Why does anyone need to "explain" why Mozilla does anything?

"Tabs on bottom" was removed in Firefox 29 Australis. Users needed an extension like CTR or other to have "tabs on bottom" with Australis, but now those type extensions aren't allowed in Quantum.

With respect to say tabs on bottom is not allowed anymore does not answer my question. I would like to know WHY. What is the reason for this extremely popular choice to have tabs on bottom? was my question! Surely there must have been a reason to deny this simple option. Surely Mozilla should provide what many users are asking for or explain why not.

I believe you can restore tabs on bottom with userChrome.css. Please update to Firefox 62 as 56 is no longer safe to run.

I spent 5 days trying to get the .css folder with recommended code to work. As long as 56 works I am satisfied. I have Kaspersky Browser protection running.If version 56 gets overwritten again I go elsewhere.

No one has answered my question. i.e why has Firefox got rid of tabs on bottom? Giving a workaround is too complex for the layman! If answering the question is not an option please do not reply

removed

Tabs were moved on top as part of a redesign of Firefox several years ago (it makes more logical sense in the layout of the window) and was based on months of user research and design tweaking.

The option to move tabs back down was removed as the code behind it was complex, slow and unreliable.

Your kaspersky will not protect you from the security holes in old versions of software, so please update ASAP

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}

It is not that difficult to create userChrome.css if you have never used it.

The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder.

• https://support.mozilla.org/en-US/kb/use-troubleshooting-information-page-fix-firefox

You can find this button under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in this folder (name is all lowercase). In the chrome folder you need to create a text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted.

In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt file extension and you end up with a file named userChrome.css.txt. To avoid this you need to make sure to select "All files" in the dialog to save the file in the text editor using "Save File as".

You need to close and restart Firefox when you create or modify the userChrome.css file.

I did not knowingly update to latest version and I could get bookmarks or manage any of the ad-dons I had such as themes or tools that I had. I searched for at least 5 days to get any basic functionality that I had.

Over a long period (years) whenever an update was downloaded I lost some functionality due to previous ad-dons being incompatible. I have tried all the crap about creating a chrome folder and a userChrome.css file and then copying code into that file. I have totally given up and have reinstalled version 56 and regardless of of warnings that it is unsafe I have 2 security packages that seem to work. I am grateful that the Firefox volunteer forums have tried to help though I did manage to get my original question to Firefox them selves and got a sarcastic reply saying "We don't have to explain why we prefer tabs on top".

I no longer wish to use anything later than version 56 that is looking good and doing everything I need. CTR is listed as legend and if it gets dysfunctional I will go to chrome in its most basic entry level form. I find it very strange that Firefox ignores the flood of requests to resume the tabs on bottom. The tabs on top is to me akin to having a typical cardboard manual file with the physical tabs on the LEFT.
