Hi, thanks for your report.
I tried to reproduce your issue on the latest version of Nightly 68.0a1 (2019-03-27) but I wasn't able.

Devices:

• Motorola Nexus 6 (Android 7.1.1);
• OnePlus 5T (Android 9).

Do you have some specific add-ons installed or different settings on the app? If you have any additional information regarding this problem, please let us know Also, can you provide us a video with your issue? I'll wait for your updates, thanks.

Mariano, can you confirm you're using Firefox for Android? What version, and on what device? How often do you run into this problem? Is it 100% consistent, or it just happens randomly?

I think I have seen this on Reddit as well.

Is it a Selection issue with the Accessibilty Caret?

Unrelated to text selection. At least not directly.
