Hi after updating Mozilla Fire Fox from a pop-up saying that i could now update to 4.0. After updating I found I couldn't get into my email with Tiscali or book a a delivery slot with Asda and check-out.
using Opera I found no problem getting into my mail box or selecting a delivery slot.
Reverting back Fire Fox 4 I still could not access my mail or Asda for a delivery.
After reverting back to Fire Fox 3.6.16 all went smoothly with my email and at Asda.
I sent a report to Firefox just in case there was a glitch.
Having encountered a few niggling glitches in FF4(I installed it into a separate folder alongside FF3 but it still accessed the same profile and was obviously not happy with some of the non compatible items in that profile) I started all over again.
This time I installed FF 4 into a separate folder but also created a new profile and started to build on that afresh.
FF 3 remains fully functional in its current state.
So i now have both FF 3 and 4 each working off their own profile. As more of my essential add-ons become available for FF 4 it will eventually completely replace FF 3 which can then be deleted.
