Rated 3 out of 5 stars

Really useful. I don't understand why this add-on is so big.

This review is for a previous version of the add-on (1.5.6). 

Glad you like it. Things that add to its size: implementing its various options, fixing issues that occur as a side-effect of leaving the menu open, supporting both Firefox 3 and Firefox 4, translations by Babelzilla, the per-file MPL text. The code also includes a lot of comments (documentation) facilitating my ability to update it. It *is* open source; feel free to see for yourself which features take up the most code. It could be made somewhat smaller, but approx. 22kb (Firefox 4 no longer uncompresses them on disk) is not really that big, and taking time to find ways to reduce its size is not a high priority.
