very useful addon Rated 4 out of 5 stars
A configuration item might be useful:
ReloadEvery hooks itself into the "Reload" button, and adds a pulldown. There are cases when this is not desirable, for example in combination with the Stop-or-Reload addon: on every page load (not only reloads by ReloadEvery) will the icon narrow. When load has been completed, the now wider "Reload" icon is displayed again, resulting in a very nervous toolbar by wiggling all buttons right of the "Reload" button.
An option to disable adding the pull down to the Reload toolbar button may be of help here.
