New URLs possible from current accounts.

@Sven

For the last 2 versions when I run a new project – new (removes the cache from the target URL, removes the history, new emails, about 12,000 UNIQUE popups)

When I start ser I see the following:

1. This message appears all the time.

2. The list of 12000 gets about 120000 and lengthens.

3. After about 30 minutes, the remaining target URLs contain a lot of duplicates.

So,

1. The list is almost impossible to complete. Especially if you have 100 projects.
2. Too much CPU for all operations because the list contains thousands of duplicates. (AMD FX-8350 @ 4.5 Ghz)

I've been using it for about 3-4 years, so I think it's definitely a bug of the latest versions.

Can you check it?

Thanks in advance,
