Ah, a new year, 2020, a new Firefox, and time to vent. I've always hated Safari, such a "mushy" browser, with that slick and nauseating Apple sheen. Ugh. And Chrome -- if you want to sell your soul to Google's brand of "surveillance capitalism," be my guest. So we're stuck with Firefox. Firefox was OK, functional if a bit homely, up until they began to up their version numbers every week or 10 days. Soon we'll be up to version 172. Firefox now piles features upon features and options upon options with every new release, more than anyone could use. And "Mozilla" (who ever dreamed up that dumb name?) is so proud of their megabucks "Pocket" acquisition (neither wanted nor used by rank and file users) but -- God forbid -- if you're a knuckle-dragger who still wants "tabs on bottom" they make you muck endlessly around in CSS code for a fix, and break it with every new release. No amount of begging influences the high flying execs at Mozilla, cruising comfortably at 40,000 feet. So instead of a light, tight, kickass browser we end up with a piece of overcooked corporate bloatware. Swell. Anyway, thanks for listening folks. I owe you one. -SB

Excellent browser and love all it's features; yes I have used others; Vivaldi, Safari, Chrome, Opera; all have something to offer, but Firefox hit me with a brick, after I learned how to sync my account, so I will lose nothing. The 'Generic forks; Cliqz, Waterfox, Pale Moon and others do not present the needed security updates and new versions as quick as Firefox. Firefox is at 73.01, and is rock solid. I do not have a cell phone, so my data is synced with Firefox. I read the complaints by choice, reviews; that will not stand in my way. If you are not a fan of FF, please use another browser that floats your boat; that is using a "moral compass"

Great Update. Mozilla also just updated the Firefox Multi-Account Containers add-on to version 6.2 which now supports syncing. This is incredibly useful and has been one of the most common feature requests.

Ah, another week, another FireFox version update. Last week: 72. This week: 73. I just can't wait for version 125 a year from now. Of course, 72 broke 71's "tabs on bottom" CSS code. Will some brave soul check to see if 73 breaks 72's code? I'm sure it will. And adding a simple "tabs on bottom" preference (which tens, if not hundreds, of thousands of FireFox jockeys want) is not going to happen, not while Mozilla's top executives are busy making multi-million dollar acquisitions of things like "Pocket," which nobody wants. What happened to you, FireFox?

Sorry, but I don't know anybody who cares about Tabs on bottom. I don't think giving Firefox bad ratings because the tabs are where they are supposed to be (at the top) will help.

Many words for a complain as simple as "want tabs on the bottom". Not aware of a browser that does that and for good reason. The address bar is at the top and having the tabs next to it makes obvious sense. If you can make a convincing case as to why tabs on the bottom would be a superior design choice, I am sure you can get things moving. But I doubt that's possible. There is reasons why neither Safari nor Chromium do that. I find your one star rating a bit harsh. Having exotic requests and than giving a software the worst rating feels like overreaction.

FireFox is my main Web Browser. I have used it from when it first came out and I use exclusively. 12/24/365! Nothing else compares to it. Beats the hell out of Safari. Integrates well with extensions and is trustworthy and reliable.

v. 72.0 is out. If anything, the Standard security settings are a little too aggressive on legit sites. Smooth and fast on a unsupported 2Ghz. Catalina '09 Mini. Get it now: https://ftp.mozilla.org/pub/firefox/releases/72.0/mac/ - choose your language. Happy New Year.

This sounds a lot like you have some serious malware on your mac. I would have an IT expert take a look at your computer. Highly doubt this is caused by Firefox. And believe me, if Firefox was unable to open google.com this forum would explode with rants.

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.
