The code for which i need to write event based rule is as follows.
<div class="search-result-message-subject"> <h2 class="lia-message-subject"> <div style="display: none;" class="lia-search-source">1</div><a class="lia-link-navigation lia-message-read" id="topicMessageLink" href="https://forums.adobe.com/t5/Tech-OnTap-Editions/August-Tech-OnTap-Newsletter-here-s-what-you-ll-find-insde/ta-p/397" data-ntap-position="1" data-ntap-keyword="ontap">August Tech <span class="lia-search-match-lithium">OnTap</span> Newsletter - here's what you'll find insde</a></h2> <span class="lia-message-author"> by <span class="UserName lia-user-name lia-user-rank-Community-Manager"> <a class="lia-link-navigation lia-page-link lia-user-name-link" style="" target="_self" id="link_33" href="https://forums.adobe.com/t5/user/viewprofilepage/user-id/25"><span class="login-bold">JonW</span></a> </span> in <a class="lia-link-navigation search-board-link" id="link_34" href="https://forums.adobe.com/t5/Tech-OnTap-Editions/tkb-p/tech-ontap-editions">Tech OnTap Editions</a> </span> </div>
This section of code repeats with the anchor tag ID changes to id="topicMessageLink_01".
So my event rule is set as selector= div.search-result-message-subject a and I have manually assigned the property "ID" as topicMessageLink. (as regular expression) This works fine in chrome but it doesn't work in firefox. Please help.
