How can I hide bookmark toolbar after openning a web page (like chrome)?

Hi MECH01, welcome to Firefox, almost.

Some of these are do-able:

- There isn't bookmark auto hide in Firefox like chrome.

A lot of Chrome users like seeing the Bookmarks Toolbar only on the "new tab" page. This can be done by applying custom style rules to the bar (using a userChrome.css file). Since the rules vary depending on your language, I suggest checking the following site for how to do it:

Alternately, there might be an add-on to show bookmarks on the new tab page. I haven't searched for one of those recently.

- smooth scrolling is very very smooth and it's bothering.

You can turn that off on the Options page:

• Windows: "3-bar" menu button (or Tools menu) > Options
• Mac: "3-bar" menu button (or Firefox menu) > Preferences
• Linux: "3-bar" menu button (or Edit menu) > Preferences
• Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type scroll and Firefox should filter the page to the "Browsing" section. Here you can uncheck the box for:

"Use smooth scrolling"

- I think it's better to change the "mute tab" button with "duplicate tab."

Currently, Duplicate Tab is on the right-click context menu and there's no way to switch the two. If you never want to see the audio icon, you could hide it with a custom style rule.

There is this pref on the about:config page to hide this audio play icon.

• browser.tabs.showAudioPlayingIcon

Thanks for your answer But by switching it off, it gets very harsh Chrome has very optimized smooth scrolling

I think chrome has optimized any feature that makes difficult for everybody to leave it. There is nothing less or more in chrome.

There are a lot of general.smoothScroll prefs to set the way smooth scroll works, but I do not know what they are doing. See also:
