[🐛 Bug]: Selenium Manager downloads x86_64 firefox binaries on ARM Linux

[lprimak]

What happened?

Firefox is available for Linux ARM (mac, OCI/ampere, ARM/gravitron etc)
However, Selenium Manager downloads the x86_64 version leading to failures

High Impact

This issue makes impossible to run Selenium tests on Ubuntu-based docker images without going through gymnastics of installing firefox manually.
This is difficult because it requires snap, which doesn't work in Docker containers

How can we reproduce the issue?

Any Selenium run on arm64 linux with firefox driver will reproduce this.

Did a bit more research, and I don't see a "download" for Arm64 Linux on Firefox' site at all. Perhaps they don't offer supported versions.
Still, I think Selenium should give an error / log or something instead of silently downloading x86 version.

Alpine linux offers firefox in their apk package manager, but ubuntu, debian, etc. do not.

@bonigarcia do you know if SM checks this?

Indeed, Firefox is not distributed for ARM Linux. On the other hand, Selenium Manager for Linux is only compiled and distributed for x64. Maybe Selenium Manager should fail in this scenario, but I never tested it.

[diemol]

True. ARM Linux is still "rare," so we do not have the tools to test it yet. I will leave this open and see if someone wants to help add this validation. Right now, this is a low priority.

I did some more research, and Mozilla is working on new distributions for Arm Linux.
See https://bugzilla.mozilla.org/show_bug.cgi?id=1678342

I didn't realize that Selenium Manager is only compiled for x64, I guess it was running in the emulation mode in my tests.

Playwright supports both Chromium and Firefox for Linux arm64.
