Part 2: Disable Sound in Firefox. When a web page in Firefox starts to play audio, you can click the speaker icon to toggle the sound for that one tab off, and click it again to toggle the sound back on. Part 3: Disable Sound in Microsoft Edge. Just like other browsers, Microsoft Edge also uses a speaker icon to indicate which tab is playing sound.

For the volume, unlike Chromium for example, firefox synchronizes it's pulse stream with the volume level of whatever source you have opened (and if that source stores it's volume levels, it will be applied accordingly) e.g. if you open up youtube or most other streaming pages, the volume in that specific player will be remembered across sessions in your account, and that's what firefox replicates over to the pulse stream.
To properly assess whether that's the case here you might want to point out on which specific pages you are seeing this 'default volume'. I'm not sure whether it's possible to prevent Firefox from this synchronization so that the volumes would be distinct again, but I haven't looked into it much either.
When a page is loaded, Firefox will cache it into the hard disk so that it doesn’t need to be downloaded again the next time it is loaded. The bigger the storage size you cater for Firefox, the more pages it can cache. Before you increase the disk cache size, make sure that browser.cache.disk.enable is set to “True.”. I think I see the difference. When I load the MP3 and OGG files directly into a tab, Firefox uses the video player to play them. That player has the volume control bar. That would explain the difference. After looking at the earlier thread (HTML5 audio player has no volume control), I think the answer is.
No, I've looked into it. It's a known bug.

Firefox Volume Control Add On
It's unbelievable one can't set a volume level for a specified application, unless you adjust it over and over because it can't remember the level you set. And the application here is Firefox. Quite annoying.
Volume Control In Firefox
You can adjust the volume for individual output sources in Windows 10 using the volume mixer. To open the audio mixer, right-click on the speaker icon in the notification tray, and select Open Volume Mixer. Here check the audio levels for Firefox and set it to max volume if set otherwise. Now you should be able to hear audio from Firefox now. Once you launch an app that starts playing sound, for example Firefox playing a YouTube video, a new bar appears that allows you to configure per app volume: Ideally the new volume slider visible in the screenshot above should allow you to control volume of Firefox without affecting master volume or sound level of other running apps.
