Firefox "error" when open in terminal

[yuanhao]

Hi, I am on KDE, I am using firefox as my browser and it works with no problem no matter when I open it with launch menu or from terminal.

But when open from terminal, although it works perfectly, it comes with this messages when I open it:

[yuanhao@yh-G14-GA402RK ~]$ firefox
[GFX1-]: glxtest: VA-API test failed: failed to initialise VAAPI connection.
ATTENTION: default value of option mesa_glthread overridden by environment.
ATTENTION: default value of option mesa_glthread overridden by environment.
ATTENTION: default value of option mesa_glthread overridden by environment.
ATTENTION: default value of option mesa_glthread overridden by environment.
Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs

and after I close firefox it then output this:

Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs
[2022-08-26T17:59:55Z ERROR viaduct::backend::ffi] Missing HTTP status
[2022-08-26T17:59:55Z ERROR viaduct::backend::ffi] Missing HTTP status
[yuanhao@yh-G14-GA402RK ~]$ 

I haven’t had any issue with firefox but I am wondering what is the message, and can I ‘fix’ it if it is some error?

A lot of programs spit out meaningless (to us) error messages when run from a terminal. They may mean something to the developers.

Just ignore.

But I checked my laptop (vanilla arch) it does not has the last two error message…
so if it the last two error lines are something meaningful?

As long as it is functioning correctly no need to worry. It seems it is related to an update listening and only on HTTP so it may be that security is preventing HTTP connections for an updater in favor of HTTPS connections (best guess). Regardless, carry on, nothing worrisome to see here.
