Intl.Segmenter is not a constructor - unable to use Element Web on Firefox ESR 115.12.0esr (64-bit)

[wodny]

Steps to reproduce

1. Try to open the app in Firefox ESR

Outcome

What did you expect?

I expected the app to work.

What happened instead?

Got an exception in console:

Uncaught TypeError: Intl.Segmenter is not a constructor

This API is supported since Firefox 125. I hope that dropping support for Firefox ESR is just an untested (sic!) dependency problem and not a conscious misguided decision.

This happens to me on Debian testing 117.0 too

As per https://github.com/element-hq/element-web#supported-environments we only support the last 2 major versions of each of the listed browsers, for FF this means 126 & 127.

Uh, it's a joke, is it ? You intend to get rid of a large user base, don't you ?

I'm just an individual contributor, I didn't write the policy. I'm merely linking you to it as it says

Please consider how rude this is to close other users' issues :-/

[t3chguy]

It is my job, I am tasked with triage and applying the policies and rules that are set. One of which as linked above says

Issues only affecting unsupported environments are closed

Therefore I have to close it

The ESR's are major versions from a dedicated branch which is important for enterprise use and security-wise. By dropping support for ESR's you are dropping Debian support.

[t3chguy]

The support policy never claimed support for ESR though. https://github.com/element-hq/element-web#supported-environments it says Last 2 major versions of ..., Firefox, not Firefox ESR. The enterprise can keep using an older version of Element until they can upgrade to a browser which does not lack the necessary APIs.

Please mention the policy authors here so they can rethink their position. This is too huge of a problem to discard in 5 minutes.

@t3chguy Would you mind reopening until someone knowledgeable is able to judge ?
