Naturally I spot what may or may not be a problem when away from home for a few days and using somebody else's PC which is running FF20 Without being able to investigate further for several days I can't work out if this is a FF issue, if my site has been hacked or an effect of running Adsense.
Looking at a page on one of my sites we had a message "Firefox prevented this page from automatically redirecting to another page". Naturally as it wasn't my PC I wouldn't risk clicking OK and FF gives no information about the potential redirect. Viewing page source shows nothing in the header that would force a redirect. I am aware that this message is an option that can be switched off but again I don't want to play around with the settings on a borrowed PC.
Exploring my site I discovered that this only appeared on pages with Adsense.
Does anybody have experience of this being a spurious message or should I be speaking to my host about security?
edit After submitting this post the same message came up on return to webmaster world. /edit
I get this every time I submit a posting on WebmasterWorld. I fiddled around with settings but short of unticking the checkbox I failed. I just click Accept for WebmasterWorld when I post. This has been happening for a year or so now, not just FF 20.
Not hard, takes just a few minutes to figure it out by process of elimination.
Firefox/Firefox > Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page"
The setting in "Firefox > Preferences > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.

Further note: This feature in FF-- it goes back a couple of versions-- only applies to redirects that happen on the page itself. It doesn't apply to server-side redirects, as when you ask for example.com/index.php and get sent to www.example.com/
Although it's intended as an accessibility feature, there's nothing to prevent you from using it as a security feature ;)

I was hoping to find an Exceptions list-- same as for cookies, popups and so on-- but it seems to be hiding.
