First - Thank you for the help.
I have checked and no remaining mountings from the first attempt. I have used umount to undo what I have done year ago.
The reason I was asking for Firefox with flash is because I would like to install on it my personal bank certificates and to deal with my account. On first tought I decided the site is flash based, but maybe I am wrong.
Why I need this - because I have installed the certificates on Maemo. MicroB is able to start secured https. But once I need to make bank transfer and it has to be signed it should appear smaller window to ask me to enter the pass of the certificate. But the appearing window is partially seen and I am unable to do the operation. Therefore I am looking for alternative way to deal with this.
In any case I will try with ED to see if it will do the job. Just to ask if Iseweasel has the same ability as Firefox. I mean to put master password and to install certificates in it.
And why there is images with notes as "Browser with working flash ...etc". Seems I am asking quastions with unclear meaning. I was asking for such a image.
Now ... I have placed the ed-squeeze-final.ext3 in folder /home/user/MyDocs/tmp
I have created the following folder /mnt/debian to use it and to mount on it the 4G partition mmcblk0p4
The folder /media/ed is created to mount the image.
Then the sequence should be:
mount -o loop /home/user/MyDocs/tmp/ed-squeeze-final.ext3 /media/ed
mount /dev/mmcblk0p4 /mnt/debian
cp -a /media/ed/* /mnt/debian/

After that I have to edit .chroot directing to /dev/mmcblk0p4
Am I on the right way?

P.S. After some reading here http://talk.maemo.org/showpost.php?p...postcount=2821 I have decided to use debian-wheezy-sulu-Sci.img.ext2 image. Then I just need to change the names of the above written command lines and that is all.
Please, take a look to the 3 lines and if they are correct I will execute them to implement ED.
