1852192 - ClassNotFoundException in Firefox, causing crash of critical com.android.phone process

Status: RESOLVED DUPLICATE of bug 1847141

(Firefox for Android :: Browser Engine, defect)

Description

[Mi5o]

Steps to reproduce

1. Navigate to any site with images
2. Long-press any image
3. Select "Download" from menu
4. Wait until "File downloaded" toast appears

Expected behavior

a. File is downloaded.
b. No application is crashed, not even anything critical in Android.

Actual behavior

File has been downloaded just as requested (which is fine). But at the very same moment, in all cases, another application, a pretty critical "com.android.phone", has crashed. According to my observations, there is 100% correlation between above-mentioned steps to reproduce, and the crash of "com.android.phone", causing Android to disconnect from GSM network altogether.

Workaround

For a couple of times, switching on and off the Aeroplane mode rescues the situation. After several crashes, only a full device restart seems to help.

Device information

• Firefox version: 117.0.1 from Google PlayStore
• Android device model: beyond0lte (Samsung SM-G970F)
• Android OS version: 10

Note: The behaviour have appeared roughly one week ago. Since then, one Firefox update arrived, but things have not changed.

Any additional information?

This ClassNotFoundException error message always appears in logcat when the above-mentioned crash occurs, blaming Firefox as culprit:
