Confirmed, ^ thanks for the post.

After my last post ^^ after I’d updated to .1489 I realise now I hadn’t restarted Firefox. In fact I went straight from updating Avast and updated Firefox from v.20.1 to the current version. Long story cut short: I shut the laptop down without restarting Firefox and trying, yet again, to move the WebRep icon to where I want it.

This morning I boot everything up and the Avast WebRep icon now remains where I put it. Yay!

I’m assuming it was the Avast update that did the trick but as I updated Firefox as well I can’t be sure. Whatever the case the WebRep icon toolbar customisation problem is no longer an issue with the latest version of Firefox.

Whoever sorted it out - thanks.
