@firefox: different way of avoiding pshared semaphores for NetBSD

NetBSD has slightly (NetBSD>=9.x) or very (NetBSD<8) broken pshared
semaphores. Fortunately, so does macOS, so there's an easy way to avoid
reaching the code relying on it which works better.

Do so for NetBSD unconditionally, and enable multiprocess unconditionally.
Avoids PR kern/55386 for NetBSD>9.0
Avoids corrupt output on major websites, webGL bugs, etc. for NetBSD<=9.0

@firefox: limit disbling multiprocess firefox to netbsd-8.

The patches might be safe to remove altogether (disabling multiprocess
should be enough), but it's not necessary for netbsd-9 in general, as
it has working pshared semaphores.

Fixes a lot of issues with Firefox, like WebGL not working.

@Updatet to 65.0

Changelog:
New

    Enhanced tracking protection: Simplified content blocking settings give users standard, strict, and custom options to control online trackers. A redesigned content blocking section in the site information panel (viewed by expanding the small “i” icon in the address bar) shows what Firefox detects and blocks on each website you visit. To learn more about content blocking, visit the Mozilla Blog.

    A better experience for multilingual users: An updated Language section in Preferences allows users to install multiple language packs and order language preferences for Firefox and websites, without having to download locale-specific versions.

    Support for Handoff on macOS: Continue browsing across devices. Pick up where you left off with iOS (via Firefox or Safari) on Firefox on Mac.

    A better video streaming experience for Windows users: Firefox now supports the next-generation, royalty-free video compression technology called AV1. Read about Mozilla’s contribution to this new open standard.

    Improved performance and web compatibility, with support for the WebP image format: WebP brings the same image quality as existing formats at smaller file sizes, which saves bandwidth and speeds up page load.

Fixed

    Various security fixes.

Changed

    Enhanced security for macOS, Linux, and Android users via stronger stack smashing protection which is now enabled by default for all platforms. "Stack smashing" is a common security attack in which malicious actors corrupt or take control of a vulnerable program.

    Firefox will now warn you when closing a window (regardless of whether you have automatic session restore enabled for restart).

    Easier performance management: The revamped Task Manager page found at about:performance now reports memory usage for tabs and add-ons.

    Improved the pop-up blocker to prevent multiple pop-up windows from being opened by websites at the same time.

Security fixes:
Not available yet.

@Update to 63.0.1

* Minimize pkgsrc specific patches.
* A build system written in Rust lang does not find a C++ header files
  from pkgsrc (non-base) GCC, this version is not buildable on NetBSD 7.
  I will investigate this problem again.

Changelog:
63.0.1
Fixed

    Snippets are not loaded due to missing element (bug 1503047)

    Print preview always shows 30% scale when it is actually Shrink To Fit
    (bug 1501952)

    Dialog displayed when closing multiple windows shows unreplaced %1$S
    placeholder in Japanese and potentially other locales (bug 1500823)


63.0
New

    Performance and visual improvements for Windows users

    Performance improvements for macOS users

    Added content blocking, a collection of Firefox settings that offer
    users greater control over technology that can track them around the
    web. In 63, users can opt to block third-party tracking cookies or
    block all trackers and create exceptions for trusted sites that don't
    work correctly with content blocking enabled.

    WebExtensions now run in their own process on Linux

    Firefox now warns about having multiple windows and tabs open
    when quitting from the main menu. The Save and Quit feature has been
    removed. You can restore your session by ticking the box for Restore
    previous session in the General->Startup options or by using Restore
    Previous Session in the main menu.

    Firefox now recognizes the operating system accessibility setting for
    reducing animation

    Added search shortcuts for Top Sites: Amazon and Google appear as Top
    Sites tiles on the Firefox Home (New Tab) page. When selected these
    tiles will change focus to the address bar to initiate a search.
    Currently in US only.


Fixed

    Resolved an issue that prevented the address bar from autofilling
    bookmarked URLs in certain cases

    Various security fixes


Changed

    In the Library, the Open in Sidebar feature for individual bookmarks
    was removed

    The option to Never check for updates was removed from about:preferences.
    You can use the DisableAppUpdate enterprise policy as a substitute.

    The Ctrl+Tab shortcut now displays thumbnail previews of your tabs and
    cycles through tabs in recently used order. This new default behavior
    is activated only in new profiles and can be changed in preferences.

log
@Update to 55.0

Changelog:
New
    Launched Windows support for WebVR, bringing immersive experiences to the web. See examples and try working demos at Mozilla VR.

    Added options that let users optimize recent performance improvements
        Setting to enable Hardware VP9 acceleration on Windows 10 Anniversary Edition for better battery life and lower CPU usage while watching videos
        Setting to modify the number of concurrent content processes for faster page loading and more responsive tab switching

    Simplified installation process with a streamlined Windows stub installer
        Firefox for Windows 64-bit is now installed by default on 64-bit systems with at least 2GB of RAM
        Full installers with advanced installation options are still available

    Improved address bar functionality
        Search with any installed one-click search engine directly from the address bar
        Search suggestions appear by default
        When entering a hostname (like pinterest.com) in the URL bar, Firefox resolves to the secure version of the site (https://www.pinterest.com) instead of the insecure version (http://www.pinterest.com) when possible

    Updated Sidebar for bookmarks, history, and synced tabs so it can appear at the right edge of the window as well as the left

    Added support for stereo microphones with WebRTC

    Pages can be simplified before printing from within Print Preview

    Updated Firefox for OSX and macOS to allow users to assign custom keyboard shortcuts to Firefox menu items via System Preferences

    Browsing sessions with a high number of tabs are now restored in an instant

    Make screenshots of webpages, and save them locally or upload them to the cloud. This feature will undergo A/B testing and will not be visible for some users.

    Added Belarusian (be) locale

Fixed
    Various security fixes

Changed
    Made the Adobe Flash plugin click-to-activate by default and allowed only on http:// and https:// URL schemes. (This change will not be visible to all users immediately. For more information see the Firefox plugin roadmap)

    Firefox does not support downgrades, even though this may have worked in past versions. Users who install Firefox 55+ and later downgrade to an earlier version may experience issues with Firefox.

    Modernized application update UI to be less intrusive and more aligned with the rest of the browser. Only users who have not restarted their browser 8 days after downloading an update or users who opted out of automatic updates will see this change.
