Hello,

Firefox YouTube HDR mode works in Full Screen Mode (FSM), Picture in Picture (PiP), but not in normal Windowed mode (WiM). This bug appeared in around Q3-Q4 2023, before that the YouTube HDR mode was available in FSM, PiP and WiM mode.

In Safari the YouTube HDR content works in FSM, PiP and WiM mode.

Firefox 115.7.0esr (64-bit) macOS Sonoma 14.3 ( I updated the system from macOS 13 in the last 2 weeks ) MacBook Pro 14", 2021 w/ Apple M1 Pro (1000 nits sustained full screen, 1600 nits peak)

This issue exists in all HDR videos what I tested on YouTube.

This morning I received an email stating: If you are running a version of Firefox equal to or older than Firefox 78 (general release or ESR) and you have a Mozilla account, you must follow these steps to ensure continued operation of your account in Firefox: I have firefox 115.7.0esr (64-bit) running on a mid 2010 macBookPro with High Sierra OS 10.13.6

My question: what does this mean? Is my FF equal or older? And is a Mozilla account the same as a FF account? PLEASE help me, by explaining exactly what I'm supposed to do and HOW and reply in simple comprehensible language, I am NOT a tech/nerd/geek and already following all these numbers has given me a headache! Thanks in advance.

My Norton virus detection software regularly finds viruses and Trojan horses in the directory: C:\program files\Mozilla Firefox Why?

It seem to happen after using Facebook or more often Craigslist. I tried putting a read only attribute on this directory, but it still happens.

Norton then requires a reboot. So it is a hassle.

Does anyone have any ideas as to what is going on?

Captive Portal remains undetected by not prompting to login to network after Hotspot session time expires

I'm using a Hotspot provided by Cisco in a library and when first connecting to the Wireless network, Firefox prompts me to login to network in order to have Internet access (expected and works fine). However, once the time session expires Firefox will sometimes prompt again to login. When this fails and internet access is abruptly ended, I've to reconnect to the Wireless network and have Firefox prompt to login.

This is a security vulnerability as someone could advertise the BSSID of the router and have victims connect to their Hotspot instead of the true one.

Tab bar sharing system color in Windows 10 (Firefox CSS)

Hello,

In Windows 10 and 11, Firefox's tab bar and other elements that may be transparent render in Windows 10 using some sort of uDWM method (speculation, I could be wrong?) rather than the traditional win32 window frame as you can see with the title bar toggled on. This leads to elements like the tab bar being black or white, depending on your theme unless you have specified otherwise in your chrome. Highlighted yellow below is my problem area.


In my CSS code, I am trying to extend the system color to be drawn to the tab bar (and in this instance, the address bar as well,) but I can't find any way to be able to do this. I have found forums that say to add -moz:appearance -moz-windows-glass, but this completely removes the window border and leaves the Firefox window unresponsive to controls. The only way to close it is if you close it through the taskbar or task manager.


Note that I am aware of .titlebar-color{color: AccentColorText; background-color: AccentColor}, but that's not what I am going for here. That still draws using Windows 10 modern UI. Windows 7 on ESR 115 or unofficially on 116 still draw with Windows Aero in all parts of this CSS code that are black (highligted yellow below.)


I can attach my CSS code if need be.


Thanks for any help!

Firefox crashes whenever I use ctrl v or right click, and pulls up a window that it crashed. Whenever I start it back up, it says it wasn't able to restore session, then restores it anyway after I press to restore it. Another thing is whenever I try and upload a file onto a site it crashes as well. I'm on Mac OS x 13 and reinstalling firefox hasn't fixed it. This is relatively sudden, it happened about around 3 days ago for the first time, and at the same time I noticed it happening certain sites also started giving me '502 Bad Gateway' errors. Does anyone know what's happening and how to fix it? Thanks in advance!

Just a couple of quick questions for CSS coding as of Firefox 115:


What CSS code refers to the shield, padlock, permissions, or all other toolbar buttons in the address bar?

When using control to select multiple tabs, what code refers to the outline and text color of the tabs?

Images attached for reference.


Thanks in advance!

How do I put bar between tabs, or, each tab inside an individual box ? I have tried many codes from various forums, but since this update, FF seems to ignore ./chrome/userChrome.css completely.

When I clicked troubleshooting mode FF unexpectedly closed my Private browsing session and all the tabs. How do I reopen them?

I did not expect FF to close on me like that. I thought that as I was in a private browsing session FF would have warned me that it was about to close had it been necessary.

I'm guessing that my open tabs have been lost permanently because you didn't warn me and that all that time I spent is now wasted.

Life is really simple except that other people make it problematic.

Using v115.7 in debian 12.

I prefer to open pdf files with the default viewer in the operating system, not on a firefox browser tab. I have gone into settings->general->applications and configured selected "Use system default application" for PDF files. If I click on a pdf file it downloads to my Downloads folder, which is the usual and preferred behaviour. If I click the downloaded files icon on firefox's toolbar, I see the file I downloaded, all good. If I open the folder with all downloaded files, and click on the file, it opens in the OS's default viewer, all good. On the other hand, if I click on the downloaded files icon on firefox's toolbar and simply select the downloaded file from the displayed list, it opens on a firefox browser tab. This is driving me bananas. How do I configure firefox to launch the default system application instead?

Can no longer add multiple Authentication Decisions to the same hostname for different certificates

For years we have been able to login to two different websites running on different ports on the same host with our Firefox browser (The last working version was 102.14.0-3.el7_9) our RHEL 7.x system. When I accessed the different sites, there was two Authentication Decisions, one sending one cert (We will call it CertA) to the system and the other listing sending a different cert (We will call that CertB) to the system, same hostname though.

I updated the Firefox browser to 115.7.0-1.el7_9 and ever since, when I navigate to the first website, it remembers the first Authentication Decision to send CertA to the system and works as intended. Then, I try to navigate to the second site and I never get prompted to pick a cert for the second site (CertB is what it should prompt for) and the connection attempt fails with a "Secure Connection Failed, Error code: SSL_ERROR_UNKNOWN_CA_ALERT" message.

If I go and delete the Authentication Decision for CertA, then go to the CertB site, I get prompted for the cert decision and I am able to login just fine. But, then if I try to go to the CertA site, I get the same error listed above.

I can use a band aid to check the "History > Always use private browsing mode" checkbox (Which never remembers the Auth. Decision) option in Firefox, then have to remember to close the browser each time I want to navigate from one site to the next. But I have never had to do that in the past and wondering if this is a new bug or if it is somehow considered a "Security Feature" or something.

I searched around the net a bit and couldn't find a way to manually add an Authentication Decision myself. Is that possible somehow with a config file edit on our Linux system somewhere?

Thanks kindly ahead of time for any consideration to my issue.
