Musts to be useful Rated 1 out of 5 stars

It's a must to do to things, on let us save the files, and to use the custom user agent that is being used in requests. I am using "User Agent Switcher" to let me do dev work on a live site without others seeing it.

Also it seems to never crawl all the links, so it's not working right or helpful.

Also, it doesn't seem to work if you log in as a user so that it will pick up hidden pages so it's not using the sessions of the browser as is? This is important to ecom sites with carts and user areas. my stats fed back was that there was 4000 unused rules, 4 pages crawled yet 183pages were ignored when they would have helped reduce the unused rules.

With not being able to down load a css file of the used rules or even picking up the other pages, this is not useful at all...ATM this is just a things to do but no value to it at all.I hope it's fixed to be useful soon cause it's a great idea and i had high hopes for it.

This review is for a previous version of the add-on (3.01.1-signed.1-signed). 

Firstly, the extension does not crawl sites like a search-engine robot, it only follows links from the first page you crawl, so any pages that are not linked from that, will not be tested. You need to get it to crawl a sitemap (HTML or XML).

Secondly, it does test pages as the same user (ie. as you), so it will pick up login items, but note that the spider's default behavior is to disable JS on the pages it tests, so it doesn't pick up dynamic content. You can change that in the "Spidering" tab in Preferences.

I'm not sure what you're referring to by custom user agents -- it won't make any difference to the extension what UA you have. Or is that what you're saying, that it should?
