How do I stop - "Application/json" file down load popup?

Update - Here's another anomoly. If I use the search pane in the tools header (which is a mini Google search pane) first, then, modify the search text in the new pane that opens, the problem doesn't happen.
For instance, if I type in "Google" in the tools search pane, and press enter, the full Google search pane opens. From here I can type in anything, any number of times and the problem doesn't appear.

It only seems to happen if I use just the main Google search pane in the first instance.

That is very weird. Have you tried resetting Firefox to the default settings? It's almost like it's been changed so it doesn't know how to deal with .json requests therefore it just assumes it's a file that it should prompt you to download.

@Fligi7 - completely wiped FF and reinstalled. Also happens with Chrom.
@boohbah - As I mentioned above it doesn't happen in the Google tool bar pane, but, if I try to do a 're-search', ie. change the critria in the main page search pane, that's when it happens.

Problem is with changing from UK to US will be different search results based on that country. BUT, worth a try!

I don't want to change my browser if I can help it, but, this is really anoying and has been going on for some time now despite FF updates.

Even if you've uninstalled and reinstalled Firefox, have you tried resetting the settings per above?

I have the same problem because i've installed an add-on called FastestFox. So I removed it and I haven't had a popup since. Try disabling your fastestfox and see if that works

@FliGi7 - As far as I can tell all settings are back their default.
@sherockoc - I know what you mean about FastestFox, but I've uninstalled all plugins and addons.

Looks like I'll have to go over to iE9, didn't seem to happen on that.

Many thanks for all your help though Guy's, much appreciated.

I have this same issue on an xp machine, but not the Win 7 install which has many more add ons.
Very odd problem and quite annoying

Right, but did you actually follow the instructions for resetting them, per the link Restore the Default Settings in Firefox Without Uninstalling It - How-To Geek ?

I'm only pushing this issue because following those particular instructions, even if you think you've personally reset everything, could be one of those fixes that you don't quite understand but works.

I'm pretty sure now this is a FastestFox problem. Even though I uninstalled it it wasn't until I wiped the whole reg of it that the problem disapeared.

Haven't reistalled............ no more json problem.
