It's not supposed to work like this!

Could you provide me with more information please? Do you use any sandbox or other isolate-JavaScript apps? Is it changing after every page reload or after you close your browser?

I would be extremely grateful if you answered these questions, this way, I could fix it and no more users are going to experience this behavior! Thank you!

In the meantime I suggest you try to reinstall the extension.

EDIT: Thanks for your help, I'll try to fix!
