Some Web pages has files attached to it with the purpose to download a file associated to a link; download this files is an easy task to accomplish using the desktop version, it is enough to do a right click on the link and select the "Save as" option from the contextual menu. Firefox Android version seems not to have such feature. I order to download a file I have to use Opera for Android. Try to download this free file from this site and you'll see what I mean.j7 https://brainwavelab.blogspot.com/2007/09/un-dia-de-tormenta-60min.html?m=1 Thanks! P.S.
