XF 2.2 htacess require_user backup-dir

[Robert9]

For many years I have done something like this:

/backup/
with software to make backups

/backup/.htaccess
/backup/.htpasswd

and in /.htaccess

RewriteRule ^(backup/|data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]



Some time ago this stops working.
First I thought it is a problem of the backup-software, but now I have done everything by hand and the problem is the same.
Is there any change with xenforo?
Is there any change with apache/.htaccess?

WOW!
Again it is a problem of Firefox. Using Chrome now and everything is nice like it should be.
