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

Since an update from a few days ago (May 2024), my address bar/search bar is now basically outside of my PC screen, see here: https://vimeo.com/948314161

It's not a local problem, it's also happening on other PCs/Laptops I have.

How can I fix this? PS should the answer be that I need an add-on or anything like that, then it's bye bye Firefox, hello Chrome

Thank you

Hello, I have a weird bug with the firefox browser causing weird graphical glitches only on the main screen when a HDMI cable is plugged in on the duplicate mode. I have found that is is only on firefox and not my desktop or any other programs. Firefox is up to date and the issue is fixed when the HDMI set to extend

I hope you find out why this is happening and fix it swiftly Thank you -Dominic

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Sadly, I am now forced to leave firefox. My passwords are getting "forgotten" more and more each day. Did i get hacked? Few passwords like proton mail I don't actually have anywhere else. Auto-Backup of firefox seems to be of the same day as the original??? So it loses the data then saves it twice? who designed this? I'm angry, not at firefox/mozilla. angry at myself for putting my trust in the first place. Chromium doesn't sync so it leaves me with chrome FFS. Does someone has a magic wand to recover the lost data? login.json is same day as original so not an option.

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.

I recently came across a webpage that is made to look like a message from Firefox letting you know you need to update the browser. Where should this be reported? I'm sure this is some malicious download though I have no way of checking.

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?

Firefox is synced on all my computers. Same version. Same extensions. I can't login on my primary desktop as of last night 5/23/24. I can login/watch Prime on my laptop. My desktop gives me the attached error.

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

Hello, I closed my browser, expecting it to save my current tabs as it usually does. When I reopened it, the tabs were gone. They were important for me, and some of them were pretty old so I can't find them in my history. I tried checking the "recently closed tabs" option, it didn't help. There was also no option to restore the previous session. Can you help me restore my lost tabs?

Ridiculous with the new update page saying " A browser that's truly yours My Firefox: More Speed, More Security, More Fun." WHEN YOU CANNOT TURN OFF THE IDIOTIC popup spam for the updates NOT EVEN GOOGLE CHROME DOES THAT. And ridiculous it has to LOAD THE UPDATE after restarting the browser lag time and IDIOTIC BRIGHT SCREEN FLASHING even if you have darkmode on, JESUS CHRIST this browser seems ridiculous and FAR WORSE THAN THE OTHERS WHEN EVEN CHROME IS BETTER with these settings and not being pointlessly ridiculous rofl. WHAT is going on with that people. AND SETTINGS TO FIX THAT would make this less ridiculous to use obviously, THANK

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.

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Just today, I can no longer access the Amazon website. The pages load halfway and then it just churns/spins and never completes loading the page. So far I've discovered no other websites that have the same problem.

I am able to access the Amazon website on three other browsers - Edge, Brave and DuckDuckGo - with no problems and normal loading speed. I don't use Chrome, so I can't speak to that.

I've tried clearing the cache and that did not help. I had a Firefox update installed a couple of days ago. Don't know how long it had been sitting there, as Firefox is almost always open and doesn't have the opportunity to update until I close everything and restart my computer, which I did a couple of days ago.

Windows 10 on a Dell pc/laptop. Firefox Version 126.0 (64-bit).

Any ideas on how to fix?
