Also seeing this consistently, thanks for opening an issue @themr0c -- I've been meaning to.

For clarity, the entire font is not loaded and the default serif font is shown. Errors in browser console:

@slemeur I worked on reproduction this issue and I see - issue is reproducible on the Firefox 67, but is not reproducible since Firefox 68.0.1. Do we have any strategy about minimal Firefox version support? I mean when we confirm that we are going to fix some bug, because it is reproducible for some supported Firefox version, if it is reproducible for older version we apply recommendation for users to use newer Firefox. Because it's really time consuming trying to figure out issue is actual or not, and there a lot of Firefox versions: https://ftp.mozilla.org/pub/firefox/releases/ . What do you think? Example of the browser support note https://github.com/xtermjs/xterm.js#browser-support

[amisevsk]

I think as long as things work on the latest stable version of Firefox that's commonly available, it's fine. What's concerning is that we don't know what changed between firefox 67 and 68 that fixed this -- we don't link to a bug that explains the issue. Is Che doing something wrong and it just happens to work with a new Firefox, or was it a legitimate Firefox bug that caused the css loading issue? IMO unless there's a bug we can point to in Firefox that causes the issue, there's something wrong with Che.

I don't like issues that resolve themselves without explanation.

Issue progress update:

For such kind errors:

I created pr eclipse-che/che-theia#551 . Also I found that font exception could spawn side effect: not all che-theia icons is loading, especially for project tree view.

[AndrienkoAleksandr]

Issue progress update:
I created pr to fix one more exception from webview: eclipse-theia/theia#6581
After merge both pr's che-theia log in the firefox should be clean.

[AndrienkoAleksandr]

Related pr from upsteam theia:
eclipse-theia/theia#6465

[AndrienkoAleksandr]

Faced with bug. Webview with https doesn't work for Firefox in the incognito mode. https://bugzilla.mozilla.org/show_bug.cgi?id=1601916

[AndrienkoAleksandr]

Reworked webview work with https and with latest Firefox, but doesn't work with latest long term Firefox esr 68.3.0esr. Because latest esr doesn't support service worker...

[AndrienkoAleksandr]

See more about service worker on the Firefox esr https://bugzilla.mozilla.org/show_bug.cgi?id=1547023 Task is not completed, so issue in the Firefox side.

[AndrienkoAleksandr]

With latest Firefox, welcome plugin looks like:

Yes we don't have logo but it's another one issue #15324
