413 Error - Entity Too Large for Firefox

[jimorc]

I have installed Perfecty on my Wordpress website. In testing, I have signed up for notifications on two systems: Windows 10 PC with Edge browser, and Android 11 tablet with Firefox browser. I get notifications on the PC, but no notifications on the tablet.

Here are the relevant Perfecty log entries:

I have wp-cron.php turned off in wp-config.php. Instead, I run a cronjob every 30 minutes to execute wp-cron.php.

Hi, this is an active issue reported for Firefox on Android in our underlying library: web-push-libs/web-push-php#62

From the issue:

Apparently Firefox for Mobile has restrictions of payload length.
I filled an issue on mozilla-services/autopush#748 since it's not a standard behavior.
In the meantime, you can disable automatic padding.`

It looks like we need to tune the automatic padding from the push library which is something we don't allow to the users at the plugin level.

So at this point, there is nothing I can do? I guess I can live with losing the 0.5% of all browser users (the percentage of people who use Firefox Mobile).
