Hi

I would strongly recommend against making changes in about:config as it can make the situation worse.

Do you have any add-ons installed in Firefox?

@Seburo Normally I would be very cautious in about:config, but entirely disabling developer tools took away something I will never use. I haven't done any harm. I just traded the aggravation of that box constantly popping up for it bugging me with that tab. An increase with how often seems to be after replacing my favorite mouse. The wheel is stiff & the shape of it is causing me to keep right clicking & hitting menu items unintentionally. I don't need the tools. Why would I need any devtools setting true if I don't have any idea what anything I see in that box is? Please just tell me how to stop that tab asking me to enable the tools.

If you want to disable the developer tools then use:

• about:config => devtools.policy.disabled = true

@cor-el Thank you. That works. Even pressing F12 does nothing. I had not noticed the .disabled option. I just went though as a few dozen devtools options quickly & figured I would cripple it by setting everything to false. I have a suggestion. For those average users that just want to get rid of something they have no use for, maybe you could just put an easy option in Edit > Settings. There are a lot of users with even less skills than me.
