Have been a die hard Firefox user since before switching to mac from Windblows.
But am concerned with mozilla's terrible customer support and releasing faulty versions lately that crash and hang. I pray this gets fixed as I don't want to use safari or opera substandard browsers.

Just want to thank the kind person who emailed me the Firefox downgrade software access link earlier this week. I wanted to thank yo sooner but was unable to reach MacUpdate due to ongoing 27.0.1 constantly crashing but just now I've seemed to have discovered a temporary solution. I used the free program iBoostup which scanned my Internet setting and suggested I make some subtle changes to my Macs Intranet DNS settings. I just did as suggested and walla Firefox just stopped crashing! I'm so grateful right now.

Reverted back to 27 with time machine...seems to be back to normal; not sure why there is a problem. Advise people hold off until the next update.

I've been using Firefox for well over a decade but version 27.0.1 hangs and crashes constantly on my mac and is now completely useless! 27 worked fine for me but I don't have time machine hooked up. If anyone can direct me to an older version download of 27 I'd be grateful.
Right now I'm going to have to use Safari which I hate but have no choice. Why do the folks at Mozilla act like nothings going on?

BEWARE of version 28. It cannot quit (force quit is necessary), and it often hangs the system (imposing to restart the Mac).
The FF developers who implemented this version as the default update in the about menu are irresponsible.

Actually the impossibility to quit FF was caused by an add-on : Privacy choice trackerblog (versions 2 and 2.2)

Excellent browser! Not the fastest (Opera 19.x is), but it is stable & better than Safari

For those who have CPU usage issues, you can use XSlimmer to remove unnecessary code from the browser and it will eliminate the CPU usage problem. It's not the only app. to have this issue.

Oh PLEASE be better than v26, which has crashed more times in the past month than any single piece of software I've used since OS9 days.

I've loved Firefox for years now since v5, but the last couple of updates have just killed it with stability (I hear the PC version hasn't been any more stable from my PC pals). I'm such a fan of Firefox, all my years of Bookmarks are in Firefox (wish they'd introduce a proper export function instead of the half-tailed version they have now), and it's my go-to.

But v26 has completely sullied the experience for me on multiple Macs, and I've even launched Chrome for the first time last month.

Am so hoping that v27 is back to stability again. Fingers crossed in a few days of usage. Downloading now...

I COULD use Firefox as my default browser, but still with version 27 its CPU usage is just too high for more intensive use. When using it I have to keep eye on CPU just to see when it bounces again. And so I have to restart the application. Not good. I have always had these issues with Firefox.

At the moment there is no single browser on Mac that beats all, now that FreeSMUG's Chromium is on hold / dead.

Still my favorite browser. But since 26 I cannot quit FF anymore. The CPU usage rushes up to 99% but nothing happens. No sinning wheel, no closing windows… it stays at it is. Strange. Has anyone an idea?

@foolishservant. Yes you are right. Google money has (probably) nothing to do with the quality of the software. I go back to 4 Stars :o) Fair enough?

FF 24 has issues. Many downloads end up in 0 byte files. Also happening with FF25b7. This is a huge problem. Found a ticket about this on their bugzilla. Let's see, where this goes.

Strych9 had trouble on 07 Apr 2013
Version 20 seems to have a problem with absence of character sets in header of a page.

Based on google recommendations, you should remove both character set in doctype and meta-content-type.
https://developers.google.com/speed/pagespeed/insights






It is valid on w3.org without the 2 sets.

But there is a bug in FireFox 20, not on Safari, Chrome, Opera...

The (p)nbsp;(/) are not correctly displayed in UTF-8 or on automatic recognition.
It is displayed as 2 characters "Â ".
Switching to iso-8859-1 solves the problem, which is not a good solution.
The good solution for the moment is to keep the set in meta-content-type.

Same for you guys?

Firefox 15.0.1 clearly has a problem with following Antivirus software:

- SOPHOS
- Comodo
- Webroot

Others not tested.

Specifically, if real-time scanning is on, Firefox stalls and even stops responding.

This does not happen with Safari.

Love my Firefox but recently the drop-down menus don't work. For example can't log into Twitter or if I go to dpreview nothing happens when I hover over the links. Can't explain why, deleted cookies and cache and addons disabled but no go.

Is high real memory usage (150 MB) expected with FF13 on SL 10.6.8?

FF13 refuses to quit from the Dock icon menu, although the window closes, the process remains in Activity Monitor until the icon is clicked.

Is the following message in Console->Console Messages normal on Firefox(13) quit?

6/10/12 10:51:37 PM [0x0-0x68068].org.mozilla.firefox[728] NOTE: child process received `Goodbye', closing down

"FF13 refuses to quit from the Dock icon menu, although the window closes, the process remains in Activity Monitor until the icon is clicked."

I appear to have resolved this one using some plist tinkering.

RAM on start is relatively normal (75-80 MB) but quickly goes to 180 MB with only 3-4 tabs open. Seems insane!

I have spoken too soon. This issue remains, although apparently not consistently.

For years I've used Firefox in parallel with Safari. However, since v9 it has obstinately refused to import bookmarks on its first startup after installing, even though it tells me it has done so successfully, and the menu item for importing has vanished. I've switched to Chromium as my second browser.

Hey penurie33, that was from a recent server migration we did. Empty your cache, and then you should see the proper homepage.

alas! had trouble on 16 Jan 2012
FF is my default browser; I've been on the v9.0.1 release channel for some time.
I've generally been very pleased with FF9.01, however, one fairly serious issue that I've been experiencing is the matter of ad-ons.
I've got 8 add-ons installed as well as several personas. They've all been working well, for the most part, but every so often a few will become automatically disabled as being incompatible.
Currently, all of them are disabled as incompatible. This glitch apparently happens when Mozilla issues minor updates for 9.0.1.
I've notified Mozilla about this but so far no joy.
I'd like to stick with a stable v9.0.1 instead of going w/the release channel.
Does anyone have a link to a stable v9.0.1 download?
