Diigo Firefox extension problem with Firefox Portable
Every single extension I installed so far worked flawlessly with Firefox Portable, but now there is one extension that does not.
It is the Diigo Firefox toolbar extension and it works *almost* as it is supposed to. There is just one drop-down list in a pop-up window that just doesn't show when I click on the little downward arrow to the left of the entry field. Clicking there does nothing, nothing happens. However, in the non-portable version of Firefox the drop-down list does show (same version number for portable and non-portable version of Firefox).
So, I now wonder what this could be due to?
