What is Speed Dial? Does it use the Components object in content? If so, that probably needs to change. :-)

Maybe that's referring to this addon? https://addons.mozilla.org/en-US/firefox/addon/speed-dial/

Hm, I installed the addon, but didn't detect any lookups for the Components object in a debugger. Can you give more precise steps to reproduce?

STR 1. Install Speed Dial & restart browser 2. Choose "Load in blank new tabs" in the first time configuration window 3. Close browser and start again 4. Open a new tab, the speed dial is broken 5. Open one more new tab, the speed dial recovers

I guess the problem comes from http://hg.mozilla.org/mozilla-central/rev/a835569488a8

Hm, I can't reproduce this on a macosx nightly debug build. Can you andrew?

I can reproduce on both Windows 7 64-bit & Debian 7.0 32-bit.

Creating a blank profile on a fresh build, following the STR, and adding a couple of sites to my history, I get the behavior in the attached screenshot, which at first glance doesn't appear to be broken.

I poked around in the addon code a bit, and there are various things referring to Components in the code for the cache, though at first glance it looks like an XPCOM component, so it should be okay there...

Yeah, me too. Can you reproduce?

Works fine for me on OSX. What do you mean by "the speed dial is broken"? Does the page not load at all, or does it not show what you expect in the speed dial entries?

The "unavailable" for the weather report button thing appears really zoomed in briefly the first time I open the tab.

Any progress on this one?

(In reply to Markus Popp from comment #14) > Any progress on this one? As mentioned in comment 8, I'm unable to reproduce any abnormal behavior myself. Regardless though, if bug 790732 really is to blame, then it's probably going to be Speed Dial that needs to change. Can we get the developer involved here?

Fixed in Speed Dial 0.9.6.15 http://speeddial.uworks.net/CHANGELOG.html
