Firefox - can't install add-ons or perform downloads- XP

alanrowell

Firefox has stopped allowing me to do downloads or install add-ons.

When I try to install an add-on I get the message

Firefox could not install the file at

https://addons.mozilla.org/firefox/downloads/file/104463/xxxx/xpi?src=api

because: Download error
-228

I've tried going to the Mozilla website and download them direct then dragging them into the add-on window - whilst I can download & save them I can't successfully install them.

When I do a download I get the message

R:\Temp could not be saved, because an unknown error occurred.

Try saving to a different location.

where R is an old drive that I removed & didn't replace a while ago as it had failed.

I've tried the suggestion in this but none work. I've also tried removing Firefox completely and reinstalling but with the same results.

Any ideas short of rebuilding the computer from scratch?

Definitely start a new firefox profile (weird as it sounds, even uninstalling doesnt completely remove firefox which is why a new profile is required)

Try creation of another profile

Tried removing profile didn't work - and in any case the FULL removal of FF includes getting rid of all profiles.

Found the solution - nothing to do with FF, everything to do with [url=http://ask-leo.com/how_do_i_change_the_location_of_windows_temporary_files.html[/url]Environmental Variables[/url]
