Hi, I just want to say thank you for this extension :kiss: I'm part of a group of people who for the last three years have been building a privacy, anti-tracking, anti-fingerprinting etc user.js for Firefox (obviously there is more outside the browser level that can be done, but that is the project's scope).

For a while it has really bothered me that Firefox no longer fully clears the cache edit, FF does clear the cache, the test site was a little flawed - end edit.. It used to be that you could go Ctrl-Shift-Del and clear Cache and it would eliminate any ETags - you will find lots of older forum discussions and articles where this was proposed. The other way was to disable both disk and memory cache. I have always had disk cache off, but left RAM being used. This still retained the ETag (edit, the test site was flawed: but removing etags allows caching and no etag tracking but may make you a very small subset of users that do this re fingerprinting).

Thanks to your extension and this rule, everything is as peachy as we can get it :+1: There is still a risk of Last-Modified being used as a tracking mechanism for now.

The above link contains test sites for those interested

Thank you. Maybe you should notice that Chrome and Firefox is different when you try to modify a header to blank. Firefox will remove it, but Chrome will keep it and set it to blank. If you have any questions, it's welcome to submit

I hope you get an uptick in users and more help with translations & testing
