Creation of a new profile in about:profiles > 2. Install Deepl extension, and pass the whool setup but don't login. Give the autorisation to read/write website. > 2. Serve the files with `python -m http.server` (but it was the same with Nginx) > 3. Double click on "Demo" after the loading of the index. But if I select normally a word, it seem to crash too. > 4. The tab crash In a new Nightly profile, I serve the attached testcase via a simple http server. I **do not see ** "Demo" or any other thing. It is just an empty page for me. Maybe thats why i dont get the crash. Even on Chrome, I do not see "demo", the tab is just empty. I dont know why the testcase does not show "demo" and other things for me. Do I need anything else (any js or library or something) apart from the testcase?
