Google chrome access the microphone

Google has a funny feature that we can access from Google chrome (work with the chromium build too). We pronounce a search query and Google make the search. But my question is how Chrome can access the microphone? (there is no flash here). If Google can listen what I said, what is done to prevent a malicious website to listen what is saif in the room?

That is a good question. I believe it uses HTML5 / javascript on top of Native Client. Native Client is designed to a alllow native code to to be safely run within the client or in this case web browser. Of course, people can create hacks of the ap which allows said hackers to listen to you from your microphone without your permission. Native Client of course makes this harder. I hope I explained it correctly.

  • My macbook's performance is quite slow and it freezes I haven't shut it down in over a month. I shut it down yesterday for over 12 hours yet upon starting up again the slowness persists. Removed Google chrome application the speed arose slightly any tips?

    I haven't shut it down in over a month. I shut it down yesterday for over 12 hours yet upon starting up again the slowness persists. Removed Google chrome application the speed arose slightly any tips? I contacted a support member but unfortunately my warranty has run out, he suggested that may be a result of putting the mac into sleep constantly, and not shutting down and that there may be files i can clear to remedy the issue. Any suggestions would be greatly appreciated,
    Regards.

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    Otherwise, take the steps below when you notice the problem.
    Step 1
    Launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • When I go to (see URL below) I cannot invoke the scripts behind tabs "Overview, Manual etc " but when I use Google Chrome the Tabs all work?

    When I use Google Chrome all the tabs with links work when I access www.bose.com.au Tabs are on URL below.
    http://worldwide.bose.com/axa/en_au/web/wave_music_system_dab/page.html
    When I use Firefox I can access the URL www.bose.com.au but the tabs for Overview, In the box, Details/Manual, Reviews, and Accessories do not. Any ideas why? I have tried clearing Cookies and Cache etc from the Firefox menu as per your Q & A set up.

    Oddly, I don't see a Reviews tab (I have Overview, In the box, Details/manuals, Accessories).
    Could you try Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: [[Troubleshoot Firefox issues using Safe Mode]].
    You can restart Firefox in Safe Mode using
    Help > Restart with Add-ons Disabled
    In the dialog, click "Start in Safe Mode" (''not'' Reset)
    Any difference?

    My Page has data more than one page, it has verticle scroll bar to view all data .
    I used window.print() to print the data of webpage, but it prints only first page and left the remaining information.

  • Firefox 28, 29 and 30 load pages very slowly - Google Chrome is OK on the same PC...?

    Windows XP SP2 on a Dell Precision 340, Pentium 4, 2GB RAM, two GeForce MX4000 graphics cards, AVG Internet Security 2014. Broadband connection with download speeds up to about 27Mb/s.
    I get the same symptoms on a homebuilt system with an almost identical spec.
    Internet pages with any graphics at all load very slowly. Reliable websites like BBC News can take at least 30 seconds to open, making Firefox unusable for surfing.
    Google Chrome, on the same PC, opens the same pages in about 4 seconds.
    Firefox running under Ubuntu Studio 9, on the homebuilt PC, is also fine, so I don't think it's my internet connection.
    Firefox 30, on Windows 7 64-bit Professional with Norman Endpoint Security, is fine on my work laptop.
    What's slowng down Firefox 30 on my Windows XP machines please?

    Sorry you are having problems. Thanks for a good descriptive post. There is a testcase; see under; does the globe spin slowly ?
    Just a hunch at the moment but maybe the problem described in this thread.

  • Flash player lags bad with Firefox but not with google chrome,what is the problem ?

    Every time i try to play any game using flash player with Firefox i have a lot of lag time. I have to stop playing and wait for things to catch up to play to play any more,I do not have this problem with google chrome playing the same games.I have updated all add ons and plugins.
    == This happened ==
    Every time Firefox opened
    == about a month ago

    Everyone can blame flash player if they want, but the truth is for me I went from an earlier version that had plugin container which created lag for me. I disabled the plugin container in about:config settings, and firefox worked fine. Plugin container screwed up any videos i tried to watch on the internet by freezing, lagging, and crashing firefox. I was fine after I disabled plugin container, but then eventually some time later down the road I received a warning that i would soon be forced to update my mozilla so I eventually/reluctantly gave in and complied. At this point the same problems started again!!! I disabled plugin container again and it did help a bit right away. But this version 12.0 even with plugin container disabled with just a few tabs open I receive choppy video (like a snapshot of the video at 3 seconds in, and then another snap at 6 seconds in) I'm only seeing snapshots of the video like every 3 seconds while the audio continues on fine. That"s how bad the lag is. This is horrible performance for a browser. If I try to load a video while one is already playing, just that little bit of stress (2 youtube videos open at once) is all it takes to crash this poor performing version of firefox. I mean I can't even close the tabs after these situations and the audio sometime runs after closing for me as well. These problems did not start until the version changes of firefox and the addition of plugin container, not flash player. I have been a loyal mozilla fan, but my patients is wearing so so thin with the performance of this browser at the moment. Unfortunately I just realized for the first time ever I actually have to (against my will) install another browser just to watch videos. How sad is that? Considering watching videos is one of the main uses of a browser, I consider this version a failure. How could I not??? I guess I have no choice but to Chrome it up. I hope a fix for this problem can be found soon for I miss the great performing days of this previously top performing browser. Fingers Crossed!!!

  • Right click on Captivate 8 compatible with Google Chrome ?

    Hello all,
    I produce an e-learning tutorial having a lot of right clicks to do (i am working on Captivate 8).
    However, when I publish the content, right click works on Internet Explorer, but not on Google Chrome (accessibility desactivated).
    Is there any solution ?

    Ok, the link that you have provided did not help me very much.
    I needed to delete my profile on this machine, but after that I got stucked with error:
    You've been signed in with a temporary profile.
    You can't access your files, and files created in this profile will be deleted when you sign out.
    To fix this, sign out and try signing in later. Please see the event log for more details or contact your system administrator.
    I've used this solution:
    http://www.eightforums.com/tutorials/38817-you-ve-been-signed-temporary-profile-fix.html, which partly solved my problem (temporary profile error dissappeared), but ran into new problems, for example when I search and click for region settings I recieve
    this error in printscreen:
    Although I have managed that settings thru Control Panel/Region, but recieving upper error a little bit concerns me. Any hints?
    With best regards
