In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

I am trying to activate the new free VPN feature, however your steps are not matching what's on my screen.

The first step from your [Set up VPN] article says:

"Look for the VPN setup prompt in the top-right corner of your Firefox toolbar.

   Click Next to begin the setup process. "

Yet I am not receiving this prompt.

I have logged into my account, encountered issues with my authenticator app and back up keys not being saved, and so signed up with a new mozilla account using my secondary google email. (This account I am raising this ticket with now. My primary account/email is [edited email from public] @gmail.com).

Hoping you can clarify or give an easy route into activating this wonderful new service you've announced. Am I right in understanding that it is different (ie. built-in and free?) to your Paid Service ?
