Hey fediverse--

I recently made the switch from desktop Chrome to desktop #Firefox, which has mostly been fine, except for one problem:

Firefox stops bothering to answer AJAX requests in tabs pretty quickly, which makes my preferred webmail client--#Roundcube--FAR less functional under FF than it was under Chrome.

If left alone for a moment--or sometimes, even while typing an email--FF stops paying attention, further AJAX calls fail, and I'm forced to refresh the tab.

Anybody have any ideas?
