如果您还没有这样做，您应该在您的计算机上禁用Flash 。尽管它由值得信赖的Adobe运行，但它仍然是一款过时且不安全的软件(unsafe piece of software)。
Adobe Flash过去对于观看在线视频（如YouTube）和玩在线游戏来说是绝对必要的。但众所周知，史蒂夫乔布斯讨厌 Flash(Steve Jobs famously hated Flash)，当他从所有Apple产品中删除对它的支持时，Adobe Flash 的日子就屈指可数了。
Android然后放弃了支持。然后HTML5诞生了，将启动插入 Flash 垂死的身体，注定它无关紧要。
HTML5的兴起现在已经使Flash变得毫无意义，并且仍在运行它的人正在向不法分子的各种恶意软件攻击敞开大门。
因此，为了在线安全，是时候
一劳永逸地禁用Adobe Flash 。相信(Trust)我，它丝毫不会影响您的网页浏览。在这个过程中，你会让自己更安全。
禁用 Adobe Flash 的两种方法(Two Methods To
Disable Adobe Flash)
注意我说的是禁用(disable)
而不是卸载(uninstall)。虽然卸载Flash是绝对可以的，但确实没有必要。只需(Just)禁用它并保留它。
尽管您的计算机上安装了Flash，但问题实际上是浏览器。这就是潜在攻击者可以利用漏洞并植入恶意软件的地方。
因此，您必须在浏览器级别禁用它，并且有两种方法可以解决它。我今天将重点介绍Chrome和
Firefox。Safari用户不需要做任何事情，因为Flash默认是禁用的。
如果您使用Microsoft Edge，您可以阅读我关于为 Edge 禁用 Flash 的(disabling Flash for Edge)帖子。但是，您应该考虑从Edge(Edge)切换，因为Microsoft将很快将其替换为基于Chromium的版本。
安装 Flash 阻止扩展(Install a Flash Blocking Extension)
如果您想要快速而轻松的东西，那么您可以安装扩展程序/插件来为您完成这项工作。安装扩展并不总是最好的解决方案，因为它们往往会降低浏览器的速度。但是，如果您对扩展选择持保守态度，或者您不喜欢弄脏自己的双手，那么这可能最终成为您的最佳解决方案。
对于Chrome，最推荐的是Flashcontrol。安装插件后，您会看到一些尚未更新到HTML5的网络播放器无法正常工作，如下所示：
但是由于现在很多网络都运行在HTML5上，这种事情实际上并不常见。但是，由于您只是禁用Flash，而不是卸载它，因此理论上如果您想观看无法正常工作的快速视频，您可以再次启用它。但显然，您应该避免这样做。
对于 Firefox，您应该查看Flash Block Plus。
在浏览器设置中将其关闭(Switch It Off In The Browser Settings)
尽管安装扩展是最快最简单的方法，但实际上没有必要。如果您能找到进入浏览器设置的方法，您可以在……嗯，一个闪光灯中关闭Adobe Flash 。
在Chrome中，在地址栏中输入以下内容（without http://）
chrome://settings/content/flash
然后会在Chrome中显示(Chrome)Flash设置。它应该看起来像这样。
用鼠标将蓝色切换开关向左滑动，“先询问（推荐）”将变为：
下面是可选的黑名单和白名单。因此，您可以让Flash继续运行并将单个站点列入黑名单（这相当耗时且乏味），或者您可以完全阻止Flash并将某些受信任的站点列入白名单。
在Firefox中，较新版本的浏览器已删除Flash浏览器插件（尽管您仍然可以根据需要安装它）。但是旧版本的浏览器仍然会有Flash。如果您运行的是旧版本（早于52 版(Version 52)），则需要在URL
地址栏中输入：
关于：插件(about:addons)
然后单击插件(Plugins )选项卡。找到 Flash(Find Flash)并禁用它。可能需要重新启动浏览器。
Disable Adobe Flash On Your PC & Why You Would Want To
If you haven’t done it alreаdy, you should be dіsabling Flash on your computer. Although it is run by the trusted Adobe, it is nevertheless an outdated and unsafe piece of software.
Adobe Flash is something which used to be absolutely essential for things like watching online videos (such as YouTube) and playing online games. But Steve Jobs famously hated Flash and when he removed support for it from all Apple products, Adobe Flash’s days were numbered.
Android then dropped support. Then HTML5 was born, sticking
the boot into Flash’s dying body, dooming it to irrelevance.
The rise of HTML5 has now made Flash totally pointless and
those who are still running it are opening themselves up to all kinds of
malware attacks by nefarious individuals.
So in the interests of online safety, it is time to disable
Adobe Flash once and for all. Trust me, it won’t affect your web browsing in
the slightest. And you will make yourself a lot safer in the process.
Two Methods To
Disable Adobe Flash
Notice I said disable
and not uninstall. Although it is
absolutely possible to uninstall Flash, there really is no need. Just disable
it and leave it be.
Although Flash is installed on your computer, the problem is
actually the browser. That is the point where potential attackers can exploit
vulnerabilities and plant malware.
So it is at the browser level where you must disable it, and
there are two ways to go about it. I am going to focus today on Chrome and
Firefox. Safari users don’t need to do anything as Flash is disabled by
default.
If you use Microsoft Edge, you can read my post on disabling Flash for Edge. However, you should consider switching from Edge because Microsoft will be replacing it soon with a version that will be based on Chromium.
Install a Flash Blocking Extension
If you want something quick and painless, then you can go the
route of installing an extension/plugin to do the job for you. Installing
extensions is not always the best solution as they tend to slow the browser
down. But if you are conservative about your extension choices, or you don’t
like to get your hands dirty, this may end up being the best solution for you.
For Chrome, the most recommended is Flashcontrol. Once the plugin is installed, you
will see some web players which have not been updated to HTML5 not working,
like so :
But since a lot of the web now runs on HTML5, this sort of
thing is actually not that common. But since you are only disabling Flash – and
not uninstalling it – you can theoretically enable it again if you want to
watch a quick video that is otherwise not working. But obviously, you should
avoid doing that.
For Firefox, you should check out Flash Block Plus.
Switch It Off In The Browser Settings
Although installing an extension is the quickest and easiest
method, there really is no need. If you can find your way to the browser
settings, you can switch off Adobe Flash in…well, a flash.
In Chrome, type the following into the address bar (without http://)
chrome://settings/content/flash
That then brings up the Flash settings in Chrome. It should look like this.
Slide that blue toggle to the left with your mouse and “Ask
first (recommended)” will change to :
Underneath is an optional blacklist and whitelist. So you can
either keep Flash running and just blacklist individual sites (which is rather
time-intensive and tedious), or you can block Flash completely and whitelist
certain trusted sites.
With Firefox, the newer versions of the browser has removed
the Flash browser plugin (although you can still apparently install it if you
want). But older versions of the browser will still have Flash. If you are
running an older version (older than Version 52), you need to type into the URL
address bar :
about:addons
Then click on the Plugins tab. Find Flash and disable it. A browser restart may be required.
