You can look at the Classic Theme Restorer extension to restore some functionality that was lost with the arrival of the Australis style in Firefox 29.

• Classic Theme Restorer: https://addons.mozilla.org/firefox/addon/classicthemerestorer/

• You can check out the settings of the CTR extension via its Options/Preferences button on the "Firefox/Tools > Add-ons > Extensions" page.
• You can find extra toolbar buttons and more toolbar settings in Customize (3-bar Firefox menu button > Customize)

You can hide the "3-bar" Firefox menu button with code in userChrome.css if you do not want to use this button.

Add code to the userChrome.css file below the default @namespace line.

• http://kb.mozillazine.org/userChrome.css

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#PanelUI-button { display:none !important; }

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

• http://kb.mozillazine.org/Editing_configuration

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

• Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
• Use a plain text editor like Notepad to create a (new) userChrome.css file in this folder (the names are case sensitive)
• Paste the code in the userChrome.css file in the editor window and make sure that the userChrome.css file starts with the default @namespace line
• Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css. Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file

While a nice addon it doesn't seem to entirely revert it back to the older/better firefox GUI. I would rather have a way to truly go back to earlier versions where the problems of the modern don't even exist.

Hi!

Thank you for trying the new Firefox. We’re sorry that you’re unhappy with the new design. However, it's best if you don't downgrade because older versions have security weaknesses that the release build of Firefox does not have. Please try the recommendations from cor-el first.

If you are still dissatisfied with your Firefox, you can use the Install an older version of Firefox link to get more information about downgrading. Again, this is highly unrecommended because of the potential dangers to your security it presents.

I hope that solved your problem!

If it did, would you please choose this answer as your solution? It would help other Firefox users to find help on the forums faster and more efficiently. Thanks!

And of course, feel free to post back if you need more help!

Happy browsing!

cor-el I cant seem to get the code to work. I created a folder called chrome inside the only folder in the profile folder (C:\Users\Admin\AppData\Roaming\Mozilla\Firefox\Profiles\lq6xoyzr.default\chrome) I then made a userChrome.css file and pasted the code posted and nothing else into this file and resaved it. It remained a css file not a txt. I dont see any effects from this code and the button is still on the side. Did I miss a step?

Epicaleb Thanks I will use them if I cant get it where I want it.

Thanks to all who replied.

Epicaleb I went ahead and edited your post and included a link to the Install an older version of Firefox and removed the link to the FTP site. Just a formality.

Pockyninja You can use the link above to get to the same place but with more information on that in case you still decide to downgrade to a previous version.

I was able to use the code cor-el provided without a hitch. I think I know what you missed.

Did you save the .css file type as ALL FILES as opposed to the traditional .txt format? If you do this while adding userChrome.css it will become userChrome.css.txt and thus will not work. Make sure the file type is at All files and NOT .txt

Well I did figure out what was wrong with using his code but it was not the problem you expected. I also used the addon in the first post to revert the rest of the GUI to the older ways. Somehow the 2 don't work well together. Is there a way to get them both to work at the same time? This one https://addons.mozilla.org/firefox/addon/classicthemerestorer/
