For Some reasons this wont work on latest version of firefox.. Unable to save the screenshot

Google Chromede de kullanıyorum çok temnunum. tavsiye ederim.

very useful

Usually easy to manipultae and cut out part of pages you want to keep.
Good for Documentation as well.

Doesn't allow a screenshot of an entire web page; over glorified print screen.

L'ancienne version était meilleure mais pas de soucis, cette extension reste une référence. :-)

Works AMAZINGLY WELL! This is the third app which I had downloaded, and is the only one which actually worked!

Fast, efficient, does the job right. Provides a variety of useful functions beyond simple clip and paste/save a web graphic.

Folks, RELAX!!! It's not the developer's fault!!!

Firefox 57 is brand new, and it's likely that the disappearance of the clipboard feature on this add-on is the result of the not-yet-complete WebExtensions API. Other add-ons, take DownThemAll for example, are delayed or missing features because the API doesn't offer all of the functions that the old XUL API had. Mozilla has said that they're working on this stuff!

There's an important rule with free software: If it breaks, you get to keep both pieces!

Patience! :-)

Review: This is a brilliant plug-in. I only discovered it around 6 months ago, and not a day has passed without me using it since. It's everything a good plug-in should be: small, efficient, well designed and completely functional with no unnecessary junk. I'm very pleased that the developer has ported it to WebExtensions! Thank-you!

OK, now, a reward for folks who read this far! There are Lightshot apps for both Windows and Macintosh. It looks identical to the Firefox plugin, it works on the whole desktop not just the browsers, AND IT HAS THE CLIPBOARD FUNCTION!

Где кнопка сохранить буфер?

В версии 52.5 перестало работать!

Почему вы не сделаете две ссылки для старой версии и для новых и бет версий ???

Многие дополнения не работают в новых версиях мазилы.
Я жду когда большинство авторов сделают новые версии.
Почему резать так под корень!
Почему нельзя оставить и старую версию дополнения?

Really good. Makes unprintable pages printable in seconds.

Awesome Add-on! Its perfect!

Agree with recent comments. That is, the loss of some features, after the most recent update, is disappointing. But I will continue to use the add-on.

NOTE THE REASON FOR THE CHANGES ... limitations caused by Firefox's recent update to "Firefox Quantum" v57.0. This update changed the way add-ons/extensions are handled by Firefox. Explanation here: https://support.mozilla.org/en-US/kb/firefox-add-technology-modernizing?as=u&utm_source=inproduct

!!!!!!!!!! HINT BELOW __________Why did you change something what was good? I don't follow... it appears on a different tab, you cannot write down the file wherever you like - what the hell... ? Why ?
HEY PEOPLE - there's solution !!! GO BACK to previous add-on with > Version 5.1.1 - it still works! :)
