Thanks for the help, thought I got all, the last mentioned file was not in the list. Now I've FF17.0.11 running, but there are a lot of things very wrong. I can't get it into another language (that's something else than spelling, its about language toolbar, help etc). The nl.xpi from version 17.0.11esr is not accepted because its incompatible, the nl.xpi from version 17.0.10esr is accepted, can be installed, can be set to use it, but it doesn't make any difference, its English and it stays English.
I copied all the user files from FF10 to a new directory which is used by FF17, but it seems that this FF won't use that. So how do I get all settings into the new one, including lists with sites, passwords etc.?
The add-on container seems to run forever, had to do a ctrl-alt-del for popup and with the list and the kill option for deactivating the container. So for non English users its not an option, I stay with FF10 latest.
