FF 91: add-on stopped working a few version back. Should be mentioned at top of page, or removed.

It does not work in FF version 84.0.2 and hasn't worked for a while.

I also confirm AddSearch no longer work as of Firefox version 78.6.1esr (64-bit)

I also confirm AddSearch no longer work as of Firefox version 83. I love this add-on, I hope Burning Moth updates it soon.

Was a fantastic add-on, unfortunately doesn't work with latest firefox (83.0)

It's not working.

This works most of the time, but lately this error appears and prevents saving the new search:

Firefox could not download the search plugin from:

THANKS！

This extension seems to now be totally non-functional (August, 2021).
A real shame, because it was great being able to add website searches that don't come as standard in Firefox's search bar.

It doesn't work on Oxford Dictionaries websites:-(

COOL!

I have searched a successor to "Add to Search Bar" add-on for a long time., which does not work for recent Firefox.
I found this is "the successor"!

As commented by someone, for some sites, this add-on does not seem to work.
But, it is the fault of the recent specification of Firefox, I guess.

I deeply thank the developer.

Does not work. Download Error Code fills the entire comp. screen. Should be suspended until repaired.

Gives a long error when adding search (Google.com, Steam Store.. etc.) now:

The error is way too long. Some places like Dictionary.com don't give error but don't work despite being added to search bar.

new add to search

В Firefox 64.0b6 x64 под Windows 10 на каких-то сайтах работает, в вариантах быстрого поиска появляется новая кнопка, работающая так, как задумано. Что-то - нет, выдающее сообщение вида "Firefox не смог загрузить поисковый плагин с http://api.burningmoth.com/1/OpenSearchDescription.xml?method=get&action=https%3A%2F%2Fpetrovich.ru (...)".
