I solved it now

Yes, you do the first floating and other horizontalmanager scrolling.

but in the constructor of your form, you must specify this too

  • I need to open the web site even in two separate tabs. Since I've upgraded to Firefox 6 when I try to open the web page in a new tab in the list in the drop down in the address window it gives that the opportunity to move to the already open tab.

    When I get off the fall from the address window, rather than display the URL of the Web site I want to open in a second tab says "switch to the tab '. But I don't want to move to the tab - I want to open a second tab on the same URL. If I want to open it a second time, I have to manually enter the address. Is it possible to turn off this option so that I can open the second tab by using the same address in the drop-down menu? I was always able to do this with the previous versions of Firefox.

  • cannot move tabs from the bookmarks menu, if I close menu bm and reopen, I can drag tabs to it temporarily, but it will fail again soon.

    Title pretty much everything said. I can't drag to the menu bookmark tabs without closing and re-opening then menu bm. Then it will last for a while that I can drag the tabs to the menu but at some point I can no longer drag the tabs. When I drag a tab, I get a little picture of the tab url page but no line that shows where the tab can be moved.

    A corollary of this problem, I think, is that bookmarks bar won't remember from one day to the next the changes I made. He remembered the changes through a reboot and so far, for the rest of the day. But the next morning, the bookmarks are back to what they were, just confused upward.

    I've deleted and reinstalled FF, I refreshed it, I took ALL the Add-ons to the wide (including one I use all the time roboform) and the problem persisted for several days. I don't remember when exactly it started, but a week ago, everything was fine, I was not using problem and one day I could no longer be synchronized with xmarks xmarks and roboform and my favorites were all messed up.

    You can check for problems with the database places.sqlite file in the Firefox profile folder.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem.

  • Tab of the menu in the Menu bar does not open in Firefox 38.0.1.

    When I try to open the Menu tab in the Menu bar, nothing happens. If something when I click Menu a very small square appears under the underlined M, then disappears when I click on it again. All the other tabs on the Menu bar of the HelpFile works just fine. I uninstalled Firefox 38.0.1 the reinstalled again and the problem persist. I even went back to 37.0.2 but the problem persists even if it didn't happen when I was running 37.0.2 before installing 38.0.1. It is worth noting that I've actually upgraded to 38.0.1 17/05/2015 and everything has worked fine until today.

    You have a "Community Toolbar" extension installed? Which has been reported by other users of Mac as affecting the new tab feature in Firefox 30.

  • TabGroups Manager use/uninstall deleted view - toolbars - tabs on the top menu.

    After using the TabGroups Manager addon for a short period, I decided to remove again. One of the options that it allows him to use tabs on the high function, I was using. He puts his own groups of toolbar in the title bar, but it seems buggy, so I removed it, with tabs on top still operational. I had been using it via the main menu, by using Alt-V-T-T. After you remove TabGroups Manager according to the normal procedure, from the extensions page and restart, I realized that I had tabs on top and went to restore it, but the element is missing from the menu. I don't know any other way to change this, but the biggest concern is that the menu items have been removed at some point. Please could you tell me what may have caused this and how to restore the option.

    The status bar is no longer used in current Firefox releases and is replaced by the add-on bar (view > toolbars).

    Current versions of Firefox only show the menu entry "Tabs" at the top menu "view > toolbars" and "Firefox > Options ' and in the shortcut menus toolbar if the tabs are not in the default position on the top.

    If the notches located on the top and the menu entry is not available and you want to move the tabs under the navigation toolbar, then you have to toggle the pref browser.tabs.onTop false on the subject: config page.
    A restart of Firefox is necessary for updating the menu entry to display or remove.

    Note that this pref will no longer effect when the code Australis lands on the output channel (which will be in Firefox 29,0).

    Some menu entries in the main menu bar are hidden if you are using the mouse and only appear if you use the keyboard to open the menu.

    Some entries in the View menu and history have been deleted to clean up the UI, because studies showed that it was low-use items.

    On Windows and Linux, these were already hidden when serve you the mouse to enter the bar of menus and only appeared when you used the keyboard.

    You can click on the button Home (far-right on the Navigation bar) or the keyboard (Alt/Option + Home).

    You can find backward, forward and reload from the context menu in the navigation area or the use of the buttons on the Navigation toolbar.

    Thanks for posting the details of your system. I'm skeptical about the "CompTool0234 Community Toolbar". Could you disable some add-ons and see if that helps.

    On this tab:

    Firefox orange (or the Tools menu) button > addons > Plugins category

    Disable «Conduit Plugin»

    On this tab:

    Firefox orange (or the Tools menu) button > addons > Extensions category

    Disable the CompTool0234 community toolbar.

    Then very probably a link will appear to restart Firefox to make the change. Does make a difference?

  • Tabs at the top of the page option does not appear in the menu when I control-click on a blank section of the tab strip in Firefox MacBook on 15.
