ESR so out of date that Turnstile no longer works.

Hi

I recommend that you also file this at https://webcompat.com/ who may be able to contact Cloudflarw directly.

ESR is is not based on any specific version per say. Right now there are three ESR channels as in the new major version Firefox 153.0 ESR based on the Firefox 153.0 Release, Fx 140 ESR and the still being updated Fx 115 ESR for the EOL Windows 7, 8, 8.1 and macOS 10.12, 10.13, 10.14 OS users to still have a secure web browser to use for a while still.

Firefox 140.13.0 esr is based on the old Firefox 140.0 Release but with security and stability fixes since. The Fx 140.17.0 esr is the last planned update for the older Fx 140 ESR.

OK, it's done...

I still don't see how that's going to be any more useful than the forums. I would hope that a company as big as Cloudflare could check their forums.

aaaaand it was auto closed: https://webcompat.com/issues/229815

How does https://browser-compat.turnstile.workers.dev/ look for you? (It has some extra debug outputs when you're completing it…)

There's also https://challenges.cloudflare.com to verify you can connect to that host at all… in case the issue is elsewhere.

https://challenges.cloudflare.com shows a checkmark, so I guess it works.

The thing is I have tested a newer version of Firefox and it works. So I would suspect that it is a problem only with ESR.

So it seems to work when I start a new profile... (This did not work a week ago).

The only difference is that Firefox outputs the following into the terminal when using the bugged: ``` libva info: VA-API version 1.22.0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so libva info: Found init function __vaDriverInit_1_0 libva error: /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so init failed libva info: va_openDriver() returns 1 ```

Ok, I fixed it, but lost all my non-pinned tabs...

Followed this guide to get everything to be as it was, and now the Turnstile is working: https://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Can't seem to figure out where the tabs are stored.

If you restart the existing profile into Troubleshoot Mode (from Help menu), does the "unknown error" get any better on that turnstile test page?

If you compare the two profiles' about:support in regards to WebRender, GPU drivers, video codecs etc. are there any obvious differences?

Tabs as in sessionstore? There's some more uptodate articles:
