Running firefox-esr on buster I don't seem to be able to install addons. I tried selenium IDE and katalon. Has Debian blocked the installation of addons? I don't see indications of that in the docs or the net.
Likewise, I know selenium (and maybe katalon) have had compatibility issues with some versions of FF, but the page from which I installed the addons (which was via the addon manager in FF) doesn't mention anything. And, if FF selectively blocks addons for which a Debian package is available, that doesn't seem to apply since there are no such packages. There are some selenium packages, but not as a FF extension. Any ideas? Thanks, Ross DIAGNOSTICS The FF console log shows Events to handle the installation initialized.
