Firefox Community Forum

A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

Hello,

I recently deleted pwnedpasswords.com from my cookies, as well as blocked this website; however, it keeps reappearing in my list of cookies.

I've never even visited this site (that I'm aware of), and it's a bit concerning to me.

In spite of clearing ALL my cookies (and blocking this website), it keeps appearing in my list!

Please advise :)

Full scenario: Computer had some issues, so I set up Windows Backup/Restore to a point just before resetting it, saving that data to an external drive. Then, I reset Windows, choosing the option that lets you keep your files (most of them it looks like) while it reinstalls everything else.

I knew it'd wipe Firefox and I'd need to reinstall it, but when I synced my account, it didn't have logs. The logs are archives of various chats on a website I used to talk to friends. I know those used to be accessible through Firefox's directory under Program Files by checking the data saved for that website (something I had to do once before to remove corrupted logs), but that data obviously wouldn't be there now.

I should've considered this beforehand but I had no idea that data for different websites might not be included in a sync. It does have files for Firefox but I decided not to touch them, since I'd already synced and I didn't know if reverting to that Backup might break Firefox somehow. Or worse, cause me to lose MORE data.

Question now is, what's the chance those might be in that backup I saved? More specifically, data stored about websites I visited.

Hello, I made animations CSS on my web site and everything was working great on all browsers. I just see that it doesn't work anymore only in firefox...

Thanks a lot for your help!!

Hey there, long story short - nowadays it's crucial to support those who WFH, and most people use G Suit for company work. I personally have a few daily calls via Google Meet and having the TAB sharing feature available is highly appreciated. I know this was requested a lot, but this is a real dealbreaker for many people.

What are your thoughts on this? Maybe it's somewhere in the roadmap already? Thanks!

I have been trying to solve this for a few days now. I tried to watch Netflix when it said, "Firefox is installing components needed to play the audio or video on this page. Please try again later."

I found out this was due to Widevine not being installed AT ALL on my browser for some reason. The plugins manager has been saying that it will "be installed shortly" for a week now. I already tried toggling DRM off and on multiple times. I already tried using troubleshooting mode. I already checked GMP preferences to make sure nothing relating to Widevine was set to 'false'. I already tried turning off my antivirus long enough to try everything again and still nothing has changed. I do not have any VPNs running either. I am attaching a screenshot of what the browser console shows when I toggle DRM off and on again and try to run Netflix. I am also attaching what the gmp toggles say. Please help me figure out what is wrong!

Just checking, can I still make a $3 monthly Paypal donation to Mozilla, or is that amount too small, or does it expire, or something to that effect? Thanks much!

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

There is a display issue when I search anything in the url bar. It goes up the window, and disappears completely if many suggestions are made. The issue disappears when in troubleshooting mode. I disabled all plugins, changed the theme to no avail.

I'm trying to use the built-in PDF Editor features after finding out about it but every PDF file I open with Firefox has the options grayed out (as shown in the screenshot). What should I do to re-enable the features?

Hello,

I cannot open the uwyo.edu website on my Firefox browser. I have no problems with other browsers. I tried and checked the solutions people shared, but none of them worked for me. I checked the DNS and different networks, and I also checked the link below:

https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can

I would appreciate it if you could help.

Thank you and best regards, Farshad

Concurrent with updating to Firefox 126.0, when typing into the address bar, the list of suggested sites covers-up the address bar. In fact, the top of the list is off the screen. I don't see any other posts relative to this, am I the only one with this problem... and how do I fix it?

Hello, Since a couple of weeks I'm facing a strange issue on my Firefox installed on my desktop (arch linux) where the suggestions window that appears when clicking the URL address bar, is shifted upwards and covers the address bar itself and the majority of the bookmarks. Has anyone experienced a similar issue and is able to point me towards some troubleshooting steps? Thanks!

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

Hi, it seems that my Firefox browser does not want to save a new payment method. I'm trying to access "Settings -> Privacy & Security -> Autofill" and then click on "Saved payment methods", which opens a dialog with the existing payment methods and options to remove/add/edit. I'm clicking on Add, filling-in the card details and then clicking Save, nothing happens....

I previously had a working saved payment method, but it stopped working (I think more than 6 months ago). I tried to re-enable the credit cards by setting the following configs on about:config page:

- extensions.formautofill.creditCards.available: true
- extensions.formautofill.creditCards.supportedCountries: '...,RO' -> (I was adding my country to the existing list)

After the browser restart with those new settings when I'm on a payment page, clicking on a credit card field will show the saved credit card but if I click on it, it will not fill the details. And also trying to save a new card, manually as described previously in this message, or by the automatically prompt to save a new card after a successful payment was done. Both methods failed on me but with no error (I cannot see the saved payment on the list).

I tried removing the existing saved card, it worked removing it, but the add is still not working.

I also tried restarting in save mode, launching Firefox in a separate profile and added my country on the creditCards config for supportedCountries to show the "Saved payment methods" button on new profile, and it did not change anything.

I'm thinking there is a missing permission somewhere on the disk but I don't know where is the payment data stored on disk.

I would really appreciate any help on this.

PS: Check the attached pic to see the payment add and clicking the save button does nothing (also there are no validation errors). And the other: FF version, OS, troubleshooting info.

For some reason, recent updates caused my Firefox address bar to misbehave.

I have already murdered the unwanted search engine suggestions which the standard settings failed to kill - I just kept turning things off in about:settings until the garbage feature died.

However, I am still unable to address the most annoying bug.

When I start typing in address bar, the pop-up box with suggestions, rather than attach itself to the bottom of the address bar, goes to some imagined, predefined anchor point which is off screen, somewhere outside the confines of the window. As a result, I see some suggestions, but I no longer see what the hell I'm even typing. I am attaching a screenshot. This is super annoying, as I am literally forced to either use bookmarks, or type out urls in notepad then paste them over.

Anyone can help?

On nytimes.com some page elements are missing like pictures. the onepiecedle page just displays the background.

In Pic1 you can see what the page is supposed to look like, here opened in chrome

In Pic 2 you can see what it looks like in Firefox 126

I tested troubleshoot mode, private window, etp off, private window, hardware accel. on/off, nothing seems to work.

Since the latest update, when I right-click on a bookmark or an item in the history list (from the menu or the bookmarks toolbar), I still get the menu that has items like "Open in new tab" or "Edit Bookmark".

However, the focus for the mouse stays on the previous menu, so that I can't click on anything in the "right-click menu", instead it is interpreted as a click in some random item in the previous menu.

Going into troubleshoot mode didn't help, so I don't think it's my configuration causing this.

It seems firefox has changed the behavior of tabs. When I go to open a closed tab, I see a list of all the tabs that have been closed from every window. I want to restore the previous behavior where "recently closed tabs" only shows the tabs that were closed in the current window. I saw some about:config settings, but I'm not sure what they do and I don't want to end up losing the tab history all together.

Thanks
