Answer #3
If you need to use a browser and float about for add-ons, it may be worth asking yourself a question ;] Shall I use a desent browser apart from this. www.opera.com
And for , before I will get my post edited without this.. It’s because some add-ons only work with certain builds of FF ..
Answer #4
they were the exact same build.
i downloaded firefox to my laptop, and kept it on there.
put windows on this computer and installed the same ff.
then i just updated both laptop and desktop at the same time, from same site so im guessing they are the exact same build.

My Kaspersky blocks add-on installations on ff… Maybe your AV / Firewall does it too?
