The "Access your data for all websites" permission

[XxX-Force]

I apologize for opening this issue, but posting at your site will not complete for me, and I don't see anywhere else to ask. This is what I was trying to post:

Hi.
Does this extension send any data (besides the user agent) to anywhere?
"Access your data for all websites" is a little concerning. Why is such a broad permission needed to transmit a UA string?
I'm not being accusatory or implying anything, so please don't take any offense. As I said, simply concerned, and would really appreciate it if you could explain this for me.
Thank you.

Again, apologies for cluttering up the Issues here, but I really would appreciate some insight. I've been burned by extensions in the past, and I admit I'm too ignorant to evaluate the code, or discern the reason for the permission.

I am curious about the same thing.
The Firefox user agent can be manually switched from Firefox configuration by accessing about:config configuration page. I do not know much about web browser add-ons but I find it a little bit weird that an extension that changes the user agent needs permission to access all data for all the websites.

Starting to wonder if this project has been abandoned. Does anyone have a suggestion for a safe alternative, please?
