There are some possible workarounds for Saved Searches.
You could try reaching your searches through your Feed page, then click on the number of searches at the top. You should see a multi-column text list of your saved searches. If you do not see the drop-down when you click on the number, try disabling your ad blocker on just that page.
Alternatively, you may be able to use the element hiding feature of an ad blocker to specifically block the large image tiles on the new Saved Searches page.
Try adding this rule under custom rules in Ad Block or Ad Block Plus:
