Updating Firefox messed up my Mac

When I updated Firefox, my Mac started acting weird. First Mail started rrunning very slowly and then Safari. After I rebooted, all of my cons in the Dock went back to the original Default setting. I do not know how to get my old Mac back!

WZZZ - Sorry I took so long to reply. Safari kept crashing. I finally got it running after 2 re-boots. The problem may be coincidental, but all I know is that only change I made to my system lately was to update Firefox. I opened Firefox and was advised on the web page that there was a new version to download. I don't know what number I had but presume that the download was for the newest version. Within an hour of updating, my Mail started running really slowly (lots of spinning icon) and it would not let me open some of the older e-mails. And it wouldn't let me delete them either. Safari started running slowly and today it would not open without crashing "stopped unexpectedly".

It looks like updating Firefox causes problems with Macs. Should I update from 4.0.1 if it works? I have a Macbook Pro and have upgraded to Lion.

I've tried to update FF since I had Snow Leopard and it just kept spinning and couldn't connect. Now I see that maybe there was a good reason.

Although I am logged in as an admin, I can't check for updates or update Firefox. I'm on a Mac and would rather not delete this version and just reinstall the new version bc I don't want to lose my bookmarks. Please help - thanks.

I need to update Firefox to the latest version, but check for updates is grayed out. I am already logged in as an admin for my computer (it's a Mac), but my computer is telling me that I don't have permission to update Firefox. How can I update Firefox? I don't want to delete and reinstall because then I will lose my bookmarks.
Thanks!

'''I have also been having a problem I thought it was me or my computer'''as I am not really that good with my computer ,Also there are pages that I try to go to hat says pages busy or moved can not connect,but I can from explorer.

Since updating Firefox to 6.0, my Quicktime Pro on Mac OSX 10.6.8 won't allow me to save MP3s, although I can listen to them on the page.

I recently updated Firefox to 6.0 and it quit allowing me to save any mp3s downloaded to the page, although I can still play them in Firefox.
For a very brief time, I was able to save them after the update, and I believe it has something to do with bit rate, as I was asked whether I wanted to increase the bit rate. I clicked yes, but didn't take note of whether it was 32, 64 or something else.
Next time I restarted Firefox, it went back to the original setting and I don't know how to change it. I even purchased another copy of Quicktime to see if that would help, but it didn't.
I'm also having this problem in Safari, so it's probably a Quicktime fix, rather than Firefox, but if there's anything you can tell me, I'd really appreciate it.
Apparently, there are third-party Quicktime softwares that will help, but I don't know what they are or what they do. Can you help, please?

If you upgrade to Lion it comes bundeled with it!
To get it on your Mac Pro just copy the aplication from the aplication folder on your MacBook. You can do this via a thumb drive or over a local network connection.

I have a mac os 10.6 when I try to update firefox from 3.6 it says its still being used and won"t close it so I can install the upgrade..What can I do?

Did you do a font check in Font Book?
Be aware that a default encoding of UTF-16 as shows in your screenshot may lead to problems. 
The default is Western (ISO-8859-1) and you should change the default encoding to that setting unless you have changed that deliberately to UTF-16 for specific web pages, but even in that case it is better to make the change via View > Character Encoding or set Auto-Detect to Universal or UTF-16.

I've just updated Firefox on my mac 10.4.11 and now have to use this crummy old Safari. I want my fox back, what do I need to do?

I'm still on 10.4.11 on my mac (because I want to) Firefox will not open sense the last update. I want my fox back, what do I need to do. and don't tell me to update the mac, Grrrr!

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
* http://www.mozilla.com/en-US/firefox/all-older.html
You are unfortunately out of luck with an Intel Mac and OS X 10.4.11 
Best would be to update to OS X 10.5 or later if you want to use Firefox 4 and later versions (current is 8.0). 
There is a Firefox 8 compatible third-party version TenFourFox from www.floodgap.com for a PowerPC Mac, but no alternative for an Intel Mac with Mac OS X 10.4.

Even after update and several boots, my icon on desktop still leads to old version on Firefox. I use Mac OS 10.6.8.

I have updated Firefox in Mac os 10.6.8. severa times now. But in desktop and dock the icon still leads to old version, 3.6.24. Only if I select Firefox from programs-folder, the newest version appears. How can make the shortcuts use the updated version?

After updating to Firefox 8 Beta for Mac, no window opens on startup.

After updating to Firefox 8 beta on Mac, I tried to open a new session. Upon starting, a pop-up appeared in the upper left corner of the screen. ([[As seen here.|http://i51.tinypic.com/2z9i99s.png]])
I tried to close it by clicking Cancel or OK, neither of which was successful. Is there any way to fix this problem?

Firefox 16 versions still work with your OS X 10.5 operating system, but that is the last version that will work. 
Firefox 17 will require OS X 10.6 and later.

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Hello from Norway with a bad Englisch.

about:crashes only lists crashes that you have reported using the [[Mozilla Crash Reporter]] which comes up after a crash. Because there are so many possible reasons for a crash, getting the crash ID really helps volunteers find the cause quicker.
That doesn't mean we can't help without a crash id. :-) No crashes here, but I'm also on Snow Leopard and using Firefox 3.6.6.
Are you using Firefox 3.6.6? The most common cause of crashes on Mac is the Flash plugin. Are you using the latest version of Flash? You can check at http://www.mozilla.com/en-US/plugincheck/
Do you remember any specific circumstances about when the crash occurred? What sites you were on?

Since the later updates of in the 3.x series, I've had increasing losses of functioning of bookmarks & history, with 4.x it's gone, with latest update, Firefox slowed to non-funcitoning on my Mac Mini under OS X - What can I do to make it work again?

'''bold text'''I am not computer savvy. That may be understated.
I've enjoyed Firefox til the later updates to the 3.x version. First lost ability to update my bookmarks and history, but the old remained. With the 4.x updates, I lost all bookmarks and history and could not page back -- big problem. I have not addressed these problems because I have bigger life problems, and had hoped my husband would take care of it all. Not hoping any more. With the latest 5 version update, Firefox is not functioning, too slow to be workable, and getting hung. When it hung, it hung with a troubleshooting message, but I didn't save it. Will try to reproduce that and put it into the next section in this communication form. (I got the uselessly slow, but not the hang up message. Sorry.) It also slightly scrambled the display of writing on the page I pulled up.
I was doing a google search for a Gallery website.
Please give me some Firefox Fixes For Dummies level advice that will help me get my favorite browser back. THANK YOU.

Hi Suzy Q,
I can send and receive calls.
I get "messaging stopped" when doing a lot of texts.
Texts come up "ghosted" meaning they have the text on the bottom and a transparent one overlaid on top. they then become one. But I get the ghosting most of the time when I go into a message from a contact to send a text.
When I go to call logs or text logs, the numbers come up first, and then then the names pop up randomly, meaning not in order down the page, until they are all shown. lots of lag time.
It runs slow.
I have 5 apps on here. I should be able to have a lot of apps on here, and play music, and have files, and...and....and.
I can get online but doing a Google search, when the page with the choices comes up, it is blurred and I have to tap on the screen for it to become clear and readable.
When online and scrolling, it hitches sometimes/lags/gets stuck then unstuck
I get VZWAVS has stopped. (not sure if those are the right letters)
The status bar that is supposed to be gray with the new update, goes back and forth between green--the old os--to gray. And I have found no continuity with when I get green or when I get gray.
I get a black screen on occasion.
sometimes the proximity sensor doesn't work.
sometimes when I have my bluetooth on and have "hands free mode" on, I get the a text message read through the headset and also through the handset.
I soft reboot often--turn it off wait a bit and
