Seems to work Rated 5 out of 5 stars
I installed this on a fresh install of FF 12.0, which was installed to a fresh install of Win7.
When I select text in the upper right search-textbox, the selected text is copied to the clipboard...which is incredibly counterproductive. This does NOT happen if I simply click on the textbox and FF auto selects its contents. It DOES occur when I use the cursor to manually select the text in the upper right search-textbox.
Another person posted about this, and the developer said he could not reproduce the problem. Hopefully, this explains the problem.................
The problem with the search bar has been fixed in 1.0.
