Firefox dev edition v84 won't start
Hi there folks :)
My ff dev edition v 84.0.0.7628 just won't start. It doesn't show up in task manager, not even briefly when I attempt to start ff. The only reference I can find to it starting is within task manager and the following are the events logged immediately after, apologies for the verboseness of the logs, but I thought they may be useful in identifying the problem.
For the record, I can find no trace of iseguard64.dll or iseguard32.dll on my system as I have read these have caused problems in the past!
Thank you for any assistance that you can provide.
There is a stack of six events in total:
