Support for OperaGX

Is your feature request related to a problem? Please describe.
Its the problem with browsers like opera doesn't support new tab extentions.

Describe the solution you'd like
Today a friend of me released a "extention for extentions"(let me call it that way) that resolves that problem by a simple trick.
I've suggested this "tool" already other new tab bowser extentions I tried to use before. So I now want to bring it to your extention as a potential fix.

Basicly you just add a script and adjust your manifest.json(or you can integrate it into existing scripts).
If you are interested I can also try to make a pr with the fix.

Describe alternatives you've considered
Not be able to use the extention

Additional context
Hope this doesn't count to you as an advertisement, I just wanted to bring this up to your solution as I wanted to use the extention since a year so I'm happy to now have a possible way to help making it working for others.
