Firefox Community Forum

This is an exact copy of a question with the same title by Steve Ediger, of August 2022, now archived.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, the details appear on the form but get removed almost instantly.

I am in UK. It was working until recently.

None of the earlier answers have helped.

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works

ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

I get this multiple times per week and then have to delete all amazon.com cookies and relogin to everything.

Hoping someone has a solution as I would prefer to continue to use Firefox but this is getting very annoying.

I use Firefox 134.0.2 (aarch64) as my primary web browser. I only have it open 15 minutes and I am receiving alerts that my RAM memory is being consumed by it. I am using a Mac Mini Pro M2 chip with 32GB of RAM . I have just opened Firefox to discover it is taking 10GB of that RAM. It is the most voracious user. If I have it open longer it gets up to 16GB of memory. I often have 5 or 6 tabs open when I am working. My other browser is Chrome that barely makes it to 1GB

Imagine this scenario:

1. I start Firefox and go to a page that requires a login, so I enter my master password.
2. I leave my computer.
3. Somebody else accesses my computer. They can go to any site they want, since Firefox 'remembers' my master password.

How can I protect myself from this? I can close Firefox, I can log off my computer or I can use a screen-saver password.

I would prefer a solution within Firefox, something like a button (possibly under Application Menu → Passwords) to force the master password to be re-entered the next time it is required.

I do not understand what is the reason I am unable to access my account. I am using the password which I wrote in my password book. What must I do to proceed? Thank you. Your assistance is appreciated by me.
