This was great, but since the update to Firefox 30, it is now of no use to me at all.
It simply will not remember the search term when opening new tabs. It used to remember the term just fine before, but now it might remember it once or twice, but then it completely clears the Find Bar.
And it not only clears it in the new tabs, but also in the original one, eliminating the search term altogether and requiring that it be retyped.
Are you using the latest beta version that I refer to in the add-on description? If you are, please send me an e-mail or open an issue in the support thread about this, as that's obviously a bug and I need more information about it to fix it.
EDIT: I see the bug now, it's not exactly as you described it though. The search term is preserved initially, but it's cleared when you try to use the find bar. I will fix this for the next version of course.
