Many add-ons are not really helpful but the multirow bookmarks add-on and the colorful tabs addon, tab mix plus and Last Pass are the most awesome and very important add-ons that should be made compatible with any version of Firefox and this new Firefox Quantum is incredibly awesome and I know it is still beta and not fully stable but the vast majority of the addons should be made compatible before it is fully released. Firefox is obviously one of the best browsers anywhere on the planet but it is very important that the add-ons and things like Java and FLASH are made completely compatible is important. Java and Flash are not needed on every website but there are still a lot of websites that use those so it is very important that Firefox can support everything on all websites except for the very few websites that are not safe but the vast majority of websites are fine so it is very important that all of the add-ons are compatible and even though I am not able to do any program coding I am likely the best tester you can find on the planet. I have done IT issues up to Tier2 IT for decades but I am not able to actually do coding but I can test anything although it might take me a while since I have to be at my new job that starts tomorrow since I do not have a penny saved since my wife died last year so I need to make sure I get full payments from my new job which pays fairly well but will of course not make me wealthy. If I ever became super wealthy I would help people in many areas around the world. If you want me to help you offer me at least a reasonable pay and give me the ability for the company to pay for travelling and I will be able to help and train people all over the world if needed.
