Ao desinstalar essa extensão o consumo de memória RAM que beirava os 3GB caiu para 700mb, melhor utilizar o lightshot que consome menos RAM e é muito mais eficiente.

Works very well and the features are nice. It does not support to capture extremely long pages though, FF hangs when doing this.

Great screenshot extension. It works smoothly, it's intuitive and well, it accomplishes everything it promises.

Excellent addons, very helpful tool, some issues on sites working with iframes

PERFECT!!! Just what I needed~!
Spent money on SnagiT Screen capture tool and it quit capturing webpages without extension from Firefox or Chrome browsers, but this tool works FAR BETTER!!
Thank You Nimbus~!

On very few occasions it failed to do what I asked it to do, but for the most part it is a beauty. I am able to quickly cut, edit, and copy/paste the image to another browser window directly from the app without needing to save it to my hard disk.
Such a time saver! Full of well thought out features. Can't say enough about it.

Assim como no teste com a ferramenta nativa do Firefox "Capturar tela", esta extensão também não conseguiu tirar uma captura de tela de página inteira, sem ignorar o conteúdo de uma longa "sobreposição" (overlay), que é o conteúdo mais importante da página. Arquivo da captura do Nimbus Screen Capture: https://postimg.cc/5Y7wBpJP ; Site: http://www.arquivoestado.sp.gov.br/site/acervo/memoria_do_imigrante/pesquisa_livros_hospedaria ; Arquivo da captura da extensão Awesome Screenshot Plus: https://postimg.cc/bDQGmT10 ; Esta captura da extensão concorrente também não está elogiável, porque não está perfeitamente contínua, porém, prova que a captura da Nimbus ignorou totalmente a sobreposição, que neste caso possui a informação mais importante. Além disso, a opção para salvar em disco falhou durante o download repetidas vezes. Copiei para a área de transferência e colei no Microsoft Paint para conseguir Salvar. Espero que leiam a minha mensagem e aprimorem o recurso.

The only feature that works for me is capture "Visible part of page." The other 6 options don't work.

Works very well for most screen shot needs. It's also great for screen recording IF you use it on Chrome. I use it on both my PC and Mac.

Really helpful tool. Can be more so: Yellow highlight is too opaque; covers text. Could have a single "underline" tool for emphasis. Nice you can select and edit. For being in a hurry, offering Screenshot URL up-front would be great. PREMIUM seems unnecessarily expensive.

Why not TWO premium options: 1. lesser cost for students/budgeted with better tools, etc., and 2. BUSINESS who needs the space, features, etc for heftier cost where cost isn't a concern.

addon not capable of taking full website, select & drag also not working. addon can only take screenshots of "visible part". so another useless addon. maybe it is firefox, but I actualy do not care, if they cant make it work, they should stop advertising it.

Расширение Nimbus Screen Capture оказалось одним из наиболее удобных среди аналогичных:)

It Does The job, i like it
