What is a browser extension?

Browser extensions are compact software programs that enhance or expand the features of your web browser.They can help block ads, manage passwords, improve performance, or add additional tools for working with websites. Extensions range from simple utilities like ad blockers or translators to more complex applications for working with social networks, email, or projects. Although useful, extensions can slow down your browser, cause conflicts with other programs, or become vulnerable to attackers. Therefore, it is recommended to remove outdated, unnecessary, or suspicious extensions to maintain system security and performance.

In addition, if the site is not working as it should, you can selectively allow/block JavaScript. You can also use filter lists to enable aggressive blocking or minimize it to balance your experience without disrupting the site.

Advanced features (blocking malicious domains, media files larger than a certain size) will keep your internet connection safe and fast.

You can easily deselect pre-selected filter lists if you think uBO blocks too much. For reference, Adblock Plus is installed only with EasyList, ABP filters, and Acceptable Ads enabled by default.

It is important to note that using a blocker is NOT stealing. Don’t fall for this creepy idea. The final logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.

Ads, whether “unobtrusive” or not, are only a visible part of the privacy violation tools that appear on your browser when you visit most sites. The main goal of uBO is to help users neutralize these privacy practices in a way that welcomes those users who do not wish to use additional technical means.

The password manager in the form of a Firefox extension is no different from similar services. In this extension, you get all the key functionality, starting with password creation, storage management, and advanced options.

Password theft is a serious problem. The websites and apps you use are attacked every day. If they have a security vulnerability, all your passwords can be stolen. If you use the same password for all your apps and websites, hackers can easily access your email, bank accounts, and other important data.

Digital security experts recommend using different, randomly generated passwords for each account. But how will you manage all these different passwords? Bitwarden makes it easy for you to create, store, and access your passwords.

Bitwarden stores all of your data in an encrypted vault that is synchronized across all of your devices. Because your data is fully encrypted before it leaves your device, only you have access to it. Even we at Bitwarden can’t read your data even if we wanted to. Your data is encrypted using AES-256 and PBKDF2 SHA-256.

Bitwarden is 100% open source software. Bitwarden’s code is stored on GitHub and anyone can view it, audit it, and contribute to its development.

The free version is quite enough for basic spell checking and typical grammar errors. Personally, as I write this article, the LanguageTool extension is 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.

The server side is open-source, but unfortunately the extension itself is not. The developers explained that they took this step because they didn’t want competitors to use their extension and not give anything in return.

LanguageTool is designed with an emphasis on simplicity. At the touch of a button or a keyboard shortcut, LanguageTool will check the spelling and grammar of the selected text. LanguageTool is compatible with almost any text, regardless of the source, including social networks such as Twitter or LinkedIn and online services such as Gmail.

List of supported languages: Ukrainian, English (Australian, Canadian, British, New Zealand, South African, American), French, German (Austrian, German, Swiss), Asturian, Belarusian, Breton, Galician, Greek, Danish, Spanish, Italian, Catalan (also Valencian), Chinese, Khmer, Dutch, Persian, Polish, Portuguese (Brazilian, Portuguese, Angolan, Mozambican), Romanian, Slovak, Slovenian, Tagalog, Tamil, Swedish, Tagalog, Swedish, Esperanto, and Japanese.

And also such an extension can be enabled on individual sites and disabled on all others. In addition, there is an option to create a whitelist and blacklist of sites. This is an open-source project that values the privacy of users. You can read more and test the extension on its GitHub page.

The Dark Reader extension makes the web pages dark, so that the ‘whites’ on the pages don’t hurt your eyes when you look at them at night. Well, I recognize that the dark theme is becoming a ritual today. Similarly, people just give preference to darker pages on these screens practically nothing, whether it is Windows, mobile add-ons or web pages. Dark theme has become fashionable these days.

Dark Reader is open source and was previously available only for Chrome. Now Firefox users can also install it. The extension works by changing the color scheme of the website you are visiting, by requesting it to change the dark ‘white space’.

After installing the extension, an icon appears on the browser toolbar that allows you to interact with the extension. This way you can quickly activate or deactivate the dark theme on any website. It also has a handy shortcut, Ctrl + Shift + A to add sites to the whitelist; websites that you want to automatically have ‘dark’ when you visit them.

Please keep in mind that this is the first time the extension has been ported to Firefox and the developer may have some learning curve issue. So forgive me a bit if it doesn’t work as great as it usually does in Chrome. Heck, my experience with Speed Dial 2 on Firefox was a disappointment from what I was used to in Chrome, but developers do knock out the hurdles over time.
