Prevents LexisAdvance from hanging in Chrome with more than 6 open tabs
LexisAdvance hangs in Chrome when more than 6 tabs are open. This extension fixes the problem.
The hanging seems to be caused by a bug in the LexisAdvance server that prevents WebSockets and SSE from working. So, the client falls back to long-polling, which runs into Chrome's 6 connection-per-server limit.
This extension fixes the problem by blocking the long-polling URL.
