This is not a 'new' review, but a response to the Developer.

Sorry for not responding sooner, my OS is Windows 7 Ultimate (SP1) x64. The downloads that were failing were all .exe files, and it doesn't matter where it came from, it always gave the error.

I have no idea why it does it, because it works perfectly fine in 3.4.3 but fails to work in 3.5.x.

Browser versions I tried it on were FireFox 25.0.1 and Firefox 28.0.

Esta análise é para uma versão anterior do extra (3.5.1.1-signed).  Este utilizador tem 2 revisões anteriores deste extra.

Anything relevant in the error console?
(Maybe you'd better send me some e-mail so this doesn't spoil the reviews :-))
