A website script is a piece of code that is directly embedded into your website. Invisible to users on your website, scripts can add information to your website or pass along information to a third-party. Usually, the third party is someone you hired or a software that you bought.

If scripts are placed directly in the code of your website, the browser will load each of them individually. This can slow down your site (more on that in a bit), so many companies use a tag manager.

The most popular tag manager in automotive is Google Tag Manager (GTM). Tag managers group multiple website scripts under a single container so that when the browser loads the page, it looks like a single script. All the scripts inside the tag manager load at the same time, which can help speed up your site. While the added speed is a plus, GTM containers need to be monitored and used judiciously, as they can open your website up to risk and make the individual scripts running on your site harder to see.

If you have an excessive amount of scripts on your website, you may experience performance issues. The most strongly felt performance issue is speed. Since a browser needs to download all the linked third-party scripts during each page load, adding a high-volume of scripts to your website can slow it down noticeably.

Some scripts are written in such a way that they require asynchronous loading, meaning that your website could load in a single second, but loading all of the scripts one after another may take several more seconds. Consumers, especially those on mobile devices, really dislike waiting and may give up on your site before it fully loads. And, search engines like Google can punish slow websites by ranking them lower in organic listings.

This website has been translated to Spanish from English, and is updated often. It is possible that some links will connect you to content onlyavailable in English or some of the words on the page will appear in English until translation has been completed (usually within 24 hours). Weappreciate your patience with the translation process. In the case of any discrepancy in meaning, the English version is considered official. Thankyou for visiting esp.fda.gov/tabaco.

Go Into the Story is the official blog for The Blacklist, the screenwriting community famous for its annual top ten list of unproduced scripts. One helpful feature of Go Into the Story is its bank of downloadable movie scripts.

The titular Drew has been sharing scripts with curious readers and writers for almost two decades now and has a vast library from which to choose. A great benefit of Script-O-Rama is that it holds several drafts of certain movies, an invaluable resource for those who want to see how a Hollywood film evolves in the writing process.

I use Linux Mint 20.3 and am having the same issues. I keep scripts blocked except on trusted websites. When I view a new website, I can then unblock just what is needed to view site. I have done it this way for a few years since I started using Brave. Its one of my favourite features of using Brave. Please fix, its a great feature.

The first thing I did was to set up a Virtual Machine with Virtual Box on my main Ubuntu development PC. This way, if the sites I visited and the scripts contained therein tried to do something scary to my computer, I would just need to erase the VM without compromising my precious laptop. I installed the latest version of Ubuntu on the VM, opened the browser and went hunting.

On a site offering, amongst others, illegal streaming of table tennis matches, I noticed (in the list of JavaScripts in the DevTools Network tab) amongst third-party libraries, standard UI scripts and the all-too-frequent duplicate inclusion of the Google Analytics library (ouch!), a strangely named script with no .js extension and just a number as an URL.

The first step was quite straightforward: it required reformatting the code of the script, to add spacing and line breaks. I was left with properly indented code, but it was still full of very unreadable stuff, like the following:

The same could be applied to several other global variables declared at the beginning of the script. This whole shenanigan seemed a bit silly to me, since many other variables in the script are declared more openly a few lines later, like these:

Most global variables names, however, have been substituted with names with multiple letters, and all these names are unique. This means that it was possible for me to substitute them globally all over the script.

I substituted all of those as well, with an automated script, and many of the functions became more intelligible. Some even became perfectly understandable without further work. A function, for example, went from this:

As you can see, this function tries to determine the width of the client window, using all available cross-browser options. This might seem a bit overkill, since window.innerWidth is supported by all browsers starting from IE9.

The end result of the last series of substitutions I performed made the code even clearer, but I was still left with a very long script with a lot of functions with unintelligible names, like this one:

All of them have variable declarations at the beginning of each function, most likely the result of the obfuscation/compression technique used on the original code. It is also possible that the writer(s) of this code were very scrupulous and declared all variables at the beginning of each function, but I have some doubts about that.

The k9 function above is used diffusely in the script, so it was among the first I had to tackle. It expects two arguments, W and O and prepares a return variable (p) initialized as an empty array as well as a temporary variable (h).

Some other functions were nested inside others, because they were used only in the context of the enclosing function, or because they were part of some third-party piece of code that had been pasted verbatim within the script.
At the end of all this tedious work, I had a big script full of fairly intelligible functions, all with nice descriptive (albeit very long) names.

The script at the beginning is made out of a lot of helper functions, which often call other functions, and sometimes set variables in the global scope (yuck!). Then the main logic of the script begins, around line 1,680 of my un-obfuscated version.

The first half of the string is clearly the alphabet in lower letters, followed by numbers 0 through 9. The second half consists of random characters. Does that look like a cypher to you? If your answer is yes, you are damn right. It is, in fact, a simple substitution cypher, with a little twist.

If the current letter is present in the second half of the lary argument, it returns the corresponding letter in the lower-case alphabet in the first part of the same argument. Otherwise, it returns the current letter, unchanged. This means that the options parameter is only half encrypted, so to say.

Just by reading the name of the options above, you can guess a lot of what this script does: it will open a smartOverlay, even using a special adblockPopup. If you clickAnywhere, it will open a url. In our specific version of the script, it will not openPopsWhenInIframe, and it will not getOutFromIframe, even though it will apply an iOSClickFix. It will count popups and save the value in ppuCount, and even track performance using an imageToTrackPerformanceOn (which I can tell you, even if I omitted the URL, is hosted on a CDN). It will track ppuClicks (pop up clicks, I guess), and cautiously limit itself to a ppuQnty (likely a pop up quantity).

The main purpose of this script is to direct the user to a URL that is stored in its configuration as options['url']. The URL in the configuration I found redirected me to a very spammy website, so I will refer to this this URL as Spammy Site from now on, for the sake of clarity.

The first thing this script does is try to get a reference to the top window if the script itself is run from within in an iFrame and, if the current configuration requires it, sets that as the main window on which to operate, and sets all reference to the document element and user agent to those of the top window:

The second thing it does is a very minute detection of the current browser, browser version and operating system by parsing the user agent string. It detects if the user is using Chrome and its specific version, Firefox, Firefox for Android, UC Browser, Opera Mini, Yandex, or if the user is using the Facebook app. Some checks are very specific:

To do all this, the script has different functions for different browsers, each presumably written to circumvent the security measures of each browser, including AdBlock if it is present. Here is some of the code doing this to give you an an idea:
