A few hundred tabs? I do a lot of browsing, part of my work is to browse media, photos and tech so have a lot of tabs in groups open but I have never opened a couple of hundred tabs at once nor do I know of a single soul who has.
Unless you're on about testing for the sake of testing, in which case that's pretty meaningless!
I realise that I'm in the minority here, but there is a number of users who carries on browsing web like this. Things like tab groups don't exist in Chrome, and it's one of the most used features by me in Firefox.
I'd rather not explain my browsing patterns to you, but let's just say I have a lot of interests and read a lot when browsing web, so having an open session with up to 200 tabs open is not uncommon to me. I know you browse Reddit, so just take a look at some of the Firefox threads there, since Firefox users tend to use the Suspend feature quite a lot to help with memory management. In fact, the browser almost never uses more than 1.5 GB of RAM, whereas in Chrome, it would probably crash in the same environment (I've never tested it that extensively, since the session and bookmarks manager is so bad there).
The last part sounds like you're overly paranoid about Google and I don't think that kind of paranoia merits any solid ground without justifiable evidence to back it up. Google are an advertising company, of course they're going to monitor their services to see what's trending. How else are they going to continue to make money from ad revenue in those services.
I'm sorry, but I fail to see how acknowledging that Google collects its data through a myriad of web services is being paranoid. It doesn't stop me from testing Chrome dev from time to time, but I'd always be concerned about privacy when using it (to some extent anyway).
Are you disagreeing that they would ever use the information gathered against you? There have been a few cases of prosecutions after Google has given the data to the authorities. Whilst I'm not against, but it worries me that they might be able to manipulate that data for some future agenda, other than targeted advertising.
As an example, the open source Chromium still redirects to Google servers, even with all the extra features disabled, meaning that your web activity might well be monitored.
Kept adding new stuff, got slower and less stable.
I just can't get on with chrome, just like I don't get on with dolphin on ipad. Despite people raving about it.
Firefox has never been faster, though. In fact, it's faster than all the major browsers now.
