Details

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:76.0) Gecko/20100101 Firefox/76.0

Steps to reproduce:

  1. Set MOZ_FORCE_DISABLE_E10S environment variable and run Firefox
  2. Open https://www.google.com/

Actual results:

Garbage text is drawn

Expected results:

Page content is drawn properly

It seems to happen with pages with Content-Encoding: gzip (or br, and so on), Firefox tries to render content without decoding the compressed data. When network.http.accept-encoding and network.http.accept-encoding.secure is set to blank, the problem goes away.

Occurs with 77 beta and 78 nightly. 76 isn't affected.
Good with nightly build 2020-04-24-21-44-33, https://hg.mozilla.org/mozilla-central/rev/db2e1d780268ab0a7dca1ea1ca81febcb33e926e
Bad with nightly build 2020-04-25-09-49-23, https://hg.mozilla.org/mozilla-central/rev/d8a8178627c4fab05f1eb46ee40f55db207c7c18
