Organizing bookmarks between Desktop and Android I am  trying to manage my bookmarks both on my desktop and on my Android smartphone. My needs are as follows:


I should be able to retrieve my bookmarks wherever I am, for instance on a PC I do not own
there should be an Android client (obviously)
there should be an easy way to add a bookmark from Firefox, for instance a bookmarklet


Do you have any suggestions on how to do this?
Though it's in no way a classical bookmark manager, you could combine a few things:

WikiMind note is an editor with Wiki-Syntax support. So you can embed links and even structures easily (pictures as well)1. It stores all the data files on your SDCard, so they are easily accessible with other tools.

 

This fact (files on SDCard) you can put to use with FolderSync. As the screenshot2 shows, FolderSync supports a lot of cloud services: Box, Dropbox, Google Drive, Ubuntu One... It can also sync with local resources at home (e.g. Samba/Windows shares), or any FTP server, just to name a few examples. This way you can easily use your notes on multiple devices.

For usage on your desktop computer, there would be WikiMind desktop and (even better) ZimWiki.
