I used Firefox up to version 3.5 and it worked well. But ever since, FF has frozen as soon as I've opened a webpage other than Google. FF even freezes when I'm in Mozilla's help pages ! I have trashed and reinstalled several times, updated constantly as suggested. I'm now using (or trying to use) version 25. No success. I have done everything that was suggested :

- trashed and reinstalled ( several times over the years, to see if new versions of FF would work) - restarted FF in safe mode - tweaked the profile as recommended - I've painstakingly checked that all my plug-ins etc were up to date. They are.


None of these solutions have worked. As I have written more than once, none of them should be necessary : Firefox should "just work". After all, other browsers do - I use Safari and Chrome, for instance, as well as SeaMonkey. Does any one know what's happening ?

I'm now running Mac OS 10.9.

This should be a simple process, as I have done it before on other computers - but the icon is only in my dock as a "?", which I click on , and then it opens up to the Fox/World icon. As soon as I shut down the computer - the Firefox icon disappears.

I am running Firefox 55.0.3 on an iMac El Capitan. I keep getting Access Denied; you don't have permission to access (URL) on this server, for a few sites only (sites I've accessed in the past). I've cleared cookies, cache, and history, I've refreshed Firefox, I've disabled all add-ons/plug-ins/extensions. I've also tried the sites with other browsers (so, yes, I know it's not just Firefox, but I was hoping maybe you could help anyway...) Thank you.

I downloaded Firefox 50 via the built in update. When I hit restart to install the update, I get a window saying that Firefox wants to install a "new helper tool" and that I need to enter an admin password to complete the update. I can't find anything about this "helper tool" in the release notes or through a google search. I was wondering just what is it? Running OSX 10.11.16. Thanks.

Hi, The subject is sort of self explanatory but for the last few months (not sure exactly when) i have had regular Firefox crashes, it seems to happen when i'm out of memory and FF has used all the available RAM. I have a MBP with i7 and 8gig of RAM using the latest OSX 10.9.1 and latest FF 26. I always keep up to date with the software. Usually i have about 20 or so tabs open and go back and forth between these. I have googled and read allot on this topic and most people recommend starting in safe mode, without add-ons , creating clean profile etc and i have done these but slowly i get back into the same issue even after a clean profile.... It seems for every FF update the memory usage increases....back in the day FF was extremely fast and efficient. Or maybe latest FF just wants to remember so much and save just to much old information which leads to these ridiculous amount of memory usage, i tend to go over 3-4gig RAM after half a day alone before it crashes and all my tabs are lost which is extremely frustrating. Is there a way to limit the memory usage? Only helpful tips i have found so far that seems to remove allot of garbage from the cache and the footprint is going to about:memory and run the "minimize memory usage", this has been working great and so far after 2-3 hours its steady on 900meg (more or less) with 16 tabs open. Isnt this something FF needs to do regularly to get rid of old stuff ? i saw youtube and many other old stuff in the cache which i was not using and caused FF to go over 2 gig or so before i run this so why isnt this automated? as a user i shouldnt need to care about such thins really. I also used Safari for a few weeks with same amount of tabs and it never goes over 800-900 meg. I really hope you guys can explain and give me some tips as to how to limit the memory usage of FF and not the regular make a clean profile and generic tips. I really think the problem is FF and nothing else. I done extensive testing here and i'm using just a few add-ons Adblock plus All in one Gestures Swedish dictioanary Downloadhelper Screengrab Download Statusbar

Sorry if i sound irritated but having to lose my tabs daily and being forced to bookmark my tabs constantly just in case FF crashes has been bugging me for a while now and i'm on the verge to switch browser but frankly there is no other browser as good as FF (offering same amount of plugins/add-ons) so i badly want to use FF if possible.

If you need any more info let me know.

Cheers

Firefox no longer seems to be syncing my bookmarks among devices. In particular, the bookmarks I add on my work iMac do not sync to my android phone or my home macbook pro. I have done the following things to attempt to get things working:

1. Turned off firefox sync on all devices and then back on. 2. Deleted my firefox sync account and recreated it. 3. Deleted and reinstalled firefox on both my android phone and my macbook pro

I have also gone to about:sync-log and see that I seem to have lots of sync errors. I've attached a screenshot of the sync-log screen. I can't seem to attach the txt file of the latest error log, so I'm attaching two screen shots of it as well.

If anyone can help me out, I'd certainly appreciate it!

Operating system: OS X 10.9

Starting about four months ago, I began to see untitled and non-selectable windows spawning after my browser had been open for a while (i.e. after I visited a few sites). The number of these invisible windows grows over time, but are removed if I close the browser and start a new session. This has persisted through many new versions of Firefox.

I tried turning off all of the add-ons. Still happened.

I tried keeping track of what sites caused the problem. No correlation.

Today I uninstalled Firefox, using AppZapper -- which should have removed everything -- then did a new install. The only thing that I imported were bookmarks from the backup directory in my old Profile folder.

...and it's happening again. Here is a screen shot: http://imgur.com/ojcODd1

Any help would be appreciated.

Hi all,

I rely heavily on FireFox (primarily for the multiple profiles and extensions it provides), so deperately trying to solve a problem I'm having. When I launch Firefox on my Mac (10.12.6 - Sierra), I immediately receive an error: "Firefox quit unexpectedly."

I've tried a number of different approaches to resolve including:

1) Starting Firefox in safe mode (by holding down the opt key on launch) - same error occurs 2) Removing Firefox from the Applications folder, and removing Firefox folder from the Application Support folder under the Library (which also removes all my profiles). Then reinstalled Firefox 57. - same error occurs 3) Tried installing older version of Firefox - version 56.0.2 (after removing previous installation as per step 2 above) - same error occurs 4) Tried a machine restart (very early on) - same error occurs.

I've run out of ideas, and hoping someone may be able to shed some light or suggest further troubleshooting options? Desperate to get it working again!

Cheers, Mark

I created a new FireFox profile. I launched FireFox using this profile, and closed the default windows. I disabled all extensions. I quit FireFox, and relaunched it. I verified that all extensions were disabled. Only extension is Troubleshooter (previously installed on a test sequence I messed up) Only Appearance is "Default 27.0.1" No Services.

I opened an about:memory window.

In a new single window, I opened the URL...

http://www.toscanamall.com/en/content/3-terms-and-conditions-of-use

I waited for it to load, and FireFox memory (according to Activity Monitor) was bobbing around 200MB. After a few minutes, the memory use was stable around 200MB. I saved my first about:memory report (#1), and then minimized the toscanamall window. I did nothing except move the mouse once in a while to keep the machine awake. During the next 5 minutes FireFox memory use went steadily upwards from the ~200MB to 575MB. I saved the next about:memory report (#2). I un-minimized the window - memory use went down to 270MB immediately, and I saved my 3rd about:memory report (#3).

There were two upgrades very close together. I upgraded and now have 29.0. No matter whether I'm going to an address, typing into a box, or waiting for a website to load, the Mac "beach ball" will spin for a few seconds before loading. I use the default theme. I have minimal - (Xmarks and Trend micro), which weren't a problem before. Is there something I can do besides disabling the add-ons?

Thanks in advance for your help.

I just got assaulted by the new Quantum 57.0.4 it is BLINDING. I am shouting sorry as I can barely see. My eyes are smarting and tearing and I can hardly read the tabs, the contrast between the dark tab and the name of the tab in a sort of muted white or grey makes the print difficult to read -- and any red fades out (as is natural in the dark, it's physics). So the screen is extremely bright, like white light, and the tabs are extremely dark, the letters obscured, any red logos tend to be muted into the dark, and I have a sudden splitting headache. I was fine with the previous Firefox. I just checked Safari -- I'm fine. I think this is a health issue.
