Many websites do not work the same for both Internet Explorer and Mozilla Firefox, and what you see perfectly in another is careless or directly does not load some elements, and vice versa, this is also important for web designers who have to verify continuously if your web designs work in both browsers.
To solve this problem you can either have both browsers installed or have a tool like NetWorker 2.70 which is a browser that allows you to view the web in both browsers and visualize the possible differences in web design and programming between them.
This program only works for the NT, 2000 and XP version, if you want to install it on Windows 95, 98 or ME you must click this other link.
You can free download NetWorker and safe install the latest trial or new full version for Windows 10 (x32, 64 bit, 86) from the official site.
