I don't know whether Firefox can import tabs from Google Chrome directly, you would have to check the import wizard (Import data from another browser). I think that you need to bookmark all tabs in Google Chrome and export these bookmarks to an HTML file. Then you can import this file in Firefox.

I want to stop using Chrome and use Firefox instead. I want to import all my open tabs to Firefox.

Hello Hemiola,
