It seems that you haven't installed the Browser Extension on this computer yet. In order to place notes on pages outside of mystickies you will need an extension or the bookmarklet below.
If you're not quite sure how to use mystickies, see Getting Started to answer some basic questions about what MyStickies is.
Currently we have an extension for the Firefox web browser and extensions for Safari and Internet Explorer are in the works. However, if a plug-in is not for you, or your browser is not currently supported, you can use a bookmarklet to use MyStickies. The downside to the bookmarklet is that you will need to click the link in your bookmarks/favorites on every page you would like to use or see your Sticky notes. Simply right-click on this MyStickies "jac" link and select the "Bookmark this Link..." or "Add to Favorites..." menu option to add the bookmark to your bookmarks menu. Now, whenever you need to place a note on a page or see notes you've already placed, choose the bookmark from your menu.
Mystickies would love to hear from you if you have any issues or think of any cool features that would make MyStickies better. Please don't hesitate to let us know either through the feedback button in your browser extension or by sending us an email at [email protected]
Hint : Press Alt and click+drag to easily create a note on a web page
