After clicking okay, the browser window stays, I can click the menus, and the Windows buttons (Maximize, etc.) work. However, no response is generated when I click on any toolbar buttons or type anything in the location bar and press enter. Reproducible: Always Steps to Reproduce: 1. Install Mozilla Firebird 11/20 or 11/21 build for Win32 under WinXP SP1. Note that since there were no official Win32 builds for 11/20, this was an unofficial build from some forum, compiled with MSVC optimized for SSE. The 11/21 build, however, was official. The bug is the same whether the zipped or installer version is used. 2. Launch this version of Mozilla Firebird. 3. Actual Results: I received the error message "Error launching browser window: no XBL binding for browser" and the browser did not function. Expected Results: functioned normally
This is due to the change from bindings back to widgets (or is it the other way around, I can never remember). Themes/extensions need to be updated, or they will give this error. --> INVALID.
