[Bug] App crashes immediately on launch - v0.11.0 and v0.20.0 fail, v0.10.1 works

[DemonChild212]

Hi WebLibre team 👋

I'm reaching out to report an issue I'm having with the app. First off, thanks for building such a great browser!

The Problem:
Versions 0.11.0 and 0.20.0 of WebLibre crash after trying to open them. They install fine, but when I tap the icon, the app opens and shows a loading screen briefly before closing with "WebLibre has stopped." However, version 0.10.1 works perfectly on my device.

V0.10.2-alpha-5❌:

v0.10.2-alpha-4 ✅:

screen-20260729-182128.mp4

My Device:

• TECNO Pop 7 (BF6)
• Android 12 Go Edition
• 2GB RAM
• 32 bits
• ARMV7

What I've Tried:

• Uninstalling and reinstalling multiple times
• Clearing all data and cache
• Testing multiple versions (confirmed 0.10.2 alpha 4 works, 0.10,2 alpha 5+ fails)

What Changed in 0.10.2-Alpha-5:
According to the release notes, these new features were added:

• uBlock Origin Filter List Management (new settings screen, custom lists)
• Optimized Defaults During Onboarding
• PWA Session Recovery
• Gecko Engine Updated to 150.0.1
• UI changes: "Open in App" moved to main menu, quick-quit option, tab count long-press restored

Hypothesis:
The crash started at version 0.10.2-alpha-5 when Gecko was updated to 150.0.1. This raises the question:

• Is WebLibre testing Gecko 150.0.1 thoroughly on ARMv7 architectures?
• Are there known compatibility issues between Gecko 150.0.1+ and ARMv7 devices?

Given that:

1. ARMv7 has a 2GB virtual memory address space limit
2. Android 12 Go Edition further constrains available memory
3. Gecko 150.0.1 appears designed primarily for 64-bit devices

This could explain why the bug appeared exactly at the Gecko update and not before.

Questions I Have:

1. Do newer versions have higher memory requirements than v0.10.1?
2. Is there something I'm doing wrong, or is this a known issue?

I'd really appreciate any guidance or fixes you could share. I love the idea of WebLibre and would be happy to help test solutions if needed!

Thanks for your time and for the great work on this project 🙏

Unfortunately, without an ARMV7 device I am not able to find the issue. The logs (I received from another user) are just reporting a generic crash somewhere within the gecko engine. Google has stopped publishing images based on the arm architecture around Android 7.0, so it is also not possible to reproduce it via emulator. Need to see if I can find an old arm device around or drop arm support entirely.
