The screenshot function is used in many scenarios in daily work. When you want to explain a certain problem to your partner, a picture is worth a thousand words. The so-called picture has the truth. The screenshot is usually modified under the comment, and the red box in the key place , operation steps, arrow guidance and so on.

When I was writing some interesting functions of Firefox yesterday, I needed to demonstrate some ui operation steps. At this time, the screenshots are not clear enough to record the process. I think that there are often some gif pictures on Github to demonstrate the operation steps. Use the command line to combine two pictures It is also possible to produce a gif image, which is a little troublesome. In this scenario, it is an ideal way to record the screen operation steps and then generate a gif image. Of course, it is also possible to embed a video on the website, but many platforms do not support video Upload, for simple web tutorials, pictures are more suitable.

I switched from Chrome to Firefox as my main browser a while ago due to Chrome's poor default support for Wayland. I've discovered some interesting features while using Firefox, so I'm documenting them.

Changing the System Language in Ubuntu from the Command Line

In recent years, I've primarily used Chrome, occasionally using Firefox. A few days ago, I switched to a LabWC environment and discovered that Chrome couldn't remember my passwords (keepassxc was able to handle this). Furthermore, it doesn't natively support Wayland, and the fcitx5 input method in Chrome also has issues with text distortion. I had no choice but to switch to Firefox. Observant users will notice that the Firefox title bar is much taller than Chrome, and the address bar is the same. If you're using a small-screen device like a laptop, this is simply unbearable.
