Amazing! Do you know if anyone tried to run this on a Sage?

After getting that Kobo I realized that my hyper specific reading needs require a web browser with extension support (in particular support for Yomitan or similar dictionaries; the built-in dictionary functions on e-readers are awful for most non-English languages even with custom dictionaries, and KOReader isn't any better in that regard)

Not that I know of, and it isn't listed as a supported device on the pmOS wiki: https://wiki.postmarketos.org/wiki/Category:Kobo

I can run Firefox on my Kobo Clara HD, but it's not a pleasant experience. It is very, very, very slow.
