In Firefox, there’s a little circular thingie in the upper right-hand corner, in the menu bar. It spins around when a webpage is loading.
If you click that little circular thingie, it will stop what it’s doing and take you to the Firefox home page.
It will do this even if the page was in the process of re-publishing your entire blog to your webserver. Even if you didn’t want it to do that. Even if it was a complete accident, and you now have to re-re-publish it.
So don’t click that little circular thingie. Like I just did.
