Rated 4 out of 5 stars

After updating to Firefox 29 this is using 100% of the CPU when watching localhost for changes in a directory. Please fix this issue on Linux.

EDIT: I got it to cool off by limiting to 100 files per second but it worked well without a limit before.

This review is for a previous version of the add-on (1.20.1-signed.1-signed).

Very handy tool, but now if you make several changes to a file the browser will reload each time. The existing delay option isn't very helpful for me.

I'd be pleased to edit this review to 5 stars if the author made tabs reload only when they became active. It is very easy to do so using this code:

var tabs=require("sdk/tabs");
tabs.on('activate', function(tab){
//reload tab here

[Edit after reply] I understand perfectly. But it wouldn't hurt to have an additional check-box 'delay reloading until active', right? Given the chance and time I'd be glad to send you a patch myself :)

It is desired behaviour. Tabs should reload each time local file changes. Additional checkbox is not needed as it already does so and reloads only the current active tab. If tab is not active it doesn't even check it's files.
