Opera, alternative Linux à Microsoft Internet Explorer

Mis à jour le 22 octobre 2026

Notre avis

Opera (specifically Opera GX) can serve as a replacement for Microsoft Internet Explorer for most modern web tasks on Linux. It handles HTML5, CSS3 and JavaScript just fine, can import IE bookmarks and passwords, and offers a stable, regularly updated engine. It will satisfy users who need a reliable everyday browser and appreciate built‑in ad‑blocking, VPN and resource controls. However, it does not replicate IE‑only quirks such as ActiveX, legacy document modes, or the exact rendering behavior some old intranet sites expect, so those edge cases will still need a compatibility layer or a Windows VM.

Ouvrir vos fichiers Microsoft Internet Explorer

Opera can import IE's exported bookmark HTML files and password databases via its import wizard, so moving personal browsing data is straightforward. Exporting from Opera back to an IE‑compatible format is also possible via the same bookmark export. There is no native handling of IE's proprietary .mht or .chm files; those would need separate viewers on Linux.

Questions fréquentes

Can Opera GX display sites that only work in Internet Explorer?

It will render most modern sites correctly, but pages that rely on ActiveX, VBScript or IE‑specific document modes will not work. You may need a compatibility layer like Wine or a Windows VM for those cases.

Is Opera GX free on Linux?

Yes, Opera GX is offered as a free, proprietary download for Linux, with optional paid features like a premium VPN.

Will my saved passwords and bookmarks automatically sync after switching?

Opera GX can import them during the first‑run wizard. After import, you can enable Opera Sync to keep them synchronized across devices.
