The documents above store Firefox Agent Strings. From that list, a rule was created for each instance. Please discuss a method of creating one rule to replace all of them. What resources are available to you to accomplish this? In your opinion would this be beneficial or would the remedy to replace 1894 rules with one be too burdensome? Support your thoughts with scholarly citations and respond to two posts by either politely disagreeing and supporting your argument, or building on the individual's thesis.
