Download a portable version of Chrome and run it, without that plugin added.
If that is not possible, use Firefox or another browser.
If that is not possible, use another computer.
I couldn’t do that tests but I have found a temporal solution. Maybe it works for someone with the same problem.
The browser(chrome) have to be opened in the correct port and with inspect before launching the command. I use the command “ionic serve --no-open”, and this way the browser doesn’t starts by default. Finally I reload chrome’s page.
This is no a solution but doing that I have less problems with ionic serve. There are times where ionic serve start to reload all the time even doing this, that times I stop ionic serve and launch ionic serve --no-open again.
I hope this be usefull for someone.
