Tweetdeck update error #16824

Tip for anyone trying to update Tweetdeck automatically, and getting the above error: I went direct to the website and downloaded from there (listed as version 0.26, but after the install it says v0.26.1) The install stops if Tweetdeck is open, but you can just close Tweetdeck and continue.

It asks you to log in, and I forgot my Tweetdeck password, but the "Forgot your password?" link worked peachy. Then the install didn't claim to detect any of my groups, but it restarted Tweetdeck with all the groups I had previously.

The update solves the annoying problem of 0.25 re-showing tweets you've marked as read and cleared.

Summary: update direct from the Tweetdeck website, and the error message doesn't come up.

Weird Firefox problem and solution

The problem: Firefox was ignoring my location bar (the text area at the top that you can type a URL in, and when you hit enter, it'll load up.) I could type in it, but pressing enter didn't do anything, and changing tabs didn't change it to the new location.

The solution: (from helpful advice here): I uninstalled two add-ons: BlogRovr and Web Developer, and after the restart, it worked fine. I don't know which of those was at fault, but I don't care now. :)
[Side note: for diagnostic purposes, I did like the advice at the link said and made a clean profile, and found the location bar worked fine there, which pointed the finger at the add-ons.]
