Are there any nice Chrome extensions to expand on Google that anyone can recommend? Would be nice to have a default Reddit setting, or a 'search reddit' button on Google. There's a couple other ones as well besides Reddit, particularly around key forums. Shouldn't be too hard to allow custom-buttons. In general now that people are here, I'd be pretty interested to know what people's top 5 extensions are outside of the regular (uBlock, Pocket etc). They're quite powerful but I don't use that many actually. In the EU I use a no-cookies extension, though imperfect. I also use 'video speed controller' religiously to easily watch/listen to content faster. But overal I find few extensions very useful and the ones I use cause issues on a small fraction of sites. Happy to hear from computer super-users what they use.
