I keep getting the following message every time I try to open different sections of SF:

This website wants to run the following add-on: 'SVGControl Module 2.0' from 'Adobe Systems Incorporated (unverified publisher)'. If you trust the website and the add-on and want to allow it to run, click here....

This has only started this morning, when I opened a new browser. I've tried rebooting, and I'm still getting the message.

Is anyone else getting this? Has there been some work done on SF overnight that could have caused this?

If the answer to both the above is no, I'll do a restore.

I need to know this is safe before I say yes to it.

SVG stands for Scalable Vector Graphics. It's a type of image format which is reasonably new. I'm surprised it's coming up on SF, but you are safe to allow the use of the Adobe plugin, it's the only way of viewing such files in Internet Explorer. Firefox support is built in.

cheers !
