Unsupported features

You need to know about something. We're not almighty. There are things that we don't support (at least yet). The more you complain about it on GitHub or in support, the more chances that we'll support it eventually.

Download/upload files

Browsers usually can download and upload files. Our cloud browsers don't do it, so if you try to download some file, nothing will be downloaded, or at least you won't be able to access what you downloaded. Same for the upload, you won't see a file dialog, and we won't allow you to select a file to upload.

Browser extensions

Extensions are not supported for now. There's no way to install or activate any extension in a remote browser.

New browser windows

You're allowed to open multiple tabs, but multiple browser windows are not supported. It means that browser.createBrowserContext() from Puppeteer or browser.newContext() from Playwright won't do anything.
