Review of the best extensions for Firefox browser

The well-known Mozilla Firefox browser is one of the most popular open-source browsers among Linux users. In fact, it is one of the best browsers for Linux. But how are things with extensions for it? Most probably, you prefer open-source software. Then you prefer open source extensions for that software too. If this is the case, then you can install several open source extensions in Mozilla Firefox. In this article, we will talk about them.

Dark Reader

Opens a kind of TOP of the best extensions Dark Reader - a popular browser extension that enables a dark mode for websites. The extension changes the color of the background and text to better match the dark theme. Dark Reader works well for almost any website. If you think the dark mode doesn't look good, you can further adjust the colors, contrast, brightness and grayscale.

A useful feature of the extension is that you can enable it on individual sites and disable it on all others. The option to whitelist and blacklist sites is provided. This open source project definitely values user privacy. Detailed accompanying information is provided on the project's GitHub page.

Bitwarden

Looking for the best password manager? We found one. Bitwarden is an open source password manager. It provides users with a number of features. Its advantage lies in the importance of competitive open-source solutions. A password manager in the form of a Firefox extension is no different from similar services. By installing this extension, you are guaranteed to get all the key functionality: this includes password creation, vault management and advanced options. This extension has everything you need.

Vimium-FF.

A great open-source project whose programmers were inspired by the Vim shortcuts when creating it. At first it was popular in Chrome, but after that it became available in Firefox as well. The extension was customized for Mozilla Firefox for a long time, but now there is no activity. Vimium-FF is well received by users. The extension activates hotkey combinations, which improves interaction with the browser. So the user can customize the keyboard shortcut to scroll the page, enable text mode, view source code, history or downloads. If you like to control your browser with the keys on your keyboard, then definitely try this extension.

Ublock Origin

Tired of dynamic elements of websites? The uBlock Origin content blocker will do the job perfectly. It blocks a huge amount of ads, trackers and pop-ups, resulting in faster page loading speeds. The extension also helps you if some pages are sluggish when loading. If the site works unpredictably, you can selectively allow/block javascript. Various filters are available to the user to enable aggressive blocking or minimize it. So you can balance its work, increase the speed of page loading without disrupting sites. You can read the technical specifications on GitHub.

LanguageTool

Another interesting open-source service for spell checker called LanguageTool. The developer values user privacy, so the resource is considered a good replacement for Grammarly. It is noteworthy that it is available completely free of charge, but it remains possible to purchase a license with advanced features

The free version is quite enough for a basic spell checker and typical grammatical errors. Personally, as I write this article, I have the LanguageTool extension active. Not only is it privacy-oriented and serves as an open-source alternative to other services, but it works very fast without affecting your performance. But it's worth saying that it's not full-fledged open-source. The server part is, but the extension itself is not. The developers explain that they went for it so that competitors can't take advantage of their solutions without offering anything in return. But we know that Mozilla gets access to the source code to verify each release, the extension is definitely on the recommended list.

Tabby

Finding comfort with multiple tabs in different browser windows? It is definitely worth paying attention to an extension called Tabby. The software simplifies the mechanism of managing tabs and browser windows. You can save tabs/windows to open them later.

Emoji

Users are well aware of how inconvenient and not so easy it is to add emoji on a desktop computer. But there is a solution to the problem. With an extension called Emoji, you get access to multiple emoji that are copied to the clipboard literally in one click. Emoji is distributed open-source. Some open-source fonts are used inside the extension.

DownThemAll.

Another member of the top extensions for Firefox, called DownThemAll is a powerful extension for easily downloading multiple files/media from a website page. You won't have a problem downloading all of them with one click or selecting only the ones you need. Additional options are available in the extension to customize file name, download order and advanced selection.

Tomato Clock

The last software solution if you need Pomodoro functionality in your browser. Install Tomato Clock, then you will be able to customize timers that divide your working time into intervals with short breaks. This way, your work efficiency will be improved and will be maintained without unnecessary overload. A handy extension that even has usage statistics with an overview of everything you use in the extension.
