For now, you can also install web-based Chrome Apps from the Chrome Web Store, which is essentially functional web-based code enclosed in a single package that installs, resembles, and functions. Always Testing/Changing. Whether you're an everyday user, sometimes user, or in-the-trenches.
Here's the short version.
Google just issued a Chrome update with a note that says, 'This update includes 1 [critical] security fix.'
Unfortunately for the curious Chrome user, the long version doesn't say much more:
The stable channel has been updated to 81.0.4044.113 for Windows, Mac, and Linux, which will roll out over the coming days/weeks.

Security Fixes and Rewards
Note: Access to bug details and links may be kept restricted until a majority of users are updated with a fix. We will also retain restrictions if the bug exists in a third party library that other projects similarly depend on, but haven't yet fixed.
This update includes 1 security fix. Please see the Chrome Security Page for more information.
[$TBD][1067851] Critical CVE-2020-6457: Use after free in speech recognizer. Reported by Leecraso and Guang Gong of Alpha Lab, Qihoo 360 on 2020-04-04
The bug itself is still a secret, even though the Chromium core of the Chrome browser is an open source project. The software modifications that patched this hole will ultimately become public but, presumably, that they aren't now means that both the nature of the bug and how to exploit it can easily be deduced from the fix.
Even closed-source software patches that reveal changes only at the machine code level are often eagerly 'wrangled backwards' by researchers and crooks alike in order to figure out what was wrong in the first place. https://guguformula310.weebly.com/things-to-download-on-macbook.html.
Often, knowing what specific checks were added to program code in order to detect and head off potential exploits can save an attacker weeks or even months of 'black-box' bug hunting.
For example, imagine that you know a weirdly sized image might crash a pixel-processing algorithm.
That alone would be a hint of how to provoke a crash, but you still might need to try tens of billions of combinations to rediscover the bug yourself.
But now imagine that you can see clearly that the code takes special precautions – checks that weren't there before – such as blocking processing of images where the height is exactly 1.337 times the width and the corner pixels are red.

As we explained in a recent article about a Firefox zero-day hole, a use-after-free bug gets its name from a common system function called free() that programmers are supposed to call to return blocks of memory to the operating system when they're done using them.
Programmers that forget to call free() may end up hogging way more memory than they really need, which can bog down the rest of the system.
But programmers who do call free() have to be really careful not to keep on using the freed-up memory block by mistake.
Otherwise, by the time they come to rely on the data in that memory block, another process or another part of the same software may have starting using it for something else.
For example, if you read in a number that's supposed to tell you how big the next network packet is going to be, but someone else has already overwritten that number with, say, the total amount of disk space available, you could end up with an answer such as 3 billion when the right number should be no more than, say, 300.
Dangerous bugs can arise from this sort of mistake, which basically means that the software is treating untrusted data as if it can be relied upon entirely.
As we wrote last time:
[I]n some cases, use-after-free bugs can allow an attacker to change the flow of control inside your program, including diverting the CPU to run untrusted code that the attacker just poked into memory from outside, thereby sidestepping any of the browser's usual security checks or 'are you sure' dialogs.
That's the most serious sort of exploit, known in the jargon as RCE, short for remote code execution, which means just what it says – that a crook can run code on your computer remotely, without warning, even if they're on the other side of the world.
We're assuming, because this bug is dubbed critical, that it enables RCE.
What to do?
Curiously, despite a bug that's critical enough to imply that it is exploitable and that exploiting it could let a crook implant malware on your computer, Google advises that the new version 'will roll out over the coming days/weeks.'
Days might be OK, but weeks sounds too long to us, so we recommend going through the update process as as soon as you can.
Google Chrome Issues Today
Go to the About Chrome menu option (or About Chromium if you use the non-proprietary flavour of the browser) and check that you have 81.0.4044.113 or later.
If you aren't yet patched, checking the version should automatically trigger an update.
As an aside, we were hoping there would be an easy way to turn off the speech recognizer part of Chrome and thereby perhaps to neutralise this bug anyway. (Who knew there was a speech recognizer built right into the browser itself?)
But we can't find any way to configure the speech recognizer, or even a Chromium setting that acknowledges its existence at all.
We speculated that turning off microphone access in Chrome entirely might help, but we don't know whether that would be enough to prevent the buggy code being triggered anyway, given that the faulty code might be used before the 'allow microphone access' prompt shows up.
If you know how (and, better yet, if it would be a workaround for this bug), please let us know in the comments below!

Google Chrome's black screen varies with your Windows build number or version (Windows 7/8), and the browser version. Adobe premiere 2020 mac free reddit. The black screen is normally encountered by users with older builds of Chrome running on early Windows 10 builds. https://soft-groove.mystrikingly.com/blog/matlab-32-bit-download. And, if you bump into it with the latest software installed, you should try the solutions we recommend in this article.
5 Methods To Fix Google Chrome Black Screen Issue
1. Disable Chrome Extensions
Tip: If the screen is completely black and you can't access the options, then you need to access the Extensions folder on this path – C:UsersUsernameAppDataLocalGoogleChromeUser DataProfile 1 and rename the extensions folder. Re-launch chrome after renaming the folder, if an extension caused the black screen issue, it should be resolved by now. You need to enable the option to view hidden files if you are not able to access the folder.
If you are following the tip mentioned, you should refer the video below:
If the black screen issue isn't permanent, you can try disabling the extensions. A lot of users tend to have some unnecessary extensions installed. So, you need to clean up and manage the existing extensions to know if any of them is the root cause for the Google chrome black screen issue.
To disable the extensions, here's what you need to do:
- First, you need to click on the menu icon (three-dotted icon) to find the Google Chrome options.
- Now, from the options available, hover your cursor to 'More tools' option.
- You will now see the 'Extensions' option, just click it to find all of your installed extensions listed.
- There should be a toggle switch on every extension listed (as shown in the image above), simply disable all the extensions by clicking on it (they should be greyed out after disabling)
Once you disable all the extensions, re-launch chrome to see if the issue still persists, if it has been fixed, you can try enabling the extensions (one by one) to see which one caused the issue and have it removed. Imac and windows 10.
In either case, if disabling the extensions did not work out, keep trying other solutions mentioned below.
2. Disable Hardware Acceleration
Usually, it is recommended to enable the hardware acceleration to improve the performance/user experience of your application.
But, if there's a conflict (or if your system isn't capable coping up), enabling hardware acceleration might affect the performance and in this case – it might be the root cause for Google Chrome black screen issue.
So, you can try disabling the hardware acceleration by following the steps below:
- Head to the settings.
- Now, scroll down to find the advanced section, click on it to access the advanced options as shown in the image below.
- Finally, when you scroll down a bit longer, you will find the option to disable the hardware acceleration as shown in the screenshot below.

3. Resize Google Chrome Window
In case you're using Google Chrome in the full-screen mode, you should press F11 on your keyboard to exit the full-screen mode. Even if you are not, try pressing F11 to toggle the full-screen mode and see if that helps.
In either case, simply try to drag and resize the chrome window (if it's visible to you).
4. Launch Chrome in compatibility mode
For some reason, if there's a compatibility problem with the Windows build you are using, you can change the compatibility mode. For more details, refer to this video:
Here's how you can do that:
- Find Chrome's shortcut icon, and then right-click on it. If you do not find the shortcut, search for the program through the search bar and right-click on it and head to 'Open file location' to find the shortcut for Chrome.
- Now, click on the 'Properties' option and then head to the 'Compatibility' tab.
- In that tab, you need to enable the compatibility mode by ticking the option – 'Run this program in compatibility mode for' – as shown in the image below.
- Select, Windows 8/7 and click 'OK'.
- Finally, re-launch Chrome to see if the issue still persists, if it's still not resolved, you can try changing the Windows version as well.
5. Reset / Re-install Google Chrome
What's Wrong With Google Right Now
If nothing else works, resetting or re-installing Chrome will help. Considering that you've all your browsing data synced to your email account on Google Chrome or if you have no problem losing the browsing data, you can simply reset Google Chrome and then launch it again to see if the problem still persists.
If resetting does not work, you should re-install Google Chrome by downloading the latest version available.
