:2, browser:3]
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
