FIR>57 - How to enable Firefox WebExtensions on Mozilla websites - gHacks Tech News

The hidden Firefox preference :privacy.resistFingerprinting.block_mozAddonManager removes the WebExtensions restriction. Here is how you set it: 1 - Load about:config in the Firefox web browser. You can run a search for privacy.resistFingerprinting.block_mozAddonManager just to make sure it does not exist. It does not in the most recent Firefox Nightly builds at the time of writing. 2 - Right-click in the part of the window that lists the preferences, and select New > Boolean from the context menu. 3 - Name the new Boolean value privacy.resistFingerprinting.block_mozAddonManager. Set its value to true. A value of true means that WebExtensions work normally on Mozilla's website. You can undo the change at any time by setting the preference to false on the about:config page of the browser. Mozilla added the new hidden preference to Firefox 57. It is not available in Firefox 56, and there is no option to introduce it in the browser. Firefox Stable users who run WebExtensions right now need to wait until the browser is updated to version 57 to set the preference and gain the functionality

FIR >62 - Mozilla makes it more difficult to block Firefox updates - gHacks Tech News

Closing Words: While it is generally not recommended to disable the installation of updates, it should be up to the user to make that decision in my opinion. Yes, it would be great if all users would run the latest version of Firefox but users have multiple reasons for not wanting to update. While it is more difficult to block update checking entirely in Firefox, an option to do so still exists even in Firefox 63 and future versions released after Firefox 63.

CSS - PRO TIPS - CSS element() function - [: -moz-element()]Vincent De Oliveira

element() brings CSS design to a new level, in an easily way. Few ideas that comes to my mind (some that I've already used since the last 4 years): - when you have to deal with duplicated content in advanced effects - live thumbnails of previous/next slides in a slideshow - live zoom over an image, for example in an e-commerce product page - animated background, using CSS Animations or by referencing a video, canvas or SVG - faking backdrop-filter or filter() - watermark with multiples backgrounds from Lea Verou idea - and anything you’re currently thinking of ;) Few things we can note: - prefixed for now in Firefox: -moz-element() - impact on rendering performance when using multiple reference. Not as bad as CSS filters, but still something you have to consider - there’s a CanIUse support page - Issue Chromium - Issue WebKit - No mention from IE Platform Status

FIR - SECURITY + PRIVACY - Firefox Configuration Guide for Privacy Freaks and Performance Buffs | 12Bytes.org

(via)
There is a huge selection of Firefox add-ons for tweaking privacy and security, some of the most popular of which are Adblock Plus and it’s many derivatives, NoScript, Flashblock, Ghostery, Web of Trust, BetterPrivacy, Lightbeam, Disconnect, Self-Destructing Cookies, Cookies Manager+, Request Policy, Policeman, Bluhell Firewall, RefControl, Smart Referer, HTTPS Everywhere and many, many others. With some possible exceptions, we won’t be using any of these, yet will retain much of the most important functionality offered by most of them with just a few add-ons, along with a plethora of changes to our Firefox configuration.

FIR57> - Addon Deprecated : ALternative in WebExtension (WE) - firefox-webext-list - Google Sheets

(via)
A giant table, I think it would be important to also include whether an old extension is no longer possible (deprecated), or someone just hasn't written an alternative yet, or whether there exists a planned API addition that would make it possible. Lots of alternatives are also missing a few features, and it would be good to know what's missing and why (impossible or just not yet implemented)The list is certainly not giant yet, but here's a start (based on responses from this post)/ https://www.reddit.com/r/firefox/comments/6i1fu2/webext_equivalents_to_legacy_addons/°

CSP - ABOUT:CONFIG - How to Disable the “Firefox has blocked content that isn’t secure” Message - SharePoint MMMan

I do a lot of work with Firefox, as its developer tools outshine all the other browsers, hands down. But recently I’ve been getting a lot of sites appearing without CSS. As it turns out, there’s actually “mixed content” on the page, and the default security setting is to block that content. Normally I agree with security settings in general, but I know what I’m doing, and this is just a massive annoyance. There are ways around this though. 1) You can add the toggle mixed content add-on from here https://addons.mozilla.org/en-us/firefox/addon/toggle-mixed-active-content/ 2) However, my preferred method is to disable the feature in the browser by doing the following. Enter about:config into the Firefox address bar (confirm the info message in case it shows up) & search for the preference named security.mixed_content.block_active_content. Double-click it and change its value to false. After this, you’ll be browsing without that annoying security blockage, and everything will feel back to normal.

FIR >57 - DEV - Firebug + FirePath alternative ? - Is there a CSS/XPATH checker, now that firefinder is gone? | Forum d’assistance Firefox | Assistance de Mozilla

(via)
The Developer Edition is the replacement for Firebug https://www.mozilla.org/en-US/firefox/developer/Yes, I know you can right click and copy the css or xpath, but thats not what I am asking. I am asking about the functionality that was provided by firefinder add on. Does FF offer that somewhere now that firebug was removed and added to the developer version.

CSS - FirePath :: Reviews :: Add-ons for Firefox

An alternative or Update ? Rated 5 out of 5 stars by decembre on Feb. 21, 2018 · permalink When i write an Userstyle it is (was) the primary tool i use with Firebug. Now i search an alternative for this great tool: The devtool don't give us the possibility to search or test a specific CSS selector like Firepath do. And in an other hand the DevTool is less useful than Firebug (it don't give an easy way to identify in which userstyle a CSS rule is - with an human reading way)

VIDEO - TUTO - Retour à VLC : Enregistrer une video en ligne ET la Convertir

A ce jour, il ne nous reste donc plus sur Windows que VLC comme player Multimedia Open Source. Contrairement aux autres, VLC permet assez simplement de lire et d’enregistrer des vidéos en ligne. Il permet aussi la conversion de vidéos ! Enregistrer une vidéo en ligne avec VLC J’ai pris un exemple d’enregistrement du film Amours et turbulences (2013) avec Nicolas Bedos et Ludivine Sagnier. Copiez tout d’abord l’url dans Youtube de la vidéo à enregistrer. Si vous utilisez un autre service, activez les outils développeur dans Firefox ou dans Chromium avec le raccourci Ctrl+Shift+I pour récupérer l’url de la vidéo.

FIT - TIP - MEMORY USAGE - Firefox qui rame et pas envie de le relancer ? Essayez cette astuce. - Korben

J'avais mon Firefox qui pédalait un peu dans la semoule après une grosse journée de boulot. Surement la faute à une page web trop violente ou à un plugin trop gourmand. Pas envie de le relancer et difficile d'en savoir plus... Alors en cherchant des indications sur la consommation mémoire interne de Firefox, j'ai eu l'idée d'entrer dans la barre d'url (Oui sans chercher sur un moteur de recherche. Trop fort le gars.) : about:memory Et là je suis tombé sur un bouton magique : Minimize Memory Usage. J'ai cliqué dessus et paf, plus aucun problème de ramouillage. Si j'avais su avant... Peut être que vous connaissiez déjà, peut-être pas, mais peu importe, je partage l'astuce.

FIR - CSS - What is userChrome.css? What can it do?

userChrome.css is a style sheet with special importance to Firefox. The rules in userChrome.css are applied to the user interface, and can override nearly every built-in style rule. Unfortunately, you cannot use userChrome.css to change the functional operation of Firefox; that's what extensions are for. Creating a userChrome.css file and adding style rules allows you to make changes to fonts and colors, hide unnecessary items, adjust spacing, and make other changes to the appearance of Firefox. The following examples illustrate the wide range of effects you can create, either by creating your own style recipes, or building on the work of CSS wizards sharing their talents on the web.
