I was recently trying to view the TIFF version of the 1911 Encyclopedia Britannica: http://en.wikisource.org/w/index.php?title=User:Tim_Starling/ScanSet_TIFF_demo&vol=01&page=EB1A001 The U.S. Patent and Trademark Office website (uspto.gov) also uses the TIFF format. When I view the wikisource URL given above, I see a broken puzzle piece that lets me click to install a plugin that will display the image. This generates a "Plugin Finder Service" dialog window which says, "No suitable plugins were found. Unknown Plugin (image/tiff)". The only pointer the USPTO has for Linux users is to "plugger": http://www.uspto.gov/patft/help/images.htm So I installed mozplugger-1.7.3-3.1 (the official successor of "plugger") via yum, moved ~/.mozilla/pluginreg.dat and ~/.mozilla/firfox/pluginreg.dat aside, and restarted Firefox. /etc/mozpluggerrc is configured to try to use "display", "gqview", "gthumb", "xv", "sdtimage", and "qiv" to display tiffs. I also have "eog" installed, which could do the same job but is not listed. I have the first three installed, but I have the same problem viewing TIFFs. "about:plugins" gives no indication that mozplugger is correctly installed and functioning. Since I already have standard programs installed that are capable of displaying TIFFs, I would expect Firefox to handle them automatically. Preferably, they would just be displayed inline, but having a dialog box ask me if it's OK to display in an external application would also be an improvement. If additional software needs to be installed in order for Firefox to successfully display TIFFs, clearer instructions (or a URL that has clearer instructions) should be given when an undisplayable image is encountered. I don't know what those instructions would be, since I was unable to successfully enable integrated display of TIFFs in Firefox. mozplugger is listed at: http://plugindoc.mozdev.org/linux.html#MozPlugger It's marked as supporting Firefox, so I would have expected the official Fedora RPM to have worked. It would also be more user-friendly for the moving of pluginreg.dat to be handled automatically. I am running firefox-2.0.0.5-1.fc7.
At this point, we're going to only be taking security fixes and major stability fixes into this release of Fedora. However, we still want to ensure the bug is fixed in the next version. We'd appreciate if you could test Firefox 3, available at http://www.mozilla.com/en-US/firefox/all-beta.html or now shipping as the default in Fedora rawhide and provide feedback as to whether it still exists so we can file a ticket upstream to try to fix it in Firefox 3 before it is released.
Hmm, with firefix-2.0.0.12 and mozplugger-1.7.3-3.1, I see a grey box where I think the image would be, and can't right-click to open the image in an external application. If I load the TIF URL directly (the target of <img src="target">, I get a pop-up dialog that asks if I want to use EOG to view the image. I'll try testing in Firefox 3 and see what happens.
With Firefox 3 Beta 3, I am again seeing the broken puzzle piece and the "No suitable plugins were found. Unknown Plugin (image/tiff)" error. If I load the URL of the .TIF file directly, I get the dialog box that offers to display the image in eog. (This is with the .tar.bz2 file, not an RPM, since I'm running Fedora 8, not rawhide.)
I will probably blame mozplugger.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Confirmed that the issue still exists in Fedora 9 with the latest updates.
I can reproduce behaviour with Fedora 10.
i don't see the problem with latest mozplugger-1.12.1.
