Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

I have been having a problem for weeks with Firefox where it keeps resetting my default search engine to Yahoo. I tried a lot of things, including looking through all my extensions for anything untoward and most recently refreshing Firefox. The problem remains active. I would really like to not have to keep resetting my search engine every day.

Post-refresh, I find that Firefox is opening new tabs from links on pages I visit. That one is a REAL pain to deal with. It seems to kick in more on commercial pages than other pages. How do I stop that one? I already appear to be clear of bad extensions and I already refreshed Firefox1

What is it with my default search engine constantly being changed behind my back? Is the Firefox update doing this? Is something else? Can't it be locked down so that only I can change it in the Settings menu? It really annoys me that I suddenly find I'm doing a google search when I, after research and deliberation, set the browser to search with DuckDuckGo.

I have been fixing dozens of problems with 140 ESR's GUI. Earlier today I fixed almost all of the problems with the search panel:

Except one: I do not know how to detect when the default search engine has changed. I need to know how to detect when the default search engine changes so I can update the favicon and placeholder text by recalling my gui_fixes_search_favicon() function in userChrome.js.

I'm an experienced web developer of 20+ years and would be grateful if someone could share their insight without the often "obligatory" cautionary tales 101 bit. Thank you in advance!
