+- update to Thunderbird 45.7.0
+  * Message preview pane non-functional after IMAP folder was renamed
+    or moved
+  * "Move To" button on "Search Messages" panel not working
+  * Message sent to "undisclosed recipients" shows no recipient
+    (non-functional since Thunderbird version 38)
+  * Security updates from MFSA 2017-03 (Gecko 45.7.0) boo#1021991.
+    In general, these flaws cannot be exploited through email in
+    Thunderbird because scripting is disabled when reading mail,
+    but are potentially risks in browser or browser-like contexts:
+    CVE-2017-5375: Excessive JIT code allocation allows bypass of
+                   ASLR and DEP (bmo#1325200, boo#1021814)
+    CVE-2017-5376: Use-after-free in XSL (bmo#1311687, boo#1021817)
+    CVE-2017-5378: Pointer and frame data leakage of Javascript objects
+                   (bmo#1312001, bmo#1330769, boo#1021818)
+    CVE-2017-5380: Potential use-after-free during DOM manipulations
+                   (bmo#1322107, boo#1021819)
+    CVE-2017-5390: Insecure communication methods in Developer Tools
+                   JSON viewer (bmo#1297361, boo#1021820)
+    CVE-2017-5396: Use-after-free with Media Decoder
+                   (bmo#1329403, boo#1021821)
+    CVE-2017-5383: Location bar spoofing with unicode characters
+                   (bmo#1323338, bmo#1324716, boo#1021822)
+    CVE-2017-5373: Memory safety bugs fixed in Thunderbird 45.7
+                   (boo#1021824)
