1909993 - Massive lag and hanging of the keyboard during text input on some web pages

Status: UNCONFIRMED

(GeckoView :: IME, defect)

Description

[u757895]

User Agent: Mozilla/5.0 (Android 10; Mobile; rv:128.0) Gecko/128.0 Firefox/128.0

Steps to reproduce:

1. Go to https://xdaforums.com. The bug appears in many websites, but i use this Site as example.
2. Click on ,,Register"
3. Try to write text in the entry boxes

Actual results:

I click on a letter on the keyboard, but Firefox does not respond. When I try to activate the Caps Lock key, it is immediately deactivated again. If I want to exit the app, the keyboard is also not closed correctly due to the lag and is still displayed on the home screen. Tested several keyboard apps, same or similar behavior everywhere.

Expected results:

Text input should simply work normally.

Thanks for reporting this issue. Can you please record a Firefox performance profile and share the link in this bug?

The profiler is built into Firefox, so you don't need to install any extra debugging tools. Here are the instructions:
