I recently installed the librejs add-on in Firefox (Debian, 45.9.0esr-1). I was able to browse a few websites and see some librejs summaries regarding their javascript content.

At this point I was already slightly confused that librejs's summary (when clicking on its toolbar icon) was not updated for a few sites (e.g. when browsing https://notabug.org/). But general browser usage was fine for some time.

Half an hour later all further website load operations failed as long as the librejs was enabled. Disabling the add-on immeadiately fixed this problematic behaviour. Re-enabling the add-on caused the failure again.

The developer console of Firefox showed that at least the response headers were retrieved. I cannot tell, if the document body was returned as well.

The problem was visible with http as well as https traffic.

A traffic dump with the target host via tcpdump showed that at least 20 packets were exchanged. The last packet was a response from the target host. No further requests seems to have been made by the browser. Thus this does not look like a timeout issue or a missing response from the target host.

Ticket 50551 (https://savannah.gnu.org/bugs/?50551) looks related. But I could rule this one out, since the problem persisted even when I removed "gzip" and "deflate" from the browser request header "Accept-Encoding" (see "about:config" -> "network.http.accept-encoding").

Also ticket 46300 (https://savannah.gnu.org/bugs/?46300) looks similar - but it is very unspecific. Thus it may be related to another problem.

I would be happy to use librejs when browsing the web.

Thank you for your time!
