Firefox Support Forum

I have a problem where if I install the packages needed to get hardware video decoding working in firefox it completely breaks YouTube playback. I can't find any info on the internet about the problem and I am having a lot of trouble with it. YouTube playback with libva-mesa-driver and libva-vdpau-driver will start stop restart start playing audio then crash with a this error every single time. I am at my wits end trying to figure out this problem and I would love help figuring out the problem I am using firefox-developer-edition as a note thanks Ozzy

The 125.0.2 update broke Amazon Prime Video. Firefox refuses to play ANY video, causes website to return a "That shouldn't have happened" error page. Prime Video plays just fine on Safari 16.6.1, macOS 11.7.10. Amazon says just to use Safari, but I want Firefox to work right.

A few weeks ago I began, while trying to connect to Kaiser from an email message, to get a response that said it was unable to connect because "server not able to redirect." I wasn't getting any error messages from any other sites or attempts to connect with any other sites.

I contacted Kaiser and got some tech office in California (I'm in Hawaii). I did all that they suggested, i.e. "cleaning up" my computer, and I even paid and installed a program called "CClean", and used "Ninite." After making all the "clean ups" the error message was still happening, and later it even mentioned Firefox in the message.

At that point I had no idea what to do and went to "help" on the application menu. Did the "troubleshooting" a couple times, and then saw a "refresh" button, that I thought was probably, and looked innocuous; this led to a bunch of other things that I certainly didn't want to mistakenly perform anything untoward.

After all this I was finally able to link properly with Kaiser, BUT ALL OF MY TABS WERE GONE!

This seems to be a real problem on Firefox, since I've NEVER seen anything that is easy to select to "resolve", "reinstate", or "RECOVER" tabs. I've seen many of the same questions about TAB recovery before.

I've been with Firefox for probably a couple of decades now, and this seems to be a major issue without any "easy" solution. Or, am I just missing something completely?!

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

Hey all, as of the past few days when I get the prompt to enter my password on Outlook.com (And microsoft.com) and hit 'sign in' the page just reloads and nothing happens. There is no failed login message, the page just reloads like I didn't hit sign in. I have disabled all of my extensions, cleared cookies and cache, ETP... with no luck.

Works fine on Chrome for android...

I'd really like to stay with Firefox so all help seriously appreciated

Greetings, I am Alvimutmex. A "not supported" notice shows up each time the Mozilla browser loads a webpage. After looking through the settings, I discovered that Mozilla has to be updated. Could you please help me update Mozilla? For instance, when I attempt to open (https://phoneinsurance.us/), I get an error warning.

I was using Amazon just fine a few days ago. When I tried to open an amazon link yesterday, I got the message: Secure Connection Failed. I tried updating my browser and clearing my cache and cookies. Please fix

Website is being set to reject Firefox browser only, asks me to use alternative, why?

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?

I am attempting to report that Yahoo Finance is broken. From this URL, I use the "report broken site" feature:

https://finance.yahoo.com/quote/DEO/

When I fill out the information and hit "send", nothing happens. The "report broken site" screen remains active. Hitting Send multiple times has no effect.

I've tried using this feature for other pages, and it appears to work; but it won't work for this site.

Can anyone suggest why that might be? Is it a byproduct of the site's being broken?

Thanks.

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

Hi,

The website below is not opening in Firefox but in Chrome. What setting is missing in Firefox? https://de.yvesdelorme.com/

I'm having trouble with Firefox where images aren't loading on some websites, even though they display fine in other browsers. I've tried clearing the cache and restarting Firefox, but the issue persists.

Is there anything else I can try to fix this problem and get images to load properly?

Hello,

I have encountered a recurring issue specifically with Firefox where SVG images fail to display unless a pixel-defined height attribute is explicitly set. This behavior contrasts with other browsers, which handle SVG scaling seamlessly, typically adapting to the specified width or inheriting dimensions from parent elements.

During our website development, primarily through Elementor and leveraging Flexbox in a WordPress environment, this discrepancy becomes evident. The issue persists exclusively in Firefox, confirmed through extensive testing across various browsers and OS's with multiple SVG files and sites.

For diagnostic purposes, I recommend conducting controlled tests with SVG images embedded with our current setup. Set the SVGs to 100% width without defining their height and observe how they render in Firefox compared to other browsers. This should help ascertain whether the behavior in Firefox is anomalous.

I am assuming it may be with the way the markup of the SVG is rendered as it doesn't happen with all SVGs, however, other browsers appear to fix or override whatever is getting in the way from rendering...it is a strange issue.

I have included two images as an example. As you can see in the first image, the SVG isn't rendering (in Firefox) , but does render in Chrome/Safari. It only works when I define a height in px value on Firefox.

Please let me know if further information is required or if any specific steps need to be undertaken to address this issue.

Thank you.
