Simple, but do the job ;)
The user interface is clean. You can set a refresh every each second if you want. Some extensions limit the refresh time at 5 or 10 seconds. So, when I can't use my favorite extension Live Reload (by Blaise Kal) that refresh the page only if a linked file is modified, I use this one. Thx

Супер. Мне нравится.

Leider funktioniert dieses Addon nicht zuverlässig

Very poor - Have persevered with this add-on for a couple of weeks now. I find I have to constantly re set the app to work. Usually I will have to re set several times over an hour period. No more - Looking for a more reliable Auto Refresh add on.

This is a pretty good add-on. If it allowed to edit the list of URLs as plain text, and to use basic regular expressions (for example, to set a refresh over a whole subdomain or subdirectory), I would give 5 starts without a doubt. It is specially useful combined with Instagram Web.

Nice, this can pass the warning.

Works great! Try it out...

Please make hotkeys “Stop” and “Start with last value”.
It`s very important for this add-on.
Please, please, please ))
