Why is Firefox slow after latest update?

I just updated to v24 and it is really lagging a lot. I've tried resetting, disabling add ons, updating add ons, restarting in safe mode... the whole nine yards. I've done every troubleshooting I can think of and it is still really laggy and slow. I have Windows 7 and a 64bit system. I didn't have this problem until the latest update.

This always seems to happen with updates. They fix a bunch of bugs, but create new ones, or don't fix old persisting ones. I was under the impression that Firefox speeds up with every update, but it would seem to be the opposite. I am perturbed that users have to jump through hoops to find workarounds. eg. Things were working just fine before, now that it isn't after the new update, we have to delete old user profiles, dig through subfolders to find duplicate files created to delete, and restart from scratch. Which can take hours of your time. All because Firefox messed things up. If Firefox broke it, they should fix it. Not us, we don't get paid to do their job. I'm always for "if it's not broke, don't break it, so you don't have to fix it." Also what's the point of having a "hardware acceleration" feature, if it doesn't work?

Safari super slow after latest update to 10.9.1. Please help. Thanks.

My internet is deathly slow after doing the update. Any advice? Other programs seem fine. Thanks, Yvette

Hi yipck,
Thanks for visiting Apple Support Communities.
I recommend starting with the tips in this article if Safari is loading web pages slowly:

My mac has become very slow after latest update of yosemite

i have installed the latest update for yosemite and my mac is extremely slow. Its i5 2013 model. help please?

When you see a beachball cursor or the slowness is especially bad, note the exact time: hour, minute, second.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above.
Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first.
Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

AE CC Slow after latest update?

I've noticed since the most recent CC update that AE is really unresponsive. Long delays to clicks. Saves take a few seconds. Nothing changed on this editing station but the AE CC update.
Win 7 64bit Pro
32GB RAM
2GB Nvidia
USB3 drives
Same as always, nothing changed as I said. Please, forgive my sounding like a complete jerk, don't try to send me in the "chasing the tail" stunt on this one with "have you tried blah blah blah on the workstation bit". The only thing that changed was the AE update.
What happened? I've checked with other users who are reporting the same issue since this update.

Thanks Todd.
Updated to latest. Did testing. There's obvious improvement in the dropdown menus performance. However, there's no improvement in parameter controls on native AE effects (Hue/Saturation for example). Key entry and slider interaction show a consistent 6-7 second lag between activation to update (some 10-15 timed tests across multiple parameters). We've tested this across multiple native effects on basic layers (image, solid, adj, etc.).
Our verdict:
Partially addressed, at menu level. Thank you very much for this.
No change in parameter controls and screen refresh. Appears independent of resolution setting (full, half, quarter, etc.) and preview mode (adaptive, fast, etc.).
Our testing was done in brand new projects and across multiple new comps on the latest update using only AE native presets.
Hope this helps.
Best,
Tobias
p.s. I forgot to mention that the lag mentioned above was also tested on layer parameters, (position, rotation, etc.). Same results.

Multicam editing in Premiere Pro CC very slow after latest update.

So I installed the latest update for Premiere Pro CC a couple of days ago and now every edit I make in my Multicam sequence takes about 10 seconds to take effect. No matter how small an edit I make. While it´s taking affect the computer just freezes.
Is it possible to downgrade or does someone have a sollution?

@Devinclk: You specify that you're on 7.2. If that's accurate, then please update to 7.2.2. Among the many bugs fixed were several involving multicam.
@Mediatek: first off, as a CC subscriber you most certainly do have access to the CS6 version of PPro. On this download page, use the drop-down under "In This Version" midway down the left side of the page to select CS6, then click "Download." As to the problems you're having with CC, if you start a new thread and provide as much detail as possible, there's a good chance someone around here will be able to help troubleshoot it. Remember, while you're choosing to emphasize that you're "another struggling CC user," tens of thousands of customers are using the program without such problems. So there's a particular issue--or confluence of issues--causing particular problems in your case. The first step to resolving the problems is for you to share specific & thorough enough information for someone to help.

Safari slow after latest update 1-27-15

After updating my mac on with the new updates released on 1-27-15 Safari is almost unusable. It is so slow and hangs there indefinitely. It is not my internet service as things are running fine with all other devices - just my desktop where I updated. I have had to switch to Firefox for now so I could even write this. Please advise on a solution as Safari is my preferred browser so that all my apple devices can share info.

Security Update 2015 - 001 Ver. 1
Safari - 7.1.3
Remote Desktop Client Update 3.8.2
Those were the updates that were suggested as released on 1-27-15. After doing so, Safari is just about unusable.

ITunes running super slow after latest update, today.

I just updated my software on iTunes and suddenly it's running super slooooooow!
It takes about 2 to 4 minutes to open.
New computer. Running Windows 7. It's not my computer. I promise.
iTunes was super fast until I just updated the software, this morning.
Plus, now it doesn't recognize my iPhone 4.
All of other programs are still running at lightening speed.
So, any suggestions? I'm expecting my new iPhone 4s, today and really don't want to have any issues going in.
This is very frustrating!
Thanks!

Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

Why is itunes crashing after latest update

I recently updated iTunes on 2 windows 7 PC's and the app keeps crashing after a few seconds after starting the program.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT as you start iTunes) then going toEdit > Preferences > Store and turning off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.
You could also try working through

Alternatively see the second entry in the Further Information section for tips on rolling back to a previous version of iTunes.

You Tube not playing video on Firefox with Adobe Flash after latest update

You Tube and other sites are not playing video on Firefox with Adobe Flash after latest update for both. Adobe Flash is working on other sites but not You tube and those sites that may have embedded You Tube videos, I'm not sure.
Adobe Flash does not crash and no error message is showing. All that shows is a dark screen for the Flash video. Right clicking the screen shows only a non-clickable 'Movie not loaded' and the clickable link to the Adobe home page.
I have spent an hour trying things as suggested for past problems similar to this but none have helped.
I have sent sad face letting you know what I think of the latest update because of this which says pretty much the same thing as I have said here.
I have no further info but if I had some input and queries form you I might be able to provide more.

I'm not sure how to remove the 12.xxx version,. I don't understand why it is there, usually updates over wirte the old one as far as I know. I don't know where to find it.
pref .js deleted.
I could not find a user.js
I disabled hardware acceleration on one of them, not sure which and I don't remember how I did it but think it must have been on the flash.
No idea what protected mode is
no new profile, I've never done this.
Ok, did what you have said as much as I could. I have been fidgeting with things now for a couple hours. After doing a CCleaner and Registry cleanse, turning off and restarting the computer, the videos are now p-laying.
I would still like to know how to find and get rid of the duplicate Flash plug in though if you would't mind.
Thanks for the help.

Leopard slow starting up after latest update

My MAC Pro is very slow starting up after latest update. Before it took 15 seconds and now takes approximately 8 or 9 minutes. There is a blank blue screen for the entire time, i have repaired disk permissions but this has not helped either. Can any one suggest anything else.

Download an appropiate utility such as Onyx, etc., and purge all caches, user and system. Also do an [SMC reset|http://support.apple.com/kb/HT1411] and a [NVRAM reset|http://support.apple.com/kb/HT1379]. When you repaired permissions, you also repared the disk itself, right?

Netflix will not play on my Mac anymore after latest update...HELP!!

After latest update, Netflix will no longer play. When I select a movie, it prompts me to install Microsoft Silverlight, which I have repeatedly done. Netflix claims the latest MAC update is to blame, not a Netflix issue....PLEASE, any assistance is greatly appreciated.

Slowdown of safari after latest update ?

Anyone have the same problem with Safari after latest update: very slow especially when downloading images ?
MacBook Pro Retina 15"
Yosemite 10.10.3

There are many possible causes for problems with web browsing. Below are some simple steps that may help either to solve the problem or isolate the cause.
Back up all data before making any changes.
1. Restart your router and also your broadband device, if they're separate.
2. If you connect to the the router with Wi-Fi, turn off Wi-Fi and then back on.
3. If you connect with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi.
4. If your browser is Safari, then from the Safari menu bar, select
          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If the Downloads button (with the icon of a downward-pointing arrow) is showing in the toolbar, click it and then click Clear in the box that appears. The download history will be removed.
5. Select the Extensions tab in the Preferences window. Turn all extensions OFF and test. If there's an improvement, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
6. If you're running OS X 10.10 or later, select the Search tab. Uncheck the box marked
          Enable Quick Website Search
if it's checked.
7. If you're running OS X 10.9 or later, select the Advanced tab and uncheck the box marked
          Stop plug-ins to save power
Quit and relaunch the browser.
8. Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest.
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
9. Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
10. If other browsers and Internet applications are also affected, follow these instructions and test.
11. If Parental Controls is active for any user, please turn it off and test.
12. Open the iCloud preference pane and uncheck the boxes marked Safari and Photos, if they're checked.
13. Are there any other devices on the same network that can browse the Web, and if so, are they affected?
14. If you can, test Safari on another network.
15. Start up in Recovery mode. In the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. While in Recovery, you'll have no access to your saved bookmarks or passwords, so make a note of those before you begin, if they're needed for the test.

Everything is so slow after I updated to 10.7.2...Help:(

I have a Macbook pro 15''.. Bought this Aug.
Everything is so slow after I updated to 10.7.2 .....
Especially now it takes me 1 min to turn on my laptop... which used need only 10 sec. So does Turn off...before update it is 2 sec, now it is 30 sec...
What should I do to make it faster?
Thanks.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software -- potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions -- they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are four lines of text in monospaced type, which are UNIX shell commands. They’re harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of running these commands, search this site for other discussions in which they’ve been used without any report of ill effects.
Some of the commands will line-wrap in your browser, but each one is really just a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
To begin, launch the Terminal application; e.g., by entering the first few letters of its name in a Spotlight search.
Step 1
Copy or drag -- do not type -- the line below into the Terminal window, then press return:
kextstat -kl | awk ' !/apple/ { print $6 $7 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
This time, you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Step 3
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Step 4
ls -1A {,/}Library/{Ad,Compon,Ex,Fram,In,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Sta}* 2> /dev/null
Important: If you synchronize with a MobileMe account, your me.com email address may appear in the output of the above command. If so, change it to something like “[email protected]” before posting.
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
You can then quit Terminal.

After latest updates cannot stream from iPad to AppleTV

After latest updates on my New Ipad and Apple TV 2nd Generation, Canot stream video from the iPad to Apple TV.
I Can Stream from my iMac and from MacBook Pro, but not from iPad.
Any Advise?
Thanks.

Hey guys, unfortunately I've had to re-install Mountain Lion to get rid of the issue, but here's my experiences after trying many things and contacting AppleCare...
First, I had Lion and had upgraded to ML. They had me go do the following with limited success:
1) Reset PRAM (no effect)
2) Recovery Disk and repair permissions (no effect)
3) Went to system /Library and User /Library and basically we went through several attempts at removing various files from (/Library/InputMethods, /Library/LaunchAgents, /Library/LaunchDaemons") Once I had essentially removed every file and dragged it into the trash (without deleting), the issue was resolved. So, it seems to point to an application that was not fully supported or giving problems within the ML environment. The plan was to drag them one by one back and do reboot/shutdown until I could isolate the application, but rather than do that, I just did a fresh install to take out any variable that could be present from having to do a Lion/ML upgrade. I was able to put a fresh copy of ML on the computer through the Recovery partition after establishing connection to my router. Everything is working fine now.
Anyway, hope that helps some of you. It was a frustrating experience but seems to point to application issues wih the OS and not the OS itself. I think developers are still rushing to catch up with full ML support and so you might find yourself having many new updates in drivers or applications over the next month.
