I installed Tidy Favorites Converter and tried to import my bookmarks, but unseccesfully.
1. Import for Firefox doesn't work at all - it refuses it.
2. Import for Google Chrome (about 1000 bookmarks) should take 67 hours and occpy more then 1 Gb space
3. I tried to import only 3 bookmarks from IE, it wrote it will take about minute and 1 Mb, I imported, but nothing appears in my account.
4. Add bookmarks button works
