When using firefox for email, I am now unable to open any attachments. It has happened during the last week, before this it was fine and I haven't changed any settings (that I am aware of).

I have tried all the usual reboot stuff and looked at as many settings as possible, but nothing jumps out.

The same email attachments open fine in outlook, from my iphone and in ie, but I prefer the firefox as I am used to using it for so long now. Also, old attachments that I have opened in the past will no longer open.

Never had any problem before with opening attachments. All programmes are affected - word, excel, pdf etc.

Thanks - Jacki

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: This will cause you to lose any Extensions and some Preferences.

  • Open websites will not be saved in Firefox versions lower than 25.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Thank you.

Thank you - actually, I was about to try this. Accidentally clicked onto the BT-mail icon at the top and it opened a copy screen of emails, from which the attachments did open. I've deleted the old bookmark and put this new one on and so far it appears to be working again - computers !

Thanks anyway - Jacki
