After connecting a bluetooth headset and using Firefox (115.0a1 (Build #2015950435), 1d9511bcc3 + this version so far) to play online video is obviously lagging, not audio and video is not synchronized, is to play a moment to get stuck in a frame like this. My own troubleshooting revealed a problem with Firefox and the encoding format selected for the headset. Currently 1 the problem is only in bluetooth audio encoder selection acc (lhdc also have the problem but the symptoms are not as serious as aac) and triggered in firefox, other browsers can not be reproduced, test redmi k40 and xiaomi 13p also can not be reproduced. 2 after the screen recording is turned on, the problem is obviously lagging. 2 The problem disappeared after turning on screen recording, the screen recording parameter is 1280x720@60 at 32mbps, and the audio source is recorded in the system. Play the video first and then open the screen recording lag disappeared, first start screen recording after playing the video lag does not appear. And no matter what kind of situation screen recording stops lag recovery.

Steps: - create an iframe without src - create click event listener on any other element - set iframe src to on click to some url that supports "go to application" e.g. YouTube embed url

Expected: Iframe shows youtube video on element click

Actual: Firefox asks to open a new tab or open an app, and never shows this in iframe

Fix for developers: Recreate the iframe with the src

It only works on ff android, we spent literally hours to catch this bug

This situation happened after I updated to the latest version of Firefox at Play Store. Once I connect to the VPN, every website only shows this error and refuse to open normally. After I uninstalled and reinstalled it, nothing changed even I also cleared the cookies and cache. And then I downloaded the extension called FoxyProxy and selected it's proxy type as system, but it showed that system settings is not supported due to Firefox limitation.

I didn't change anything, a few days ago everything went well, but it just happened suddenly without any notice. Other browsers are fine except Firefox.

Please advise. Thanks for your assistance.

NUMEROUS websites respond that I need to enable JavaScript when I'm using Firefox bruiser on both my phone and in my Mac. How do I do this?

There have been numerous requests for this information and it's never been answered!

Help!

Thanks!

I'm a regular user of community.signalusers.org, which is a community forum for users of the Signal messaging platform. The website uses the open-source Discourse application to host the community forum.

Often, however, Firefox fails to load the website. The webpage begins to load, but doesn't move beyond the page you see in the screenshot.

I suspect this has to do with Discourse because another website that uses it (0x00sec.org) also doesn't load.

Both these websites load just fine on Google Chrome. I have attached Screenshots of both. Not sure if there any debug logs or such that I can attach that might be useful here.

I'm accessing the websites from a OnePlus 6T running Android 11. I'm running the latest Firefox beta. This issue is also not 100% reproducible, unfortunately, so it's that much more annoying. It occurs seemingly randomly, and then seems to fix itself at some point, only to break again.

Happy to provide more info, if needed.

[With ~Ff 123?8 and now 124 installed on iOS 17.3 platform updated a couple weeks ago from iOS 15.+ on my iPhone XR]

  For couple weeks , following any external link/reference, such as all 'unsubscribe' links from Apple Mail messages, Firefox opens but homepage rather than to the link/url argument (and url field shows blank, not display the extrrnal link's url address in url input box.
  Support history shows an identical problem in Ff ~117 reported (Aug '23, I think)   (if the condition of Firefox not currently running is same, which I haven't yet been able to determine) and apparently resolved then ( 2 replies, but thread is not visible because FF Support has it recorded as "Archived").

I'm following the instructions to set Firefox nightly as my default browser, but when I go to settings and try to switch the toggle to "set as default browser" instead of doing it, it just opens a new tab with the instruction. I got up to 4 identical tabs before I gave up. I know how to do it, it's just malfunctioning.

In a separate issue, I have had Firefox Beta for about a year on my Kindle Fire, always worked great. Since the latest update, it won't even open. The screen pops up for a second, then immediately closes. I uninstalled and reinstalled, same issue. I installed regular Firefox, no issue. Then I found nightly, installed with no issue (other than the problem listed above).

For the last two months I am unable to use a Classmates.com webpage that I have been using for 15 years. It suddenly keeps giving me the following error message Secure Connection Failed

An error occurred during a connection to www.classcreator.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

I have contacted the company and they keep telling me it's my connection or browser and they can't help me. I know there is probably one setting that somehow is wrong but I can't get anyone to figure it out for me. I have tried everything possible. Can this be a browser setting that will not let me edit anything on this webpage? I can edit on other pages that are basically the same type of program ( reunions for schools) PLEASE HELP. YES, MY SECURITY CERTIFICATE IS PAID UP AND ACTIVE.

The soft touch(or short touch?) feature on the website doesn't seem to work on Firefox. Compared to chrome, Samsung Internet, Brave, Vivaldi

In other browsers, if you lightly touch a post on a community site, etc., the post will highlight or display a preview image, but Firefox does not show this feature, only displays a system window, such as copying links, when pressed strongly.

This problem seems to be related to the browser's touch function. It's not a long press. It's a matter of short press

When not in fullscreen, visualViewport updates correctly. However in fullscreen mode visualViewport remains fixed and never changes. Is this a bug? It's creating an issue for my webapp which has a fixed text entry element at the bottom of the fullscreen element. I have to detect the visualviewport changing when the keyboard shows otherwise it is completely obscured. Please assist me.

While browsing Amazon.com using the past several builds of the Nightly for Android, I get this most annoying bouncing pop-up tip that is a yellowish with black font saying to click on this heart icon to save the product. I have never seen this on any other browser for Android, and never on my Firefox on my laptop or desktop. Is there anyway to get rid of it? I cannot stand this and I have almost thrown my phone because of it many times. I have never thrown a phone before. I cannot explain why, but it pisses me off so very much!

Not sure WHY but suddenly I cannot open links or ages on my Android phone. It seems that JavaScript has gone missing and I have spent two entire days trying to get it back with about:config but it's not allowing me to proceed and it's a major pain I need to fix ASAP.

Install often does not work nearly as well as the web page. For example, spelling bee "installed" on my Samsung tab A7, has difficulty accepting taps. Only about 1 in 3 taps will register a letter. On my brand new Pixel 7A, the spelling bee app is not in dark mode, even though it is in the browser. And my entire phone is dark mode. Also, I can't click on the share or overflow menus. Installing the New York times games page has the same problems. And last, on my pixel 7a, the USGS earthquakes app jumps around all over the place making it useless. It would be nice to have both options, "install" and "add to home screen" in case the install fails.

Hello *,

i use Firebox on my Huawei Y6s and have oermanen problems withvlogin and captchas, because they claim, I have Firefox 25 installed

My version is

119.0b3 (Build #2015977017), c6de0a34a8+ GV: 119.0-20230929091427 AS: 119.0

And was only update 3 days ago.

Note: i have no Addons installed and about:config does not work here.

How can this be solved?

Thankyou

I raised this issue in my review on the Google App Store and was asked to submit it as a question here. On my phone (Oppo running on ColorOS 13.1), Firefox will stop working a number of times a month. For about 24 hours, aside from Google result pages, nothing will load, and I'll be stuck looking at an empty loading screen. The last time I raised this issue I was told to delete and reinstall the app, which worked in the moment but did nothing to stop the problem occurring again. Aside from waiting for the app to fix itself, nothing I've found works.

Firefox for iOS no longer will open when I click from my mail or the QR scanner. This is a recent development. To be precise, Firefox opens, but nothing else happens! Any suggestions? Thanks.
