http://wm-bot.wmflabs.org/browser/ is loading assets from external web sites:
1. fonts.googleapis.com
2. code.jquery.com
3. camo.githubusercontent.com
These are all [violations of the Terms of Use](https://wikitech.wikimedia.org/wiki/Wikitech:Labs_Terms_of_use#What_information_should_I_provide_to_users.3F) for wmflabs.org (that Wikimedia website is usually called "Labs" or "Toolforge"), since there is no interstitial warning you that your [IP address](https://en.wikipedia.org/wiki/IP_address) is being sent to a third party.
We should probably host these files ourselves, since many other wmflabs projects depend on them. One could download these files from these URLs, place these files somewhere in the code repository and refer to them using a [relative path](https://en.wikipedia.org/wiki/Path_(computing)#Absolute_and_relative_paths), so that these files are not loaded from jquery.com and other websites anymore, but from some Wikimedia server on which this PHP code lives.
Note that we have our own CDN for cloud services purposes at https://tools.wmflabs.org/cdnjs/
