Which program is the most important one on your computer? The answer is of course subjective — but for most people, it’s probably the browser. Why?
The browser is the gateway to nearly all digital services: video streaming, social media, search engines, online tools, and web apps. Many applications that used to require installation as native programs now exist directly in the browser — such as Trello or Microsoft Word. We also constantly use the browser as a tool to research information that we then use in our work.
Precisely because the browser is so central to our digital lives, it deserves more attention than we usually give it.
Important plug-ins for your browser
Ad blockers and tracking blockers play a crucial role here. Operators of ad‑funded content — meaning a large part of the internet — analyze user behavior in order to display personalized advertising. This is fundamentally legitimate, because content needs to be financed. Still, there are better ways to monetize than through the mass collection of data.
That’s why it makes sense not to make tracking unnecessarily easy. You should definitely install ad blockers and tracking‑protection extensions. In addition, many browsers themselves offer advanced protection features that go beyond the default settings. Firefox is particularly noteworthy here, but other browsers also allow you to significantly limit tracking.
I am deliberately not giving specific tool recommendations, because these change quickly and my focus is on strategies and systems — not individual tools. What is important, however, is this: Before installing anything, check how the plug‑in is financed and what other users say about it. A tracking blocker that collects data about your usage itself defeats the purpose.
Different browsers for different tasks
Many of us use more than one browser on our computers, but without a clear system. Yet it can be very useful to use different browsers for different tasks — especially if you work a lot with web apps or value privacy.
Browsers differ in speed, features, and extensibility. Some are better suited for video streaming, others for web development or sensitive activities.
A possible system could look like this:
- One browser for rarely used email accounts and online shopping
- One browser for research
- One browser for entertainment such as videos and music
Think about which categories make sense for you and which browser should take on which role.
Keep favorites bar and bookmarks up to date
If you work a lot with bookmarks, it’s worth exporting all bookmarks once a month and saving them in a cloud. This way, you can easily sync them between devices or re‑import them when switching browsers.
I personally organize bookmarks exclusively in the favorites bar and in folders. You can use the same folder structures that you use for your files. Here’s my blog post on that: LINK.
For presentations or web conferences, you should hide the favorites bar — or simply use a separate browser without bookmarks for that purpose.
Browsers on mobile devices
On mobile devices, your browser configuration is often limited. For example: On iOS, the Firefox app cannot install add‑ons, and you are heavily dependent on Apple’s definition of tracking protection.
Therefore, I recommend using mobile browsers only for occasional queries and regularly — or automatically — deleting history and cookies. Since we carry smartphones with us all the time, an extremely detailed profile of our behavior can otherwise be created.
An example:
You look up the opening hours of a restaurant and then search for flights for your next vacation. During your next search, you get ads for exactly that travel destination and recipes from the restaurant’s kitchen. Without tracking protection, this is almost unavoidable.
An important exception:
If you do not use social media professionally, remove the apps from your smartphone. Instead, log in via the browser — and don’t forget to log out again so that no data is collected in the background.
Checklist
- Write down all the purposes for which you use browsers.
- Create categories, e.g. sensitive (online banking, shopping), less sensitive (research), performance‑intensive (streaming, complex web apps).
- Decide which browser is best suited for which category.
- Install an ad blocker and tracking protection in each browser. Also check the security settings (e.g. disable password storage).
- Export your favorites regularly and back them up in the cloud to keep them synchronized across devices.
