Add an auto-update 'update extensions now' button to chrome://extensions page

Show extensions on top with toolbar.
--show-extensions-on-top

Add a button to chrome://extensions/ that allows easy packing of extensions into crx files.
TEST=Create a sample extension, pack it, then try to install it. Update packaging and getting started pages to feature new Extensions page buttons (rather than the command line).

Add skeleton for an about:net-internal page. This page contains low-level debug information that is of interest to power users, and bug investigators. The output can be filtered by using special sub-URLs. The sub-URLs themselves are listed when visiting about:net-internal, but to give an idea: about:net-internal -- everything about:net-internal/proxyservice -- all things proxy about:net-internal/proxyservice.config -- current settings about:net-internal/hostresolver.hostcache -- dns cache

Create the download folder if it doesn't exist.

Update V8 to version 1.3.9.
This version contains: API optimizations, Object creation optimizations, Enabling of missing optimizations on 64-bit port, Bug fix for forceful JS execution termination

How to make a portable Chrome (Google Chrome - Chromium)


1. Download so called 'offline' installer, by chromium take the .zip package
2. unpack/extract the content (it's 7zip kind of) with uniextract
3. unpack/extract if there is any packed .7z inside as well till you get the files.
4. select the files to replace in the portable version exactly the same folder tree

rem1: overwrite syncapi.dll from google chrome with chromium (see smaller filesize) loose google bookmark sync, so use google chrome's syncapi.dll (check for valid file signature)
rem2: crash-service.exe, rlz.dll you may not need
rem3: if u care about file size don't overwrite \resources\inspector\Images
the png's in portable are optimized to less than the half filesize using optipng - http://developer.yahoo.com/yslow/smushit/index.html

you do not need any profile files (no files in profile folder), chrome creates them by self by a fresh run except the files in \User Scripts if you want to keep user scripts. In a short faq: Q: my portable chrome comes with files in profile folder why? A: the creator want to give u his bookmarks, homepage and settings.

The important main thing in portable launcher is a user customizable launcher support in a ini all upcoming switches and is capable to clean browser catch database + files (local storage folder by chrome dependent on switch), cookies. As this one above updated.

If you fear about user privacy concern by chrome, before using one of the popular anonymity tools (in detail its all about one file called 'local state'), I advice to have a look into chrome.dll with a hexviewer. It's easier and better to remove user id, rlz, timestamp and co inside there once as running another tool required to run again and again. You can do a file compare with every search replace pattern patcher and build an universal patcher. Another way will be to compile it without, or extend launcher to erase/replace 'local state' file and delete maybe rlz.dll, if present as well.
In fact all browsers have something like that user experience metrics, feedback feature inside.
Chrome has a very low memory consume compared with others, a big part of mem usage is on plugins such as flash by 20 and more mb.
