The AddOn is cool! Thank you developer Startpage24! It shows image thumbnails!
Earlier I wrote: "The addon doesn't understand non-Latin latters, writes spaces instead of non-Latin latters in the file names", but there is another problem. When I press "Download NN files" button, there are as many dialogs as there are files, and the file names in these dialogs are not correct: they like '(-). Jpg'.
This happens when the radio button "Determin filenames" is set to "Let firefox determin the filenames".
When the "Determin filenames" radio button is set to "Ask for each file for a filename", the filenames are correct, but there are 100500 dialogs, man?! And can I save all the files to my folder, that was asked only one time for all checked files together? "Ask for one folder name for all files" not working or I don't know how to use it. Nothing happens when I press "Download NN files" button and specify the full path to my folder.
And second problem: selecting many files. Can you add ability to select several files, that folow one to another, at a time, as it is done, for example, in Windows Explorer, when with Shift key it selects a range of file names?
