It's ok but UI is clunky, poorly designed and there's no quickadd/autoadd from pre-webextensions era. At least a button in addon dropdown to quickly add URL to whitelist would be sufficient.

Mode "Use proxy for all urls (ignore patterns)" seems to not working.

Best proxy addon, but font to big in menu.

Advanced configuration, beginners usability. I had try a proxy that was giving me trouble with others proxies as well as with the default from Mozilla and it worked quite well.

Great addon, but "Edit patterns" page is buggy in WE. If I try to add more than one whitelist pattern at time, these patterns get "synchronized" - they always have the same content after saving.

gut

Interface is a bit unfriendly at first, but once set up it works perfectly.
