 I don't know if this coincided with https-everywhere being updated to
 4.0development.10 - in fact I don't remember for sure whether I was on the
 stable or development branch prior to this - but Google Mail in particular
 has become a lot slower in the last few days.

 In more detail:
 Extensions: Adblock Plus, Cookie Monster, https-everywhere, NoScript,
 RequestPolicy, SQLite Manager, Ubuntu Firefox Modifications, View
 Dependencies, Web Developer (all enabled)

 Steps to reproduce:

 Check that all of the above extensions are present and enabled.

 Navigate to https://mail.google.com. There is quite a long delay before
 the page has fully loaded.

 Temporarily allow google.com to execute scripts and temporarily allow
 google.com cookies. This leads to a further delay - which I should have
 timed - but I do know that after temporarily allowing requests from
 google.com to gstatic.com in RequestPolicy, there is another delay, just
 as long as the first, before the page is rendered. Most of this is spent
 "connecting".

 There may be further delays in Gmail, but after a while they all seem to
 be sorted. Possibly these delays are related to the first time each
 certificate is encountered.

 However, if I first disable https-everywhere, there are no such delays.

 Navigate to other sites, such as nationalrail.co.uk. These are also
 noticeably slower in the last few days - unless https-everywhere is
 disabled. I've had https-everywhere installed for a couple of years now,
 and I think that things were still fine for a while after the last update
 on August 16.

 Finally, close the browser. I have it set to clear history when Firefox
 exits, and to clear everything except site preferences, however far back.
 If https-everywhere is enabled, System Monitor shows the activity
 resulting from this to take much longer than usual, as if more information
 is being deleted than would otherwise have been the case.

 Does anyone have any idea where the problem might lie, and if there's
 likely to be a less radical workaround than disabling https-everywhere
 altogether?
