Interclue for Firefox kind of excites me because I think they are trying to do a good job with a browsing idea that really hasn’t been my cup of tea yet, the “thumbnail preview”. One positive is that they say it stays out of your way when you do not need it – which is my argument against other extensions like this. As you can see in the preview, they offer more than just your standard screenshot of the next page too.
Here is how the developers of the extension describe it:
Interclue displays useful information and relevant next actions for almost any link on the web. Clueview tooltips are not like other previews, they show you only the most relevant content straight from the page, rather than relying on small cached snapshots or large scrolling windows.
This could either be a really helpful tool or an annoying clutter feature that drives me batty after 3 minutes of use. I think different people may take different things away from it. if you enjoy the idea of having a sort of “picture in picture” preview with some other handy links give Interclue for Firefox a shot.
