Same STR like from bug #1547911, so I suspect it's not fixed completely and regression range is same.

Make BrowsingContexts stay alive long enough to be detached. r=nika

My steps to reproduce the tab crashes as of Build-ID: 20190506130308 for Nightly (64-bit) on Windows 10 (64-bit):

  1. Create a brand new profile in Nightly.

  2. Launch Nightly using that new profile.

  3. Add extension: either uBlock Origin or AdBlock Plus

  4. Shut down that Nightly.

  5. Launch Nightly using that same (new) profile.

  6. Navigate to https://imgur.com/

  7. Click on an image to go into a story. (Can be video or still picture)

  8. Click on the Back button by the URL bar.

  • Note: TAB CRASHED

This does not happen if in step 3 I had added IPvFoo instead of an ad blocker.

I don't know what makes imgur.com special since I can use an ad blocker and on many sites drill down and later click on the Back button without any crashes.

I'm confirming that bug is fixed, no more crashes in Mozilla Firefox Nightly 68.0a1 (2019-05-07) looking at Reports, so I'm marking this bug as VERIFIED.
Thank you very much! \o/
