I’m thinking this may be a Sandboxie conflict. Is it possible that you are double sandboxing Firefox? Once in CIS and again in Sandboxie

No double sandboxing mouse1 ;), maybe there’s a conflict with something…but It’s not so easy to understand…I noticed that actually i can download little files (pdf, text, images)…but NOT several mbs files (installers).
In that case you can se the temporary .exe file on shared space folder, but firefox crashes immediately…

I have received a PM from wonderlust76 stating that he installed a different version of Windows and is no longer experiencing this issue. Therefore, as nobody else has reported this as well, I will move this to Resolved.

If anyone else experiences this issue please reply to this topic and I will re-open this.

Thank you.
