Opera as a Linux alternative to Netscape Browser
Updated
Our verdict
Opera GX can replace Netscape Navigator for anyone who wants a modern web browser on Linux. It renders HTML, CSS and runs JavaScript, supports tabbed browsing, HTTPS, bookmarks, history, media plugins and basic extensions. The extra gaming‑centric features (resource limits, integrated Discord/Twitch sidebar, built‑in VPN and ad blocker) are useful for gamers or streamers, but unnecessary for users who only need a lightweight, legacy‑style browser. For most people, Opera GX is a solid replacement, though it is heavier and more feature‑rich than the old Netscape product.

What is different
- Opera GX is Chromium‑based and requires more resources than the lightweight Netscape Navigator
- Opera GX includes a built‑in VPN and ad blocker, which Netscape did not have
- Opera GX has a proprietary license and is not open source, whereas Netscape was open source for a period
- Opera GX offers no legacy plugin support (NPAPI) that some old Netscape extensions used
- Opera GX has no support for the old Netscape bookmark file format (.html) out of the box
Opening your Netscape Browser files
Netscape Navigator used .html bookmark files and a proprietary history database. Opera GX does not import these formats directly. You can export Netscape bookmarks to a standard HTML file and then use Opera’s bookmark import feature, but history and cookies are not transferable without manual scripting.
Switching from Netscape Browser to Opera, step by step
- Export Netscape bookmarks to an HTML file via the old Netscape UI or a backup tool.
- Open Opera GX, go to Settings → Import Bookmarks and History, and select the exported HTML file.
- Check that bookmarks appear in the Opera sidebar and that HTTPS sites load correctly.
- If you need old cookies or session data, use a third‑party migration script or manually recreate sessions.
- Install any required extensions from the Chrome Web Store if you relied on Netscape add‑ons.
- Verify media playback and plugin functionality in Opera; replace missing plugins with modern HTML5 alternatives.
