Editors' Review


Mozilla's latest browser, Firefox 29, features the new Australis design, which adjusts the user interface, modernizing the look of tabs, menu layout, and toolbar. However, the new design also brings the pain of change: Users will have to adapt to rearrangements of core features.


New design: Firefox's new design is a bit Chrome-like, presenting menu options as large icons, similar to Chrome apps. The tabs have been cleaned up and look curvier and sleeker. Subtle animations make the Firefox experience slightly more interactive. For example, bookmarking a site triggers an animation of a star dropping into the bookmark icon.

Compatibility: Firefox 29 maintains compatibility with many older, popular extensions. The Australis interface has been around for a while for users who've been on the Beta and Aurora channels. Though many extensions are disabled by default, you'll find many old add-ons work with the new design.


Learning curve: You may be thrown off by the new UI. Things aren't where they used to be, which will likely cause problems for the millions of users who have become accustomed to a Firefox layout that hasn't changed much over a dozen versions.

Extension updates: Though many extensions work, some add-ons will likely break, especially toolbars and theme packs. Stable channel users will have to wait for newer versions of many add-ons to be rolled out in the coming months. Because Australis delivers a major visual overhaul, many themes will break and need updating to reflect the new interface.

Bottom Line

Mozilla has given its interface an impressive redesign, making Firefox a modern experience across all platforms, including mobile. Mozilla argues that the visual upgrades and interface changes will ultimately outweigh the near-term hiccups that users will face. Though Australis begins paving the way for Firefox OS, only time will tell how receptive users will be. That said, everything under the hood is still the Firefox we know and love: an open-source beast of a browser that champions customization and speedy load times.

"Reasonable as a substitute fro the old Opera"

January 24, 2015  |  By howardferns

 |  Version: Mozilla Firefox 35.0


Extremely configurable, I've been able to make it almost exactly the same appearance as my beloved Opera 12.17 which is no longer downloadable for a new pc. The tabs with rounded corners look nicer than the old Opera's square ones. The Sync feature to share settings and preferences between computers appears to work.


I don't care what others say, I find It a fraction slower than Opera 12.17 was, particularly on my netbook. Web pages take longer to load fully, while vertical scrolling is slow and jerky. A big annoyance was that I couldn't download files, it just locked the machine up. I realised this was something to do with Firefox but it took a bit of trial and error with the settings to cure it. (Go to Options > General and select 'Save files to' a place of your choice. That was originally the default but I had changed it to 'Always ask me where to save files' which did not work for me and is what caused the problem.)

"Ver 35 works for far"

January 21, 2015  |  By frank.enstein.56829446

 |  Version: Mozilla Firefox 35.0


* My user interface ok; I can work with. Not so different from FFX 28 in function
* Now able to stay up to date with bug fixes
* My Norton toolbar is back!


* Don't like the translucent tabs
* Don't like the IE style star (but easily removed)
* Still have the memory creep issue


Been using Firefox for years as my main browser, BUT did not upgrade from ver 28 last year b/c I do not like Chrome and was under the impression that Mozilla moved to a Chrome interface.

I just upgraded to Firefox 35 about 30 minutes ago! Seems to work for me far.

Mozilla seems to have created a sort of conjoined twins of the Firefox and Chrome UIs -- Old Firefox menus are there as far as I can see PLUS they added the Chrome-style 3-Line menu button in the upper right corner.

If I later find things missing in ver 35 that I need, I'll just grab the Classic Theme Restorer add-on.

If I do find issues in the future, I'll update my review.

I REALLY wish Mozilla would solve the memory creep issue present for years: FFX takes increased RAM with longer use during the day. I solve this issue now by closing FFX, disabling my Internet connection, restarting FFX, and then enabling the Internet. Procedure works well but an inconvenience.

Updated on Jan 23, 2015

UPDATED REVIEW, 24 HOURS LATER: I would now rate Firefox35 2.5 stars. The memory creep issue is even greater in the "new" Firefox vs the version 28 or prior. Firefox grabs an insane amount of RAM and quickly, no matter what I do. Makes it unusable for extended projects.

Solution options:
* Chrome? -- No, due to privacy/tracking issues
* Seamonkey -- too old UI
* Other Firefox clones - eg: Cyberfox -- No - same memory issues as Firefox itself
* IE? - Yes, will use as back-up browser (as before).

This browser is excellent so far! It is built on the same engine as Firefox BUT presents the pre-Firefox ver 29 user interface. All my Firefox plugins work as do nearly all of my extensions. Most importantly, memory issue is GONE!! No hogging and memory is released once tabs are closed! Pale Moon even has a migration tool that will quickly move your entire Firefox profile, bookmarks, plugins, etc over to Pale Moon with one click!

"Losing performance"

January 17, 2015

 |  Version: Mozilla Firefox 35.0


Add-on support is the best
Fastest browser
Great for people who hate advertisements
Does not spy on you unlike Chrome and Internet Explorer
Simple interface


Randomly will slow down
Flash Player (Adobe products) are terrible
Plugins crash


I know Flash Player isn't a product of Mozilla so this isn't their fault. But they rely heavily on horrible products from Adobe. Flash Player can easily become corrupted, crashes constantly, floods your usage and will slow down for no reason. Sadly I must say Chrome's built in video player is one million times better but I don't like using Chrome because Google loves spying on people and sending information about you to companies to throw advertisements in your face.

"It is the ONLY browser worth using."

January 15, 2015  |  By ganerd

 |  Version: Mozilla Firefox 35.0


LOVE the allowance of plug-ins like the spell-check, pop-up and ad blocker :)


Bombs occasionally but not NEAR as much as IE crashed.
