To decide which URL to load, the user agent examines each 's srcset, media, and type attributes to select a compatible image that best matches the current layout and capabilities of the display device.
Note: For example, newer formats like AVIF or WEBP have many advantages, but might not be supported by the browser. A list of supported image formats can be found in: Image file type and format guide.
Firefox-Erweiterung ‘Image Previewer’ mit Miner
If providing higher-density versions of an image for high-DPI (Retina) display, use srcset on the element instead. This lets browsers opt for lower-density versions in data-saving modes, and you don't have to write explicit media conditions.
A Firefox extension called Image Previewer was discovered today that not only displays popups, but also injects a Monero in-browser miner into Firefox. While we have seen numerous Chrome extensions injecting in-browser miners, this is the first time I have seen a Firefox addon with this behavior.
The addon will then open the page =6081&t=0.5 in an iframe. This page contains the setup script for the in-browser Monero miner. The variables used in the URL are important as well as they specify the user id associated with the miner and the throttle, which is the percentage of time that the miner threads should be idle.
This xmr.main.min.js script is the brains behind the Monero miner and contains the base64 encoded WebAssembly program that will be executed to mine for Monero. While mining, the miner will use up to 50% of the CPU processing power on the computer. This will cause the CPU to run at high intensity for a longer period of time, which could decrease the lifespan of the hardware.
Unfortunately, new services keep popping up and it has become a game of whack-a-mole for the security industry. Therefore, your installed software may not detect the URL or scripts associated with a new in-browser miner.
To combat these threats, we are pleased to announce new protections against fingerprinters and cryptominers. In collaboration with Disconnect, we have compiled lists of domains that serve fingerprinting and cryptomining scripts. Now in the latest Firefox Nightly and Beta versions, we give users the option to block both kinds of scripts as part of our Content Blocking suite of protections.
WebP is a modern image format that provides superior lossless andlossy compression for images on the web. Using WebP, webmasters and webdevelopers can create smaller, richer images that make the web faster.
Lossy WebP compression uses predictive coding to encode an image, the samemethod used by the VP8 video codec to compress keyframes in videos. Predictivecoding uses the values in neighboring blocks of pixels to predict the valuesin a block, and then encodes only the difference.
A WebP file consists of VP8 or VP8L image data, and a containerbased on RIFF. The standalone libwebp library serves as a referenceimplementation for the WebP specification, and is available fromour git repository or as a tarball.
WebP is natively supported in Google Chrome, Safari, Firefox, Edge, the Operabrowser, and by many other tools and software libraries. Developers havealso added support to a variety of image editing tools.
WebP includes the lightweight encoding and decoding library libwebpand the command line tools cwebp and dwebp for convertingimages to and from the WebP format, as well as tools for viewing, muxing andanimating WebP images. The full source code is available on thedownload page.
I replaced the screen with a nice feed of popular movies when the user tries to scroll down. I used the same API to build cards of movies with an image, title, rating and vote count. Then, on clicking one of those cards, it shows the overview with a button to watch a trailer.

Firefox is rich with choices to customize the browser for privacy by typing about:preferences#privacy in the address bar. The "standard" Enhanced Tracking Prevention blocks social media trackers, cross-site tracking cookies, and blocks tracking in private windows, cryptominers, and fingerprinting scripts. There is a "strict" mode too that might break some sites, but there are ways to whitelist Enhanced Tracking Protection for trusted sites. And for those with the time, Mozilla provides a way to customize the privacy feature.
It provides a very similar service to Google, and you can search websites, images, videos, and news in a user-friendly layout. With additional features including mobile apps, maps, translation, cloud storage and more, Yandex offers just as much functionality but with a cleaner interface.
Many websites offer Flash- or Java-based image uploaders. To use Shrunked with these websites, you'll need to find the browser-based uploader. On ImageShack, click on "Can't Upload? Try This.". On Facebook, click on "simple uploader".The source for this add-on is at
The file should load automatically and the analysis screen should appear. Remember that the tool shows all times in UTC. The main sections of this screen can be seen in the image bellow: Button to open a new HAR file Use it to start analyzing a different file.
Grouping options for the entries You can choose between showing all entries together, without separating entries related to the same page, or showing the entries associated with their page.
Timing display selector You can choose between showing the timings in the entries' table relative to the page or independent. In the first mode the timing info for that entry will start in the position relative to the entry start time compared to the page start time, and will only expand what corresponds to the entry's duration compared to the page's duration. In the second mode the timing of each entry will occupy all available space. Of course the relative mode only makes sense when the entries are grouped by page.
The free text filter is a powerful tool that allows you to create really complex searches among a har entries. The simplest way to create a search is to just write several search terms on it, like: [get drive]. This will search entries that have all those terms on their response and request. Note that quoted sentences will be treated as a single search term, so: ["number of events" week] will search that the sentence "number of events" appears somewhere on the query. Moreover the search tearms my occur as a field-term pairs like : [requst.url:term request.method:term response.status:term]. You can make even more complex queries by using operator, creating groups or indicating the field you are interested in.
From inside Firefox's main menu -- or from inside the three-lined menu on the right side of the toolbar -- select Settings. Once the Settings window opens, click Privacy & Security. From here, you'll be able to choose between three options: Standard, Strict and Custom. Standard, the default Firefox setting, blocks trackers in private windows, third-party tracking cookies and crypto miners. The Strict setting may break a few websites, but it blocks everything blocked in Standard mode, plus fingerprints and trackers in all windows. Custom is worth exploring for those who want to fine-tune how trackers are being blocked.
Core should probably be the concept of being able to cache the text (and maybe images) of all pages viewed, with versioning and reloading of new data. The user would be able to select/deselect/customise this (eg I'm researching topic x, I want everything I do stored) and be able to combine, summarise results.
Along the central management line I would like to have a GUI utility that configured every feature that could be centrally managed. The GUI would create a config file that could be placed on a web server or file system. The packaging tool would provide a way to define the location of the config file. Custom configurations for different users/groups could be accomplished by adding some variable determiners to the config GUI and config file. The configuration file could key some features off user, group membership, computer name, etc. It should be a config file with the possibility of multiple configurations nested in it, especially if this config file is to be hosted on a file system. Config files hosted on a web server could use CGI scripts, etc. to serve up a custom configuration file.
-Currently, Firefox will just resize large images to fit in the browser window. This method is adequate, but better options should be provided for users; however it's up to them to enable it or not (depending on system capability/performance),
In simple terms, if you save images that have been edited by using multiple layers, tags, and transparency as TIFF files, you can open and edit them layer by layer, which you cannot do with JPG or PNG formats.
Some notable features of the TIFF format include support for lossless compression, handling of very high-quality images, saving multiple layers of details, support storage of multiple high-quality images in a single file, etc. 2ff7e9595c
