It isn't done twice for me.
Wouldn't you think that we would find such a problem before releasing a new version ?

That means that there is something unusual, either in your Firefox or at the page source.

an img SRC="" would cause such symptoms for example.

Please provide a example URL, try it again in the Firefox safemode if you are sure that it's not related to the page source.

Here's an example: http://muskelverket.se/LABB/

No empty img src="" but - I missed the character encoding and that fixed the problem. The W3 validator don't hint that the encoding is missing if you copy and paste the code but will give a hint if you use the link.

The example is without the meta-tag and the logging is straight forward to a file.

The first is request for html
The second is request for mv.css.
Is it wrong?

Comment 4

[Jan]

Actually both the requests are for the html. There is no logging on the requests for .css

If I put in the meta-tag for the character encoding there is only one request. 

I'm not sure if it is a bug - but it is a different behavior from Firefox 2 and IE.

Just noticed, but Bug 454331 has something somewhat similar (Although it may not be).

I suspect that the second GET for http://muskelverket.se/LABB/ is some kind of reread after a fallback when the character encoding is missing. Tricky because copy and paste the code into W3 validator gives a green light.

This is a mass search for bugs which are in the Firefox General component, are
UNCO, have not been changed for 500 days and have an unspecified version. 

Reporter, can you please update to Firefox 3.6.10 or later, create a fresh profile, http://support.mozilla.com/en-US/kb/managing+profiles, and test again. If you still see the issue, please update this bug. If the issue is gone, please set the status to RESOLVED > WORKSFORME.

Comment 8

[Tyler Downer [He/Him]]

No reply from reporter, INCOMPLETE. Please retest with Firefox 3.6.12 or later and a new profile (http://support.mozilla.com/kb/Managing+profiles). If you continue to see this issue with the newest firefox and a new profile, then please comment on this bug.

I think this is duplicate of Bug 61363. Auto-detecting character encoding need reload the page.
