It works sometimes and then starts failing for no reason. Has anyone encountered this and knows a solution?
BP Version - 6.10.1
Chrome extension - Blue Prism Extension 6.5 - 6.10 Manifest V3

Thanks.

Yes, this is a reported issue with Blue Prism and Chrome browser extension using Manifest V3. Here's what you might be facing:

• Manifest V3 incompatibility: Chrome and Edge browsers are phasing out Manifest V2 extensions in favor of Manifest V3. The Blue Prism Extension 6.5 - 6.10 uses Manifest V3, which might have limitations compared to V2.
• Intermittent detection: Manifest V3 extensions might have limitations in communication between the browser and Blue Prism, leading to occasional detection failures.

Here are some solutions you can try:

1. Check Blue Prism Community: Several users have reported this issue on the Blue Prism community forums. Search for "The browser extension was not detected" to see if there are any updates or workarounds mentioned.

2. Upgrade Blue Prism (if possible): Blue Prism versions 7.2 and above (for version 7) and 6.10.6 and above (for version 6) include the Browser Automation Agent by default. This agent offers improved browser interaction compared to the Manifest V3 extension. Upgrading Blue Prism might resolve the issue if compatible with your system.

3. Use the Manifest V2 Impact Assessment Utility: Blue Prism offers a utility to identify if your automations rely on features not supported by Manifest V3 extensions. This can help you plan your upgrade strategy or identify areas needing adjustments.

4. Contact Blue Prism Support: If none of the above solutions work, consider contacting Blue Prism support for further assistance. They might have additional insights or recommendations specific to your environment.

Has there been any further update with this issue? We're currently running 6.10.5 and have noticed an uptick in instances of this over the past month or so. As other contributors have discussed, all suggestions (Fixed Port, Reboots, Increased throttling) have - at best - mixed success rates, and the issue is still occurring frequently enough for this to become a more significant issue.

Just to clarify, we're having this issue with both Edge and Chrome-based automations.

I’m revisiting this thread as some colleagues are still encountering this issue in version 7.3.1.

The release notes for the new 7.4 version don’t indicate that this issue has been addressed, so upgrading isn’t a viable solution at this time for this issue.

Error: The Browser Extension could not be detected

All the resolutions suggested in the KB article, as well as those from other community members, have already been tried.

Is anyone else still experiencing this problem with browser automations?

[monicab]

Yes. We are using 7.2.1 and this issue suddenly returned today.

[Nandhakumar]

We are using 6.10.5 and facing the same issue.

Failed to perform step 1 in Navigate Stage 'Launch' on page 'Launch App New' - The browser extension was not detected, please check that it has been installed and enabled. For more information, see the browser extension user guide.

hi @AJP 

I've had a similar issue before and it was during launch but the edge opened fine with the correct site so i just added in exception handling for this to catch the error at the launch stage, recover and then attach. This worked to keep the process moving without continual failures. I should also note this issue was resolved in the newer versions of blueprism so if its an option I would suggest upgrading to the latest version.

Hi, do you have solution to this?  I'm also encountering this with 7.4 version.

Good morning, All,

The Blue Prism browser extensions for 6.10.x and 7.x.x are supposed to be very different, so I think this might be a conflation of issues here.

1. In 6.10.x, the 'The browser extension was not detected,' is a known issue.  It seems to occur when there has been insufficient time between the termination of one instance of MS Edge and the initialization of the next (on the same machine).  We are currently on 6.10.2 and have seen a significant increase in this error, but we have also made changes to certain processes that make this more likely.  We are still working on addressing this.
2. There have been a number of reported issues with 7.x where the 'Launch' process times out because the BP extension does not load in time.  We are currently in testing for 7.3.1 (but likely will go to 7.3.2).  Our solution has been to use a 'Start Process' and 'Wait for Process Window' approach.  This is very similar to the approach @michaeloneil states.

I can try to connect at least one of the Launch/Start Process threads in a separate reply.

Take care,

Red

To follow up.  The link below connects to a more in-depth discussion of the trials and tribulations of MS Edge in version 7.x.
