OK!
Please make sure, you become aware of Firemath updates.

Thanks
I installed firemath with the download I did with internet explorer. Rightclicking the file and asking to install it with firefox did the job. Everything seems to work fine.

Maybe you find help on one of these pages:

Also, if you are able to open the file with IE, you could try to save it to disk and install it via File->Open within Firefox.

Thanks for the quick reply.
I disconnected my firewall, but had the same problem.
with internet explorer there was no problem downloading the file, but how to install?

For your information this was the information i got ( in Dutch)

Firefox kon het bestand op

https://addons.mozilla.org/nl/firefox/downloads/file/38044/firemath-0.1-fx.xpi

niet installeren omdat: Ongeldige bestandshash (mogelijke downloadcorruptie)
-261

This has nothing to do with Firemath. It is either a bug at addons.mozilla.org or you are behind a firewall, which prevents installation of "experimental" addons.

Impossible to download firemath. There is a hashfault.
I suppose that at this moment nobody can download it.
