Top Ten Firefox should avoid installation of extensions

Fasterfox

This network accelerator has a "prefetch" technology that can make you a miserable Internet citizen. Here's how it works: you download a page and start reading. When your system is free, Fasterfox silently starts the next link and starts downloading the target page. The idea is that if you decide to click on one of these links, the page is already cached on your computer, and of course it can be loaded quickly.

This extension is good for you, but it can bring incredible bandwidth waste. You just have to think about how many links you have on a webpage. Even if you don't care about bandwidth, there are reports that some system administrators are now testing this sort of extension and blocking the client that uses it. When you have the possibility to use Fasterfox reliably, you'd better not use it unless you know what you're doing.

If you have to use Fasterfox, select the "courteous" setting-it can speed up your browsing a bit and not run out of bandwidth.

NoScript

This extension is as popular as advertising, which allows you to control the JavaScript, Java executable content on the page based on the source domain of the page. You add sites you think are safe to whitelist and vice versa.

NoScript allows you to allow or disallow executable content through the source domain, but a page may have execution scripts from different domain names.

If you really need such a control, you may already be using this extension and intend to continue using it. But for ordinary users, it's really boring to get a full web browsing experience by adding a Web site to the white list.

Does NoScript make Firefox more secure? But has it won the War of pros and cons? For some reason, paranoia may seem cool to online enthusiasts, but more often than not, this extension is almost useless if you don't send in sensitive data. Almost all web browsing users of this extended audience will be removed after a fresh period.

Adblock and Adblock Plus

Obviously, when it comes to advertising filtering extensions, we have some bias, because Computerworld is a site that is maintained by advertising. We also know that these are very popular extensions. But if everyone filters ads, how can a site like ours continue to provide you with free content?

We do admit that there are some annoying spam ads out there. But we prefer to use nuke anything enhanced to kill those annoying ads, and let most of the ads show to support our favorite sites.

PDF Download

There is another popular extension like advertising, but it seems to be overkill for most users and headaches for other users. PDF download allows you to control your Firefox after clicking on a PDF file link-a dialog box pops up for you to choose to download, open, and view in HTML. You can also set your own default action so that you can skip the pop-up dialog box the next time.

In addition to the option of viewing files in HTML, it is useful for many people to be able to open a PDF document in their chosen PDF reader instead of using the Adobe Reader plugin only. Opening with external programs can be significantly faster on some systems. At the same time, viewing in HTML can sometimes take longer than opening a PDF file with a plugin from Adobe Reader.

So what's the problem? This extension encounters errors when processing certain PDFs. Some websites will send you a page to track and then turn you into a PDF file. In these cases, the extension cannot be used. When these uncommon situations occur, the PDF download is bypassed, but Firefox loses its response when we process the PDF of the turn. Compared to the slight benefits of PDF download, it creates more inconvenience.

VideoDownloader

Personal videos are getting more and more hot now, so why not install this extension? Sites such as YouTube and Google video can make it easier for you to put content online and share it with your Web name. VideoDownloader provides a way to download video from these sites for offline viewing. Doesn't that sound great?

The problem is that the extension must be connected to the network, and more often, you'll find that the "Service Unavailable" page, not the video download window, appears. Even if the download is finally started, the speed is also maddening slow.

On the left you see the page when you download it, and the right side is what you see more often.

Maybe this extension is the victim of its own success, but before the problem of the server solves, save your temper and don't install it.

Greasemonkey

Hey, wait a minute. Isn't that one of the best plugins on our list? Yes, you're right. As long as you know what you're doing, Greasemonkey is really an excellent extension. But it does cause trouble because it allows others to write javascripts running on Firefox. If a script is hostile, your system is probably in danger.

To avoid this hassle, you have to use Greasemonkey when you encounter a script that you think is safe, or you are familiar with JavaScript, or the script is good enough to evaluate in userscripts.org, and the user thinks it has no side effects.

If you don't want to do a good research, skip this extension altogether.

ScribeFire (formerly Performancing)

This expansion into the expansion warehouse looks pointless. All we have is a browser-based online blogging tool, but don't most blogs have a smooth browser-based blog editor?

Or there are some blogging systems that need this kind of application help, but we're not familiar with it. Before we came across such a blog system, we were all more willing to stick with the editor built into the blog system rather than the extension.

The above picture is the built-in editor of WordPress, Below is ScribeFire. Are you going to do both?

Admittedly, ScribeFire is an excellent software. We just don't need it this time. If you happen to be using a blogging system that doesn't have a good editor, ScribeFire will be the choice for your Extended tool box.

Trackmenot

This is another extension that is too hot to hold. Developers apparently noticed the search engine's data collection--search engines tracked your queries and set up statistics based on your queries--before that, 657,000 AOL users ' three-month query records were posted online.

This is part of the search log file provided by Trackmenot.

We are not paying no attention to privacy policies, but the technology used by Trackmenot is questionable. This extension will run in the background while you are browsing, and then send random query requests to search engines such as AOL, Yahoo, Google, and MSN. Isn't this a huge waste of resources for you and the search engine you rely on?

Tabbrowser Preferences

This extension allows you to tweak the Firefox tab settings in a number of small ways. For example, you can add a new tab button to your tab bar, or control whether a close icon appears on each label. This is very effective indeed.

The problem is that if you uninstall this extension, your label settings will not be restored. You have to undo your adjustment on the About:config page, but in fact many users don't understand or even understand. This is a bad expansion design.

The changes made by this extension are extremely subtle, but they are not the problem. If you uninstall an extension, you must do it for a reason, and once it is uninstalled, the browser should reset to its initial state.

Tabbrowser Extensions

This expansion is really huge, but it seems to be very popular in some Firefox circles-it's almost the beginning of the blind evolution of Firefox. It can give you a lot of information on the label browsing, plug-in management functions such as control. However, it is incompatible with many other extension conflicts. In fact, even its developers do not recommend that you install this extension.

When people who write generation code suggest you stop, you'd better stop and ignore the words of your Firefox buddies. In any case, this extension cannot-as it is not intended to-be upgraded to be compatible with the Firefox 2.x.

Bonus:watch out for the numbered Links 0.9 imposter

Numbered Links 0.9 doesn't do any good. By displaying the numbers next to the interactive elements in links, buttons, and other pages, it allows you to navigate the network without using your mouse. If you have previously chosen to install numbered Links 0.9, and you find it useful, there is no reason why you should not continue to use it.

However, be careful if you see it in the Add-on software list but don't remember that you installed it. It has a version has been modified by Formspy Trojan, the Trojan disguised as Firefox extension, and the name is "numbered Links 0.9." Formspy potentially collects information and sends it to a malicious site in HTML format.
