Firefox users can now organize their search engines into folders, making it easier to find the information they’re looking for. The new feature is available in Firefox version 41 and up. To create a folder, open Firefox and click on the three lines in the top right corner of the browser window. From here, you can select “Add Bookmark,” “Add Folder,” or “Add Site.” Once you’ve created a folder, you can add your search engines by clicking on the “Search Engines” button and selecting from the list of options. You can also add a search engine by typing its name into the text field at the bottom of the window. If you want to remove an engine from your folder, simply select it and click on the “Remove” button. ..
The Organize Search Engines extension for Firefox will let you re-organize all the search engines into folders, which can be very useful for separating out the commonly used ones from the specialty searches.
After installation, you can go to “Manage Search Engines” to make your changes:
You’ll now see options to create folders and separators, just like in the manage bookmarks dialog. The one important thing to note here: You must use the OK button to close the dialog, or else your changes don’t seem to save.
Once you’ve organized into folders, you can change between them using the regular drop-down menu:
This extension is especially useful, however, if you also install the Context Search extension, which will let you right-click on a selection in the page and choose from the folders of search engines:
The one feature that didn’t work for me was the “Edit Keyword” option… I assume that part is incompatible with some other extension I’m running.
