Hi,

Please check if this happens in Safe Mode.

Uninstalling Add-ons

Uninstalling Toolbars

Safe mode disables the installed Extensions, and themes (Appearance) in Tools (Alt + T) > Add-ons. Hardware acceleration is also temporarily disabled - the manual setting is Tools > Options > Advanced > General > Use hardware acceleration when available. Options > Advanced. All these settings/add-ons can also be individually or collectively disabled/enabled/changed in Firefox normal mode to check if an extension, theme or hardware acceleration is causing issues.

Options

If the page is not already bookmarked, clicking once on the star in the location bar bookmarks your page and saves it under the Unsorted Bookmarks location. After the page is already bookmarked the Edit This Bookmark dialog pops up. This is the right behavior and this is what happens on my machine. What OS and Firefox version are you using?

I think it's not in Safe Mode, because all addons works well. Yesterday it was still well, and no addons installed before the problem happened.

Yes, so this is wrong behaviour. I use windows7 ultimate 64bit, waterfox 10.0.2. And it works well yesterday.

oh, an addon causes the problem. I've solve it. Thanks Vivek.Wilfred and simona.badau.
