User Reviews

Open With is praised for providing a useful open-with capability and is considered one of the few reliable options for this purpose. However, it is widely reported as no longer maintained, with compatibility issues on newer Firefox versions and some hardware. Installation is often complex, requiring Python and manual steps, and reliability varies across users. Overall, it can be very useful when it works, but maintenance and compatibility problems limit its usability for many.
Pros
  • Provides the core ability to open links/files in external applications directly from Firefox.
  • Widely regarded as one of the few, best add-ons for this purpose and described as actually working as designed.
  • When properly installed and configured (including the optional Python helper), it can work reliably.
  • Useful for opening media with external players (e.g., MPV, VLC, MPC-HC) and for workflows like YT-DLP.
  • Overall positive reputation as a great app / best add-on for the declared purpose.
Cons
  • No longer maintained by the developer; discontinued with reported compatibility issues.
  • Not working for many users on newer Firefox versions and some platforms (e.g., m2 Macs).
  • Installation is non-user-friendly and often requires Python and manual steps; described as 'Only for Unix geeks'.
  • Reliability concerns—some users cannot get it to work or can't obtain debugging info.

Is Open With Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Open With requires a few sensitive permissions. Exercise caution before installing.
