Firefox 3 is a vintage version of the Firefox web browser that works well on older computers. It's a good choice for those who want to use a previous version for web surfing too.

Though Firefox is a popular web browser, some users dislike the way it automatically downloads new updates. Once you close your window and reopen the browser, you can only use the new version. Some updates may cause the browser to run slowly or limit the number of tabs that you can use at the same time. With Firefox 3, you can restore your browser to an older version.

The main issue with this browser is that it doesn't have very many features. Using it will remind you why so many people like the modern versions of Firefox. It has a fairly basic look and lacks some of the add-ons and plug-ins that you might use on a newly updated version. Those who want something simple that is easy to use though will prefer this version to a newer one.

Its design features a large address bar across the top of the page with a search bar to the right. The address bar will keep track of the sites that you visit most frequently and keep those pages listed. Clicking the arrow button at the end of the bar lets you select one of those sites. You can also enter a letter or word in the bar and view all pages related to that letter/word from your browsing past.

With the search bar, you can select the search engine that you want to use. Though it comes with Google set as your default, you can pick another. Entering a term in this bar will bring up a list of related search terms that you can choose from based on what you want to find. Firefox 3 includes a Most Visited button just beneath the address bar too.

The options menu gives you access to all the settings and features that you need. You can choose what happens when you download a file, including whether the file should open and where your computer saves a copy. This menu lets you change when the browser opens and what page it loads first as well as whether you want to set it as your default browser.

While Firefox 3 lacks some of the advanced settings found on modern versions, it's still a good option for older computers and any device with an older operating system because it runs smoothly and quickly.
