Unable to launch Firefox browser from last night

I have running my automation programs on Firefox browser on several computers for years without any problems.

But since last night after Firefox was upgrading to version 135.0, all my programs on all computers are unable to launch Firefox browser by “open browser”.

The error message is "Open Browser: The browser failed to launch. "

If I change the Browser Type from Firefox to Edge or Chrome, it works successfully.

I tried to uninstall and reinstall the Firefox extension from Studio but it is still not working.

I am not sure if anyone else is having such problems and is able to advise.

Cheers.

This is a known issue now. You can see many tickets related to firefox latest version

As an interim solution - Either switch the browser or degrade the version of firefox. It should work as expected

Hi @sharazkm32 , thank you for the reply.

Yes, I did try to downgrade Firefox and all my programs are working.

But I guess UiPath has to update its extension to suit the latest version 135.0.

Agree. Hope UiPath will fix soon

Cheers
