Can't pinpoint the date, but a while back Youtube won't play videos anymore. It just shows a black screen in the player. Not even the player UI (pause button, volume, settings menu) shows. Just a black portion of the screen. Now when I went in to get a screenshot, it doesn't even show the black box.

When I play any video on https://www.bilibili.com/ this chinese website After finish the video,The Firefox get white screen and crash And this happen every single time, There is nothing I can do The crash log is here: bp-c489f92a-e918-43ba-ab0b-589210240812

When I copy something to my clipboard I can paste it into Firefox. Into web pages and also into the URL bar.

But when I copy something in Firefox, it does not go to the clipboard. The clipboard still hast the content which was already there.

Also strange: When I cut text in a textarea, input element or the URL bar, the text is removed. But it is not sent to the clipboard. When I cut and paste, the text I get is what was previously in the clipboard.

What could be the cause? How can I debug this problem?

Got the following Error message today after update downloaded. "Error:Platform version '129.0.1 is not compatible with minVersion >= 129.0 maxVersion <= 129.0

PROBLEM: After a restart of Windows 10 and re-starting Firefox, a Firefox window with a YouTube web page in a tab will start playing unbidden. When multiple Firefox windows with multiple tabs each are in use multiple YouTube videos will start playing. (Only one of possibly multiple YouTube tabs per FireFox window, I believe.) The cacaphony is annoying. Tracking down the offending tabs is difficult. (There is no "Show tabs playing media" feature in Firefox.)

QUESTIONS: (1) How do I prevent Firefox from playing media (YouTube and others) unbidden when Firefox re-starts and re-loads its tabs? (2) How do I quickly find which Firefox windows have a tab that is playing media? (3) How do I quickly find which Firefox tabs are playing media? (4) How can YouTube videos be prevented from automatically starting when a Firefox web page with that video is re-loaded?

Hi, Hopefully someone can help. This started a couple of days ago. I'm actually trying to log in to my own account on Flickr. If I just input Flickr.com, the main front page loads, if I then go to log in, I get: "429 Too Many Requests You have sent too many requests in a given amount of time" on the screen. I've only hit enter once. As far as I can see this is the only site that does this BUT Youtube sometimes plays up, so maybe something is happening in the back ground with that. Might be totally unconnected.

I've tried using Opera (my main back up) and that loads my account just fine. I've tried turning off the extensions Adblock, No Script etc and the 429 error still pops up everytime I go to log in..

Any ideas? Anyone?

Thanks in advance. Graham

I am looking into an issue for someone that is using private browsing and to use a financial app. He has the website in the exception list for pop-ups but every time he opens this app in private browsing it asks for him to allow pop ups. When he added the exception he was in non private browsing mode.

My question is, even with the link to this site added to the exception list, is it completely normal for pop-ups to be blocked every time you open private browsing to the same website?

Hi everyone,

I am trying to view streaming live broadcasts in my country's public TV but the site detected some HDCP issue and asked me to use a HDCP-certified HDMI cable. Here is some quick info and what I had tried:

+ Besides privacy reasons, I am unable to share the website address, as viewing is limited to my country's IP addresses by the national broadcaster. + I have a dual-monitor set up to a Windows and a MacOS machine, both installed with Firefox 129.0.2 with add-ons being synced. + Viewing live videos on the same website in Windows Firefox (HDCP-certified cable) has no issue but not on MacOS Firefox (same HDCP-certified cable but different HDMI port on the monitor). + Switching around the different HDMI ports and cables yield the same outcome. + No issue on either Windows or MacOS when viewing recorded videos though. Only live streaming on MacOS is affected. + Tried disabling all add-ons and toggling DRM but to no avail. + Checked Widevine is latest version (4.10.2710.0).

Appreciate any advice or help please. Thanks in advance.

Version 128.0.3 (64-bit) What’s new Mozilla Firefox for Linux Mint

When I visit a page which contains a Google Doc spreadsheet or try to open a Google Spreadsheet the page often fails to render properly and what I see is my desktop background instead of the Google doc element or Google doc sheet. Please see attached. This has been happening for ages and I resorted back to Chrome for such pages but now I'd like to see if it can be resolved.

I've been trying to watch live sports events on SECN+ through my Hulu subscription, but I'm encountering an error message stating, "The media could not be loaded, either because the server or network failed or because the format is not supported." I discovered that Firefox is blocking the stream, while it works perfectly on Chrome. With the college football season and other sports events approaching, I’m concerned that if this issue persists, I may have to stop using Firefox, which I've relied on for over two decades. Please help me fix this issue at your earliest convenience. Thanks.

I’m encountering a persistent issue while browsing certain websites in Firefox where I consistently receive a 'Secure Connection Failed' error message. This issue disrupts my browsing experience and I’m keen to understand how I can troubleshoot and resolve this error effectively.

I’ve already checked my internet connection and confirmed that other browsers do not encounter the same issue. Additionally, I’ve ensured that my system’s date and time settings are accurate. Despite these steps, the problem persists specifically within Firefox.

Could someone please provide detailed steps or insights on how to diagnose and fix the 'Secure Connection Failed' error? I’m particularly interested in understanding how Firefox handles SSL/TLS connections and any specific settings or configurations within Firefox that could affect this error.

Your assistance in resolving this matter would be greatly appreciated. Thank you!

I was working on strengthening my passwords using firefox as my browser and roboform. I had a us bank site open also at the time. I did not change that user id or password. However, ever since then I am unable to sign in to my us bank site. It brings up the site but as soon as I click to sign in, it greys the screen. I am able to sign in to every other site I have tried on the firefox browser. I am also able to sign in to my us bank site on at least two other browsers without issue. What has happened and how can I fix firefox to allow me to use it? The us bank site is not an app. Thank you.

Today, it started.

When I open sites that I am subscribed to, a small gray-shaded nearly transparent rectangular window appears in the upper right of the screen (see attached screen capture), and it blocks access to login and search, thus rendering the site inoperable. The latest site rendered inoperable is Amazon shopping, so this is not a minor thing. I can no longer retain Firefox as my default browser.

No other browser on my Mac does this; the earlier version of Firefox active last night did not do so either. What is the purpose of this gray-shaded window? It makes the latest browser appear to be infected with malware.

I am having trouble pinning any Extensions to my toolbar. When i click on the Extensions icon (puzzle piece), the Extensions menu immediately pops up. My extension (Bitwarden) is set to "Enabled". When I click on the three horizontal dots, however, the only options are 1) Remove, 2) Report, or 3) Manage. There's no option given to pin the extension.

Because of that, the extension basically never opens, and I am unable to use it. Does anyone have any suggestions for me? Thanks in advance.

I am running Firefox 129.0.2 (64-bit) in Windows 11 on a Surface tablet. FWIW, the extension is running fine in Chrome.

About two or three times a month the PC randomly freezes completely if a video is running in the actual Firefox browser (regardless of the site, regardless of whether it is in the active tab or in the background). First the image freezes, after about 10 seconds the sound freezes. Only a hard reset helps. The problem is observed both in actual Windows 11 and in Manjaro Linux. In games, rendering, stress tests and other PC works stably, does not freeze. How to solve this problem?

My nice big Search bar just below your logo is useless? When I highlight it, the curser blinks inside it, but when I start typing my search info it automatically types it into the small address bar on top?? I much rather use the SEARCH BAR!!!! I was able to before. Whqat's goingon??

I'm getting this error when I try to bring up Firefox. What do I do now?

Error: Platform version ‘128.0.2’ is not compatible with minVersion > = 128.0 maxVersion < = 128.0

Why doesn't Rumble work well on Firefox? Other browsers (Chrome) play the videos smoothly & quickly with no hangups or glitches, but Firefox constantly plays (eventually) audio but not video - it hangs up on the thumbnail. If I refresh about a thousand times the video will play. I thought this was a Rumble issue, but the site is smooth and problem-free on Chrome. I love using Firefox! Is there a setting I need to change, or is there an update Firefox could do? Thanks!

Every time Firefox updates it keeps re-enabling settings on its own.

Specifically 2 settings on the general tab keep enabling themselves in the "browsing" section, "Recommend extensions as you browse" and "Recommend features as you browse"

I have disabled these settings dozens of times now, and every time Firefox updates it keeps re-enabling these 2 settings on its own.

Just now I updated to v128.0 and these 2 settings turned themselves on again.

Why is Firefox not respecting my settings? Why is Firefox allowed to modify my settings without my permission?

I have deleted and reinstalled Firefox already. I don't use profiles and am not signed into the browser, so no settings are getting carried over that way.
