Alert message opening multiple times on autorefreshed pages

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a page (HTTP) that autorefreshes by reloading, and with HTTPS available 
but not included or enabled in HTTPS-Everywhere.
2. Let it autorefresh/reload 2 or more times.
3. See HTTPS-Finder alert message has opened as many times as the page 
refreshed/reloaded.

What is the expected output?
To only show 1 alert message.

What version of the product are you using? On what operating system?
0.72d3 with FF 7.0a1 (2011-07-04) x86 on Windows 7 x64

Sorry, I missed one importan point in the description... this only happens if 
you focus on another tab while the alert is showing, otherwise the alert 
timeout hides it. If you change focus, when you come back to the tab with the 
autorefreshing page, you`ll find as many alerts as many times the page have 
refreshed.
For example, that happenned to me here:

I haven't had time to test this, but it sounds similar to another bug that was 
in a previous FF nightly (rather than the extension). Have you tried/are you 
able to reproduce in FF5? 

Also, when you say "refreshed/reloaded" more than once, do you mean when you 
click on other links within the page? (I see that site has links pointing back 
to http://eleconomista, even when on the https:// site). Otherwise HTTPS Finder 
should only switch you from HTTP -> HTTPS once per http page.

Thanks

Now I've tried in FF5 with the same results.
3 more details:
- this happens when Automatically Enforce HTTPS When Available is unselected, 
it happens for the Go to HTTPS alert
- it happens when I change focus to another tab while the alert is showing, not 
to another window
- it happens overlapping the alert messages one on top of the previous one as 
many times as the page autorefreshes

When I say refreshed/reloaded I meant that the page autorefreshed reloading the 
whole page, not just a part of it, I'm not referring to the page links. And it 
happened to me on other autorefreshing pages not just the one in the expample, 
but this one have a pretty short timeout.

In the previous comment, when I say it happens after changing focus to another 
tab, I meant, after that I can change to another window while keeping the same 
effect, but to start it, I had to change focus to another tab in the same 
window first.
