Muy completa y eficiente

Apart from the empty modal Window that it seems to open on restart following a Firefox crash, this has saved my bacon more times than I care to remember.

I'm crap at keeping the number of tabs to a reasonable number and this helps me keep them around.

Много удобно и полезно. Някой път спасява положението. Като имаш отворен private window и нормален, ако затвориш първо нормалния и после private, firefox не ти запомня сесията, а това я помни :)

A really useful addon. It helps me saving tabs in sesions for later consulting while I can focus in another tasks without overloading the system memory.

Thanks of created this addons, It saved my life a few time: Firefox closed while opening 2 windows, it can't use the built-in restore feature since it only able restore single window. I've sent 5 dollar to you just now :)

btw, Just now got indexedDB issue, I don't have to delete storage folder, I just have to goto about:profile, open the profile+cut that folder, then restart web browser and the error gone

Permite volver a páginas ya visitadas, así como guardar sesiones con múltiples tabs

nice manager, works perfect.

Just what I needed :)

simply the best DL- Manager!

I seems to be working fine so far. But could you add support for "Panorama View" addon? Right now all tabs of each groups are merged into one group which makes the tab groups useless.

Please put it in the new firefox version

Alles was man braucht und nach mehreren Updates noch besser als der Vorgänger!
