Oracle VirtualBox是由德国InnoTek软件公司出品的虚拟机软件，现在则由甲骨文公司进行开发，是甲骨文公司xVM虚拟化平台技术的一部份。它提供用户在32位或64位的Windows、Solaris及Linux 操作系统上虚拟其它x86的操作系统。用户可以在VirtualBox上安装并且运行Solaris、Windows、DOS、Linux、OS/2 Warp、OpenBSD及FreeBSD等系统作为客户端操作系统。
与同性质的VMware及Virtual PC比较下，VirtualBox独到之处包括远程桌面协议（RDP）、iSCSI及USB的支持，VirtualBox在客户机操作系统上已可以支持USB 2.0的硬件设备，不过要安装 virtualbox extension pack.

Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust.
Basilisk as an application is primarily a vessel for development of the XUL platform it builds upon, and additionally a potential replacement for Firefox to retain the use of Firefox Extensions.
Basilisk is development software. This means that it should be considered more or less “beta” at all times; it may have some bugs and is provided as-is, with potential defects. Like any other Free Software community project, it comes without any warranty or promise of fitness for any particular purpose. That being said: of course we will do our best to provide an as stable and secure browser as possible with every official release of Basilisk.

What is Sumatra PDF?
Sumatra PDF is a free PDF, XPS, DjVu, CBZ and CBR reader for Windows.
Sumatra PDF is small and starts up very fast.
Simplicity of the user interface has a high priority.
Portable version included (a single executable that can be run e.g. from USB drive and doesn’t write to registry).
3.6 (2026-03-17)
add DisableAntiAlias advanced setting and CmdToggleAntiAlias command
add CmdShowAnnotations, CmdHideAnnotations, CmdToggleShowAnnotations commands for temporarily hiding / showing annotations
add CmdToggleInverseSearch to temporarily disable mouse click invoking tex inverse search
add bgcolor, opacity, textsize, borderWidth arguments to CmdCreateAnnot* commands
add Annotations.FreeTextBackgroundColor and Annotations.FreeTextOpacity advanced settings
sort thumbnails on home page by most recently used date. Set advanced setting HomePageSortByFrequentlyRead = true to revert to pre-3.6 behavior of sorting by frequency of use.
support brotli compression in PDF files
in Command Palette, if you start search with : we show everything (like in 3.5)
in Command Palette, when viewing opened files history (#), you can press Delete to remove the entry from history
improved zooming:
zooming with pinch touch screen gesture or with ctrl + scroll wheel now zooms around the mouse position and does continuous zoom levels. Used to zoom around top-left corner and progress fixed zoom levels shown in menu
include manual (F1 to launch browser with documentation)
add LazyLoading advanced setting, defaults to true. When restoring a session lazy loading delays loading a file until its tab is selected. Makes SumatraPDF startup faster.
new commands in command palette (Ctrl + K):
CmdCloseAllTabs : “Close All Tabs”
CmdCloseTabsToTheLeft : “Close Tabs To The Left”
CmdDeleteFile: “Delete File”
CmdToggleFrequentlyRead : “Toggle Frequently Read”
CmdToggleLinks : “Toggle Show Links”
CmdInvokeInverseSearch
CmdMoveTabRight (Ctrl + Shift + PageUp), CmdMoveTabLeft (Ctrl + Shift + PageDown) to move tabs left / right, like in Chrome
add ability to provide arguments to some commands when creating bindings in Shortcuts:
CmdCreateAnnot* commands take a color argument, openedit to automatically open edit annotations window when creating an annotation, copytoclipboard to copy selection to clipboard and setcontent to set contents of annotation to selection
CmdScrollDown, CmdScrollUp : integer argument, how many lines to scroll
CmdGoToNextPage, CmdGoToPrevPage : integer argument, how many pages to advance
CmdNextTabSmart, CmdPrevTabSmart (Smart Tab Switch), shortcut: Ctrl + Tab, Ctrl + Shift + Tab
added UIFontSize advanced setting
removed TreeFontWeightOffset advanced setting
increase number of thumbnails on home page from 10 => 30
add ShowLinks advanced setting and “Toggle Show Links” (CmdToggleLinks) for command palette
default ReuseInstance setting to true
added Key arg to ExternalViewers advanced setting (keyboard shortcut)
added Key arg to SelectionHandlers advanced setting (keyboard shortcut)
improved scrolling with mouse wheel and touch gestures
theming improvements
go back to opening settings file with default .txt editor (notepad most likely)
don’t exit fullscreen on double-click. must double-click in upper-right corner
when opening via double-click, if Ctrl is pressed will always open in new tab (vs. activating existing tab)
register for handling .webp files
bug fix: Del should not delete an annotation if editing content
bug fix: re-enable tree view full row select
change: CmdCreateAnnotHighlight etc. no longer copies selection to clipboard by default. To get that behavior back, you can use copytoclipboard argument instead.
change: Ctrl + Tab is now CmdNextTabSmart, was CmdNextTab. Ctrl + Shift + Tab is now CmdPrevTabSmart, was CmdPrevTab. You can re-bind it if you prefer old behavior
CmdCommandPalette takes optional mode argument: @ for tab selection, # for selecting from file history and > for commands.
command palette no longer shows combined tabs/file history/commands. CmdCommandPalette only shows commands. Because of that removed CmdCommandPaletteNoFiles because now `CmdCommandPalette behaves like it
removed CmdCommandPaletteOnlyTabs, replaced by CmdCommandPaletteNoFiles @
Ctrl + Shift + K no longer active, use Ctrl + K. You can restore this shortcut by binding it to CmdCommandPalette > command.
add Name field for shortcuts. If given, the command will show up in Command Palette (Ctrl + K)
closing a current tab now behaves like in Chrome: selects next tab (to the right). We used to select previously active tab, but that’s unpredictable and we prefer to align SumatraPDF behavior with other popular apps.
swapped key bindings: i is now CmdTogglePageInfo, I is CmdInvertColors. Several people were confused by accidentally typing i to invert colors, is less likely to type it accidentally
allow creating custom themes in advanced settings in Themes section. See docs.
improve scrolling with middle click drag #4529
make built-in keyboard shortcuts work on non-us keyboards (cyrillic , hebrew etc.)
add CmdDuplicateInNewTab (Open Current Document In New Tab) command
