Does the page load faster if you disable your ad blocker?
If so, there may be a particular filter causing the slowdown for you.
If you are using Ad Block Plus, try disabling your ABP filters in the Advanced section. If you are using Ad Block, try disabling your Anti-Circumvention filters in your filter list. If you have disabled either of those in the past, an update may have re-enabled them.
If that does not help, is there any difference if you use a different browser, or disable other add-ons?
