Web: Firefox users bouncing between work and personal accounts on a daily basis are probably tired of logging in and out, or switching accounts. Thanks to the new (and overdue) Mozilla-made Multi-Account Container extension, you won't have to worry about remembering which account you're logged into. If you're unconcerned about separating work and personal accounts, you can still take advantage of multi-account browsing to preserve your privacy or discourage bad habits.

There aren't many, but Microsoft Edge does feature a selection of third-party extensions to add some functionality to the new web browser.

If you’re like me and spend way more time in front of your monitor than you should (including during the wee hours, with the room lights off), you might lament the lack of a “dark mode” on many websites. Stylish lets you fix this for most popular sites in one fell swoop.

Chrome: Facebook collects a lot of your data, but you might never get to see what they really learn about you. Data Selfie aims to give you a glimpse by letting you analyse your own Facebook usage.

Chrome: If you've ever read an article and then went through your history later to find it again, or wanted to clear specific portions of your history, Enhanced History can help.

Many of us spend most of our time on the web, but all too often browsing sessions can descend into a sprawling mess of memory-hogging, audio-playing tabs that bring your computer and your productivity to a shuddering halt. It doesn't have to be that way. These extensions and tricks can bring some simplicity back to your browsing.

Chrome: If you need a little help staying away from distracting web sites when you need to focus, or you want to give your sanity a break and block specific topics, SiteCop can help. Once installed, tell it when and how long to keep you focused, give it web addresses or keywords to block and it will do the rest.

Chrome: Online shopping may be convenient, but nothing beats free. So, when you're shopping for books on the web, Library Extension will find those same books at your local library. You can even drive to pick them up faster than they can be shipped.

Is your Facebook suddenly filled with brightly coloured, gradiented placards in the place of regular Facebook statuses? Some people seem to love them, but if you're someone who prefers to browse updates that aren't screaming in your face with vivid colours, here's some good news: there's already a 'fix' for it.

Chrome/Opera/Safari/Firefox (Beta): It's been a while since we highlighted Gmelius, the add-on that cleans up Gmail's interface. It's grown since then, and now has features to send emails later on a schedule, snooze them, bundle in useful reminders and block email trackers.

Extensions have been sorely lacking in Microsoft's internet browsers but within the last few days the company has doubled efforts in this area. It has added support for a handful of extensions for the Edge browser in the latest Windows 10 preview build and is working on a tool to let developers port Chrome extensions over. Here's what you need to know.
