When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?

I have a well hidden web server that uses HTTP. I need to download files from that server. After the newest update, Firefox now gives a warning about the website and on that warning is a button to "Allow Download". However when I click on that button, the file that gets downloaded IS NOT the file that I was initially attempting to download. It looks like it is a copy of the web page that was being displayed at the time. I noticed this behavior at work. I went home and used Firefox to connect to the server and everything connected and downloaded correctly. I went to see what version of Firefox was running. It was 124.0.2 and there was a button saying "Update Firefox". I clicked that button. My home Firefox updated to 125.01 and my home version of Firefox now also downloads the wrong file.

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 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:

How can I get Firefox to display the background colors?

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.

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.

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

Hi,

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

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.

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

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

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?

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?

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

Hi there, my name is Alvimutmex. Every time a webpage loads with the Mozilla browser, a "not supported" message appears. Upon examining the settings, I found that Mozilla has to be updated. Would you kindly assist me with updating Mozilla? For example, I receive an error notification when I try to open (https://pdfmedicalbooks.com/).

We have an intranet site behind an Active Directory Federation Services (AD FS) - after updating the SSL certificate, the website will no longer allow Firefox clients to log in.

They will be prompted to sign in (with a default sign in prompt, not even the website login prompt), even if you enter the correct user/password it will continue to prompt you. The new cert works with Edge, Safari, and Chrome - I've enabled the following settings in about:Config network.automatic-ntlm-auth.trusted-uris, network.negotiate-auth.delegation-uris, network.negotiate-auth.trusted-uris, and set signon.autologin.proxy to be true - but the issue still persists.

Has anyone seen this/been able to figure this out? I've seen a few other posts, but no resolutions. Does Firefox not support Certificate Signature Algorithm SHA-384 With RSA Encryption? This is the only difference I can see between the 2 certificates; the original is SHA-256 With RSA Encryption.

Thank you!
