Frontier Secure from Frontier Communications (my internet provider) sent a 'pop-up' that they wished to modify Firefox. I closed the message without approving it, because there was no other information offered. I love my Firefox and don't want someone adding to it, or diminishing it's usability. I know Frontier will be 'upgrading' their security programs in a couple of weeks. I realize security is important. Was I right or wrong to not reply and does Firefox let me know if there has been any 'outside' changes or 'modifications' to the programs it offers?
