Tab title doesn't auto-refresh with data in the page
When I am on a certain site, some data in the page are repeated in the title of the tab, and these data are always changing (once per second). These are financial data.
On my work PC with a portable firefox, the tab title is well auto-refreshed, as the data in the page is. But on my home PC, with a classical firefox and a portable version, titles don't update, and the data in the page don't auto-refresh either.
EG : what I want (and have on my work PC) : when there is a 6 in the page, the tab title is 6. One second later, the page shows a 10, the tab title is also a 10. Etc, etc. What I have (on my home PC) : when there is a 6 in the page, the tab title is 6 (the first loading of the page). One second later, nothing has changed. I have to refresh (or reload) the page to have all data in the page updated, and so the tab title.
This is the same firefox configuration from my home PC and my work PC. Even if I disable my extentions, it stays the same: update on my work PC, and nothing on my home PC.
Does anyone have an idea how to fix that problem ? Thanks a lot !
