In Firefox I often open logs from our CI server. Usually these have few hundred kB, but sometimes these can be up to several gigabytes in size. In this case, Firefox gets stuck (all tabs) and I have to wait few minutes until it processes the Back button press.
Naturally, I don't want to read through such pages (I rather ssh to the server and read them using better tool such as less). The server may not properly inform about the page size in headers, the logs are updated via AJAX when the test is running.
Is there any setting/plugin which would block downloading/rendering the pages which are over certain size/after timeout? Or warning me that the page is pretty large, if it can't process it in chunks.
