Appeared relatively recently new mozilla Firefox 43 began blocking unfinished extensions by default. This solution was implemented by the developers in order to increase the security level of the browser.
However, for most users. who prefer the browser Mozilla Firefox I did not like this novelty, because it can cause certain inconveniences. In this article, you can learn how to enable extensions. mozile.
What is an extension
The extension is a small application that allows you to increase the functionality and usability of the browser. For example, you can install a program that will block annoying ads and spam when you visit sites, or change the default browser look to a more creative one, etc.
Add-ons are divided into three main types:
- Extensions.
Allow to add additional functions for the search engine, or replace with those that are available in other browsers. Add-ons allow you to block ads or sites that carry potential threat PC, as well as download videos from any resources or integrate with social networks.
They allow you to change the standard background of the search engine, as well as visually change the appearance or arrangement of buttons and panels. 
- Plugin.
Allows the user to interact with the most different types Internet content such as videos, games, music, etc.
The user can download these extensions from the Mozilla search engine directory. IN this directory All programs are tested and checked for malware.
However, in latest version mozily, even programs that are contained in the directory are blocked.
To install improvements, you will need to use the forced method. The following describes several ways to force installation. 
Method number 1:
- Login to Mozilla
- Enter about:config in the address bar.
- Push button
- After the security window pops up, agree to the terms.
Method number 2:
- Go to the settings panel.
- Find xpinstall.signatures.required.
- Click LMB several times.
- After the entry changes to false, you can install the improvements.
After such manipulations, you can install in Mozilla browser Firefox 43 various add-ons that will be relevant to the user. However, caution is advised in this case, as such installations may present a potential hazard.
Also, the user should take into account that when the next update of the search engine is released, all previously set parameters will be reset.
Firefox is still my favorite browser and my default browser. Despite all the strange decisions of its developers, so far there are alternative solutions to bypass them. Starting with version 43, Firefox blocks the installation of unsigned add-ons by default. Of course, this was done with the best of intentions, to ensure our safety, to prevent the spread of malicious add-ons and the like high-flown blah blah blah. Add-on developers are required to submit them to Mozilla for review and approval, after which the add-on can be shipped through the official catalog.Many users did not like this innovation, including me. For example, I use several old, but still quite working add-ons, the development of which was discontinued many years ago. And I myself modify some additions to fit my needs, of course, after such changes, the digital signature becomes invalid. Fortunately, the developers then left a parameter in the browser settings that allows you to disable the check digital signatures installed add-ons.
Starting with version 48, the freebie was covered, Firefox stopped accepting this parameter. Regardless of its value, if you try to install any unsigned extension, you will see a warning about the danger, and the installation will be blocked. But there is a way by which you can still install third-party extensions in Firefox browser.
First you need to switch Firefox updates to the ESR (Extended Support Release) channel. This is an extended support version of the browser designed for use in organizations. Installed directly on top of the current versions of Firefox, all settings remain in place, nothing flies.
Now go to the settings page by typing in the address bar about:config. There we find the parameter xpinstall.signatures.required and double-click to switch its value to false. That's all, now you can install any updates without any problems, including unsigned or modified ones. Another idiotic quirk from Firefox's "effective managers" has been successfully overcome.
Browser extensions, including Firefox, are very popular among users. With their help, the web browser receives additional functionality customized for specific needs.
Instruction
In the window that appears, select the "Get add-ons" tab. On the page that opens, you can select extensions from the "Recommended" and "Growing in popularity" sections.
Mozilla has been working on implementing WebExtensions support in Firefox for a long time, which will make this browser work with various extensions originally developed for Google Chrome and compatible browsers. In other words, the Chrome extension can be used in Firefox.
Primary stable version WebExtensions company launch in Firefox 48 Stable, which is scheduled for release on August 2 this year. True, the developers warned that, although the achieved result is the first significant step towards the goal, full compatibility with Chrome extensions in the new Firefox should not be expected yet.
However, even in this form, WebExtensions will allow Firefox users to install many different Chrome extensions in the browser. And now we will tell you how this can be done.
So how to install chrome extension in Firefox?
To begin with, we note once again that Firefox 48 supports many different Chrome extensions, but not all and not at once. Again, this is because the feature is in development (and will obviously work with it for a long time), and the Firefox browser does not support some of the functions of some extensions that Chrome supports.
Now, actually, to the point:
- installing the Chrome Store Foxified add-on
First of all, install a special add-on Chrome Store Foxified (CSF), which will be responsible for the conversion and installation of extensions. Link to the page in the official catalog Mozilla add-ons – Here . After installing this addon in the Chrome extension store, when you open it through Firefox, it will automatically change the standard button on the page of the selected extension “ Install " on " Add to Firefox” (ADD TO FIREFOX).
- installing chrome extensions in firefox
We go to the section " Extensions "Chrome Web Store, select the desired extension and click the" Add to Firefox “. Further, depending on the settings you just installed Firefox add-ons, the extension will either be installed automatically or you will install it manually. CSF can also install in Firefox extensions Chrome in the form of temporary add-ons (add-ons) for the period of one browser session. Simply put, after closing the browser, such temporarily installed add-on extensions will be automatically deleted.
The option is not quite familiar, but quite useful. For example, in the case when you just need to see how this or that Chrome extension will work in your Firefox. It will also come in handy if you have problems loading the extension due to the need for pre-authorization via account Mozilla.
After you press the " Add to Firefox” A notification line will appear at the top of the screen with two buttons like this:
The first one provides for temporary use of the extension after installation, the second one for permanent use, but only after authorization through a Mozilla account. Chrome Store Foxified add-ons can be configured to automatically choose to temporarily install Chrome extensions. For this, in Settings "Firefox select section" Add-ons “, in the list of extensions we find Chrome Store Foxified , press the button “ Settings ” next to the name of the program, scroll down the window and check the box “ Do not sign “.
How Chrome Extensions are Installed in the Firefox Browser
The CSF addon loads the selected Chrome extension and converts it from the format crx (Google's standard format for extensions) to the format xpi (standard Mozilla format), making the necessary changes to the file manifest.json and adapting it to Firefox settings, and then saves the processed file on your PC desktop or in any other location that you specify in the addon settings.
