Your browser is where you spend most of your computing life, so small improvements compound daily. These are the changes we make on every fresh machine — the extensions, settings and habits that meaningfully speed things up, cut tracking, and stop tab chaos, without turning browsing into a hobby.
The three extensions worth installing
Resist the urge to add twenty extensions (each is a privacy and performance cost). Three earn their place. uBlock Origin (free, open-source) is the gold-standard content blocker — it speeds up pages by blocking ads and trackers and uses less memory than most blockers. Your password manager’s extension (Bitwarden, 1Password) for autofill. And a good tab manager if you are a tab hoarder (more below). That is usually enough.
Privacy settings that actually matter
In any modern browser, three toggles do most of the work. Set tracking prevention to Strict (Firefox, Edge) or install uBlock. Turn on “Send Do Not Track” and, more importantly, block third-party cookies. And review site permissions occasionally — you will find sites that quietly kept access to your camera, location or notifications. For serious privacy, Firefox and the Chromium-based Brave are stronger out of the box than stock Chrome.
Keyboard shortcuts that save real time
A handful of shortcuts remove thousands of tiny clicks. Ctrl/Cmd + T new tab, Ctrl/Cmd + W close tab, and the one nobody knows: Ctrl/Cmd + Shift + T reopens the tab you just accidentally closed — press it repeatedly to walk back through your history. Ctrl/Cmd + L jumps straight to the address bar so you can search without touching the mouse.
Taming tab overload
If you have forty tabs open “to read later,” you are using tabs as a to-do list they were never meant to be. Two fixes help: browser tab groups (built into Chrome, Edge and Firefox) let you collapse related tabs into a named, colour-coded bundle. And a read-later service like Pocket or a simple bookmarks folder gets “someday” articles out of your tab bar and off your memory. Fewer live tabs means a faster, cooler, longer-lasting machine, too.
Keyboard shortcuts that repay learning
A small set of shortcuts covers most routine navigation, and they are consistent across the major browsers. Ctrl and T opens a tab, Ctrl and W closes one, and Ctrl with Shift and T reopens the tab you just closed, which is the one people wish they had known sooner. On a Mac, substitute Cmd throughout.
Ctrl and L jumps to the address bar without touching the mouse. Ctrl and F searches the current page. Holding Ctrl while clicking a link opens it in a background tab, which is a better way to work through a list of results than opening and going back repeatedly.
What private browsing does not do
Private or incognito mode is widely misunderstood. It stops the browser recording history, cookies and form data on the local device. That is the whole of it.
Your employer or school still sees the traffic on their network. Your internet provider still sees which sites you connect to. The sites themselves still see your address and can still identify you if you log in. Private mode is useful for keeping a surprise gift off a shared computer's history, and useless as protection against network-level observation. Treating it as anonymity is the error.
Extensions are software with full access
An extension that requests permission to read and change data on all sites is asking for exactly that: it can see everything you type, including passwords and payment details, on every page you visit. Most extensions are honest and this permission is genuinely required for their function.
The risk is that popular extensions are occasionally sold to new owners who add tracking or injection, and the update arrives silently because the user already granted permission. A periodic review is worthwhile: remove anything you no longer use, and be more cautious about extensions requesting broad access than those scoped to a single site.
When a page misbehaves, try this order
Start with a hard reload, Ctrl with Shift and R, which bypasses the cache and fetches fresh copies. A great many display problems are simply a stale cached stylesheet or script.
If that fails, open the page in a private window. This runs without extensions and without existing cookies, which distinguishes a problem with the site from a problem with your profile. If the page works in private mode, the cause is local: an extension conflict, a corrupted cookie or cached data. If it fails there too, the problem is more likely with the site itself, and no amount of local clearing will fix it.
Common questions
What browser extensions should I actually install?
Keep it minimal: uBlock Origin for ad/tracker blocking, your password manager's extension for autofill, and optionally a tab manager. More extensions cost privacy and speed.
How do I reopen a tab I closed by accident?
Press Ctrl+Shift+T (Cmd+Shift+T on Mac). Repeat it to reopen multiple recently closed tabs in order.
Which browser is best for privacy?
Firefox and Brave are stronger out of the box than stock Chrome, with better default tracking protection. Adding uBlock Origin helps in any browser.
How can I stop having so many open tabs?
Use built-in tab groups to bundle related tabs, and move 'read later' pages to a service like Pocket or a bookmarks folder so they leave your tab bar.
