I started using Avira Browser Safety CHrome extension. It has just on/off settings no detail settings. When it is enabled, it blocks Twitter posts on message forums. No way to change settings to allow them, so have to disable it, to see them. What is threat with Twitter posts/why would this extension block them? Known risk to them?
Yeah, I installed Browser Safety and Safe Search on Firefox. 5 minutes later they were gone. Twitter can be used for social good, business and journalism, but the potential for exploitation by cybercriminals and noncompliance with regulatory requirements is real and growing. http://science.opposingviews.com/twitter-security-risks-13111.html
