I definitely have no problem paying for a good browser app, if it helps me:
1. do my work faster
2. give me a competitive advantage in my business
3. provide a higher level of service to my few clients
I'm not sure I would specifically pay for an extension to analyze social data. I'd have to see the end results first, and evaluate it based on that.
In terms of pricing, don't limit yourself at the $1 to $3 app level. Evaluate the pricing based on the value provided to the customer. If it helps your customer earn $10,000 more over the course of a year, there's nothing wrong with charging $100 for it, or more.
For the customers not bothered by the transaction cost - there's not much different between $1 and $30 or more.
