Steps how to reproduce with German Seamonkey 2.33.B1 Build 20150223174142 on German WIN7 64bit: 1. In Browser: Menu 'Tools ► Add-ons Manager' » "about:addons" appears 2. Menu 'File ► New ► Browser Window' 3. Menu 'Tools ► Add-ons Manager' » "about:addons" appears 4. In "Extensions" Into "Search all Add-ons" type "Price Grabber Search" ► Click Find-magnifier » few (2) hits will appear, (make sure that "Available Add-ons" is active, not "my Add-ons"), but not "Price Grabber Search" 5. click hyperlink at bottom of list "See all 912 results" » "Price Grabber Search" will be showd at top of the list as expected (Category all Add-ons, works with Seamonkey on all systems, all tags) 6. Try again in about:addons with "forecastfox" » many hits will appear, (make sure that "Available Add-ons" is active, not "my Add-ons"), but not "forecastfox" (but will work fine in "all results" 6. Try again in about:addons with "WOT" » many hits will appear, (make sure that "Available Add-ons" is active, not "my Add-ons"), but not "WOT" (but will work fine in "all results", "WOT Scorecard German Editon" shown on top of the list, but not WOT, (what without conversion only works with Firefox) a) "Download YouTube Videos as MP4" will be found on "about:addons", also "Speed Dial" b) For me it is unpredictable whether search in "about:addons" will be correct or not c) My suspect: something with filter rules (Seamonkey only of whatever) works wrong on "about:addons", but correctly on addons Website d) probably Firefox also affected, but results are different to Seamonkey, here some more research will be required.

Can I agree. Stand here exactly so.

Confirmed for Various OS at de.comm.software.mozilla.misc under "SM: Bugs bestätigen 2015-02 -- Bug 1070707 - Rueckgaengig zerstoert Texte "

This seems to work much better in FF: Search for "Show Password" In SM: - Show Password on Input - Password Tags - Last Pass - Xmarks Sync - Saved Password editor In FF: - Show Password on Input - Show Password 1.7 - Show Password Field - Show Keyword - Password Tags 2.1.5 BUT: What if the problem is related to a filter that will allow only SM compatible add-ons as search hits? I did not check this suspect, may be I will find the time later. That would be be a real Problem for a fix for "Bug 1145026 - AMO Add-On-Descriptions: Add link function leading to SeaMonkey add-on-converter and filling URL input pane"

I wonder whether there might be a relation to "Bug 1162864 - Add-on find results from speech balloon not found in final search results"
