Why is Firefox refusing to display Instagram videos?

Windows 7 Home Firefox 115.12.0esr (64-bit) Some Instagram videos play, most don't. E.g. https://www.instagram.com/reel/C8FM6cbOG7v/?mc_cid=e24e48195f

For a fraction of a second, the video shows what appears to be the initial display frame, then goes black. Audio plays. Displays OK on Chrome and Edge.

I've explored the following: Autoplay is allowed Turn off tracking protection Clear cache Clear cookies Digital Rights Management (DRM) is allowed Running in trouble shoot mode, i.e. no extensions Popups not blocked I do not have file user.js I tried hiding prefs.js. Hardware acceleration either on or off: no display

Is there a setting that tells Firefox to report why it makes its choices?

Websites look extremely ugly because of the white borders surrounding icons. I've tried using CSS code I found on Reddit from posts that - I think - are related to my issue, but they proved fruitless.

What CSS/Setting do I have to disable to get rid of this?

Did FireFox just officially do an Enhancer for YouTube...I got this on my Firefox screen. List 'what's new' and asks for donation...don't mind donating but is this a scam message or is it from FireFox?

I recently updated many drivers on my Windows PC as it was running very sluggish. I ran CC cleaner on it and updated 6 drivers including the Graphics card and several others.

Now Firefox browser will not launch. I have installed the latest version of Firefox also.. 127 I believe it is.

Any ideas on how to get it to run again?

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

I want to install the older version of Mozilla firefox for windows 11 in Spanish and Dutch language, please provide the link for Spanish and Dutch for ex. 125 version of Mozilla Firefoz

I had to swap out my hard drive the other day without being able to save any data from Firefox. When the new disk was reloaded from the old one the user names were not made the same as with the old disk. When i use Firefox and save a password it says it has been saved but when I use the same site again the passwords don't fill in. When I look at the passwords via the passwords settings there is nothing there. Can you tell me how to get passwords to work please? Thanks John

I am experiencing a significant issue with my website, which fails to load when accessed via Google Chrome. The website works perfectly on other browsers like chrome, Safari, and Edge.However, when attempting to Click here] in mozila, the page remains blank and does not load at all. Additionally, I have noticed a persistent problem with reCAPTCHA. Even though I solve the CAPTCHA correctly, it repeatedly appears, preventing me from accessing the site. Details: Issue: Website not loading in Mozila firfox Browsers Tested: Chrome, Safari, Edge (All working fine)

Version: [26.0.6478.61/.62]

Operating System: [Windows 10] Additional Issue: reCAPTCHA keeps reappearing despite being solved correctly I have attempted the following troubleshooting steps without success: Clearing browser cache and cookies. Disabling all extensions. Checking the website on incognito mode. Ensuring Mozila is updated to the latest version. I would greatly appreciate any insights or suggestions on how to resolve these issues. Thank you in advance for your assistance! Best regards,

Hello Mozilla community,

I'm encountering a perplexing issue with Mozilla Firefox that I hope someone here can shed some light on. Whenever I set Mozilla Firefox as my default browser, I experience difficulties accessing my website. The site continuously buffers but never fully loads, leaving me unable to view its content.

However, when I switch to a different browser as my default, such as Google Chrome or Microsoft Edge, the website loads without any issues moreover my website is related to Picoworker which runs smoothly on other browsers (Screenshot is also attached). This leads me to believe that the problem might be specific to Mozilla Firefox.

I've tried troubleshooting by clearing the browser cache, disabling extensions, and even reinstalling Firefox, but the problem persists. I've also checked for any errors in the browser console, but nothing seems out of the ordinary.

Could there be any compatibility issues between my website and Mozilla Firefox that are causing this problem? Or is there something else I should investigate to resolve this issue?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

I've recently had trouble logging in to some websites but not others, most recent example is Bandcamp. My login credentials are correct and work on mobile and other browsers. I have tried deleting my cache and cookies to no improvement.

As of 2024 06 20 there are many websites that I cannot login anymore one being Facebook with this message:Update Your Browser You’re using a web browser that isn’t supported by Facebook.

Cześć Mój problem polega na tym że na niektórych stronach zniekształca wyrazy ja w załączonym przykładzie. Ustawione mam domyślnie na stronach "PL". najczęściej problem jest obserwowany na multikino.pl; mybenefit; gov.pl. było czyszczone cooke i historia nażędziami z przeglądarki i cccliner - nie pomogły. W Chrome nie ma tego problemu. z góry dzięki za pomysły i poświęcony czas ps problem prawdopodobnie pojawił się od chwili kiedy odwiedziłem stronę z narzędziami z Ukrainy - https://www.cooltools.pl/

I'm a long-time Firefox user (I probably came here straight from Netscape!) but lately, I'm starting to see tons of issues, often after every update.

Things that might help: 1. I'm mostly a Windows user, although I have a Mac. I have a LOT of Windows boxes (don't ask) - a couple of work laptops, some private laptops, a couple of micro-desktops that are connected to TVs and so on. This might be relevant, because they're all synced.

2. My profile is pretty old - over 10 years.

3. I've entirely disabled any ad-blockers or add-ons.

So issues happening on multiple machines in the last 24 hours: eBay. Over the last few days, when logging into eBay, if I do a search, I can't change any of the filters along the top Condition, Location, Sort: Best Match etc. I can click on them, but nothing happens.

GoFundMe. I tried to donate tonight and when it toddled off to Paypal, it came up with some kind of Localhost error after I clicked on Submit. Did it on Chrome, and it worked perfectly. Fortunately, the money didn't come out multiple times.

Oracle E-business. I'm sure many of you use this at work. I genuinely can't login to this using Firefox unless I use a private window. I've cleared my ENTIRE cache. Even went into the Folder and manually cleared it all out. If I try and login without being in a private window, I get "Your session is no longer valid or your logon information could not be reestablished from your session."

This is all since the last update to 127.0

My Firefox browser kept freezing up and acting very slow so I closed it. When I reopened it all my tabs did not repopulate like normal. None of them. I have the box checked to reopen all tabs on restart and it has always worked, not this time. Why! How can I get them back. Thanks, Aldo

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

Similar to this problem: https://support.mozilla.org/en-US/questions/1360287 .

I am using Debian 12, i3wm, and Firefox 127.0.1

After adding a new credit card to Firefox, I can go to any website that needs credit card info and it will auto fill successfully. When I reboot my computer and then try to auto fill credit card info, Firefox prompts me for the password to the "Default" keyring, but it does not autofill (something in the input box flashes quickly then it goes blank again). Firefox will not autofill again until I add a new credit card.

I had no success with Firefox in Troubleshooting mode either.

I entered my Mozilla password in Firefox after signing into a Barnard College / Columbia University library computer. I do this several times a week. This time there was a new problem, which I think is a bug.

After I entered my password, I was asked for Duo verification. I made a mistake and entered the verification code for a different app. I was told to try again. I entered the correct code and got an error message that I had tried too many times and to try again later.

I made one mistake. On my second attempt I entered the right code. How is that "too many" times?

Question: Columbia and Barnard send a message for Duo approval when signing into their computers. I think that's easier. Can Mozilla and Firefox be set up that way?

thank you
