"bookmarkable-user-auth" issue

Having the same issue when starting Firefox. I think it may have started in Lucid when I enabled Bindwood (syncing bookmarks with Ubuntu One). However, the message gives no understandable clue whether this is the case or not, nor what username or password it expects -- not a perfect design, really...
I have tried to provide it with my local log-in credentials, as well as my UbuntuOne creds, to no avail.

All the best

I think you are correct about the link to UbuntuOne. I eliminated the problem by removing Firefox and Firefox folders, then reinstalling Firefox. I had to use "sudo rm -irv firefox" to confirm the correct files and directories to remove.

whereis firefox
/usr/bin/firefox /etc/firefox /usr/lib/firefox

Solved my problem

This solution not working in Maveric Meerkat (Ubuntu 10.10) :-(

Do you all have Bindwood extension enabled in Firefox and are behind proxy?

I think that might be the cause.
I disabled Bindwood and didn't get the authentication request anymore. But I'm not sure what kind of services bindwood is connected to and what will this imply :/

cheers,

To obtain the username and password for your local couch db (which is where the bookmarks are stored with Bindwood) execute the following command as your normal user account:

awk '/localhost/{split($3, parts, ":"); print "Username: " substr(parts[2],3); print "Password: " substr(parts[3], 0, index(parts[3], "@")-1)}' ~/.local/share/desktop-couch/couchdb.html

Thank you Douglas, I was able to retrieve both username and password using your awk script, helas Firefox keeps asking it at every launch, even although I checked the "Remember password" setting...

I don't know if there are logs of bindwood somewhere, haven't found any.
