It would be nice if Opera could step on the plate and release sooner the 32 bit Opera for Linux in the developer pipeline.
The current stable and beta version is only available for 64 bit.
It Would be Great! I Agree! Opera should take part on Linux Ecosystem
opera-beta_34.0.2036.16_amd64.deb is already working with Firejail (0.9.34-1) in Ubuntu 15.10 if it is invoked with the following --noprofile option :
$firejail --noprofile opera-beta
Firejail is a must especially if you have installed Flash-plugin in Opera.
