There are many problems everywhere in the world. War, wherever it is occurring, is bad. You do not have to use up all your time thinking about this specific problem.

I suggest going for addons recommended by Firefox.

For blocking ads and other annoying content, I suggest uBlock Origin. It allows you to customize your experience, and can have the same or better effect than some other extensions. It is also not recommended to use multiple ad blockers, as they may conflict with each other.

For translation, Firefox Translations is fine.

Search by Image, I never used but it is recommended.
