Curtis, - Are you a bot? - Here is the information you requested: Sony Xperia ZR C5502 Android OS version 4.3 Idea Cellular (although I am not sure why it is relevant to the question above)

Hey,

No, I'm not a bot :) The reason I said that was because you tagged your problem as "Firefox OS" as opposed to "Firefox for Android".

Curtis

Open the Android OS settings. Select Apps. Select Firefox from the list and there will be a move to sdcard option. This will move all the application files of Firefox to the sdcard.

@Curtis Parfitt-Ford

Nope. It is Firefox for Android. Where did I tag Firefox OS? Before posting this question I was lead through a questionnaire where I did select Firefox for Android. I understand the difference between Firefox OS and Firefox for Android.

It is no longer possible to move applications to SD card. I believe this change was done after 4.2 Jelly Bean. (Samsung seems to have some workaround for this but Sony does not)

And even when that option is used, Firefox still occupies a lot of internal memory. (I also have a Sony Ericsson Live With Walkman on 4.0 Ice Cream Sandwich in which the Move to SD card option exists. That option only moves a limited amount of things to SD card.)

I am attaching a screenshot of my phone's internal memory occupied by various applications of which Firefox tops the list.

Yes that is expected it will use space for the browser cache and user profile. Both are kept on the main partition for security.

How to override this security setting? I am not that concerned about security. I would rather have some usable free space in my internal memory.

This will be felt very badly in devices with low internal memory.

It is not possible to the best of my knowledge.

Probably possible through indirect means which would need rooting the phone. Possible candidates are Link2SD which will move the actual Firefox files to a 2nd partition on the SD card. Folder Mount of which I have heard but not yet tried could be another option.

Having a built-in option would be nice without having to modify the phone firmware itself which might be a greater security risk overall.

Can I request this feature and if Yes then where?
