priority not working anymore

this crap is totally unusable

Sorry this addon does not work either. And its UI is cumbersome, why do I have go to addon settings to set UA? Cant this be done in a popup?

Can't configure multible hosts/domains. I add the first rule, everything ist still fine. After i add the second rule and i left the focus from inputfield, now its seems like shuffling all data. In rule1 and rule2 are the same host/domain and/or all the Useragents are the same right now. Whats going wrong?

The "Add" button doesn't work, cannot add rules.
