FB messenger voice & video no longer compatible with Firefox (Mac OS). Is there a fix or is it Meta playing nasty games with Firefox users?

I have latest FireFox, iOS & Messenger updates.

/edit: moved thread from Firefox for iOS (iPhone/iPad) to Firefox section as you have macOS.

Firefox's PDF viewer incorrectly applies user-defined font settings intended for HTML pages, resulting in illegible PDFs and requiring time-consuming workarounds.

Key Points: 1. When "Allow pages to choose their own fonts" is disabled in Firefox settings, the built-in PDF viewer renders some PDFs with incorrect fonts, replacing characters with icons and gifs. 2. This setting should only affect HTML pages, not PDFs, as PDFs are designed to maintain the author's exact formatting. 3. Current workarounds (saving/opening PDFs locally or toggling the font settings) are inconvenient and disrupt workflow. (Open a settings tab, navigate to fonts, navigate to advanced, toggle the option, select okay, return to prior tab, reload, view without error, then repeat the process to restore preferred settings.) 4. Users who prefer custom fonts for HTML content are forced to choose between readable PDFs and their preferred web browsing experience.

Background: HTML is intended to decompose information exchange in such a way that the viewer has control of aspects such as fonts; while PDF is a format designed specifically to present exactly as the author intended. The difference is the primary reason an author would choose to use pdf vs html. The issues can be reproduced with B612 and other fonts, in Firefox 127.0.2 and many earlier versions, on github repositories pages that embed pdf files, and most other pdf files opened with the viewer.

Proposed Solution: Implement a separate font control setting for the PDF viewer, allowing users to maintain their custom font preferences for HTML content while correctly rendering PDFs with the author's intended fonts. Or, simply disallow the setting to apply to the PDF Viewer.

Impact: Resolving this issue will significantly improve user experience, maintain the integrity of PDF documents, and eliminate the need for disruptive workarounds, ultimately enhancing productivity for affected users.

TeamVIEWER icon showed up on laptop this morning - my regular Mac desktop screen missing, figured out it TV was appearing under Guest User. Then I made error of downloading installer thinking my son was wanting to help me clean up my lap top from afar because I am 80 and get very confused and had asked him for help because I don't understand the tech vocabulary. Anyway, I can't get rid of it. It had someone's PW (hidden) an ID and could be 'remote controlled'. I saw a yellow caution sign appear so I stopped trying to install. but now I get a TEAM VIEWER Package that won't delete or go away.

This is very scary to a senior because EVERYONE is warning us don't click on unknowns. No one has used my laptop. I live alone. It appeared by itself this morning. And it had a Safari icon but I use only Firefox.

Thank you.

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?
