Firefox Support Forum

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?

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!

Dear Sir,

Now there is some sort of an error message of HTML5 video

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!

When I check Firefox for add ons (Manage your extensions), I see the two that I installed. When I use "Help -> Troubleshooting Information" "Application Basics": Multiprocess Windows "Remote Processes" , I see in addition: Amazon.co.uk Amazon.com DuckDuckGo eBay Wikipedia

How do I eliminate these?
