Has anyone had any uBO problems in Firefox (macOS)? The icon disappeared from the GUI and I couldn't access certain sites. It was still in Extensions so I've uninstalled it and replaced it with ABP.
see, this is why i always run portable browsers on my rigs. corrupted profile? easy peasy. delete the app folder, start using a fresh profile with the exact settings and extensions in just seconds. i keep a customized copy of my portable apps as a backup so i can use them when need be.
