gnome-shell extenstion page doesnt work with opera browser

hi, tried to upload LightOverview extenstion over the weekend from 
within opera browser and:
1. i could add zip file but
2. couldnt upload picture and
3. couldnt press submit button

Wonder if there is a chance to support opera in a future? That will be 
much appriciated.

Also since i tried to upload from opera about 2 times without success i 
switched to firefox - so i was in process of uploading extension and 
framework discovered that i already have out of date extension installed 
(i belive it was due to opera's two incomple uploads) - so out of 
curiosity i clicked link to upgrade extension but operation errored and 
left my hard drive wipped out of extension folder - not a good 
experience really especially when i had no backup since didnt expect 
anything like it - not sure if stopping version updates/increases for 
pending approval extensions and disabling upgrade link for such would be 
doable?

I am willing to help testing or providing more information in oder to 
address above.

Thanks for your help,
Greg
