I really hate this version and I want out of beta and out of 57. I have no clue how to get rid of it and install and earlier version like 53 maybe.

Hi inzaratha, if you want to switch from beta to stable, you can install Firefox 55 (or 56, depending when it's posted) from here:

https://www.mozilla.org/firefox/all/

Your Firefox reported itself to be the 64-bit version, but if anyone reading this is using the traditional 32-bit, please see the following article before switching: How to switch from 32-bit to 64-bit Firefox.

Regarding the specific issues, which you can come back to in 6 weeks:

I am a classic theme user and like my tabs on bottom.

Other users have posted custom style rules you can apply to your Firefox to reposition the tabs "on the bottom."

It also took away the edges around the tabs, like the square blocks around them and I find this really hard to see visually and really unworkable.

I'm sure a custom style rule also can add borders to the inactive tabs. I've been using a rule like that for many years now, but it needs to be updated for Firefox 57.

Also I had an additional bar with many things in it and it's gone now and none of those items are anywhere and they were data I needed.

Can you figure out what add-on is generating the additional bar and make a list of what is on it? This probably will need to move in Firefox 57, but it's going to be question of details.

You can 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 */

/* tabs on bottom */
#navigator-toolbox toolbar:not(#nav-bar):not(#toolbar-menubar) {-moz-box-ordinal-group:10}
#TabsToolbar {-moz-box-ordinal-group:1000!important}

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

• Help -> Troubleshooting Information -> Profile Directory:
  Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
• http://kb.mozillazine.org/Profile_folder_-_Firefox

• 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 the chrome folder (file name is case sensitive)
• paste the code in the userChrome.css file in the editor window
• 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
