Hi! Can anyone please help me restore CSS customizations, now that the latest 100.0 update has compromised them?

My CSS has always been directed to two effects:

- tabs on bottom - general transparency of the bars

The latest update luckily spared the former, but not the latter! Anyway, this time I haven't been able to solve it on my own, unfortunately...

My current userChrome is:

https://pastebin.com/96BJRyUt

And my "special" about:config settings, which I've customized over the years to set everything back to how it looked before the progressive updates, are:

accessibility.typeaheadfind.manual - FALSE

toolkit.legacyUserProfileCustomizations.stylesheets - TRUE

print.save_print_settings - FALSE

browser.download.autohideButton - FALSE

browser.proton.contextmenus.enabled - FALSE

browser.proton.enabled - FALSE

extensions.pocket.enabled - FALSE

layout.css.prefers-color-scheme.content-override - 1

browser.theme.content-theme - 1

browser.theme.toolbar-theme - 1

browser.download.improvements_to_download_panel - FALSE

browser.download.alwaysOpenPanel - FALSE

Can anyone please suggest a solution? Thanks for your attention!

I think your code for removing the toolbar haze is:

  /* Transparent toolbars */
#main-window[lwthemetextcolor="bright"] #navigator-toolbox > toolbar:not(#toolbar-menubar):not(#TabsToolbar) {
  background-color: transparent !important;
  background-image: none !important;
}


This is what I posted in another thread 11 months ago, but haven't tested recently:

/*** Theme visibility: clean haze and lines from toolbars ***/
#nav-bar, #PersonalToolbar {
  /* Remove Haze */
  background: transparent !important;
  /* Remove Line at top of nav bar */
  box-shadow: none !important;
}


Does that still work with your theme?

Thanks for your reply.

Do you mean there's a way I can get general transparency of the bars and tabs on bottom without userChrome.css customizations?

You can look at his forum response for CSS code in userChrome.css for Firefox 89+ to move the tabs to below the Navigation Toolbar.

I tried replacing that part of code with the one you suggested and it worked perfectly: thank you so much! Best regards
