All screenshot options disappeared
There is no way to take screenshots in my firefox browse. It is not an option at the tool bar nor it works by pressing ctrl shift S. So, it just vanished. What happened? How can I fix it?

Make sure that Screenshots isn't disabled if it happens again.
You can check these prefs on the about:config page.
- extensions.screenshots.disabled = false
- screenshots.browser.component.enabled = false
Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

It is possible that your firewall or other security software blocks or restricts Firefox without informing you, possibly after detecting changes (update) to the Firefox application. Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access for Firefox and the plugin-container process and the updater process.
