Tab / the index tab goes on showing that rotating symbol?

[Dirki]

Often the tab / the index tab goes on showing that rotating symbol / blue dot (instead of stopping showing it and then show the name of the web page or something else). Why is that? What does that mean?



There are some websites / web pages which, when accessing / opening them, use performance of one's own computer. E.g. of the CPU. Does that have anything to do with it?

Respectively, is there an Add On or such that shows if a website / web page uses one's computer performance?

I guess those images mean you are having trouble connecting to the server or loading the page.

I think the blue dot is the tab-loading.png image.

Yes yes, but the page appears to be (completely) loaded, like usual.

I think the blue dot is the tab-loading.png image.

Yes, I would say that too, but why is it shown all the time sometimes, although the pages looks loaded?

Thank you for the links.

The following page loads an offsite google analytics script. That script doesn't change how the page appears. If the google-analytics.com server times out, then maybe you would see the blue dot.

You can use the network monitor to show all the http requests.
