Mozilla has introduced a new feature in the latest nightly build of Firefox that will enables users to select a seperate search engine for browsing while in private mode. This simply means that, you can have different search engines for normal mode and private mode.
This new Firefox feature seems to be inspired from Vivaldi browser, which uses DuckDuckGo as the default search engine in private mode.
How To Enable Private Search Engine on Firefox Nightly
It is disabled by default and you will have to make a couple of changes in the about:config to enable it.
Tried enabling the feature on Firefox Nightly version 71.0a1 (2019-10-03) (64-bit) and it worked just fine. If you’re interested to try out the feature on Firefox Nightly, follow the below steps.
1. Download and open the latest version of Firefox Nightly and go to about:config.
2. In the search box that appears now, paste the commands mentioned below one by one and set the value to true.
3. Now, go to Options -> Search -> Default Search Engine. From the drop-down list that appears below “Choose the default search engine to use in Private Windows”, pick the search engine you would like to use in private mode.
Currently, the browser lets you choose from Google, Bing, Amazon, DuckDuckGo, eBay, Twitter, and Wikipedia.
There’s still have the option to use the same search engine on both modes if you check the “Use this search engine in Private Windows” option.
Now that Firefox nightly has gained support for this feature, there is a solid chance for it to be enabled by default on the next stable build of Firefox unless any major issue crops up with this implementation. I hope you are excited to use this feature on your Firefox? Share your thought and experience with us in the comments.
