p.s. I've just discovered that I also now can't open the file that Firefox is downloading because when the notification pops up to tell me that the file has downloaded and I tap 'Open', a list of the apps that are installed on my 'phone pops up but when I tap on Acrobat Reader and then tap 'Just Once' as I always (errr.....usually) do, my instruction seems to be completely ignored and Firefox tries to open the pdf file but is apparently unable because all it displays is a blank page.

Oh and when I try and open it from my file manager, the downloaded file isn't downloading as a .pdf, rather it's being named '*-pdf', so in order to get Acrobat Reader to even open the file, I'm then having to Rename the file to '*.pdf', at which point when I tap on it, it opens perfectly well in Acrobat Reader......finally!

You can see why I want the option to simply view the file without having to download it, just like I was able to this morning

Hi Dan

As a first step, I recomend that you update your copy of Firefox for Android at the Google Play store. The information that you have provided with your question indicates that you are using an older version of Firefox for Android and may be missing important security and ability updates.

Hi Seburo,

Thanks for your reply.

I've updated Firefox as you suggested (I thought it would be auto-updating like my desktop version does) and was hoping that there would be some new setting in the updated version that was going to solve the problem that I reported for me but it seems that this is not the case.

Now that I've got the latest update, do you know how I can solve my original problem?

Many thanks.

Hi Dan

I have found this article that should help:

Hi Seburo,

Thanks for your message.

Unfortunately, as I mentioned in my original post, I'd already tried changing the default apps settings, save for resetting everything, which I've now done to no avail, so the article didn't solve the problem.

I'm confident that it's not a default app setting that is causing the issue because the problem isn't that one app is opening where I'd prefer another to open, the problem is that when I click on a pdf link (or link to any file), where I used to be offered the option of either downloading the file or simply viewing it, following my errant button tap, I am no longer given the option, so every pdf link I tap now results in the document being downloaded, which is littering my download folder with loads of documents that I don't want.

This means that I'm now having to go to my download folder via my file explorer app every time I tap on a pdf link to firstly view the pdf, where I was previously able to simply tap 'View', and then to delete it. In addition, again, as I mentioned previously, I'm also having to rename the pdf file before I can even view it because, for who knows what reason, they're downloading and being saved as 'Document-pdf', instead of 'Document.pdf', so, until I've made the filename change, they're not even recognisable files, so won't open with anything.

All-in-all, this single errant button tap has caused a phenomenal number of issues, which is wasting a significant amount of my time and is simply frustrating!

Yay! I've fixed it!!!!
