Hello there! At our company we have started to deal with an issue in the latest iOS (17.5) version.
It looks like the background script of the extension becomes unresponsive after a short amount of time (around 30 seconds) after performing more than one request to it within a range of 1 - 4 seconds.
How it can be tested? Pretty simple example:
// content.js
const t = 4000 // Using less than 4000ms makes background script unresponsive
async function requestNext() {
return browser.runtime.sendMessage({ greeting: "getNext" })
}
setInterval(async () => {
const n = await requestNext()
console.log("current is: " + n)
}, 4000)
// background.js
let counter = 0
browser.runtime.onMessage.addListener((request, sender, sendResponse) => {
console.log("Received request: ", request);
if (request.greeting === "getNext") {
counter++
sendResponse(counter);
return true
}
});
Whenever the browser.runtime.sendMessage is executed too fast the background script will stop working.
As far as we have been able to check this only can be reproduced after 17.4.1
