What does "System Information" in Joomla's backend tell you about "User Agent"?
I think that something is manipulating the agent string when using the Browser class. Normally Firefox sends always a string like Firefox/x.y
.
In your case it looks like it's only Firefox/x
(without the dot between numbers).
BTW: I don't think that this issue will be fixed in Joomla 3 because it's not a security issue.
Hi,
Well it looks the same as your output:
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/109.0
But it seems as if the error occurs a bit random.
I also get a similar message from "WebClient.php": PHP Warning: Undefined array key 1 in /libraries/vendor/joomla/application/src/Web/WebClient.php on line 405 It seems to appy to a Chrome-client?

I'm asking because Joomla 4 uses the same code in class Browser
.
Is it a warning that you see in your error log file "coming from somewhere" or when you visit your Joomla page yourself with your Firefox browser? Other words: You are sure that your browser triggers this warning?
I never have seen a PHP message like this and work a lot with Firefox, Joomla 3 and 4 with debugger tools that display warnings, too.

Yes, the second part concerning Chrome. See also https://github.com/joomla-framework/application/issues/112
Hi,
It has occurred 26 times since september 2022, 24 times at line 691 and 2 times at line 620 – and this is on my lab site that has bee visited by me and ”ACYMailing”- , ”RSJoomla!”- and ”ChronoEngine” -support during this time. So it could be their browsers.
I obviously visited the site a lot more that 26 times.
The live site only has 1 entry for line 691 – but I missed out on logging for january.
So I suspect it has something to do with the shift to PHP8.0 that have runned for a longer time at the lab-site and just recently (january) been applied to the live site.

Yes. In PHP7 it was a notice
(often ignored by error_reporting
). Now it's a warning
.
If you can check your web server access logs what the user agent is we would know if it is just a "new" one (like the Chrome case) or just a "stupid" one.
Hi,
Is this helpful?

I am closing this for the reasons stated above. Obviously we can't do anything about faked user agent strings. It can always be reopened if someone disagrees with that
Steps to reproduce the issue

Actual result
PHP Warning: Undefined array key 1 in /libraries/src/Environment/Browser.php on line 691
