Most users prefer to utilize browsers that they can edit the look and feel of, and change in other ways, to suit their preferences.

The most customizable browsers include numerous built-in customization options that enable users to configure start pages, web page fonts, tab bars, URL address bars, appearance, themes, and even keyboard shortcuts.

Aside from built-in settings, the best customizable browsers have vast extensions (or add-ons) and theme repositories.

Users can add a wide variety of additional extensions to some browsers that transform their start pages and add new customization options and features to them.

What are the best customizable web browsers?

That update made Firefox a faster and more system-resource efficient browser with an enhanced web engine.

Fox includes a Customize Firefox tab from which users can drag and drop button options to and from the browser’s toolbar. There you can select four different default themes, change the UI’s density, and change the position of the URL address bar.

Firefox’s Options tab includes more customization settings. There you can further configure the browser’s address bar, New Tab page content, and tabs.

The Options tab also includes extensive settings for customizing fonts and text/background color schemes for pages.

Edge has become one of the more customizable web browsers since Microsoft converted it to Chromium code.

Now Chromium Edge has an enhanced UI design, new features, a massive extension repository, downloadable themes, a revamped New Tab page, and more customization settings.

Edge’s New Tab page is more customizable than those in Firefox and Google Chrome. Its users can select three pre-defined page layouts or set up custom ones with their own wallpapers. It also includes feed users can personalize to suit their content preferences.

Furthermore, Edge’s Settings tab includes a Dark option that turns the whole browser black. Users can toggle toolbar buttons on or off and customize page fonts via that tab. Thus we regarded it as one of the best customizable browser.

The Settings tab in Edge also includes a good range of site permission settings with which you can block or allow webpage content and features.

If you remember, the old Edge only had a small number of extensions, but all that has changed. Now Chromium Edge users can add all the extensions in the Chrome Web Store to this browser to customize it.
