Fixing Firefox: Wrong Title Address Bar Suggestion Issue

Introduction

Something went wrong somewhere, and you have tried clearing the entire browser data, except for your profile (since you would lose bookmarks and extensions). However, the issue still persists. When you type ""youtube.com"" in the address bar, you see a wrong title or suggestion. This article will help you understand the issue and provide a solution to fix it.

Understanding the Address Bar Suggestion Mechanism

Firefox's address bar uses a feature called "Location Bar & Address Autocomplete" to provide users with suggestions based on their browsing history, bookmarks, and open tabs. By default, Firefox also includes search suggestions from your preferred search engine. The feature allows users to quickly access their frequently visited websites.

Components Involved

The following components are involved in the address bar suggestion mechanism:

• Awesomebar: The address bar in Firefox, which suggests URLs based on users' browsing history and bookmarks.
• Places Database: A SQLite database where Firefox stores the browsing history and bookmarks.
• Form History Autofill: Firefox's feature that allows saving and filling out form data.
• Keyword.URL: A file located at ""%APPDATA%\Mozilla\Firefox\Profiles\\*.default\searchplugins\*.xml"" that relates keywords to search engines.
• Suggested Sites: A feature that allows users to crowdsource visited websites and share them with others.

Investigating the Issue

In order to determine the root cause of the issue, let's inspect each of the components involved in the address bar suggestion mechanism:

Awesomebar

First, let's ensure that the Awesomebar is enabled:

1. Go to ""about:config"" in the address bar and press ""Enter"".
2. Search for ""browser.urlbar.autocomplete.enabled"" in the search bar.
3. Make sure the value is set to ""true"" (double-click to toggle the value if necessary).

Places Database

Clear the browsing history and ensure that the Places database is not corrupted. To do so, follow these steps:

1. Press ""Ctrl+Shift+Del"" (Windows and Linux) or ""Cmd+Shift+Del"" (Mac) to open the ""Clear All History"" dialog.
2. Select ""Everything"" under ""Time range to clear"".
3. Check the box ""Browsing & Download History"" to clear history data.
4. Uncheck all other boxes to preserve your data.
5. Click ""Clear Now"" to clear the browsing history.

If the problem persists, let's check the integrity of the Places database:

1. Close Firefox.
2. Press ""Windows key + R"" in Windows, or open ""Terminal"" and type ""sqlite3"" in Linux or Mac.
3. In the ""sqlite3"" command line, enter ""< ```perl APPDATA>\Mozilla\Firefox\Profiles\*.default\places.sqlite"" (Windows) or ""~/Library/Application Support/Firefox/Profiles/*.default/places.sqlite"" (Mac) to open the Places database file.
4. Enter "".schema places"" and check if all the tables are present.
5. Enter ""PRAGMA integrity_check;"" and verify that there are no errors.

Form History Autofill

Clear the form history:

1. Press ""Ctrl+Shift+Del"" (Windows and Linux) or ""Cmd+Shift+Del"" (Mac) to open the ""Clear All History"" dialog.
2. Search for ""formdata"" in the search bar.
3. Check the box ""Form & Search History"" to clear form data.
4. Click ""Clear Now"" to clear the form history.

Keyword.URL

Verify that ""keyword.URL"" is not causing the issue:

1. Go to ""about:config"" in the address bar and press ""Enter"".
2. Search for ""browser.search.selectedEngine"" in the search bar.
3. Make a note of the value of ""browser.search.selectedEngine"" (e.g., ""Google"").
4. Search for ""browser.search.order.0"" in the search bar.
5. Make a note of the value (e.g., ""Yahoo"").
6. Go back to ""%APPDATA%\Mozilla\Firefox\Profiles\\*.default\searchplugins\*.xml"" (Windows) or ""~/Library/Application Support/Firefox/Profiles/*.default/searchplugins/" (Mac) and open the ".xml" file corresponding to the ""browser.search.order.0"" value (e.g., ""yahoo.xml"").
7. Search for ""name" and ""method" in the ".xml" file.
8. Verify that ""name"" is the correct name of the search engine and ""method"" is not ""keyword"" or ""unknown"".

Suggested Sites

Check if ""suggest.mysuggest.max_typed_history"" value is set appropriately. A large value might cause slower performance in the address bar:

1. Go to ""about:config"" in the address bar and press ""Enter"".
2. Search for ""suggest.mysuggest.max_typed_history"" in the search bar.
3. Verify that the value is set appropriately (e.g., value smaller than ""50"").

Solution: Reset Firefox to Default Settings

If the issue still persists after inspecting and fixing the issues mentioned above, you can reset Firefox to its default settings. Please note that this procedure removes all customizations and extensions, so make sure to back up your important data:

1. Press ""Alt+H"" (Windows and Linux) or ""Cmd+Shift+H"" (Mac) to open the ""Help"" menu.
2. Click ""Troubleshooting Information"" in the ""Help"" menu.
3. Click ""Refresh Firefox"" in the ""Troubleshooting Information"" page.
4. Click ""Refresh Firefox"" in the confirmation dialog to reset Firefox.
