In Google Chrome or Chromium at the Developer Tools / Settings / Devices there is a list of Emulated Devices. In it, is possible to edit, add or delete itens.
Where in the filesystem of the operating system this settings are located so I can backup, restore or manually edit all at once?
thank you very very much
It's located in preferences. More specifically, this file:
C:\Users\ **NameOfUser**\AppData\Local\Google\Chrome\User Data\ **Default**\Preferences
Default might be called Profile X where X is a number, depending on how many profiles were created or exists. (E.g. "Profile 2")
If you want to actually modify the file, you can open it up in Notepad and look for the phrase customEmulatedDeviceList

Gurus,
I am using uipath(A Ui Based Automation Tool) to download a file from a website using chrome browser.
I want browser to not prompt before downloading and just download the file in the downloads folder.
From various posts on this website i found that there exists a file called "preferences" which can be modified to solve this problem.
Before coding further i decided to do the changes in the "preferences" file manually on multiple machines, just to make sure that the changes i do in the preferences file reflect in the chrome browser as well .
I am manually modifying values for these 2 options in the preferences file.
download.default_directory
download.prompt_for_download
When i changed value for download.default_directory(Manually in Preferences file), it reflects the same in the chrome browser settings on every machine that i tested on.
But When i change value for download.prompt_for_download, it reflected in the chrome browser settings on some of the machines while on others i found that it does not reflect in the browser and rather the preferences file also seems to have reverted back to previous values.
The steps i followed are as below..
close any running instance of chrome
do the modifications in the preference file and save it
open chrome and go to settings>advance and downloads
i see DreamCatcher pointing to a similiar situation in this post, but no answers there..
I hope I can help solve your issue or at least give you some direction :)
Option#1: Chrome Settings
Wouldn't the problem be solved by changing the settings for downloads in the browser before running the bot? https://support.google.com/chrome/answer/95759?co=GENIE.Platform%3DDesktop&hl=en
Option#2: Do it in UiPath
And the other thing, is that when the prompt (to save the file) appears, couldn't you insert the path of the file that includes the default folder to save + name file + extension? (e.g. on the save path of the prompt, use type text "c:\myDocuments\downloads\filename.ext" ? I've done this in the past with UiPath...get the prompt window, type text and just modify the string being passed to carry the path, file name and extensio...then click "SAVE" or use hotkey "Enter"(if the file requires replacement, these are another 20cents you will have to program in UiPath, but it'd doable).
Option#3: Script
Another option, which I have not done, but see my friends do is creating BAT files to reset certain browser settings or the "registry"...so what they do is that they configure the BAT to do the changes to the browser and they add an activity (in UiPath) to invoke the BAT file every time the browser is opened by the robot.

" google-chrome --allow-file-access-from-files "
Like i have an app,that requires chrome to have this security restriction on local files removed.
So i cant type do this everytime i take the app.
Any ideas?
PS: It would be great if you can tell what the positives and negatives about it,as well as how to revert back if needed.
On Linux Operating System (specifically UBUNTU)
Slightly Permanent Method
Go to the menu entry/ launcher for Chrome (.desktop file)
Open the launcher properties dialog.
It should look something like this: ‘/usr/bin/google-chrome %U’
Change it to ‘/usr/bin/google-chrome --allow-access-from-files‘ to
make the flags work permanently
You may also need to delete and re-pin your launcher(s) after
modifying it. Chrome should launch with the specified flags enabled
after the modification.
PS: I found this here, haven't tried this out..
I'm trying to run multiple instances of of Chrome with different proxies. Searching the web I've found that chrome supposedly supports 'chrome.exe --proxy-server="proxy:port" ' from the command line. But I've tried that and it doesn't work.
Is there any way to run multiple instances of Chrome with different proxies?
Thanks!
The answer from gengkev is correct. For all users combing from search engines who need a quick "copy and paste" solution, use this link target (windows):
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --proxy-server="http://proxy01.your.proxy:3128" --user-data-dir="%LOCALAPPDATA%\Google\Chrome-proxy01\User Data"
Chrome will create this new folder "Chrome-proxy01" on its own. With this you can have multiple chrome shortcuts using different proxy servers.
If you're running more than one instance of chrome with different flags, I think you need to specify different paths to --user-data-dir.
As mentioned in the previous answer, the way to do that is to:
Pass a --proxy-server parameter
Pass a different user data directory path for every launch with a different proxy server
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --proxy-server="http://proxy01.your.proxy:3128" --user-data-dir="%LOCALAPPDATA%\Google\Chrome-proxy01\User Data"
Where %LOCALAPPDATA%\Google\Chrome-proxy01\User Data folder needs to be unique for any new instance that uses a different proxy. So use %LOCALAPPDATA%\Google\Chrome-proxy02\User Data for the second launch, %LOCALAPPDATA%\Google\Chrome-proxy03\User Data for the third launch etc.
I would also highly advise to use the --no-first-run flag to get rid of the annoying popup that asks you whether you want to set chrome as your default browser every time you launch it with a new data directory
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --proxy-server="http://proxy01.your.proxy:3128" --user-data-dir="%LOCALAPPDATA%\Google\Chrome-proxy01\User Data" --no-first-run
Yes, you can run it. To do so:
Install the extension SwitchyOmega in the profiles that you want to use proxy.
Create a profile with your desired name and enter the details of the proxy that you wish to use.
Save the changes using apply changes button.
Switch to your proxy using the extension button present on the top right corner of the chrome.
In addition I am also attaching extension screenshot:
As of 2014-10-05, the easiest way to run multiple versions or instances of Chrome is to use Google Chrome Portable, downloaded from:
http://portableapps.com/apps/internet/google_chrome_portable
Currently I'm running 4 separate instances of Google Chrome v37.0.2062.124. One instance is installed and three other instances of Google Chrome are portable.
Here's how my Windows 7 Taskbar looks like when all 4 instances of Chrome are opened:

If you want to change Google Chrome icon that is shown on the Windows Taskbar once Google Chrome is started, then you should follow this link:
https://superuser.com/questions/613851/is-it-possible-to-customize-taskbar-icons-if-so-how
The answer is given in comments: you need to change icons that are stored in chrome.dll using Resource Tuner (use Trial version) or Resource Hacker (free).
When you run totally separate instances of Chrome, you can make those separate Chrome instances use different proxies through Chrome settings of that particular instance of Chrome.
You can make multiple "people" (settings > manage other people > add person). You can then open a instance for each person(you don't have to login to google for the other "people"). Then you can configure a proxy for that instance.
To get the menu that's shown in the picture just click on your profile icon on the top right.
When doing webkitRequestFileSystem in window.PERSISTENT option in Google Chrome, where on my filesystem do files get written? I'd like to drop files there and have Chrome interact with them while I'm building and debugging this app.
For me, at least on Mac OSX, they're stored under /Users/USERNAME/Library/Application Support/Google/Chrome/Default/File System for me. If you're using profiles, there will be profile directories instead of Default. However, each origin's saved files/folders are obfuscated under directories that won't be easy for you to interact with.
For debugging the Filesystem API, you have a few options:
Use this extension to view/remove files.
See the tips here: http://updates.html5rocks.com/2011/08/Debugging-the-Filesystem-API
That includes viewing stored files very easily using the filesystem: URLs.
Drop the Filesystem Playground demo (http://html5-demos.appspot.com/static/filesystem/filer.js/demos/index.html) into your origin. You can use that to view/rename/delete files/folders easily.
Chrome DevTools now has support for the Filesystem API for viewing the files stored under an origin. To use that, you will need to enable the Developer Tools experiments in about:flags, restart, hit the gear in the devtools (lower right corner), and enable the 'FileSystem inspection' under the experimental tab.
Just for completeness: on linux it goes into ~/.config/google-chrome/Default/File\ System/
On Windows XP, it is here: c:\Documents and Settings\USERNAME\Local Settings\Application Data\Google\Chrome\User Data\Default\File System\.
On Windows 7, the location is C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\File System.
It's not very useful to browse it because file and dir names are obfuscated (but content in files is unchanged).
As ebidel wrote the best way is using browser of filesystem: urls that incorporated into Chrome. It's excellent! You can get the url using fs.root.toURL() where fs is a FileSystem object that you get, for example, from window.webkitRequestFileSystem().
Seems like the filesystem storage is encoded to prevent exactly what was trying to do. I ended up writing a very simple file manager available here. Start up any web server (I like mongoose for its 0 setup) and go to the /filemanager.html route
I saved a file called log.txt on MAC
It ended up at
~/Library/Application\Support/Google/Chrome/Default/Storage/ext/panbljeniblfmcakpphmjmmnpcaibipi/def/File\ System/iso/p/00/
with file name 00000 and no ext
If you are using MAC OX, and you have more than one profile on your chrome, or you cannot find default in the path, replace default with profile. But depending on number of profiles you have, it could be profile 1, profile 2, etc
I'd like to be able to take a screenshot of a page and give the user the option to save it to their desktop (with a standard OS file save prompt). Is this possible from the Chrome Extension environment? I'm not worried about the image side, more the saving to the user file system.
