Recently I wrote that Firefox is slow .... and now there is a new version: 70 :) It's better, much better. Firefox now has a new faster Javascript Baseline Interpreter and compositor improvements that... (I quote from mozilla) "reduce power consumption, speed up page load by as much as 22 percent, and reduce resource use for video by up to 37 percent". Apart from Mozilla marketing: Firefox now works quickly and efficiently. I recommend, check it out for yourself.

When you have 100+ tabs open FF is uses the least memory and runs faster than any other browser I have used (Chrome, Vivaldi, Brave, Opera, never really got into Safari because of the lack of customisation, extensions and integration into other platforms). My problem is that there are some essential extensions I want to use but they are not available on FF (e.g. Gmelius, Hubspot etc.).

Have you talked/complained to the authors of those 'essential extensions' about what security/processes are lacking to allow them to run on the current Firefox versions?

I have not. HubSpot is not even planning to build an extension for FF. I know, it's just a small issue over all, but it affects the workflow of my business. Although, I still believe that FF is the best browser at the moment.

ps - I don't understand why a review from 2009 should get the top spot. It is hardly relevant 10 years later, except for the link to acid3. The "most helpful" algorithm needs to have a time decay built into it.

It's the best browser and moved out from Chrome for security reasons. Chrome is having lot of Adware and collecting too much of data leaving behind without any option to disable.

I am still using 61.0 because that is when the comments section in the bookmarks was removed. Does anybody know if it has been added back in yet? As much as I would love to upgrade, I find myself using Chrome a lot more, so I can keep my comments section in Firefox.

Some nice additions/improvements for FF 69: For our users on macOS, battery life and download UI are both improved: macOS users on dual-graphics-card machines (like MacBook Pro) will switch back to the low-power GPU more aggressively, saving battery life. Finder on macOS now displays download progress for files being downloaded. Enhanced Tracking Protection (ETP) rolls out stronger privacy protections: The default standard setting for this feature now blocks third-party tracking cookies and cryptominers. The optional strict setting blocks fingerprinters as well as the items blocked in the standard setting. The Block Autoplay feature is enhanced to give users the option to block any video that automatically starts playing, not just those that automatically play with sound. For our users in the US or using the en-US browser, we are shipping a new “New Tab” page experience that connects you to the best of Pocket’s content. Support for receiving multiple video codecs with this release makes it easier for WebRTC conferencing services to mix video from different clients.

It is still a good browser, trying to adapt to new times. I don't know about the Windows version, but the Mac version is still slow. Consumes a lot of resources (especially when playing video). Rather, it is no longer an interesting alternative to Chrome or Safari, even though Firefox is still trying to modernize. The only plus may be that it does not belong to Apple or Google - for many people it matters.

Utter rubbish, badbadger. If FF is not running faster than Safari or Chrome on your Mac, you have something wrong on your machine. FF is customizable with many, many more extensions than Chrome, let alone Safari.

@badbadger is actually right, @Scion777. Safari uses less resources to play back HTML5 video, in my tests about half. However, this seems to come at a price. This Linus tech Tips video: https://www.youtube.com/watch?v=Po5iEqDDv3U will only show in 1080p in Safari 12.1.2 while Firefox 69.0.1 allows up to 2160p resolution.

FF is as slow as molasses for me; almost unusable. While I've followed all of Mozilla's instructions to clean it up, refresh it, etc, it's still a no go. I was forced to switch browsers and am now using the Chrome-based Vivaldi. The difference in speed is astounding – night and day. I've been with FF since the beginning, but the sloth-like performance is now a deal-breaker.
