Hi
I have being trying to automate browser based activity with UiPath 2020.2.0 beta 108. I am using Firefox for the same. Two days back the program was running completely fine. But now it is showing me error “Open Browser: Cannot communicate with the browser, please check the UiPath extension.” I have tried all the suggested steps to rectify it(1. Restarting the browser. 2. Removing the extension and adding again. 3 Tried in both 32 bit and 64 bit firefox. 4. Checking the Registry Edit). Still I am getting the same error.
Please help.
@shreearchita
is ensured that uipath extension is allowed to be active in Firefox private modus?
you can check and reconfigure in FF, just type about:addons into the adress bar and check the UiPath Addon and its settings
@ppr Thanks for the reply. I checked allow for private mode in add-on. Still getting the same error.
Did anything change as far as the browser is concerned? What is the version of your Firefox?
Hi @loginerror
Version for firefox is 74, 64bit.
I got a new issue: it is not able to communicate with other browsers as well.
As i unterstand, you already installed the extension on both chrome and firefox right ? And still you can’t use UiPath on both of them right ?
Have you tried on IE ? Also check if you have something like this on your chrome 
Few more things to try:
- update all activity packages to the latest versions (20.2.0)
- if all else fails, try to reinstall Studio from scratch
@mz3bel
Yes you are right. Even after installing extension it didn’t work. In IE, it is telling that uipath can’t communicate with the browser
