I have been using FF as my main browser for years. While most of the world moved to Chrome-I stuck around because Chrome's bookmark sync would rearrange every bookmark in a bookmark folder. This was years ago, but then I started getting concerned about Google's tracking and have stuck with FF since. (I gave Chrome a chance years later-same exact issue.)
During this time I kept running into reasons to keep FF besides the bookmarks:
- I have noticed Chrome isn't as speedy and responsive as it used to be.
- I found plugins that suspended unused tabs so I can have 40 open with minimum issue pre-FF Quantum and keeps memory usage down.
- There are other plugins that I couldn't find in Chrome's store, such as the SQLite browser. (Now I use DB Browser from the Arch repos.)
- Chrome's memory usage shot up over the years. It always used a lot of memory with all those processes to sandbox the tabs, but FF kept getting more features without so much bloating.
- I have seen a few sites that FF does not like, but I have also seen different sites that's didn't play well with Chrome too.
- Google's business is in ads and tracking-how long until they ban ublock origins?
However FF still has issues that were never solved or crept up:
- Website PDF printing on Linux is terrible-the websites look mangled while Chrome can take the same sites and print out a decent PDF copy.
- Chrome is usually first to have features that could be the future of the web. Subtitles for HTML5 video-webvtt. WebAssembly, I had to use Chrome to use FF's own webassembly tools because I didn't use Nightly.
- Chrome's PDF reader works better than FF's open source JS one.
- Pocket... back when it first announced I wondered why...? an organization committed to open source and open standards used a closed source service backend and if I remember at the time, a proprietary connection. It was the first time I considered going back to Chrome. I have an instapaper JS booklet that will save any page I am on to instapaper; does the same thing without an annoying little icon in my toolbar.
- Mr Robot... why......? This is the Orwellian worry I had that Google would do with Chrome. Never affected me, but did piss me off.
The Pocket and the Mr Robot were real issues to me that made me consider finding another alternative.
