There were some important fixes done. But you will not noticed them unless you clear your cache for gnutella

In Firefox settings > Privacy & Security > Cookies and Site Data > Manage Data …
There is a search box at top, simply type in gnutella and choose Remove Selected (after you select them.)

For Chrome it appears you cannot do it per site (perhaps I simply can't find the option.) But it does allow you to remove cookies from a previous period. Either 24 hrs or 7 days. The latter might be best. The fix seemed to work for Chrome.
