This AddON worked perfect till yesterday (Firefox 45.0). Then the Myibidder button in eBay disappeared. I couldn't get it back, neither by deactivate/reactivate nor by deinstall/reinstall. Too sad. Please fix the problem as fast as you can. Thank you in advance.
Update 1: It still works properly with Chromium/Chrome.
Update 2: I'm successfully using all the AdONS for more than 24 months and without any conflict between them. Well, let's have a look.
