imgur (2020-08)

Description: Image galleries at imgur do not load (show empty pages instead). Some days later, "albums" stopped working.

Cause: the default interface now requires ResizeObserver (Firefox >=69)

Affected versions: All before 2.53.5b1?

• Confirmed with 2.53.3 and 2.53.5beta1pre 20200727210001.
• ResizeObserver support introduced in 2.53.5b1 (see 2.53.5 Release Notes - What's new).

Workarounds:

• Bug 1659778 comment 11: visit https://imgur.com/beta/disable to disable the new interface. Works as of 2020-09-06
