What's the homepage? Screenshot of the issue.

Hi, I'm not sure which one it is: (A) Tabs bar (usually at the top) You can usually close most tabs using right-click > Close tab. However, if it's a pinned (icon only) tab, you may need to Unpin it first. More info on pinned tabs: [[Pinned Tabs - keep favorite websites open and just a click away]]. (B) Bookmarks Toolbar (usually the lowest toolbar) If you find an unwanted bookmark, you usually can remove it using right-click > Delete bookmark. However, sometimes one of your add-ons will force you to have their bookmark. In that case, some cleanup may be needed. I'll list the steps for that below the line. (C) Built-in Firefox Home / new tab page For information on managing the contents of this page, see: [[Customize your New Tab page to hide or display content]]. ---- You can view, disable, and often remove unwanted or unknown extensions on the Add-ons page. Either: * click the Extensions button (puzzle piece) on the toolbar > Manage Extensions * Ctrl+Shift+a (Mac: Command+Shift+a) * "3-bar" menu button (or Tools menu) > Add-ons * type or paste '''about:addons''' in the address bar and press Enter/Return In the left column of the Add-ons page, click Extensions. On the right side, find the "Manage Your Extensions" heading. ''If there is at least one extension before the next heading -- "Recommended Extensions" -- please continue:'' Then cast a critical eye over the list below that heading. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything suspicious or that you just do not remember installing or why? If in doubt, disable (or remove). For your privacy and security, don't let mystery programs linger here. Any improvement? ''Note: Sometimes extensions can frustrate access to this page. In that case, first restart Firefox in its Troubleshot Mode and then try again.''
