Esta excelente, cumple la función de bloquear el acceso a las configuraciones, pero no del todo. Si me voy a la pestaña ayuda, hay una opción en la que me permite reiniciar firefox, pero sin complementos, esto inhabilita cualquier restricción que se le haya echo al navegador, quizas sea bueno bloquear de alguna forma esa opción. SALUDOS SIGAN TRABAJANDO ASI

I am so happy this is available now for the newest Firefox. It keeps my autistic adult son's Firefox well locked down, and prevents him from downloading installation files of Windows software for his Linux machine!

Block downloads don't work!!!

No response from the developers.

A extensão mais útil de todas!!!!! sem ela meu cybercafé estaria desprotegido, obrigado ao desenvolvedor por atualizar e manter esta extensão, eu aprecio muito este trabalho !

the only downside is its preventing me to play my facebook videos...

Not worked correctly. For url "about:preferences" - access denined, for url "about:preferences?entrypoint=menupanel#sync" - welcome!

This extension can easily be deleted by going to ~/Users/USERNAME/Library/Application\ Support/Firefox/Profiles/PROFILE/extensions/ on mac, and deleting the extension. And if you are thinking about telling me to set it to read only, you can boot the computer in single-user mode and restart the setup process, to create and administrator account to delete the file.

THANKS A LOT BROTHER I HAD BEEN LOOKING FOR SUCH ADDONS FOR LONG TIME. I WAS LOST

I was waiting for this addon since long. the day Firefox was updated to new version the Public Fox was not working now after few months i got back this beautiful piece of app.

Good Addon!

Would recommend the addition of a whitelist!

The extension will work, but once it blocks something, it does NOT allows me to unlock!! I put the password but doesn't respond.

DO NOT INSTALL IT, until properly fixed! It will lock you out of your own system!

By the way, the addon description reads «Bookmarks», but there's actually no way to lock the bookmarks.

[Tested on Firefox 58.0.2 (64 bit), Linux Lite 3.6]
