At this time, the Microsoft Power Automate web extension for Mozilla Firefox browser is not available in the ‘Firefox Browser Add-ons’ store. Therefore, the download and installation of the specific web extension is not currently available. Please note that Microsoft Power Automate web extension for Mozilla Firefox browser is functional if it is already installed and web automation is fully supported in Mozilla Firefox browser.
We are working on resolving the issue as soon as possible.
We will keep you posted with the latest updates.
Hi All,
Has anyone got any news on whether they have this working again?
I have periodically tried to uninstall the extension and re-install and it fails as it has done before.
Does anyone else feel that the issue may be connected with the Windows Updates?
Hi @Kitaro
Unfortunately the PAD extension for Firefox 2.27.0.2.zip that you provided did not work for me. PAD still cannot connect. So 2.27 extensions for both Firefox and Edge don't achieve connection with PAD 2.27 for me.
Reading some of the posts, do you think this issue is more associated with the Windows 11 Upgrade
2022-12 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5020880)
AND / OR
2022-12 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5021255)
Which coincidentally were applied to my laptop on the 14th December, just before the failure started to happen?
There is no mention that this is a possible or known issue with teh upgrades, but seems a possibility.
@aliastralmentions he got it to work in a Windows 10 virtual machine instead of his Windows 11 machine for example.
Thank you!
This solved my problem (in addition to running Power Automate in a fresh virtual machine version of Windows 10, instead of my Windows 11 system).
(PAD version: 2.27.00168.22340, Firefox version: 108.0.1)
For some members on the forum, this solution from andersjensenorg has worked...so can give it a try.
You can try this new extension
I'm trying to get an understanding of this and if there is a solution with any browser.
From what I am reading, the Power automate DESKTOP (PAD) which is now version 2.27.00186.22340 (on my desktop at least) does not work with web extensions older than 2.27. Is that right? Something to do with Manifest V2 going out of scope.
Our problem is that there isn't a Firefox web extension that is 2.27.xxx and once you have updated PAD to 2.27 PowerAutomate can no longer work with Firefox. AND you cannot go back to PAD 2.26 😫 ??
SO Firefox can no longer be used until a new Firefox Web Extension at 2.27 becomes available.
However.... I tried using PAD version 2.27.00186.22340 with EDGE with web extension version 2.27.0.2 and this doesn't work either 😲 It, too, cannot connect to the browser to take control of the session.
SO... just Microsoft just rolling out a Firefox extension labelled at V2.27 (or above) like the one they have rolled out for Edge won't guarantee it will start working again!
Seems all very flakey... is there an alternative to PAD which we can use in these extended PAD outage periods until Microsoft manage to stabilise the product?
Yeah, tired to re-install the previous extension file as well but that didn't help. Nor did downgrading PAD/Firefox. So now it seems that we're stuck until MS decides to upload the extension again.
