My Reviews

OurStickys - Sticky Notes on every page

Rated 5 out of 5 stars

I have used this Add-on for organizing and filtering literature in several tabs while writing a thesis.
It was a great help and worked exactly the way I wished such an Add-on would do :).
I didn't use or require the sync future so I can't tell anything about that specific functionality.

Reply To All Reminder

Rated 5 out of 5 stars

Does exactly what it's meant for :). Great Add-on, thanks!

Tab Groups

Rated 5 out of 5 stars

It was a great work you did here after tab groups were removed from Firefox core and until the removal of the old Add-on APIs had been decided. Thank you :).

Excellent first impression!

Private Tab

Rated 5 out of 5 stars

Small, simple, no restart required and it does what it should. Very good :).

Only one thing: It doesn't work with e10s until now. I can't open links in a new tab or in a new private tab if this add-on is enabled.

FavIcon Reloader up to FF 48 only

Rated 5 out of 5 stars

Very simple, very cool ;).

PDF Viewer(discontinued)

Super! Rated 5 out of 5 stars

In letzter Zeit hatte ich absolut keine Probleme mehr.
Was ich gut finde: Super schnell, perfekte Darstellung, Zoom-Gesten werden richtig erkannt, in Frames verwendbar, sehr schlanke UI aber mit allen wichtigen Funktionen.

Einzig zum Drucken und (teilweise) beim Markieren von Text ist mir der externe PDF-Reader lieber. Aber wirklich nur dann :).
Und selbst das ist mit der Download-Schaltfläche ja nur ein bis zwei Klicks entfernt.

Ich bin schon gespannt, wann PDF.js ein fester Firefox-Bestandteil wird!
