I have the same thing on the release version (v5.8.0.27.g9ba7d) but I'm sure it's linked to the update of Firefox version (76 -> 77) as I noticed the difference right after and didn't update the OS itself.
I guess it's probably the same in your case.

On IRC (#dragonflybsd on EFNet) jh32 came to the conclusion that some pages were still working when the header Accept-Encoding (1) wasn't set and so when the server didn't answer with a Content-Encoding (2). You can check all that with the developer tools (press F12 when loading a webpage and check the headers for the request on / in the network tab). He mentionned an extension : Modify Header Value extension and removing the Accept-Encoding header for all websites as a workaround. 


One guess from kworr is that the code to decompress the content has been moved from the main process, as he said, using Firefox without E10S is unsupported for a long time and that's what the DragonFlyBSD port is still doing.

Hope that helps, but as you said, there's still the Chrome solution.
