User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1 Build ID: 20120713134347 Steps to reproduce: Add a local file:// page to SpeedDial. Actual results: access 404 When I edit this local dial,I find firefox auto insert http:// before file///. Then I delete http:// click ok,http:// auto inserted too. Expected results: Smart detect dial location,and never assume it is http.

By Speed Dial, do you mean the default New Tab page? I do not see an option for making a custom dial in Aurora 16.0a2 (23-08-2012) on Windows

Yeah,the default New Tab page. Sorry,I am not sure the right version,it seems like the version I choose is wrong. My firefox version is: updated 15.0 (release)

Can you explain how you added a custom dial? I cannot seem to find a way to do that myself.

Firstly,open the new default tabpage. 1.Move cusor to one dial,this dial become focused.Notice left corner,you can see an edit icon. 2.Click the edit icon,then edit layout become popup. 3.Type my link into location input,and click add.

All I see on a dial is the Pin (topleft) and Delete (topright) buttons. The video on mozilla.org shows the same.

I am at China. I use Chinese local version.And the left corner is edit. Or do you have add button at last row of dials?

There is no edit button in the upper left corner, only unpin. Are you using an add-on? If yes, try in safe mode to verify. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

I have the similar issue. Firefox 17.0a2, Windows XP 1. Create a local HTML file, for example, C:\TEMP\index.htm 2. Open it in Firefox, Ctrl+O -> file:///C:/TEMP/index.htm 3. Bookmark this file, for example, to Unsorted Bookmarks. 4. Open the New Tab page and the Library, then drag the bookmarked link somewhere on the page. 5. FAIL: instead of be added to New Tab as a thumbnail, our file is opened as HTML on the current tab.

I use the safe mode.You are right,add-on make this problem. In safe mode,the default new tab page don't have edit button. Thank you very much,please close this bug. @Slavic I try your step,drag bookmark to New Tab added rightly.You can select help->Restart by safe mode to try again.

The Safe mode (without any addons) does not help in my case. Local HTML file cannot be added from Bookmarks to thumbnails on the New Tab page anyway, it opens instead. This is an internal problem of Firefox (Aurora in my test), not due to additional components. Maybe our issues have the different roots and only result looks similarly, so the title of the issue is suitable for my case too. If so, I should file a separate bugreport.

I see your issue, a local file can't be added to the New Tab Page contrary to a normal URL. Indeed, it would be better to fill a new bug, because the issue of the initial reporter is fixed. Just paste the bug link here. :) (In reply to sd6733531 from comment #9) > I use the safe mode.You are right,add-on make this problem. > In safe mode,the default new tab page don't have edit button. > Thank you very much,please close this bug. > @Slavic I try your step,drag bookmark to New Tab added rightly.You can > select help->Restart by safe mode to try again. Thanks for the feedback, I closed it as invalid because the culprit is an add-on, not FF itself.

Done: bug 787081
