FireFox focus switch workaround
For the last few versions of FireFox, I've had this irritating problem.
I usually run with two separate windows open, say Facebook in the background and whatever I'm reading, such as a newspaper, weather website or whatever in the foreground.
Wile loading pages in the active pane, the browser would keep switching to the Facebook (background pane).
Sites with advertising, (this one, various newspapers, broadcast media etc.) would do this all the time.
If a page without multimedia content was loaded, nothing would switch panes (or toggle focus).
I then started looking at the add-ons in FireFox. Noticed that Adobe Flash was set to "Always Activate". Everything else set to "Ask to Activate"
Switched Adobe Flash to "Ask to Activate" and problem instantly solved.
But when you go to sites with content that uses Adobe Flash, you see a box with an icon and below it has "Activate Adobe Flash".
So Flash was causing the focus switch.
Not sure if this has been noted on the FireFox site or is a bug in Flash...
Also, I don't know if this just under Windows or is a cross platform problem...
