Úgy néz ki tényeg a mesternek van igaza:
"Is Opera available for 32-bit Linux?
The latest version of Opera for Linux is 64-bit only, based on what most Linux desktop users have installed. If you have a 32-bit Linux installation, you can continue to use Opera 12.16.
All new PC-compatible hardware from the last five years should be capable of running a 64-bit Linux distribution."

Szóval, marad a Tűzróka és Chrome páros.
