To display web pages, Firefox uses the Gecko layout engine, which implements most current web standards in addition to several features that are intended to anticipate likely additions to the standards.
Fast AF now under LLVM 12 and latest Rust. Plus, they finally figured out a good way to get proper crash reporting info out of Linux. With 91 being the next new ESR release, we'll see a bump to a stable LLVM 12.0.1 / Rust 1.53 combo so that should bring even better perf on Desktop, Android and M1. Took a while for Mozilla folks to get to this point after the massive layoffs but glad to see focus back on where it matters most: performance, not gimmicky features no one will use.
A huge improvement in rendering performance over 85 and earlier versions, especially on my crappy Nexus 5X and old Latitude E6510. When they moved to LLVM 11.0.1, the overall performance boost was tangible. I had my doubts before but it looks like Mozilla is getting back to making FF better and, finally, faster. I don't know how much Rust 1.49 contributed to 86's performance improvements though. Maybe it helped the Android and Apple M1 crowd?
Yay, they finally killed Flash support. At least doing that reduiced the installer size. Yes, the browser feels snappier than 84 and 83. I can feel they've made strides in improving performance. Very snappy on my crappy old E6510. 86 is going to get an even better performance boost. Things are looking up for Mozilla. Glad the layoffs didn't kill progress.
Can still customize and hack the crap out of it. JavaScript performance on some artificial benchmarks is still down since switching to WARP. Mem use is still lower as well which is great for lower power machines / 32-bit crowd. Let's hope FF85 is all they promised and more with further WARP improvements and better Webrender support for the Linux folks. Mozilla is on a roll so let's hope they don't screw the pooch and do something dumb.
I can customize and hack the crap out of FF to this day and can't say the same for other mainstream browsers. Can't say I notice much speed improvement on the front end but my machines are Ivy Bridge so maybe a bit long in the tooth to realize the new improvements. Mem use does seem to be lower on my machine so that's always a plus. Still, we have to wait until FF 84 before we can realize Rust 1.47's improvements and FF85 before the rest of what they intended to improve in FF83 (WARP). By then the MASSIVE Rust 1.48 release should be helping improve FF perf. At least I hope.
Feels more responsive on my old machines but a lot of code in FF seems to have prevented LLVM 11's performance boost for being actualized. In fact, perf went down a bit on some artificial benchmarks. It looks like *only* by FF84 will we see Rust 1.47 be pulled in. This will hurt FF numbers, perf and user experience for another 2 months.
With Mozilla having suffered a huge employee base culling due to Covid sapping the global economy and workforce, it's forced them to really put a finer point on what matter most: a solid, fast browser experience. 80 was a look at things to come. 81 seems to have polished the improvements. 82, I see, has finally switched over to using LLVM 11-rc2....but not Rust 1.46? Come on Mozilla. That would make the Linux folks SUPER happy and help with Android a lot. I guess we'll have to wait until v83.
Bottom Line: Fast AF now under LLVM 12 and latest Rust. Plus, they finally figured out a good way to get proper crash reporting info out of Linux.

Took a while for Mozilla folks to get to this point after the massive layoffs but glad to see focus back on where it matters most: performance, not gimmicky features no one will use.
Cons: By now FF should be leveraging more of the GPU when and where possible to offload rendering. The new Warp Javascript engine still needs some fixing up to bring back performance in a few non-mainstream areas.

Bottom Line: Still the most customizable browser, period. Although some customization has been lost with the the XUL extensions now not allowed, It is still my favorite browser.
Everyone seems to be using Google Chrome these days, but I refuse to install Google spyware on my system and use a browser that will not allow a REAL Bookmarks Sidebar
Bottom Line: Allot of the minor browsers I have use in the last few years either aren't updated or not compatible with some websites. I've tried all the big boys. Chrome, Edge, Opera, whatever version of IE still exits. I still come back to the mozilla browsers as my main choice. Still have Pale Moon as a backup browser but Firefox is my main browser again.
Bottom Line: It's not perfect and has gone in some questionable directions but it's return to form is welcome. Mozilla sticking to waht works and not trying to reinvent the wheel is a good idea going forward. It's been held back by the fact that LLVM 10 hates it but looks like the prospect of moving to LLVM 11 for v82 is going to be a huge performance win across all platforms. All the work that Martin Stransky did for Linux folks is very welcome. Should only get better from here!
Bottom Line: Still my go to browsers, especially on my Android. Yes, it is battery hungry on Android but hoping when 78 ESR is released it'll be better and faster! Snappier than 77 was on my old work PC. 80 is going to be a HUGE boon for Linux folks. Good job Mozilla.
Pros: Getting faster with every iteration and still runs well on my old clunky E6510 @ Win 10 X64. Although FF70 only got a minor perf bump from Rust 1.37 and LLVM 8.0.1, FF71 is moving to LLVM 9.0.0 and, if we're lucky, Rust 1.38 so it should see a good perf improvement as well. Still needs to work on the JavaScript speed to match Chrome but who gives a fornicate about JavaScript anyway.
Bottom Line: Maybe not as fast as Chrome in a few benchmarks but certainly runs circles around Chrome on my Android in terms of *NOT* suffering browser hijacks and other issues. Works well for what I need and still gettign faster with every version.
Cons: Not enough info for going into Firefox's guts from About:Config to be able to turn off things like the new Recommended Addons (which you can).
This info should be out so people do not need to go to the Support Forum to find the answer.
Using other browsers that are built using Firefox code can be less secure and are not released at the same time nor are security updates/fixes.
Bottom Line: Not sure why this is up as 68.0.1 was released July 18.
Am thinking since the beta version of 69 is in the last faze of testing it will be released shortly.
For Extensions there are more than enough alternative ones to be found built by other Developers that are more secure and does not crash Firefox with their buggy old code as it used to.
Most older Extensions/addons were abandoned by their Developers and were not getting fixed or updated as Firefox progressed with forward thinking code and fresh ideas.
For XP users sorry but you should not be out on the net as you are a hazard to other users with a non-supported OS.
Should be kept for playing older games or running older programs.
Linux is a Viable alternative to XP.
Please install it and consider other net users.
The cloud backup is a Option only. You do not have to use Sync at all as it is not a backup. Sync is for transferring data from 1 device to another so that they are the same. Thus is named Sync.
If wanting backup use proper backup software to do so.
