One thing that annoys me about Firefox is when the Download window pops up showing me all of the past downloads. I am sure this feature may come in handy for some and must be an appreciated feature as it allows you to search them, but I typically remember what I download, when I downloaded it, and why I downloaded it. So, for me it is more of a nuisance than a privacy concern. However, if you have a shared computer or laptop, privacy and security may very well be the main concern. Either way, changing a couple settings can certainly help.
让Firefox烦恼的一件事是，当弹出“下载”窗口时，向我显示了所有过去的下载内容。 我确信此功能可能会派上用场，并且因为它可以让您搜索它们而必须成为一项值得赞赏的功能，但我通常会记得自己下载的内容，下载的时间以及下载原因。 因此，对我而言，这更多的是麻烦而不是隐私问题。 但是，如果您拥有一台共享的计算机或笔记本电脑，则隐私和安全性很可能是主要问题。 无论哪种方式，更改几个设置肯定可以帮助您。
Open Firefox and click on Tools Options and then the Privacy tab. Under Private Data check the box “Always clear my private data….” and uncheck “Ask me before clearing …” then click on the Setting button.
打开Firefox，然后单击“工具选项”，然后单击“隐私”选项卡。 在“私人数据”下，选中“始终清除我的私人数据...”框。 并取消选中“清除之前询问我...”，然后单击“设置”按钮。
In the Clear Private Data box check “Download History” and any other download add-on you might have which appears. For instance you can see I have Down Them All enabled, now click OK.
在“清除私人数据”框中，选中“下载历史记录”以及您可能拥有的所有其他下载加载项。 例如，您可以看到“我已全部关闭” ，现在单击“确定”。
Finally while still in Options, click on the Main tab and under Downloads, uncheck “Show the Downloads window …” and click OK to get out of options and accept all the changes.
最后，仍然在选项中，单击“主要”选项卡，然后在“下载”下，取消选中“显示下载窗口…” ，然后单击“确定”退出选项并接受所有更改。
Viola! Now you will not see the Download box pop up and every time you close out of Firefox all download history is cleared.
中提琴！ 现在，您将不会看到“下载”框弹出，并且每次您关闭Firefox后，所有下载历史记录都会被清除。
As I previously mentioned, I came up with this post as a means to rid what I consider an annoyance. On the other hand, this is also a great privacy and security tip.
正如我之前提到的，我想出了这篇文章，以摆脱我认为的烦恼。 另一方面，这也是一个很好的隐私和安全提示。
