I dislike running third-party scripts in my browser and have disabled these generally.
In particular, much of Stack Exchange's functionality is dependent on scripts hosted at
googleapis.com (although there are several other locations called out to).
- Adding comments.
- Controls (image, code buttons, etc.) missing from message posting form and the preview does not appear.
- Automatic recognition that you are 'not a bot'.
- Notify daily of new answers option.
I find this annoying - I consider it to be a (mild) security/privacy problem.
But, also, it must cause problems with Stack Exchange's proper function. If such an external site is down: much of Stack Exchange's functionality will fail.
Can this be changed?
