Thanks!
Not only for Firefox, for Opera too.

And… I know, "Opera is still unsupported browser", but please don't ignore this browser :)
Opera 12.10 (currently in Beta) works fully fine with MT.

I'm still having problems in 4.38 with the Accept Comments and Trackbacks checkboxes on the edit entry screen.

Thank you for this! Now I don't have to switch browsers.

Great job guys, even though i would advise FF users to consider Chrome ATM !

Good news ^^ I'm going to test this. Thank You.

Hello,
Does the 4.38 patch work for Movable Type Pro version 4.23 ?
Or am I forced to update Movable Type to 4.38 ?

Thanks for your answer.

I tested it all the way back to 4.32, 4.36 and 4.37 and it works

Hello,
For information, I installed the patch on Movable Type 4.23 et it seems to be ok.
Thanks !

I tested it.
it seem that work, i will test a little more

Hi
What patch version should I use if using MT 5.12?
Cheers
Isaac

Ditto on this--having the same problem in FF 5.12 and would like to know which patch to use. Thanks!

Ermmm... that's MT 5.12 and FF 16.0.2

Thanks for the patch. Everything is ok now.

I'm using Firefox 17.0.1. I cannot sign in in MT Native or Typepad to comment on my blog. I can comment anonymously, though. IE9 and Chrome both work fine. I can sign in to my dashboard and create entries with Firefox, though.

FWIW, I WAS able to sign in here. Is this not MT5.2.2? By the way, I didn't have to use the captcha ... because I signed in?

Copied the two files in the proper directory but nothing changed :-(

I've exactly the problem described: check the Category (or Categories), hit Publish (or Update, it's the same) and there's no Category at all.

Now I have to create new Categories, in order to have one set. But clearly it's not a solution.

MOVABLETYPE 5.2
Many thanks

Whops.

I did a complete cache refresh and restarted Firefox and all works now.

Thanks!

Hey, I'm curious what exactly is the difference between 5.14 and Movable Type 5.2? I'm getting some weird errors updating between the two, I'm thinking of reverting back to the old versions?
