Firefox Community Forum

I'm not sure what update it was but, new system so I had to go into setting and set things how I like. I cant remove options from additional search engines in settings. This used to be a normal feature. It is no longer one. I want to know how to remove them. Not just disable them, it is not the same. It's fine, If I have to manually recompile the browser to get this done. I just don't want them there. On version 155.0a1 on Arch Linux.

Any constructive help would be greatly appreciated.

How to get rid of BING setting on internet/Firefox

Contributor note: See also /questions/1595954 and /questions/1595955.

I'm running Windows 11 Pro on a desktop PC. I have used Firefox "Search by Image" many times and I haven't had a problem in the past. A few days ago the search failed for "some" images and now it fails for any and all images that I drag and drop into my browser. Important: It does work for images on the internet. My problem: (1) I drag and drop an image into my browser. (2) I right-click on the image. (3) I select "Search by Image". (4) I select a search engine. Absolutely nothing happens. I've tried with various images and various search engines. Still nothing happens. I don't think I'm doing anything different than I've always done. I haven't changed any settings in Firefox. Any ideas?

perhaps if you just had a few empty boxes so someone could write in the name of the search engine and firefox would know the complex URL's connected to the name of the search engine.............

After today's Firefox update (7/30/26), I can't activate DuckDuckGo search. When I type a search in the URL bar, if i select a bookmarked URL, it will launch the bookmarked URL. However, if I select a search query (ex. "sonicare toothbrush" in attached pic #1), it won't allow me to press enter to launch a search.

Under Settings, when I click on "Activate" DuckDuckGo search (attached pic #2), nothing happens.

I tried to use Firefox as my search engine but that didn't work so I re-downloaded DuckDuck, but the address bar say "search with google". I use to have DuckDuck but deleted it because I got tired of sites wanting to know my location. How do I get rid of that. I've tried all options in the settings file. I would prefer

This small but negatively impactful change is wrecking my workflow. Can anyone help with a userChrome.css fix to restore the old functionality?

Team Mozilla: *please* fix this likely unintended change in the next update.

I am trying to change my default search engine to Firefox and it isn't allowing me. What could be preventing this? and how do I get around it? Thank you in advance for your help.

I have Brave set as default search engine. I type in the address bar, hit enter, and always get a Brave screen with "404 Nothing matches the given URI". I downloaded the Brave browser and the problem goes away. But I prefer Firefox as my browser, so I'm hoping there is an easy fix to this.

Recent builds have changed the way that the user can direct queries to the various search engines that can be added (i.e. eBay, Wikipedia, IMDB etc) - to a new configuration that is awkward and forces more clicks.

Here is the method that currently allows reverting to the previous approach :

in about:config

Set string "browser.search.widget.new: to false

... and to delay automatic deletion of engines set "browser.search.widget.removeAfterDaysUnused" to thousands
