You can export FoxyProxy for Chrome settings this way:
1. Install the Storage Area Explorer extension for Chrome.
2. Open FoxyProxy options:
3. Open Chrome Developer Tools:
4. Select the Storage Explorer Tab in Developer Tools — this is the extension your just installed in step 1.
5. If you are storing settings locally, select the chrome.storage.local tab. Otherwise, if you’re using Google Sync to sync FoxyProxy settings, select the chrome.storage.sync tab. If you’re not sure, select the one that does *not* say “area is empty”
6. Click export->to file
You now has a JSON file with your settings. You can’t import this into FoxyProxy for Firefox; it uses a different format. But all of the data is there, and if you have a lot of it, we might be able to write a converter for you that converts from the JSON format to the Firefox XML format. Write to us at email@example.com
