To get the toolbar back in Roblox Studio, you can try resetting the layout by going to the "View" tab in the menu bar and selecting "Reset Layout." If the toolbar is still missing, check if it’s hidden by clicking on "View" and ensuring that "Toolbox," "Explorer," and "Properties" are enabled. If these options are checked and the toolbar is still not visible, restarting Roblox Studio may also help restore it.
If your bookmarks have disappeared from the toolbar, try checking if the bookmarks toolbar is enabled in your browser's settings. In most browsers, you can right-click on the toolbar area and select "Bookmarks Toolbar" to turn it back on. Additionally, you can access your bookmarks through the browser menu (often found under "Bookmarks" or "Favorites") to see if they're still available. If they’re missing entirely, check if you have a backup or try restoring your browser settings.
It's possible you removed it from your toolbar. Simply edit your toolbars and put it back.

I am assuming you are using Microsoft Word 2003 or earlier since you seem to have troubles with a missing toolbar. You have mistakenly hid the Standard Toolbar that contains commands that include font size and color. You can bring back the Standard Toolbar by right-clicking on any other toolbars or the menu bar (where the File and Edit menus are ) and clicking "Standard" to bring it back.
The Header/Footer Toolbar is used the least often in PowePoint.
