When accessing a select box - for example a date, from a drop-down box, it becomes impossible to select. Also the minimise button stops working. This appears to be random and will be ok for a while and then suddenly stop! Any clues why?

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, Open websites, and some Preferences.
To Reset Firefox do the following:
- Go to Firefox > Help > Troubleshooting Information.
- Click the "Reset Firefox" button.
- Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
- Firefox will open with all factory defaults applied.
Further information can be found in the Reset Firefox – easily fix most problems article.

Try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
Thanks to both - but no luck!
Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
Try to do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.
Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
- Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
Tried the safe mode and reinstal - problem persists. I'm begining to suspect some of the Acer bloatware...
