DO NOT USE versions prior to this review, 2010-05-07 and only after this bug has been fixed by a new release.

I can reproduce a horrifying slowdown bug caused by this extension, and only by this extension.

Steps to reproduce:
1) Disable all addons except this one
2) Visit any extremely large page with mixed text, pictures and images. This issue is most visible the larger the tab's content is.
3) Open a link in a new tab, in the background. For example, middle-click a thumbnail.
4) Try to scroll up and down while the tab is loading in the background.

What is seen is a horribly sticky scroll with delays of over 5 seconds. Presumably a faster computer would reduce this speed limit.

Reproduced on a 2Ghz single-core, with my CPU usage spiking to 100%.

Another addon which accomplishes this same thing is Snap Links Plus:

It has been tested and works without the above issue.

This review is for a previous version of the add-on (2.0.0.17).
