Forum d’assistance Firefox

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.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

My Firefox tab keeps crashing on a particular website. Whenever I go to twitch.tv, the site begins to load and then I get the "Gah. Your tab just crashed." screen. I'm only getting this crash on twitch.tv pages, and this issue just started on May 31, 2024. When I try to open a twitch.tv page in Private Mode, the page loads just fine. I've never had a Firefox tab crash prior to this.

I've tried turning off all of my Firefox extensions, but that didn't solve the issue. I also tried opening Firefox in Troubleshooting Mode, but I still got the tab crash. I'm using the latest version of Firefox as of today's date.

control + UP (arrow) is documented to "go to top of page". That has broken as of 126.0 And, for some reason I don't remember, I found that using "HOME" in the past was also problematic.

How do I report something as "b roken" to firefox and do you agree it is broken?

I had to restore Windows to its initial settings. I lost all my programs because of this, including Firefox. I reinstalled the browser, logged in to my account (which is synchronized), but instead of recovering all my bookmarks I got nothing. Empty bookmark box. What's worse, they were initially available on the mobile device, but they were also deleted there (both from the browser and from the smartphone). Firefox restored history, add-ons, but not bookmarks. Is there any way to recover these bookmarks?

I have just upgraded the OS on Mac Mini with the M1 chip to Sonoma (14.5) I am running Firefox 126.0.

Now it seems that I have more than one problem since the upgrade. The browsing history in my sidebar is not current. It is running about a day behind.

I reported earlier that the type on my LinkedIn is only out 7 pt when my settings have the minimum size at 14 pt.

Somebody please help. I'm afraid to do a refresh because I don't know what it will do to my banking settings.

After up grading to a Mac Studio running Os 14.5, I downloaded the latest Firefox 126.0. I have three other computers with Firefox. The oldest a Mac Pro running 10.13.6 Hi Sierra that works flawlessly. I tried sync and bookmarks came over to the Mac Studio but not any passwords. I tried importing via a .csv file and got the message: Import complete New passwords added: 0 Existing entries updated: 0 Duplicate entries found: 0 Errors 190 (not imported)

Firefox will NOT even save manually entered passwords. I suspect some problem with Sonoma's paranoid security but I cannot find a solution. Any suggestions?

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.

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

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.

Hey,

I have previously exported my bookmarks in an HTML file. When reinstalling Firefox, I tried to import them using the HTML backup file. It says that 309 bookmarks have been found, but nothing changes on the bookmarks bar, still showing the "Import bookmarks" bookmark. These are very important bookmarks I would really like to get back, can you help me please ?

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

I was in the middle of asking this question when I fixed (worked around) the problem so I'm posting more as a informative post as there is a lot of old misdirection out there now.

I am(was) unable to drag any URLs from the URI drop down field in the main interface to my bookmarks toolbar. Nor was any drag and drop functionality working in the "Customise Firefox" screen (right click space on url bar -> Customise Toolbar).

I have now found that resetting my zoom setting in preferences to 100% restores this functionality. The problem arose when I was using 120% zoom, NOT text only.

After applied Chinese Language Pack, the menu didn't change ,even after restart firefox or the system. I tried refresh firefox and re-install the language pack, the same situation appeared.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

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.

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?

Since 2 weeks, I have been facing a UI error in the address bar. Whenever I select it to type something, the bar and search suggestions jump up off-screen. Pic attached.

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!

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...
