Bump Firefox version to get full happy eyeballs capability

[moderation]

There is a helpful presentation at Rollout of Happy Eyeballs v3 in Firefox. The latest Firefox nightly has some of the Firefox specific implementation details. The version is 155.0a1

Current latest Glide with Firefox version 153.0b5

Happy Eyeballs v3 is a good reason to investigate a Gecko update, but I would not treat the Firefox version string as a drop-in feature switch.

Glide needs to update the actual GeckoView/runtime dependency and verify that the networking implementation, Android API level, build tooling, and application patches remain compatible. A Firefox Nightly version such as 155.0a1 may contain experimental behavior that is not present in the corresponding stable/beta runtime or may require patches that Glide does not yet carry.

I would stage the work like this:

1. Identify the GeckoView package and exact revision currently used by Glide.
2. Build a branch with the smallest supported upstream bump.
3. Add connectivity tests for IPv4-only, IPv6-only, dual-stack, slow IPv6, and a failed first address.
4. Verify redirects, proxies, DNS behavior, TLS, downloads, and captive portals.
5. Compare connection latency and failure recovery against the current 153.0b5 build.
6. Keep the upgrade behind a release branch until the Android device matrix is green.

The Happy Eyeballs behavior should be measured from actual connection attempts, not inferred from the browser version. If the needed code is only in Nightly, it may be better to wait for a supported GeckoView release or backport the narrowly scoped networking change than to ship an otherwise unstable browser engine.

Thanks for the insight into the diligence and care taken to incorporate upstream Firefox releases. 45265e4 bumps the Firefox version to 154.0b10 which incorporates the Happy Eyeballs configuration. It defaults to not being enabled but can at least be enabled via about:config. I'm looking forward to the 0.1.64a release.
