Firefox 78 triggers search engine issue
Instead of fixing issues with Firefox, upgrade to a better browser: Opera
You deserve a better browser ! 350 million people use Opera daily, a fully-fledged navigation experience that comes with various built-in packages, enhanced resource consumption and great design.Here's what Opera can do:

  • Easy migration: use the Opera assistant to transfer exiting Firefox data, in just a few steps
  • Optimize resource usage: your RAM memory is used more efficiently than Firefox does
  • Enhanced privacy: free and unlimited VPN integrated
  • No ads: built-in Ad Blocker speeds up loading of pages and protects against data-mining
  • Download Opera

Once in a while a new browser version introduces one or two unwanted browsing issues, which is now the case with Firefox 78. The update brought a couple of impressive changes and features, such as accessibility tweaks, privacy protection, and more.

But it also broke search, making it impossible for affected users to use its integrated search engines like Google and Bing.

The good news is that Firefox 78.0.1, which goes live soon, will fix the search issue.

The Firefox 78 search bug

Shortly after the release of Firefox 78.0, a user reported a search issue that resulted from updating to the latest stable version of the browser.

All search engines are gone; list of one-click search engines is empty now. Auto complete in the address bar doesn’t work any longer. Search function on the start page doesn’t start a search any longer.

It appears that affected users no longer see any of the popular third-party search engines that Firefox offers by default. Usually, the browser lets users customize their search experience by adding their favorite search engines, for example, Amazon and DuckDuckGo.

Apart from the search issue, it seems that the browser’s address bar isn’t working any more. Moreover, the start page’s search function is defective right now.

Engineers at Firefox appear to have discovered the root cause of the issue. They’ve identified a couple of bugs that point to a malfunction in the local database that the search service utilizes.

The team started working to resolve the problem shortly after it made it to the Bugzilla forum.

For some reason the local database that we use to store some data is not working. Unfortunately our search service has just switched to using that local database, and as a result isn’t working properly.

Firefox 78.0.1 should address the search problem anytime now.
