This app asks for a full acces to all your web datas (including saved logins and passwords !) why ? I don't think an app needs such a a critical acces to remove some cache (another authorisation exists for that in firefox).
That makes me very suspicious, and I didn't install this add-on.

Great idea, works fantastic. Would be very nice if this would work together with Livereload (https://addons.mozilla.org/de/firefox/addon/livereload-web-extension)

This is exactly what I need. I use it very often and it works perfectly.

Just one niggle: it would be nice if it used Firefox’s new “Manage Extension Shortcuts” API so that I can customize the keyboard shortcut.

Simple and effective

Indispensable for web development.

This is the best CSS reloader addon, also compatible with WebExtensions.

I don't have to reload the whole page to see my CSS changes, just press F9 and that's it!

This is a tool that does one thing and does it well. I sometimes forget it isn't built-in and find myself hitting F9 in a coworker's PC.
