Firefox Community Forum

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

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)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

Greetings support team. The problem is a bit complicated and I could't find anything similar to it on the net, so I'll try to explain in details what happened. One day after opening the browser I noticed that it didn't launch(there was no window). After opening it again I saw that all of my previously opened tabs were gone. After that I closed Firefox and went to check the task manager. I found that Firefox was still running after closing it. I couldn't wrap my head around it and killed the programm. Then I opened it again and got the same results: first launch: no Firefox window(nothing on the taskbar either), secound launch: one empty tab. After that I opened a new tab in Firefox through task manager and my screen "swiped right", I got access to Firefox window with all of my previous tabs, but all the other programms I had opened on the taskbar were gone. Somehow Firefox opens outside my screen on a "separate one" every first time I launch the app, and the only way to switch between "screens" is to open a new tab through task manager or launch a program that was previously active to switch back to previous "screen". It is also impossible to switch between opened windows on different "screens" using gestures on the touchpad or "Alt" + "Tab". I use a laptop and never even tried to attach/connect a second monitor. I don't have another monitor attached via bluetooth or any other means in device manager. I have the latest verion of windows 10 installed and updated. I have another PC, where I use the same Firefox with the same addons on the same Mozilla account, which has no such issues. I have tried renaming the file called "xulstore.json" to "xulstore.old" or deleting it entirely, this didn't resolve the issue.

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?

How can I find or add the translate icon to the toolbar. I did a screenshot but can't see how to insert it. My tool bar has only a toggle reader icon and a favorites icon after the url in the address bar. translate does seem to work automatically on the first page of website, but then does not work on other tabs of the same website. screen shot added

I just updated to the latest version of Windows 10, and now when using Firefox (126.0), the url dropdown menu rather than dropping down now "floats" over the browser window with the top cut off. The top url is still there, and I can navigate to it using the arrow keys, but it doesn't show. This is new as of this morning, when Windows updated. No issue in other browsers.

Hi,

On several site like this one:

https://www.iqglassuk.com/contact/113/

Clicking on the "I am not a robot" box (no complicated challenge) shows a permanent revolving wheel.

That happens also in safe mode, but not with Chrome.

I am using FF Developer 126.0b8 (64-bit).

Thanks.

When I'm in full screen mode, The Apple, "Firefox" "File" "Edit" "View" "History" "Bookmarks" "Tools" etc menu bar shows up at the top and won't disappear. On my iMac Pro, it doesn't show up. i.e. Off.

I can't figure out what is the setting to make sure it does not appear. I went digging everywhere and can't figure it out. If you could tell me what config, etc I'm missing I'd appreciate it.

Screen shot attached to show which menu bar I mean.

My firefox is up to date: 126.0 (64-bit)

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.

Hi After the latest update, the address bar dissapears everytime I click on it to type in an address. It gets hidden behind previous addresses I visited. Completely unusable. I have no idea why it is so bad and how to fix, please help. Thanks

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.

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.

When visiting the "support.mozilla.org site, third-party translantion add-ons(such as "Immersive Translate") can't work. It says "can not read or change data on this site". I want to translate it on the same page rather than skipping into a new page. However, it can work on the "www.mozilla.org" site. When visiting on Chrome, there is not a problem. Is that site just privileged on Firefox ?

Whenever I try to write anything into the address bar the suggestions cover it completely and I can't see what I am writing, see Picutre1!

However when I launch the browser in troubleshoot mode from the help menu, everything works fine, see Picture2.

The only addon I have installed is Youtube adBlock. There are two plugins running, a codec by sisco systems and a decrypt module by google.

Could somebody help me with this problem?

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?

So i wanted to remove borderline between text bar and tab bar. After some googling i manege to do so by console(contl+shift+alt+i), in string "--tabs-navbar-separator-color: light-dark(rgba(0,0,0,.1), rgba(0,0,0,.3));" i change 3 to 0 and borderline gone. But every time i restart browser is all back. Is there any way to make it permanent ?

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?
