Issue with Firefox 29 and addons bar. Bewertet mit 4 von 5 Sternen

At first, thanks for this useful extension.

Same problem for me as below: the default "addons bar" destination for Gmail-Manager icon don't work with FF29 anymore.
If I use an extension that restores the addons bar, gmail manager icon loose its placement at restart (the icon is moved at the extreme right of the navigation bar after a restart).
Please fix it (it should not be so difficult, maybe changing the default placement for the icon will solve the problem).

Thanks for the tip. It is a good temporary solution, but if I've to prepare a firefox profile for an unesperienced person, it will be not able to use this trick after he creates his account.
