It is possible you either have a problem with your profile, or an extension is causing this.

Try reading How to fix preferences that won't save. If that doesn't help, will tabs stay on bottom in Diagnose Firefox issues using Troubleshoot Mode

It is not a bug. The developers have chosen to force everyone into using this ******* arrangement. It would not surprise me at all that a firefox developer made it so that no matter how you have it set, it reverts to the #1 ******* position.

This is seriously getting as bad as Microsoft's Ribbons. I also would not be surprised to learn that Microsoft has hired developers to work on Firefox. It makes sense.

With Aurora 15, there's not even any option to move the tabs. It's complete and utter bullshit. Tabs should signify change of content, and since the controls do not change, there is no reason for the controls to be "in" the tabs.

moderator - If you don't have anything positive to contribute which helps the "owner" of a question thread, please refrain from posting anything at all. If you need help with a problem of your own, please start your own question thread and ask for help. Otherwise you are interfering with the support process for the "owner" of this thread and that won't be tolerated here.

In Firefox 15+ you will have to toggle the browser.tabs.onTop pref directly on the about:config page because you can't do it via View > Toolbars or Firefox > Options.

I have to agree with AeSix. After spending hours trying to configure FF15 I am ready to delete the whole mess and go to Chrome.

Okay, Mr HotShot moderator, here's a question for you: Why did the alleged developers decide to remove the tab position option from the setup menu? Why is it necessary to dig into the config guts of FF to make the change? And, how about you make a positive contribution by providing real answers, instead of just throwing your weight around like a LA cop.

I would dump the whole overbloated mess that Firefox has become, if I wasn't developing web sites and needed it for testing. And here's another question: Why does Firefox display pages so differently from IE and Chrome?

First, if you're trying to be helpful - what is the answer?

Second, If you had read the question you might have noticed it was directed at the "moderator" and the programmers, NOT the volunteers.

Third, professionals must use all three major browsers to check the appearance of their web pages. Failure to do so results in amateurish pages.

And finally, If Mozilla is so responsive to bugs and problems, why is Firefox lagging behind in 3rd place? Is it because Mozilla programmers believe they can do no wrong, or is it because volunteer forums seldom produce meaningful answers, and simply resort to name-calling.

I have posed the questions. If you don't have the answers don't bother replying.
