Firefox Developer 80.0b7 (64-bit) Mac Catalina V 10.15.5

I've tried using the userChrome.css file to change the background color for the active tab. create chrome folder in profile folder create userChrome.css file and add: .tab-background[selected="true"] {

 background-color: #ffffff !important;
 background-image: none !important;

} Set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE Reboot mac This does not take affect and the userChrome.css file is not visible in Style Editor.

What am I doing wrong? thanks Milton

In English : Hello, I use several hundred tabs (don't judge me ^^). And I would like to be able to list open tabs like you can do with bookmarks and history. You can indeed filter and select in bookmarks and history. For example, I would like to filter all open tabs containing "foo", and select the ones I want to close among those. And not to do it one by one. Is it possible ? Thank you.

En Français : Bonjour, J'utilise plusieurs centaines d'onglets (ne me jugez pas ^^). Et j'aimerais pouvoir lister les onglets ouverts comme on peut le faire avec les marque-pages et l'historique. On peut en effet filtrer et sélectionner dans les marque-pages et l'historique. Par exemple, j'aimerais filtrer tous les onglets ouverts contenant "toto", et sélectionner ceux que je souhaite fermer parmi ceux-là. Et non pas de le faire un à un. Est-ce possible ? Merci.

Every now and then, although I have my browser set to open with all previous tabs in place, it does not, and they are lost. But there seems no way to have them reopen and I lose a lot of info this way. This is even though the settings are such that it says to open all the tabs from last time. Any answers

1. My network is disconnect. 2.Restore from previous session (restore tabs and windows) 3.My network is connected. 4.Click on pined tab. => i can not press refresh button or any button on top menus.

My solution is clicked Try again button on the page.
