The FTP method is the best method - https://ftp.mozilla.org/pub/firefox/releases/58.0.2/win64-EME-free/en-US/

You can browse through the folders and download any version you want, no BS hand holding stubs, I linked you the one I think you need. TBH I don't like Stub Installers and as a PC tech I need the full installer right in my hands, can't waste time waiting for it to download or worse, get stuck without internet.

Everything considered, Firefox is still pretty good. Version 57+ is fast and I like the interface better, the addons were a blow to me however, I had to search for some alternatives but I've managed and will hang to it for now.

I ditched firefox the moment google chrome was released , now stuck with chrome , the yahoo deal back in the day kept me off for good and now this.

Firefox was the anti ie browser back in the day now it seems to be a crazy bus with no proper path.

netscape navigator -> firefox -> chrome

I'm more annoyed that I can't upgrade due to various unsupported useful addons.
And about FF dumbing down and slowly losing useful options to appeal to the crowd that uses 1 tab, default settings and 0 extensions.

I read this as RIP Fairfox.

I think that the idea is that most users shouldn't mess about in about:config or chrome:flags at all.

Personally, I use regexps all the time. 15 different search-and-replace actions, or a single one using regexp? Yeah, I'll take the latter.

For personal use, I've been using Vivaldi, which replaced my Opera 12 (newer versions of Opera were shite, so I stuck with the old one until Vivaldi became stable). I also have Firefox 22 at home, heavily modded for the look and feel of Opera/Vivaldi (mouse gestures, page tabs on the bottom, etc). I just never got used to the "minimalist" Chrome UI.

Unfortunately, at work I need to keep my Firefox up to date and use it almost daily, as I manage the QA team for our Web applications. I've seen a massive decline in the usability of Firefox over the past few months. With the introduction of Quantum, most of my extensions stopped working (I know that the extension developers have had enough lead time to rework their extensions, but from a user perspective Firefox is the front-end and will get most of the blame). In addition, just launching vanilla Firefox on my Win10 computer immediately spikes CPU usage to 100%, and this stays until I shut it down. For me, Firefox has died with Quantum. It has simply become unusable for the regular user, especially with so many other, better options.

(That said, I still prefer Mozilla Thunderbird as my e-mail client. Here's hoping they won't screw that up.)

If users aren't supposed to be in Chrome://flags, then why is it presented in a friendly and descriptive way? And why are there useful tweaks like tab muting in there?

What is regexps?

Because someone thought that just because it's an advanced feature, it doesn't have to look like a spreadsheet, maybe?

Reg(ular )?Exp(ression)?s?
Sorry about that :-P

EDIT:
For the record, that matches:
RegExp
RegExps
Regular Expression
Regular Expressions
RegExpression
RegExpressions
Regular Exp
Regular Exps

Of course, (RegExp|Regular Expression)s? makes sure the latter four are not matched, but that looked too boring.

I have also recently switched to Vivaldi, and thus far I am happy with it.

That doesn't sound very nice. Almost too bad to believe. Can't check out for my self because I would need to uninstall Firefox first which I do not want to.

I'd consider making a full move, but it needs a little je ne sais quoi for me to be fully satisfied with a move.

Either an extra feature, or a degree of separation from Chrome, I suppose.

Have you tried the portable version? I use Pale Moon, Opera, Firefox ESR as portable versions and Firefox Quantum installed the normal way.

RAM usage is insane too, 5-8 tabs need more than the entire OS.

I forget which function it was (It's been years) but I relied on an accessibility tool that was removed but replaced with a plugin that relied on an about:config line. A few versions later that line was also removed since developers didn't want to have to keep making sure that function still worked.

It's in my notes somewhere at the office so I;d have to go did it up. Downloading rings a bell but I doubt that was what it was.
