Works perfectly and does not require any special permission.

The plugin does what it's supposed to do and it does so quickly. But most of the time, it's simply not working. I found that it's working the first few times after I open Firefox. But then it stops working. I can't get the CSS to reload. I try with hotkey, context menu and the {} icon in the address bar.

Closing and reopening the browser is even more time consuming that reloading the page and all of its assets.

Important EDIT:

I realized that the plugin stops working when I'm using "responsive design mode" in Firefox's developer tools. As soon as I exit that mode, the plugin starts working again. So it's not random.

MORE IMPORTANT EDIT:

The developer of this extension fixed the issue and now it's working perfectly, even when I'm using the responsive design mode. Great add-on! Great support!

Replaces the old CSS reloading plugin I was using, since that one no longer supports the latest version of Firefox. The other review here is outdated -- there is now an icon in the address bar that lets you refresh the page with a click.

Dear CSS Reload add-on authors (and I mean authors of ALL add-ons of this type)!

You must, YOU ABSOLUTELY POSITIVELY MUST provide a non-keyboard UI to trigger CSS reloading. Having ONLY a keyboard shortcut will make your add-on UNUSABLE to those whose desktop environment intercepts this shortcut for something else!
