Summary: String are not properly counted in RDM while search with Find Option → Strings are not properly counted in RDM while search with Find Option
I used mozregression to find a regression range here, although, I'm not entirely sure if this is very accurate. I encountered some issues when tried to bisect this bug. You can see here the results:

Based on the pushlog, looks like the following bug has the changes which introduced the regression: Bug  Bug 1240594. If you have any questions please let me know.
Keywords: regression
Bug 1240896 seems like a much more likely of a culprit given that regression range.

Yes, I would guess something like bug 1240896 is probably right.

However, I can't seem to reproduce the issue.  I think I am always seeing the correct count.

Ciprian, could you make a screencast of your test?
Flags: needinfo?(jryans) → needinfo?(ciprian.georgiu)
I forgot to add that you need to search through strings with "Find the previous occurrence of the phrases" and "Find the next occurrence of the phrases" buttons in order to reproduce it. 

As you can see in the screencast when I first enter into RDM and search through strings it displays 1 of 52 matches then goes to 2 of 52 matches as I click on the next button an so on.

But, when I close the RDM and open it again, then search for a string, it shows 7 of 52 matches even if I click on the next or previous button. Also, if I search for another string I can see the exact numbers (seems that strings are no longer counted). Hope it's more clear now.

Does this info helped you J.Ryan, to reproduce this issue? you can see here the screencast:

After a high level investigation, it looks like the find bar gets disconnected from the browser, so it's no longer receiving status updates correctly.

Search count looks correct now, but the string in the search field gets reseted on RDM toggle?

Good call, I sprinkled some more tweaks to preserve the search string too.

I managed to reproduce this issue on Firefox 53.0a1 (2016-11-17), under Windows 10x64.
The issue is no longer reproducible on Firefox 53.0a1 (2016-12-04).
I'm marking this issue Verified Fixed, but I'm not removing the qe-verify + flag, in order to see if this fix will be applied to 52.0a2 build as well.

Tests were performed under Windows 10x64, Mac OS X 10.9.5, Ubuntu 16.04x64
