Meschat is displaying blank page in Firefox - firefox

The other day I noticed that Meshcat was no longer displaying in Firefox on Ubuntu 20.04. The server would load, but just display a blank white page. My recent Firefox version is 100.0.2, and it was working fine last week (before the update). Upon inspection, this is the traceback that appears in the console:
THREE.WebGLRenderer: Error creating WebGL context.
Failed to create WebGL context: WebGL creation failed:
* tryNativeGL ()
* Exhausted GL driver options. (FEATURE_FAILURE_WEBGL_EXHAUSTED_DRIVERS)
I have tried changing webgl.force-enabled=true in about:config, but that did not work. I am tagging as drake in case any other firefox users have experienced the same. My only fix for now is switching to Chrome.

Firefox 100.0.2 on Ubuntu 20.04 with Meshcat git sha 65781fc has been working fine for me.
Have you tried rebooting? Sometimes Ubuntu's automatic upgrades cause OpenGL contexts to stop working until after a reboot.

How Can I Fix Glitchy Images on Google Chrome?

I would like to ask about these images I found to be glitchy on google chrome.
I must confirm that none of these are intentional.
This started since I saw a glitchy image on my google classroom, here are some images I found to be glitchy. I don't seems to find a pattern from them.
Glitchy image on google classroom
How the google classroom image should look like (my friend's perspective)
Broken logos of chrome extensions (fullscreen)
Broken search icon
Broken pdf icon on web.whatsapp.com
It sometimes manages to fix itself though, I successfully took a screenshot of glitchy icons and the normal ones.
Search Icons, both normal and glitchy displayed at the same time
I've tried to delete images cache and even reinstalled chrome, none of them works to fix this problem.
Some information that might help narrow down the problem:
I've recently used this PC with a new SSD (I've used it for about a month now), which contains the chrome itself, and it works properly so far. I don't think this should be a problem with the disk. (please correct me if I'm wrong)
However, on the day this happens, I installed the React Devtool (I've deleted it though) (https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi) and the Redux Devtools (https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd)
Can this problem be a bug on the chrome itself, or perhaps something related with skia? Should I report this as a problem to Chrome, or is this a problem on my end?
Information about my OS and Google Chrome (I'll provide more if it is required):
OS:
Edition: Windows 10 Pro
Version: 20H2
Installed on: ‎1/‎10/‎2022
OS build: 19042.1526
Experience: Windows Feature Experience Pack 120.2212.4170.0
Chrome:
Version: 98.0.4758.102 (Official Build) (64-bit)
Thanks
EDIT: Fixed, I changed from using GPU 0 to GPU 1 via settings, is this a graphics card compatibility issue?
GPU 0: Intel(R) HD Graphics 530
GPU 1: NVIDIA GeForce GTX 950M
Setting "Choose ANGLE graphics backend" (chrome flag) to "OpenGL" fixed the issue for me.

Createjs and Firefox 72

After updating Firefox (Firefox 72.0) an error appeared: "The buffer passed to decodeAudioData contains invalid content which cannot be decoded successfully." Apps don't work, because of this problem with audio playback. Has anyone encountered such a problem? Thanks.
Got the exact same problem but here's a bit more info for anyone working on a solution. The latest updates of firefox work fine on IOS and Android, the problem is on windows 10. Here are a couple of educational resources that several of our school's reported as broken by the recent update (they work fine in chrome, safari and edge):

For comparison, here is a rource that still works in Firefox:

All resource were built using the same libraries, notably createJS.

How do I troubleshoot Oculus in Firefox WebVR?

I'm currently using Oculus Rift + Touch in A-Frame (0.6.1). I haven't found any online forum on where to ask. I've tried using Firefox 55 (Which comes with WebVR), but it doesn't detect the Rift.
I can use Firefox Nightly, but it's very unstable, and it comes with different problems. My most recent one, is that the whole screen goes blank whenever I try to enter VR mode. The display is seen in the headset, and the app is able to work flawlessly. But I can't go back to Firefox and check the devtools (which is annoying).
How can I troubleshoot the Oculus Rift so I can connect it to a stable version of Firefox, such as 55?
Tried checking this:
WebVR supported, but no VRDisplays found, suddnly
But it didn't help.
Check about:config in Firefox and make sure the VR flags are enabled (specifically the Oculus one). Sometimes it may be disabled for some reason.

Flash Object slow in IE and Chrome but not in Firefox(WaterFox)

Can someone please shed some light or point me in a different direction.
We are using adobe flash that launches an app inside of a JSP. Up until yesterday everything was running fine without any issues. Today when the Flash Object launches you can see the initialize bar where before you hardly seen it.
While working within the app as well all the operations are very slow (not much but a 2 second delay on most of the things is visible).
I have 3 browsers installed on my PC
IE 11 running Flash version 23.0.0.207
Chrome 55.0.2883.87 running Flash version 24.0.0.194
Waterfox 32.0 also running the same Flash version as IE 23.0.0.207
Running the app from all 3 these browsers is slow apart from Waterfox.
I deleted all the caches from the flash settings in control panel and for chrome I used the web interface (http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html).
I cleared all browser caches. We are running McCafee which I disabled.
I had a look at any windows updates that was done recently which I uninstalled.
What could be different between these? What else can be checked to see what is making this app slow in IE and Chrome?
The slowness could be caused by the files not being cached by the browser like they used to be. I would start there. If you reload the page and you're not seeing a 304 "Not Modified" for the swf(s) you're loading them from the server each time where they used to be loaded from the browsers cache.
Here's some more info on the subject: https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching
Both Chrome and IE have developer tools you can load to see the http calls and check the headers and response codes.

Browser hangs when debugging Flash

Since the latest update to Firefox 3.6.13 I can no longer debug flash apps. If I have the debug flash player installed, it hangs when loading my application, and never connects to the debugger.
I'm running Flash Debug 10.2 (latest one).
I've tried uninstalling / reinstalling, but I get the same experience.
When the page loads, the browser hangs, 10+ seconds later, the page continues. It happens on my application as well as sites like Hulu.
Anyone else have similar issues?
I already disabled the dom.ipc.plugins.enabled.npswf32.dll and set timeoutSecs to -1.
--EDIT--
This issue seems to happen in all browsers (IE, Firefox, Chrome) with Flash Debug player 10.1 or 10.2. I'm not quite sure what the issue might be.
Somehow my hosts entry for "localhost" got mangled when editing the file. This caused the debugger to look for a debug host on another machine. It then waited for the timeout before continuing to work.
Fixing the localhost issue fixed my debugging issue.
