I haven't retested this for a few months, so hopefully it still works...

Changing the download location on Firefox for Android requires a visit to the about:config preferences editor. You have to change two different settings to make this work.

First, you need to know the folder path you want to use. An app like ES File Explorer File Manager will be helpful if you do not have a file manager.

(1) Open a new tab to about:config (type about:config in the Awesomebar and tap the go arrow or tap Enter).

You may want to bookmark this for easier future access.

(2) In the search box, type down and pause while Firefox filters the list

(3) Scroll down to browser.download.folderList and tap the preference. Up and down controls should appear. Tap up to change the value from 1 to 2.

(3) Scroll back up and tap the large "+" button to the left of the search box to add a new setting

(A) The name of the preference should be browser.download.dir (this stores the last used directory)

(B) On the right side, tap Boolean and in the popup change it to String

(C) The value depends on the folder you want. For example:

/sdcard/FxDown 

(D) Then click Create (if you are too slow, it may clear and you might have to start again)

If you switch back to your other tab and download something, it should go to the new folder.

Any luck?

I want to be asked everytime like my desktop version. I want different things to go to different places, like statements to go to a different directory for each company or reference documents to a different directory. I want to browse and create directories on the fly. I do not want to have to restrict downloading to my desktop.

On desktop versions of Firefox, the options/preferences page setting to ask you every time makes this corresponding change in about:config:

browser.download.useDownloadDir => false

I haven't tested that on Android; it's possible that the necessary dialogs don't exist in the mobile version.

The dialogs do not exist in the android version. There are lots of dialogs that do not exist in the android version greatly reducing the value of the android version of firefox. From a user's standpoint, it is like they did a brand new product mostly from scratch, but kept the worst parts of the original code ;)

Hi Multicsfan, did you want to give input about possible changes in Firefox?

That should also be somewhere in the menu.
