Public bug reported: This morning I booted my machine and launched Firefox. I restored my tabs from my previous session, and _none of them_ displayed any content. The tabs included pins, regular sites, and extension dialogs (specifically, a couple of instances of the LastPass 2FA prompt). Further to that, Firefox menus also wouldn't display; either via right- click on tabs, or via the "hamburger" menu in the top-right. (I could still close tabs via Ctrl-W for non-pinned tabs, or via middle-click for pinned tabs.)
favicons were displayed correctly, and I confirmed that the pages were actually being fetched from the remote sites because I typed the address for a page I know redirects and the redirect happened (specifically, "!g foo" in my address bar caused DuckDuckGo to redirect me to Google). Restarting the browser did not fix this. Closing all of my tabs and restarting the browser did not fix this. Closing all of my tabs and restarting the browser, however, _did_ allow the Firefox menus to render (provided I didn't try to open any web pages before using them), which allowed me to switch "Enhanced Tracking Protection" from Strict to Standard, fixing the problem. (This is the second time I've experienced this exact behaviour, which is how I knew to try modifying the tracking protection setting.
