RPI4 - Surfing the internet

Raspberry Pi 4: Chronicling the Desktop Experience – Web Browsing – Week 4

This is a weekly blog about the Raspberry Pi 4 (“RPI4”), the latest product in the popular Raspberry Pi range of computers.

This week’s blog focuses on an absolutely essential desktop activity. Surfing the web. A web browser is the quintessential desktop application. Everyone needs one, and there is not a desktop Linux distribution around that does not make a web browser available.

For Linux, there’s a web browser for every need. There’s heavyweight browsers jammed with a large feature set with addons and extensions. Then there’s leaner web browsers which still offer an attractive graphical interface. And there’s lightweight browsers including console based web browsers too.

On Raspbian, there’s a single web browser that’s officially supported. It’s Chromium.


At the time of writing, the official build built on Raspbian is Version 74.0.3729. It’s not the latest version. This release came out in 23 April 2019, and has been superseded by 75.0.3770, 76.0.3809, 77.0.3865, and 78.0.3904, so we’re missing out on a fair few improvements such as native lazy loading.

Chromium starts up quickly on the RPI4, and it’s reasonably quick to navigate. Rendering web pages is noticeably slower on the RPI4 than a less well-specced Chromebook running GalliumOS. But it’s still sufficiently nimble for light to moderate web browsing. It suffers on web sites heavily laden with JavaScript.

Smooth scrolling is enabled by default. Scrolling up and down web pages in Chromium is not particularly smooth with a weird rippling effect evident. It’s meant to animate smoothly when scrolling page content. But turning off Smooth Scrolling eliminated the rippling effect and gave a better experience.

There’s lots of options you can configure besides turning off Smooth Scrolling, available in chrome://flags.

I find that it’s worth wiping the browser cache periodically. One way is to create an alias in ~/.bashrc along the lines of

alias clean-chromium-cache=”rm -Rf ~/.cache/chromium/Default/Cache”

When you want to clean the cache, just run clean-chromium-cache. Autocomplete will reduce the number of characters you need to type, or just use a shorter name for the alias.

Chromium is a memory hog of course, but that applies on my Arch Linux box. With a few tabs and light web browsing, ps_mem reports Chromium is using almost 1GB of RAM. Even with lots of tabs open, my 4GB RAM model didn’t run into any memory problems. But you’ll probably want to run a different web browser if you’ve got the 1GB model.

I did some real-life activities with Chromium on the RPI4 such as internet shopping, reading email via Gmail, accessing Discord servers, and more besides. The experience was quite good. A big improvement compared to its predecessors.

I gave my opinion on video streaming in Chromium in my previous week’s blog. To recap, video streaming with Chromium on the RPI4 is disappointing. Given that’s a core activity when web browsing, it’s certainly a sticking point, but at least there’s various workarounds to achieve first-rate video streaming.

Some streaming services such as Netflix, Amazon Prime Video, and Spotify use the WideVine “Content Protection System”, more commonly known as DRM. If you watch to access these services, you need a WideVine plugin+browser supported integration. Unlike Chrome, Chromium doesn’t include DRM support, and it doesn’t provide WideVine support by default. So Netflix, Amazon Prime Video etc don’t work out of the box. But following the instructions at this blog together with starting Chromium with the following command lets you watch these DRM streaming services.

$ chromium-browser --user-agent="Mozilla/5.0 (X11; CrOS armv7l 6946.63.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904 Safari/537.36"

Playback is far from perfect though with DRM streams. And you can’t redirect the playback to a different media player like omxplayerGUI to make full use of the RPI4’s hardware acceleration.

Other Web Browsers

I experimented with other web browsers during the course of this week.

The most popular web browser is Chrome. Chrome is based on Chromium, but Google adds a number of proprietary, closed-source bits to their Chrome browser that Chromium lacks. Chrome is not available for the RPI4.


Vivaldi is a proprietary freeware cross-platform web browser. There is Vivaldi for Linux ARM, including the RPI4. You can download a package from Vivaldi’s website. You get Vivaldi 2.9.1705.

Installing the deb package with dpkg didn’t work:

$ sudo dpkg -i ./vivaldi-stable_2.8.1664.44-1_armhf.deb

complaining that libappindicator3-1 wasn’t installed. This was easily fixed by running the command:

$ sudo apt --fix-broken install

I’m really impressed with the performance of Vivaldi. The rendering speed of web pages is slightly faster than Chromium. Streaming video from YouTube and other sites is smoother than under Chromium (but not as smooth as using omxplayerGUI in conjunction with Chromium).

Like Chromium, Vivaldi is a memory hog. With just 2 tabs, one with a running YouTube video stream, the browser consumes about 600MB of RAM. Again this isn’t a web browser for the 1GB model, but with 4GB there’s plenty of memory to have multiple tabs open, and still run other software like Mathematica, LibreOffice, and other memory heavy apps.

Playback of HTML5 proprietary media works out of the box, but I ran into a Protected Content Error when trying to view a video on Amazon Prime. The error message suggested a solution for Chrome, not Vivaldi. There’s a script sudo /opt/vivaldi/update-widevine –system that restarts the Widevine installation process. But that script doesn’t work on ARM.

Instead, visit this GitHub repository. It hosts a widevine-flash_armhf.sh script that extracts Widevine and Flash binaries for Linux ARMhf from ChromeOS recovery images. Download the script (as a zip), uncompress the zip file, change into the directory, make the script executable with chmod u+x, and run the script.

The script deposits the file widevine-flash-20191029_armhf.tgz. Run the command:

sudo tar -C/ -xf widevine-flash-20191029_armhf.tgz

Viewing Amazon Prime with Vivaldi is not perfect, but it’s watchable.


While the days of Firefox being the number 1 web browser are long gone, it still retains a significant usage share. Raspbian’s repository hosts an ancient Firefox package. It’s version 60.9.0 ESR. That version was released nearly 2 years ago. A long way from the current supported official releases (Firefox 70.0, 68.2.0, and 68.2.0 ESR).

There’s no optimizations applied by Raspbian to Firefox. And there’s lots of sticking points using Firefox on the RPI4. For example, using Firefox to surf the web interferes with video playback. Watching a video on VLC is disrupted by scrolling a web page in Firefox. That doesn’t happen when using Chromium or Vivaldi.

For general web browsing, Firefox seems to work satisfactory in other respects. But using old versions of Firefox poses a significant security risk. So I cannot recommend using Firefox on the RPI4.

UPDATE: In Week 26, I revisit Firefox, as the Raspbian repositories offer a current version of this web browser.

Midori Browser

Midori Browser is billed as a lightweight, fast, free and open-source browser. It used to be the recommended web browser for earlier models of the Raspberry Pi. I’ve run out of time this week to fully test Midori on the RPI4. But I can say it’s a disaster for streaming video. Basic web browsing seems reasonable, and it definitely offers a smaller memory footprint to the web browsers above.

If you’ve used this web browser extensively on the RPI4, please share your comments.


I always prefer open source software to freeware. But given that I’m not satisfied with the web surfing performance of Chromium on the RPI4, and the Firefox package is prehistoric in browser terms, the best solution in my opinion is currently Vivaldi. It’s fast at rendering web pages with good (but not perfect) video playback. For video streaming, Chromium with omxplayerGUI has the edge.

Generally I prefer web browsing with a graphical interface. I’ve not tested text based web browsers for this week’s blog, but it’s certainly something I’ll investigate and post my findings in a later edition.

UPDATE: In Week 26, I revisit Firefox, as the Raspbian repositories offer a current version of this web browser.

  1. Midori was renewed and relaunched some time ago, and it is far from complete. I would say it’s useable, but not more.

    A recommendation can be falkon (former qupzilla), a fast browser with relatively small footprint. It’s not perfect, but my browser for 99.9% of use. I use it on a thin client and would not change.


  2. Thanks Luke. I’ve enjoyed these blog posts and found them really helpful and time saving. For anyone installing Vivaldi, there’s a small typo in the bit about the missing library. It needs another ‘minus’ in front of fix and should read:

    sudo apt –fix-broken install

    You can also find the library in Raspian’s Add / Remove Software before running dpkg.

    1. Thanks for your kind words.

      The sudo line already has two minuses before the word fix, although I agree that’s not very clear when output with the site’s css code.

      1. Yeah, I see on the site mine’s rendered exactly the same as yours and if you copy and paste it, it comes out as one long dash. Hopefully it will be clear to anyone following they need to type ‘minus minus fix’.
