Actually you said 750.
Clearly, you have mental problems - 750 tabs is hoarding behaviour. Go and see a specialist dude. The fact Safari can't do more than 100 tabs shows that *you are the problem* not Safari. It shows you *this is a bad way to work*.
Yes - close some apps. You're doing computers wrong. Perhaps you would be more comfortable with an iPad where multi-tasking is managed for you.
Forget your example. Lets focus on your 750 tabs - as that is what you do - it's a much better example. Are you seriously saying you need 750 tabs open at the same time? How do you even remember what tabs are open, why not just bookmark tab groups? If you won't be using most of them for the next 24 hours there's no point having them open.
How are you able to go back and find a tab if you need it? You can't - you are a ridiculous, lazy, disorganised person. If there were no email notifications you wouldn't be able to find this tab to reply. You have forgotten most of your open tabs even exist. If any of your tabs contain anything time critical of importance, you're screwed - it's long forgotten.
The reason you work like this is because you constantly get distracted, you stop task A in the middle and go to task B, then task C, then task D - never finishing the previous task. This is a very inefficient unproductive way to work. Causing errors, forgetting deadlines, leaving work unfinished.
You are probably amongst the 5% most lazy, inefficient, disorganised people on the planet. But - it makes you feel better about yourself to call random people "Junior" - I guess you're too busy "managing" your tabs to get good at trolling. Still nice first try, good effort - keep trying and I'll give you a nice gold star if I hear about you doing any good trolling in future!
My free advice is over - just be assured, as several people on here have told you; You're Browsing Wrong.
Take good advice when it's offered.
I'm turning off notifications - feel free to implement my life advice. If you want more you'll have to get it elsewhere.
