Fixed a lot of stuff and now CAGE starts on Firefox without (to much) errors. Not all tools work as they should right now but that is just what I expected as some stuff uses Chrome specific stuff. Give it a try and download it from Github and give me some feedback how bad/well it runs for you.
[UPDATE] I just uploaded CAGE to the Firefox Add-on page. So you can install it from there and receive updates via auto update.
As CAGE reached beta I renewed the bugs and wishlist page. Anything added there will be added to the github page and the comment will be deleted. That way it is easier for me to keep track of that stuff.
Finding and removing bugs is now my #1 priority, so no new features for some time. I will rework some stuff for sure (like moving all settings to the settings) but that's all.
Links to the bugs and the wishlist are added to link list on the right side.
