Today i had the weirdest thing happening with my Firefox.
I was basically unable to maximize or close it, while it was stuck as minimized, unless i did it through the task manager.
Firefox was running but it was invisible.

After backing up, deleting, installing fresh, loading up from backup, deleting localstore.rdf, backing up again and clicking on the bar like never before, i decided to trace back to the last thing i did.
I installed FF in another two folders so i can test any changes i was about to make, and load up for both the same user profile as on the original one.

Tracing back….I installed some new addons and a theme.
But how could i get in there and disable them if i couldn’t maximize the window?

Without any access to it, it appeared to be a bit impossible to get all my stuff back.

Here’s what did it:

I highlighted the stuck firefox, then hit ALT+Space+S.
That gave me a very strange view to the Firefox toolbar, which by the way was enough to get me to the tools and then addons.

Once in there, i disabled the last used theme and activated the default one.
As silly as it sounds, on restart i had no problem whatsoever.
To make sure that the fault was in that theme, i fixed the same way the two other FF’s.
The theme? Aero Silver Fox Basic.

And this was the only thing that could restore my Firefox without losing anything.

If you happen to encounter something like this, just do what i did and it will work.
