You may get lucky as this forum will possibly be read by more users than the bugzilla.

It is probably an idea to ask on one of the Mozillazine forums e.g. http://forums.mozillazine.org/viewforum.php?f=9

Good luck.

Nope i haven't got a single response since i found the fault nightly and posted it in my bug report. Seems hopeless.. This is times when i even feel IE 9 is a better browser or at least the devs behind it.

Looking I do see you have a bug that has had some attention. Possibly it is a situation tending to affect only a small number of sites, and possibly mainly using none English characters.

Not really something I can help with. One thought is, do you see a similar or the same problem on any other public Swedish sites, if you do that may be a bug you could file with more likelihood of it receiving prompt attention.

It is better to get the SourceStamp of the Firefox versions.
That allows to see the checkins.

See about:buildconfig on the Help > Troubleshooting Information page or the file application.ini in the Firefox program folder (C:\Program Files\Mozilla Firefox\)

SourceStamp=c5f35032f22d

It happens just on this particular site i listed in my bugzilla post. Every other Swedish site works just fine. Problem i can't see why this particular problem doesn't occur in other browsers like IE, Opera or Chrome or even the old Firefox 3.6xx but does only show up in stable FF 4.0 and up.

I see this bug about cookies during that period (Jul 29 to Jul 30 2010), but have no idea if that is the cause.

You also need the sourcestamp of the Minefield/4.0b3pre 20100729073046 build.

The one it worked for is SourceStamp=b26489e73818

Could this be it?

Seems it was Linux.

Im sorry but i don't have the expertise in this area to exactly locate the change any dev did in that particular time. I'm just a normal user. I did as much as i could until this point. Now only any dev could notice it and add it to his/her task to find out the source of the problem.

Thanks!
