TLDR Namecoin should facilitate a free internet first in those geographical areas where the freedom is overtly lacking.
Namecoin enables already uncensorable domain names accessible all over the world. But a DNS is not responsible or intended for distributing the content of a website. If ZeroNet, a decentralized open source project, is not enough for you, then provide your content on
Steem, a decentralized blockchain for distributing such content. If this should be censored one day or you don't trust in it operate your own webserver, you can take a ten years old laptop for it. There are enough possibilities to communicate or to provide content. To be free from any DNS just type in the IP of your desired webserver and in most of the cases you'll get the content.
Here is an experience I had not too long ago. Explain how Namecoin would solve it.
I was in a country which is considered a large democracy. For whatever reason, I visited the website of American Spirit tobacco. I wasnt able to get decent tobacco in that area and was trying to look for a solution.
When I typed in the domain I got a message along the lines of This website blocked for security reasons, security incident xyz logged from ip 123 etc.
Name resolution doesnt seem to be the issue there. That government has far less interference in the internet than some other countries. For every carefully crafted well developed solution which people like you develop, bureaucrats only have to press a few buttons and the solution is cancelled.
If Namecoin resolved a .bit domain to xyz ip a government only has to watch traffic to that ip and restrict it. If there is extra software used to get around restrictions then a person is being put in the position of being criminalized by the local government for using counter government software.

That said, Im not entirely clear on what your plug in does. Is it going to allow anybody using the associated browser to equally click .bit or .com?
If that is the case then it might be a pretty big deal. Brave browser, for example might see an appeal in it.
