Editors' Review


Windows 10 introduced a different way of assigning default programs that requires a few more clicks and greater familiarity with the operating system's interface. Mozilla has responded with Firefox for Windows 10, which features a more streamlined Firefox installation, some visual tweaks, and a more secure add-on development process.


Add-on certification: Mozilla is attempting to make its add-ons safer by introducing certification. Developers must now adhere to a set of standards if they want to continue offering their add-ons. This standardization should reduce malicious hacks (not that there were many to begin with).

Search box utility: To the right of the address bar is a box that takes search queries. The advantage over Chrome is that you can search sites like IMDb, Amazon, and Wikipedia directly, without having to load them (or Google.com) first. This is helpful if you have a spotty connection or low data caps, or if you don't want Google logging your searches.

Smooth options navigation: Chrome bunches its settings onto one page, with small fonts and an inconsistent mix of buttons, links, and checkboxes. By contrast, Firefox's settings are cleanly categorized and subcategorized with tabs and a left-hand pane. When you want more explanation for what a setting does, just click the questi0n mark box in the lower right of the option page.

Enhanced password security: Unlike Chrome, passwords you save in Firefox are encrypted, and you can protect them with a master password. This function does not transmit your passwords into a cloud storage system, unless you want to use Firefox Sync, which is optional and can operate alongside Firefox's local password storage.

Smoother scrolling: Whether you're scrolling with a mouse wheel, the arrow keys, or the Page Up/Page Down keys, Firefox moves the webpage up and down with a gliding action that makes it easier to track how you're moving on the page. It's not as slick as the scroll in Internet Explorer 11 or Microsoft Edge, but it's better than Chrome's jumpy technique.


Australis could still use a few tweaks: The Australis redesign in April 2014 changed every aspect of Firefox's interface, and not all of it for the better. There's still no way to resize buttons, the icons in the upper right are monochromatic and thus more difficult to distinguish, and the original main menu button had a more compact menu. Thankfully, you can get most of the old functionality back with the free Classic Theme Restorer add-on.

Underwhelming add-on discovery: Comparing Mozilla's add-on website to Google's, Google delivers more relevant search results and more visual aids showing how the add-on looks and what it does.

Bottom Line

Firefox for Windows 10 isn't a whole lot different from the version that we reviewed in April 2014, but it's still an excellent browser that performs well against the competition, even exceeding it in a few areas.

"No improvements, increased timeouts"

August 31, 2015  |  By lmonteros

 |  Version: Mozilla Firefox 40.0.3


Same old Firefox, nothing new to learn.


Timeouts and non-connections increased


Why issue a new release when nothing has really changed? Or better, why does Firefox issue so many releases to fix bugs or security? In this recent release, I am getting timeouts on a site I visit every day which has cookies already loaded, and non-connection on the secure, trusted site NASA.gov. I'm afraid this kind of thing is SOP with Mozilla releases.

"I was forced to return to 31 soon."

I wrote all articles to Summary.


I wrote all articles to Summary.


I updated Firefox ESR from 31 to 38. But, I was forced to return to 31 soon. Because Firefox ESR 38 had many malfunctions. Additionally, Firefox ESR 38 had many inconvenient points. Firefox ESR 38 disappointed me. I hope that Firefox developers never upgrade Firefox. I will write detail problems and troubles in below.

When I updated it, all icons of bookmarks were vanished.

When I updated it, all information of [already-read addresses (displayed purple)] were reset. So, all link addresses became blue.

[Menu bar > Tool > Apps] were added. It is very obstructive.

And, Firefox ESR 38 has many other malfunctions and troubles.

Therefore, I rewound to Firefox ESR 31. I recommend for you to remain Firefox ESR 31 strongly.
