Firefox - though I tick the always open with button still prompts me

Even though I tick the box "always open with" Firebox still prompts me to select the application. See example below.

It happens for ALL file types, and in Thunderbirds too. I have tried reinstalling, deleting profiles etc with no success.

Try reinstalling the application you use to open this kind of documents.
If you open firefox and go to Edit -> Preferences -> Applications

Find the PDF and select your default action.

Go til File -> Exit

Start firefox again and see if it happens again.

If it works I'm afraid you might have to repeat for every file action that does not get saved.

What OS are you running?

There is an explanation for this phenomenon: Firefox uses MIME types, not file extensions to classify files. In order to get the correct MIME type, it depends on the definition given in a web page. If that definition is incorrect or non-existing, Firefox has to make an educated guess as to the filetype, but since this leaves a chance of guessing wrongly, it still asks you what to do.

Here's more explanation about FF's filetype handling, and some tips and work-arounds that may be of help:
