Home page slows Firefox to a crawl
Doing anything on the home page slows Firefox to a crawl. Yesterday, it was so bad that I got repeated alerts from Firefox that said "something on this page is slowing Firefox."
This issue has gotten far worse over time, to the point now that Yahoo is just not usable for most tasks and hasn't been for a couple of months. And the issue is limited to Yahoo--every other site works just fine in Firefox.
If you're trying to drive people to pay for your "plus" service to bypass the extreme slowdown (which I suspect is caused by the--no exaggeration--hundreds of ads that my adblocker blocks), it's not working. I'm using other services for most of my email and all of my news aggregation because Yahoo is slower than molasses rolling uphill in January.
Since you've already started writing ad copy under the guise of "articles," it's honestly better for you to keep doing that instead of driving users away because the site is so slow that it's unusable.
