- by Firefox user 15822544, 2 years agoRated 4 out of 5This satisfies my immediate need - bypassing flaky DNS on my intranet VPN - pretty well! Enter hostname, enter IP, click "Add", click "Save".
There is still some room for improvement. Like many other reviewers I initially got tripped up by the form's habit of clearing itself, meaning that one field must be manually typed. And by the Save button, which must be clicked quite promptly or the data will disappear again. Both of these can be addressed with practice, though.
My one other issue is its URL rewriting rule - it looks fairly nice as e.g. "http://127.0.0.1/www.example.com/", but Firefox can't understand that entry format, so if you edit the URL at all (or even just hit enter on it) Firefox will no longer know what you mean and it will garble the URL.
That said, this extension is already quite helpful and it shows good potential too!
