Currently we at F-Droid build Fennec for three hardware platforms: ARMv7, x86 (Intel) and ARMv8. There are a lot of people with 32-bit and 64-bit ARM devices around, but are there any with Intel-based ones? Intel Atoms could be seen, for example, in Asus Zenfone 2 line (from 2015) and cheap noname tablets.
If you use Fennec on an Intel (x86) phone or tablet, please leave a comment. If noone needs x86 version, we’ll drop it.
P.S. The question is about x86 only. We will continue to build Fennec for ARM (both 32- and 64-bit variants) by all means.
