To change browser settings, open the browser's settings page from its main menu and adjust the option you need. In Chrome and Edge, click the menu icon at the top-right (the three dots) and choose Settings, or type chrome://settings or edge://settings into the address bar. In Firefox, click the hamburger menu and choose Settings (about:preferences). On Safari for macOS, open the Safari menu and choose Settings, while on an iPhone or iPad you configure Safari from the device's Settings app. From there you can change your default search engine, homepage, privacy and permissions, downloads, autofill, extensions, and reset everything to defaults.
Chrome keeps every preference on a single, searchable settings page. The fastest way to find a specific option is to open Settings and type a keyword into the search box at the top.
Edge is built on the same Chromium engine as Chrome, so the layout will feel familiar, though the category names differ slightly. If you previously used Internet Explorer, note that Microsoft retired it on June 15, 2022, and all settings now live in Edge.
Firefox groups its preferences into a tabbed settings page. Older versions labeled this page "Options," but current releases call it "Settings."
Safari handles settings differently on each Apple platform. On a Mac, the controls live inside the browser; on an iPhone or iPad, they live in the device's Settings app instead.
On macOS:
On iPhone or iPad:
Although menus differ, the same set of preferences appears in every major browser. These are the ones most people want to adjust:
| Browser | Open settings via menu | Direct address |
|---|---|---|
| Chrome | Three-dot menu then Settings | chrome://settings |
| Microsoft Edge | Settings and more (…) then Settings | edge://settings |
| Firefox | Hamburger menu then Settings | about:preferences |
| Safari (macOS) | Safari menu then Settings | Command + comma |
| Safari (iOS / iPadOS) | Settings app then Apps then Safari | Not applicable |
Browser settings directly affect how a website renders and behaves, so testers often need a specific configuration. Changing settings by hand works for a quick manual check, but it does not scale and does not persist on a cloud grid, where each session runs on a fresh machine that is wiped when the session ends.
In automation, you apply browser preferences as capabilities or options instead of clicking through menus. Selenium exposes ChromeOptions, EdgeOptions, and FirefoxOptions for this, letting you set the language, downloads path, headless mode, permissions, and more before the browser launches. Running those configurations across a wide matrix of browsers and operating systems is exactly what a Cross Browser Testing Tools platform is built for, so you can confirm a setting behaves the same on Chrome, Edge, Firefox, and Safari without maintaining the machines yourself.
Most browsers have a reset option. In Chrome, open Settings and choose Reset settings then Restore settings to their original defaults. Edge offers the same under Reset settings. Firefox uses the Refresh Firefox button on the about:support page. Resetting returns the search engine, homepage, new tab page, and pinned tabs to defaults and disables extensions, but it keeps your bookmarks and saved passwords.
In Chrome, open Settings then Search engine and pick a new search engine used in the address bar. In Edge, go to Settings then Privacy, search, and services then Address bar and search. In Firefox, open Settings then Search. On Safari for macOS it is Safari then Settings then Search, and on an iPhone it is the Settings app then Safari then Search Engine.
Safari on iOS has no in-app settings menu. On iOS 18.2 and later, open the Settings app, tap Apps, then tap Safari. On iOS 18.1 and earlier, open the Settings app and tap Safari directly in the main list. From there you can change the default search engine, AutoFill, pop-up blocking, cross-site tracking, and clear history and website data.
Internet Explorer 11 was retired by Microsoft on June 15, 2022, and is permanently disabled on supported Windows versions, redirecting to Microsoft Edge. There is no longer a standalone Internet Explorer to configure. For legacy sites that need it, Edge includes an IE mode you can enable under Default browser. Otherwise, change your settings in Edge.
In Chrome and Edge, open Settings then site permissions (Site settings in Chrome, Cookies and site permissions in Edge), select JavaScript, and allow it. Firefox has no UI toggle, so type about:config in the address bar, accept the warning, search javascript.enabled, and set it to true. Safari for macOS exposes a JavaScript toggle under Safari then Settings then Advanced.
Cloud browser sessions usually run on a fresh, isolated machine that is wiped when the session ends, so any manual settings changes do not persist. To apply settings consistently in automated tests, set them through browser capabilities or options such as ChromeOptions, EdgeOptions, and FirefoxOptions instead of changing them by hand.
