Firefox is only saving 8 light-weight themes. Supposedly this was fixed in February, but I still cannot save more than eight. Is there a new fix or workaround?

Tonight we found a site called getpersonas.com. We found several we liked and started saving, then later realized Firefox 3.6.3 is only saving the last 8. I checked the forum and saw a bug report related to this, but it was also reported as fixed, but I still have the problem and I see no workaround posted. == This happened == Every time Firefox opened == I started saving personas that were saved as themes.
