Error when accessing mega.nz

When I try accessing mega.nz with Tor Browser 6.0.1, I get the following error message in a popup window:

An error occurred while loading MEGA. Filename: Exception: InternalError: allocation size overflow

The problem doesn't happen if I try with an older version of firefox (routed via Tor).

Does this happen with 6.0 as well (https://dist.torproject.org/torbrowser/6.0/)? On which platform? Is it enough loading mega.nz in my browser to see the problem or do I need to be logged in? Is the browser still working afterwards or does it crash?

I think this is #19400 (moved). We have a user on the blog who confirms using a clean 6.0.1 fixes the problem for them.

I've just updated to 6.0.2 and the problem remains.

Then I tried the suggestion in https://trac.torproject.org/projects/tor/ticket/19400#comment:28 (remove the cached asmjs files which you can find under .../TorBrowser-Data/Browser/*.default/storage/temporary/) and the problem disappeared.

(Yes, I had alread visited mega.nz, so I had cached asmjs files)

I think you should include that cleanup suggestion in the release notes, because just updating to 6.0.2 won't fix the problem.

Could you test that again on your machine? Taking a clean 6.0.1, going to mega.nz and then updating to 6.0.2 and doing the same (see: https://dist.torproject.org/torbrowser/ for a 6.0.1)? The fix for #19417 (moved) should prevent your problems.

Are the cached asmjs files in 6.0.2 still there after you accessed mega.nz, closed Tor Browser and restarted it?

Oh, maybe that is due to you having disabled Private Browsing Mode in your Tor Browser? (clicking on the green onion -> Privacy and Security Settings... -> Don't record browsing history or website data (enables Private Browsing Mode) would show you the latter unchecked)

user disappeared?

Yeah, and "fixed" by disabling asmjs in 6.0.3 and the alphas anyway.
