Upon evaluating this tool, I have identified the following pros and cons:

Pros:
- The tool is free of charge.
- It is user-friendly.

Is it up to par with my standards? Yes, it meets my requirements.

Cons:
- The inability to customize or change the extension icon led to a 4 out of 5 star rating.

In conclusion, I recommend this tool to individuals seeking a satisfactory solution.

Paywalled extension, leaves watermark which makes your picture unusable. Asks for donations.

Easy to use and powerful

They brag about "no crazy permissions" but to add to Firefox I need to give it "Access your data for all websites"!!! Also there is a warning, "This is not monitored for security through Mozilla's Recommended Extensions program. Make sure you trust it before installing." ... this is not acceptable

Work properly. Easy to use.

I love the simple use. I use it all the time. Love it. Thanks for creating this.

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. Importante ressaltar que a sobreposição foi parcialmente capturada e aparece repetida diversas vezes até o final da página. Arquivo da captura do Explain and Send Screenshots: https://postimg.cc/H8y0mppC ; 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 do Explain and Send Screenshots ignorou totalmente a sobreposição (exceto na primeira página). Espero que leiam a minha mensagem e aprimorem o recurso.

Five stars for Waterfox Classic-compatible version 9.1.1.7

Does NOTHING! Forwards 2 blank page with half circle on it. Also doesn't display ANYTHING if U use a dark theme or have background images disabled, & can tell from how it jerks page around that it's not really a full page snap but multiple ones separated = LAAAME! =P Thanx so much 4 WA$TING my time! =)

Note: Went 2 my old stash of addons I saved & 'Abduction!' works much better than N E of the 'latest greatest' stuff on the Firefox site. Of coruse, in their 'infinite wisdom' they delete the stuff that actually works, I guess because their goal is 2 keep BREAKING the browser so they can sell 'Cu$tomer $upport' contracts or something = lame. Reminds me how 'Mouse Gestures Redox' is by far the best gesture addon, & like the rest if U tweak Firefox to IGNORE the 'compatability' lockouts it installs & works just fine = WAY better than the others! =)

why does this addon require Web access permissions on firefox only when it only needs notifications permission on chrome.

Adoro essa extensão! Salva minha vida quando eu preciso bater uma screenshot da tela. Completo, rápido, simples e eficiente!

Хорошее дополнение, но у меня так и не заработало сохранение всей страницы (с перемоткой). Правда у меня 2 монитора.

烂透了。根本不能用。

αρκετά χρήσιμη

After I fix my problem with blank popup the extension works good.

(+) It do screenshots, allows to edit them and upload. No need to press printscreen key, open Paint etc - all features in one browser.

Thanks for developing, very easy and useful! Killer feature is that it give direct link to image instead of webpage with tons of banners :)
Will be good to see pixel counter (with&height) when I capture area or cropping image, and ability to move borders via mouse after first selecting for precise cropping.
Also will be good to have ability for screenshot full screen (if this possible), not only browser page.
