Hi L17A, bank statements and menus sound like pages that might normally be in PDF format. Could you check your PDF setting on the Preferences page: [[View PDF files in Firefox]] Please note that you may see both "Preview in Firefox" -- the built-in viewer to read a preview of a PDF in a tab -- and "Use Preview (default)" -- for Apple's stand-alone PDF viewing application. If you are being forced to save files, this setting might be "Save File" rather than either of those. Was that the the problem? ---- Sometimes Firefox stops obeying those instructions, which can be caused by corruption in the settings file that stores download handling preferences. You can rename the file and have Firefox rebuild it. Here's how: Open your current Firefox settings (AKA Firefox profile) folder using either * "3-bar" menu button > "?" Help > Troubleshooting Information * (menu bar) Help > Troubleshooting Information * type or paste about:support in the address bar and press Enter In the first table on the page, on the Profile Folder row, click the "Show in Finder" button. If Finder highlights an icon with a semi-random name like a1b2c3d4.default, double-click it to display the contents of that profile folder. Leaving that window open, switch back to Firefox and Exit, either: * "3-bar" menu button > Exit/Quit * (menu bar) File > Exit (or Firefox > Quit) Pause while Firefox finishes its cleanup, then rename '''handlers.json''' to something like '''handlersOLD.json'''. If you see a file named '''mimeTypes.rdf''', rename that one to '''mimeTypesOLD.rdf'''. Start Firefox back up again. PDFs should be set back to "Preview in Firefox". Any improvement? ---- ''Sometimes an individual site will force PDFs to download rather than letting you view them in a tab. We can help you investigate any remaining site-specific problem, and suggest add-ons to work around them.''
