I noticed the problem is not specific to Comodo products. Torch and SuperBird, both based on Chromium, are equally unable to translate. However, others are doing the job just fine: Slimjet, Yandex, SRWare Iron and obviously, Chrome.
I don't like the idea of adding extra plugins just to do the basic job the browser should be doing in the first place, and maybe not as good. Combine with the big gap between last Chrome and CD/CS versions (I know they promised faster releases in the future, I'm still waiting), and the reshaping of CD to look like Chrome (what a nice browser was before!), it's time to move on. I will not abandon all hope, and keep an eye on what is going on here, but for the time being at least, I will switch to another browser as my main.
Thanks for your reply.
