Hello,
I am using Spire.PDF to generate files which I am then storing to the Amazon S3. Once I open generated file (without downloading) with Mozilla Firefox I can only see first page. If for example my document has 5 pages I get 5 first pages displayed. In chrome and when I download the file everything is fine.
I tried to open some other pdf documents with Mozilla Firefox and it was working fine so I guess problem is with the way I am generating these files.
