Broken and Discontinued Ohodnoceno 1 z 5 hvězdiček
My apologies to the developer, I was not able to find any way to contact you about this. However, since you mention in the description you've ceased work in the add-on, I don't think this review is overstepping in any way.
Obviously, from the developer's own words in the description, this add-on is no longer maintained. And as other have already mentioned, it will break completely in future versions of Firefox.
I have written my own add-on, called "FindBar Tweak", which has similar timeout and hiding features. Although these features are not exactly the same, they work as a great substitute which ensures compatibility with future versions of Firefox. I would invite everyone to switch to FBT instead of this add-on.
I'm sorry for the spam, but I believe my add-on now becomes a necessary alternative to Hide Find Bar, which will stop working completely in the very near future.
