Haha, I can't call it ton of tabs.
My usage of tabs is pretty intensive, I guess. I use them like temporary bookmarks I have to have a look at, and/or to find things very quickly (thanks to the tab search).
The week before Christmas, before I decided to nuke all my tabs for the holidays, my work computer's Firefox Nightly was handling more than 500 tabs (despite regular cleaning). Just even try to get 100 random page tabs in Chrome, if you can. If you are just able to, I'd say you have a pretty good amount of RAM.
After a few days back to work, and still careful cleaning, I currently hold 61 tabs on this browser on macos, more than 400 on my own linux laptop, more than 50 on my mobile nightly (and a dozen of addons on it at least, where do I get that on Chrome ?).
Oh and well Firefox containers are also pretty awesome, I currently use in this browser 4 browsing context together in just this serie of 30 tabs (I use a panorama-like addon to have it back to manage more tabs)
I generally avoid apps if I can (not only for some obvious reason, but moreover because my current cheap motorola android phone only allows to install new apps if I uninstall other ones, because you know I only have 200MB free, even if this is a small app...) and I stay on the web version of the mobile service, currently the "install my app" on every website (often on every page of it, despite having addons to nuke those banners) is pretty terrible, and it bothers me quite a lot, enough for me to drop visiting/using some service apps
I have a weekly hangouts for my work, and google decides it needs a dedicated plugin for FF, not for Chrome. If I go instead on talky.io for example for the same call, I actually have a better video experience than hangouts on both firefox+plugin (which can be sluggish, hello stupid plugin !) and Chrome.
When I do any search on Google ( rarely happens now, partly because of this, I'm using most of the time duckduckgo ) Google tells me to install Chrome to have a better experience...
When I open Gmail, it tells me in FF that it needs a plugin for running hangouts text discussion ( but behaves ok without it). Did google have no engineer in the last 10 years for needing a plugin for IM ? Seriously ?
When I click on the call button of Slack (the website, not the app, hello Slack, you cost me 10 time less memory for my 5 Slacks if I'm using FF tabs instead of your dedicated Chrome based app !!), it tells me "Please switch to Chrome".
Yes this 2014 post is fcking right, we're back to IE6 stage, but know your true OS (the web) is controlled (not totally, but still a lot) by Google, whereas Microsoft could never make it with MSN ( I mean before MSN was an IM service, at the start it was an alternative web owned by Microsoft), so at some point IE6 was still better than current situation
Oh, BTW, My ZTE open C using latest version of FirefoxOS was fcking awesome (despite its bad screen and its worse camera), came from ok to good to awesome when I decided to updated regularly to the latest version of FirefoxOS. Performance was so great with this bad hardware I was just baffled(even webgl games worked pretty well). Some little stalls apart, really understandable given the hardware, it was almost as good as my 10 time more expensive Samsung with 10 time more memory, lot better cpu and gpu.
This little phone became awesome only when Mozilla implemented the Webextensions standard in FFOS : you could easily write OS-wide extensions ( like ad-blocking... yes OS wide adblocking would have been really easy, but in general it was meaning total user control over the phone thanks to third party developers).
When they announced they'll stop working on FirefoxOS (for phones at the time) -- and they had reasons to do it -- I was having at least 40 tabs open to try finding a better phone I could buy with FFOS, or at least on which I could deploy FFOS on it with an actually good hardware ( notably a better camera, better screen and bigger, and some more CPU/ram to see where it could compare to my android with the same kind of hardware ). I never bought that first power user phone I dreamt of, and I really think it would have become my main phone, not a secondary one like my "toy" ZTE open C
