Hallo, Ich habe ein mir unbekanntes Problem. Unter Firefox, Linux Mint. 19.1, was auf 2 Speicher installiert, zur Sicherheit, ist folgendes aufgetreten: Plötzlich kann ich Datenbanken von Joomla auf der einer SSD Samsung 850 Plus nicht aufrufen, auf der anderen King SSD M.2 über PCIe - im selben Computer -ist es möglich. Der Fehler ist erst 1 Tag alt. Ich werde in meinen Arbeiten daran gehindert, nicht durchführbar!

Da ich sehr unfangreiche und wichtige Chronik verfüge, möchte ich nicht diese Löschen. Leider hat Firefox nach Jahren immer noch keine Möglichkeit diese Chronik zu speichern eingeräumt, oder es ist viel zu umständlich und daher nicht durchführbar. Firefox bekommt leider nur einen Stern von mir. Eric - 04.11.2020 - [email]

[Locked as a duplicate of https://support.mozilla.org/en-US/questions/1311779. Please follow up there, thanks.]


Here is my code:

<script> async function updateSrc(){ var media=document.getElementById("media"); var shareAudio=document.getElementById("audioSrc"); var shareVideo=document.getElementById("videoSrc"); shareAudio=shareAudio.options[shareAudio.selectedIndex].value; shareVideo=shareVideo.options[shareVideo.selectedIndex].value; await getStream(shareVideo,shareAudio) .then(stream=>{ if (media.srcObject!=null){ var trackList=media.srcObject.getTracks(); for (var i=0;i<trackList.length;i++){ trackList[i].stop(); media.srcObject.removeTrack(trackList[i]); } media.srcObject=null; } media.srcObject=new MediaStream(); stream.getTracks().forEach(track=>{ media.srcObject.addTrack(track); }); }) .catch(err=>{ if (media.srcObject){ var trackList=media.srcObject.getTracks(); for (var i=0;i<trackList.length;i++){ trackList[i].stop(); media.srcObject.removeTrack(trackList[i]); } } media.srcObject=null; console.log(err); }); } function getStream(shareVideo,shareAudio) { templateConstraint = { "video": { "width": { "min": "640", "ideal": "1280", "max": "1920" }, "height": { "min": "480", "ideal": "720", "max": "1080" } }, "audio":true } var constraints={}; if (shareVideo=="yes"){ constraints.video=templateConstraint.video; } if (shareAudio=="yes"){ constraints.audio=templateConstraint.audio; } return navigator.mediaDevices.getUserMedia(constraints); } </script>

Share Video <select id="videoSrc" onchange="updateSrc()"> <option value="no">No</option> <option value="yes">Yes</option> </select>
Share Audio <select id="audioSrc" onchange="updateSrc()" autocomplete="off"> <option value="no">No</option> <option value="yes">Yes</option> </select>

At first, when I change the "share audio" value to yes, both Chrome and Firefox can play the sound.

After that, I close the browser. And then open a new browser, load the page.

if I change the "share video" value to yes, and then change the "share audio" value to yes, the Firefox browser cannot play the sound, even I rebuild the video tag media stream.

So how can I fix the problem?

Please continue here: [/questions/1314933]
I am running a WIN10 Pro 20H2 PC with Firefox 83.0. All software up-to-date. My Internet connect is cable with a U.S. IP location.

All O.K, until I open "https://www.newegg.com/" with my default Firefox browser, which always opens "https://www.newegg.com/global/uk-en/".

Opening the same "https://www.newegg.com/" URL from the same password manager entry explicitly using Chrome or Edge I get to the desired U.S. location.

Does not occur on my other PCs.

Firefox is changing the URL so that I am always going to the UK location?

Can't find where this is happening. Can anyone assist?
