This is, excuse me, a damn fine extension. I've used I can't tell you how many extensions in my life and this is one of the best.
helpful tool, thank you
很好用，用上后那些打不开的站点全部可以完美的打开
looks like a really helpful tool. at one point it broke access to my site though and pages would not load
I found this extension very useful, but it stopped working. It was working month or two ago, but now it is not generating policies at all
$7 per month .. should be stated upfront.. looks handy tool but dont like being tricked into having to pay for simple 1 time report.
It was surprisingly easy to generate a content security policy with this tool with my limited csp knowledge. Thanks for creating this extension!
Super helpful extension! Finding edge cases in CSP is definitely annoying, but this saved me a lot of time. I think there were some edge cases with blobs that weren't covered, but great product nonetheless.
Made it really easy to add a CSP to the site I'm building. I had to make sure I hit every possible interaction, but this cut down the iteration time for finding violations so much I'm not sure I can even estimate it. I'm sure I'll still find some violations from oddball browser combinations, but sending the reports to csper.io makes it easy to track and add those as they come in.
