在使用Internet Explorer多年之后，我不得不说，我真希望我能比我更早地切换到Firefox ！Firefox是迄今为止最可定制的浏览器，拥有数以千计的扩展和插件，您可以下载这些扩展和插件来扩展浏览器的功能。不仅有许多第三方扩展来增强Firefox，还有许多配置设置可以在Firefox本身中进行调整。
在过去的几个月里，我在Firefox中调整了很多设置，我想我会与我的Firefox读者分享其中的一些设置。我将介绍几个Firefox about:config设置，您可以更改这些设置，让您的浏览体验更加愉快。
备份 about:config 设置
在开始在Firefox中编辑 about: config 文件(config file)之前，您应该备份该文件，以防您进行的更改会搞砸一切。您可以通过制作prefs.js(prefs.js )文件的副本来备份它，该文件位于Firefox 配置(Firefox profile)文件文件夹中。无论您是在OS X、Windows 还是 Linux 上(Windows or Linux)，都有一种真正的方法可以找到 Firefox 的配置文件(Firefox)文件夹(profile folder)。
首先单击右上角(First click)的设置按钮，其中包含三个水平线。
现在在打开的菜单中，继续并单击菜单最底部的问号图标。(question mark icon)
将弹出另一个菜单，您必须在此处单击故障排除信息(Troubleshooting Information)。
最后，将在Firefox中打开一个新选项卡，您将看到一个名为Application Basics的部分。在该部分中，您应该会在Profile Folder(Profile Folder)旁边看到一个名为Show Folder的按钮。
当您单击该按钮时，它将打开资源管理器(Explorer)到当前的Firefox 配置文件(Firefox profile)。现在只需向下浏览直到看到prefs.js并将该文件复制到硬盘上的另一个位置。
修改Firefox中的 about:config配置(Configuration)
首先(First)，为非技术用户提供如何在Firefox中实际修改这些高级配置设置可能是个好主意。配置设置只是一个键名和值的表。您可以通过在浏览器地址栏中输入(browser address bar)about:config来访问所有这些。它会向您显示一个警告，表明这样做可能会使您的保修失效，您必须单击“我会小心，我保证”(I’ll be careful, I promise)按钮。
要更改键的值，只需在顶部的“搜索”(Search)文本框中输入其名称。双击该条目，您可以更改弹出框中(popup box)的值。重新启动浏览器，更改将生效。
好的，让我们开始实际的调整。一次只调整一个设置以确保它适合您的系统并且不会导致(t cause)任何不可预见的问题总是一个好主意。
在新标签中打开搜索结果
这个调整非常酷，是目前最好的调整之一。基本上(Basically)，当您从Firefox右上角的搜索框(search box)执行搜索时，它通常会加载到当前选项卡中。但是，如果您将此设置的值设置为TRUE而不是FALSE，那么每次执行搜索时，都会出现一个新选项卡并显示结果，从而使您当前的选项卡不受影响！
根据我的谷歌网络(Google web)历史，我每天进行近 50 次搜索！因此，有 50 次我不得不手动打开一个新标签来执行搜索，或者会不小心覆盖我当前正在查看的网页。
browser.search.openintab
False –默认值，设置为True以在新选项卡中加载结果
在我们继续之前只是一个简短的说明。您会注意到，一旦您更改了默认值，它将变为粗体并且状态将更改为user set。您可以对该列进行排序并快速找到您更改的所有设置。您也可以右键单击任何这些设置，然后单击重置(Reset)以将其设置回默认值(default value)。
最后打开新标签
通常，当您单击在新选项卡中打开的链接时，新选项卡将立即出现在当前选项卡之后。当新标签在所有标签的末尾打开时，我个人喜欢它。如果您也喜欢这个，请将下面的值更改为False。
browser.tabs.insertRelatedAfterCurrent
True –默认值(Default value)，设置为False以在所有选项卡的末尾加载新选项卡
安装附加组件时禁用延迟
我仍然不明白(t understand)为什么Firefox让我等待几秒钟才能安装附加组件。也许是出于安全考虑，但对于知道自己在做什么的人来说，这真的很烦人。如果你只是想安装一个附加组件而不被Firefox无用的延迟所困扰，你可以通过将值设置为 0 来禁用它。
security.dialog_enable_delay
1000 -默认值(Default value)，设置为 0 禁用延迟
切换时预览标签
如果您喜欢在Windows(Windows)中使用ALT + TAB切换程序时如何查看预览，那么您肯定希望在Firefox中启用预览。在Firefox中，您会在中心看到一个小弹出窗口(popup window)，其中每个打开的选项卡都有一个缩略图。
browser.ctrlTab.previews
False –默认值(Default value)，设置为 true 以查看预览
禁用网页预取
Firefox有一个有趣的功能，它会尝试确定您可以点击页面上的哪些链接，然后下载它们，以便更快地加载页面。例如，它会尝试自动从Google 搜索(Google search)中下载排名靠前的结果。但是，这会占用带宽，这对于互联网(Internet)连接速度慢且受限的人来说可能是个问题。要关闭它，请将值设置为 false。
network.prefetch-next
True – 默认值，设置为 False
提高网络性能
从网络的角度来看，您可以增加几个不同的设置来提高网络性能(network performance)。
network.http.max-connections控制Firefox在任何时候与任意数量的Web服务器建立的同时网络连接的数量。在最新版本的Firefox中，默认值为(default value)256。如果您有该值，请保持原样。如果您运行的是旧版本的Firefox，并且该值为 8 或 30 或类似的值，则可以将其一直增加到 256。
network.http.max-persistent-connections-per-server控制每台服务器允许的持久连接数。默认值为 6，当人们说您可以增加Firefox(Firefox)中的同时下载数量时，这通常是人们列出的值。不要超过默认值 1 或 2，因为您可能会被暂时列入黑名单。
关闭工具提示
最后，您可以通过更改配置文件(config file)摆脱每次将鼠标悬停在按钮上时弹出的所有烦人的工具提示。就个人而言，我已经知道工具栏上的每个按钮的作用，当它们弹出并覆盖其他东西时，我会很恼火！
browser.chrome.toolbar_tips
True -默认值(Default value)，将其设置为False以关闭工具提示
对某些人来说唯一可能令人烦恼的是，当您将鼠标悬停在选项卡的标题上时，它也不会弹出工具提示。如果您有时将鼠标悬停在选项卡上以查看网页的完整标题，则将此设置为 false 将阻止您查看该信息。
所以这些只是我每天使用的许多Firefox调整中的七个。(Firefox)当然，请随意在评论中添加您自己喜欢的 about:config 调整。享受！
7 Great Firefox about:config Tweaks
After usіng Internet Explorer for many years, I have to say that I rеally wish I would have switched to Firefox a lot earlier thаn I dіd! Firefox is by far the most customizable browser оut there with thousands of extensions and addons that you can download to extend the cаpаbilitieѕ of thе browѕer. Not only are thеre many thіrd-раrty extensions to enhance Firеfox, there are also manу configuration settings that can be tweaked in Firefox itself.
Over the last few months, I’ve tweaked a good number of settings in Firefox and I thought I would share some of those with my Firefox readers. I’m going to go through a couple of Firefox about:config settings that you can change that will make your browsing experience more enjoyable.
Backup about:config Settings
Before you begin editing the about:config file in Firefox, you should backup the file in case you make a change that messes everything up. You can back it up by making a copy of the prefs.js file, which is in the Firefox profile folder. Whether you are on OS X, Windows or Linux, there is a really way to find the profile folder for Firefox.
First click on the settings button at the top right with the three horizontal lines.
Now in the menu that opens, go ahead and click on the question mark icon at the very bottom of the menu.
Another menu will pop up and here you have to click on Troubleshooting Information.
Finally, a new tab in Firefox will open and you’ll see a section called Application Basics. In that section, you should see a button called Show Folder next to Profile Folder.
When you click the button, it will open Explorer to the current Firefox profile. Now just browse down till you see prefs.js and copy that file to another location on your hard drive.
Modify the about:config Configuration in Firefox
First off, it’s probably a good idea to mention how to actually modify these advanced configuration settings in Firefox for those non-techie users. The configuration settings are simply a table of key names and values. You can access all of them by typing in about:config into your browser address bar. It’ll show you a warning that doing this might void your warranty and you’ll have to click the I’ll be careful, I promise button.
To change a value for a key, simply enter its name into the Search textbox at the top. Double click on the entry and you can change the value in the popup box. Restart the browser and the changes will take effect.
Ok, so let’s get to the actual tweaks. It’s always a good idea to only tweak one setting at a time to make sure it’s suitable for your system and that it doesn’t cause any unforeseen problems.
Open Search Results in New Tab
This tweak is pretty cool and one of the best out there. Basically, when you perform a search from the search box at the top right in Firefox, it normally loads in the current tab. However, if you set the value of this setting to TRUE instead of FALSE, then every time you perform a search, a new tab will come up with the results, thereby leaving your current tab alone!
According to my Google web history, I perform almost 50 searches a day! So that’s 50 times when I would have to manually open a new tab to perform a search or would accidentally overwrite the webpage I was currently viewing.
browser.search.openintab
False – Default value, set to True to load results in a new tab
Just a quick note before we move on. You’ll notice that once you change a value from the default, it will turn bold and the status will be changed to user set. You can sort on that column and quickly find all the settings you have changed. You can also just right-click on any of those settings and click Reset to set it back to the default value.
Open New Tabs at End
Normally, when you click on a link that opens in a new tab, the new tab will appear immediately after the current tab. I personally like it when the new tab opens at the end of all the tabs. If you prefer this also, then change the value below to False.
browser.tabs.insertRelatedAfterCurrent
True – Default value, set to False to load new tab at the end of all tabs
Disable Delay When Installing Add-ons
I still don’t understand why Firefox makes me wait several seconds before I can install an add-on. Maybe it’s for security, but it’s really annoying for someone who knows what they are doing. If you just want to install an add-on without being hassled by Firefox’s useless delay, you can disable it by setting the value to 0.
security.dialog_enable_delay
1000 – Default value, set to 0 to disable delay
Preview Tabs When Switching
If you like how you can see previews when you switch between programs in Windows when using ALT + TAB, then you will definitely want to enable previews in Firefox. In Firefox, you’ll get a little popup window in the center with a thumbnail for each open tab.
browser.ctrlTab.previews
False – Default value, set to true to view previews
Disable Prefetch of Webpages
Firefox has an interesting feature whereby it tries to determine which links on a page you might click on and then downloads them so that it can load the pages faster. For example, it will try to download the top result from a Google search automatically. However, this eats up bandwidth, which can be a problem for people who have slow and limited Internet connections. To turn it off, set the value to false.
network.prefetch-next
True – Default value, set it to False
Increase Network Performance
From the networking point of view, you can increase a couple of different settings to increase network performance.
network.http.max-connections controls how many simultaneous network connections Firefox will make at any one time to any number of Web servers. In the latest version of Firefox, the default value is 256. If you have that value, leave it as is. If you are running an older version of Firefox and the value is 8 or 30 or something like that, you can increase it all the way up to 256.
network.http.max-persistent-connections-per-server controls the number of persistent connections allowed per server. The default is 6 and this is generally the value people list when they are say you can increase the number of simultaneous downloads in Firefox. Don’t go more than 1 or 2 above the default as you could be temporarily blacklisted.
Turn Off ToolTips
Finally, you can get rid of all of those annoying tool tips that pop up every time you hover your mouse over a button by changing the config file. Personally, I already know what every single button on my toolbar does and it annoys me when they pop up and cover something else!
browser.chrome.toolbar_tips
True – Default value, set it to False to turn off tooltips
The only thing that could be bothersome to some is that it will also not pop up a tooltip when you hover over the title of a tab. If you sometimes hover over a tab to see the full title of the webpage, then setting this to false will prevent you from seeing that info.
So those are just seven of many Firefox tweaks that I use on a daily basis. Of course, feel free to throw in your own favorite about:config tweaks in the comments. Enjoy!
