Funciona perfeitamente... ❤️

It works great so I have updated my review to 5 stars.
I am just leaving below the process I had to go through to install it, in case it helps someone else. I do not have any issues with the app or the developer. I just found the Firefox or is it the Mozilla process difficult.

*****

The desktop add to collection worked, but had to use my browser's search to find the extension.

if it's as good as everyone finds it i'll be able to up my review to 5 stars.

help, i have tried loading it for 2 hours now.

setup nightly plus debug mode
setup my own collection so i could have other extensions.
(if i do not have my own collection i can add recommended as usual but nightly inactivates them if i setup or use a collection)

tried the desktop route but ext not listed

tried the paste full address in android route
but add to firefox button won't light

tried download but told ext not supported.

sorry need some help.

pdf so useful cannot understand why not included in firefox

I absolutely love this. It is so much more practical than native PDF apps. I can open PDFs to read later and not lose them. I can open more than one PDF at once. Fixes my single biggest annoyance with mobile web browsers (Chrome and Firefox)!

Outra extensão muito boa para se utilizar no Firefox para Android. Manuel, esta incrível maravilha tem de ficar na lista de extensões recomendadas no Android, além de ter como base o pdf.js da própria Mozilla já é meio caminho dado. Tomara que adicionem á lista, porque é uma extensão que ajuda muito mesmo. Continue com este empenho, pois sem o 'Android pdf.js' e até o 'Save Screenshot' não sei o que seria deste navegador, agradeço sua contribuição para uso deste navegador.
PS: Pena que não se pode utilizar no modo anônimo, mas é assim que funciona, existe prós e contras.
Até mais e tudo de bom para você 🙋🏻‍♂️.

super!! :-)

Brilliant! Mozilla needs to make this available in regular Firefox recommended extensions.

This greatly simplies the process of opening pdfs in Firefox Mobile. They now can be viewed directly in a new tab instead of requiring it be downloaded first.
