I've tried on master, debug build and no problem.
Also no problem on master fennecNightly build signed with my own key.

Thanks for reporting. I'm unable to simulated the issue. Also I couldn't find any crash stack traces in the logs. @softvision-miralobontiu could you go to "Settings" -> "About Firefox Nightly" -> "Crashes"? There you can can find the stack trace that can help us to determine issue. Could you send the stack trace please? :)

@Amejia481 I'm able to simulate on 77.0-beta2 on XZ1.

@hakkikaancaliskan Do you know if the code in branch v5.1.1 is the equivalent to 77.0-beta2? Thanks in advance :)

[hakkikaancaliskan]

@Amejia481 Yes, it is.
Edit: Nooo :) 5.1.0-beta3 = 77.0-beta1-2

I think I found the issue: The version of geckoview beta that that build is using doesn't have support for blob urls, but the actual version of geckoview beta has.

Hi, thanks for the testing here! The 5.1 branch has been so long in releasing (since ~May 18), so it's pretty far behind in a lot of the changes that have since landed.

This should be fixed in the 5.2 release going out this week, please re-open if 5.2 does not fix it. This unfortunately will not be rolling out to the 77b build yet until our next release cycle.
