Hello,

It seems that this is a known bug on some webpages. The bug report is here:

https://bugzilla.mozilla.org/show_bug.cgi?id=736048

Mozilla are working on getting this fixed.

In the mean time there is a support question here where people have discussed various work arounds and add-ons that may help with this issue. See here: https://support.mozilla.org/en-US/questions/947337

Also have you considered trying the Firefox's 'Metro' version which is designed for touch? It is not fully released yet but you may find that it is more stable than using standard desktop Firefox with a touch screen. See here for more information:

How do I launch Firefox for Windows 8 Touch?

I hope that helps.

Thanks, EddyC — I use several extensions and plugins in normal Firefox - will they all work in the Metro version? If not, there's little sense in trying it now.

I'm afraid I'm not sure whether they will work. They will at least need to have been updated by the add-on developer to work with v26.

There may be other limitations. I know that in early builds only add-ons which use the Addons SDK would work. This is still a development pre-alpha build so you should expect some issues / limitations until it reaches full release. I believe that is expected in December this year.

If you are willing to give it a go I recommend installing it and testing out what is possible. Installing Nightly will not affect your current stable channel install so if you don't like Nightly you can just uninstall it and go back to using Firefox 23.

I hope that helps.

Thanks — I'll give it a try. In the meantime, the plugin GrabAndDrag seems to be working just fine. :-)

Great! Glad to hear it.

Thanks for the feedback and thanks for using Firefox. :-)
