AR8 freezes for about 40 seconds after start

Hi,
I use SuSE Linux 10.0 on a Thinkpad R51 and I installed the 8.1.1 enu rpm version of adobe reader and I use a dual head xinerama display.
Biggest problem:
Adobe Reader starts up normally and for about 2 secs, it can be used normally. Then, it freezes for about 40 seconds. Nothing is possible in this time. Afterwards, a normal use is possible.
Minor problem:
Everytime I open a PDF document with the Firefox plugin (FF 2.0.0.6), the plugin seems to be loaded and initialised again. This is very time consuming. In AR7, one had to wait for plugin initialisation only when opening the first pdf document.
Is there a plan to fix these issues? Otherwise, I will downgrade to AR 7.0.
Thanks,
Al

Hi Al,
Could you answer the following questions in regards to your problem, for us to better understand the problem scenarios -
Regarding your first problem ---
1. The freeze after launch is happening on "every" launch of the reader, or is it occassional?
2. When the reader window is hung, do you see any sort of progress bar or alert on the screen?
3. If you try to launch the the reader from the terminal, do you see any alert/warnings on the console while the reader is hung?
There is also a small exercise we would like you to do, in order to verify a known issue (you would need 'root' access to do the following) -
* Temporarily rename the folder "/usr/X11R6/lib/X11/fonts" (the font folder under /usr/X11R6) to something else (say "/usr/X11R6/lib/X11/fonts_dummy").
* Restart acroread a couple of times.
Do you still see the problem of the application getting hung? Please do let us know your observations. Also don't forget to restore the name of the folder "/usr/X11R6/lib/X11/fonts" back to its original name.
Regarding your second problem ----
The behaviour is basically due to the browser's handling of external plugins. In Reader 7.0 due to some issues, we sometimes missed indicating to the browser that our work was done, and that is why an instance of the plugin persisted.
This was however corrected and in Reader 8 we now correctly tell the browser when the PDF file is closed. It is at this point that the browser should decide whether to keep the plugin loaded or to close and unload it. And it seems that at present Firefox immediately unloads us after the last document is closed.
Anyway thanks for pointing out the problem. We'll take note of it and try to find a workaround to improve the performance in the future release.
Regards
Salil

Freezing for a few seconds after switching tabs, freezing for a second without doing anything.

Hello
I use Firefox v. 25.0 (If i remember correctly I had this problem at 24 too) and I my browser freezes for a few seconds, maybe every 10 seconds. It only freezes for about give or take, 3 or 4 seconds but it is starting to bug me.
I have tried
-> Safe mode - still happens in safe mode.
-> Restarting firefox (multiple times) - The last few restarts I have removed/disabled any add ons or extentions. It always starts with out the freezing, but maybe after 1 or 2 days the freezing comes back again. This time I'm just half way done with it so I haven't bothered to disable much.
-> Checking for multiple duplicated files in the firefox folder - didn't have any.
I apologize that this is a commonly asked question, but I wanted to see if I could get any help here before having to move to chrome (which is not recommended from my sister), or internet explorer (which is in my recycle bin...)
Thank you in advance.

Although your IE shortcut might be in the recycle bin, you'll still want to have IE installed for those special sites that only support IE...
Do you usually have a lot of tabs open? By default, Firefox updates the file which stores open windows and tabs every 15 seconds. The larger this file gets, the longer this takes. A major overhaul was made for Firefox 25 to make this more efficient, so this might not be your issue, but you can stretch the interval out to 60 seconds and see whether that makes a difference. Here's how:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box that appears above the list, type or paste '''session''' and pause while the list is filtered
(3) Double-click '''browser.sessionstore.interval''' and change the value from 15000 to 60000 (this value is in milliseconds: 15000/1000 = 15 seconds, 60000/1000 = 60 seconds). I don't know whether this takes effect immediately or the next time you start Firefox.
Does that help?
If that doesn't make much/any difference, have you set up Firefox Sync?

IMac freezes for a few seconds after external hard drive wakes up

24-inch iMac, early 2008. 4GB RAM.
I hear my external hard drive spin up as if it's been not spinning (totally possible; I only use it for Time Machine backups and iMovie archive storage)
During this spin-up process, my iMac (Mountain Lion, latest version) freezes momentarily--keyboard, mouse, screen--but audio remains faithful and music keeps playing.
After about 5 seconds of this delay, the thing catches up with itself and everything I was doing during the freeze gets processed and displayed. (e.g., I may have been typing a sentence and didn't hear the disk spin up at first; once the disk "comes back to life" everything I typed appears on screen as if everything was being typed really quickly--as if my keystrokes were just delayed while the disk spun up.)
Anyone know what's going on or have a solution to this annoying problem?
I'm comfy with the Terminal if any uber geeks want to take a crack at it.
Thanks!

go to apple logo > system preferences > spotlight
then
there are two tabs
choose "Privacy"
drag the external into the spolight privacy section
OR
hit the "+" at the bottom left > navagate to the external > and choose it
whats happening is that spotlight indexes when you turn it on and potentially slows the computer down
also
if it is a Time Machine backup it is pointless as Time Machine mirror images your internal drive to the external
meaning
spotlight has two of the extact same files and folders it has to organize
aka
pointless
let me know how it goes

Yesterday I installed "Mavericks" on my two identical machines (office and home, iMac i5 27'' late 2009) and now the cursor freezes for a few seconds after quitting an application on one machine and the the track pad stucks with safari - unsatisfying!

Even the back and forward buttons do not work than. Allover the complete installation process went different on both machines. One started the installation twice immediately after completion. I dont know what's wrong, I never have had such a trouble with Mac OS. I can't help myselfe an I am highly disappointed about Apple!
Markus

After a few Google searches and a few downcasted days, I had to realize that I have to apologize to Apple, it was seemingly not alone their fault.
All trouble makers to Mavericks are accumulated in my environment:
External WD hard drives get in conflict with the nem Mavericks OS X, as well as drivers software from Logitech (LCC), which all is in use with my system.
Delete the WD software of external hard discs and uninstall (use uninstaller) the Logitech control center (LCC) and all is fine again.
Have fun with Mavericks, a just started to love it....

Firefox freezes for around 10 seconds when loading a video on YouTube

So everytime I'm loading a video on YouTube, it takes a very long time to load (10-15 seconds) and while the video is loading Firefox becomes completely unresponsive. I can't do anything until the video is loaded, and when it takes such a long it becomes annoying.
I have the newest versions of both Firefox and Flash Player.

Does this happen with other browsers as well? If no, maybe an extension is interfering. Here is how you can disable them to test that: https://support.mozilla.org/en-US/kb/Uninstalling%20add-ons#w_how-to-disable-extensions0-personassf-and-plugins

Whenever I use the Flash plugin to watch videos, for example Youtube, my firefox freezes for about 5 seconds, then continues to function as normal. This only happens with videos and only in Firefox.

I need help to fix this problem, I've tried re-installing Firefox and flash, but to no avail.

Anyone?

Firefox freezes for a while when the Downloads window pops up

Whenever I start a file download (regardless of its size), Firefox freezes for a few seconds, sometimes longer. I deleted the downloads.sqlite file and it helped for a few days but it started happening again. I deleted downloads.sqlite again but this time it wouldn't help at all. I even installed DownThemAll add-on as some people suggested but it happens with it too.
I've been using Firefox for 7-8 years now and never had any issues that could not be resolved but this plus some other freezes or crashes from time to time is starting to be annoying. I have all major browsers installed because of my work but kept FF as default one but I'm starting to consider a switch after all these years.
Can anyone suggest a soluton? And I don't consider disabling the Downloads pop-up window a solution.
Win 7 64bit

Thanks for your input but I already said that I deleted downloads.sqlite.

Firefox freezes for a period of time when I try to fill out online info

When I begin to fill out forms on line, the first few letters show up but then Firefox freezes for 15-60 seconds before the next letter is entered and does this with all of the letters I entered after thel initial freeze which is just what happened. I have therefore gone to typing the information in Notepad and then paste in the appropriate area which is what I am doing now. However, outside of Firefox the rest of Windows 7 is responding. I thought it might have been a problem with my keyboard but after contact with Logitech and there recommendatons which did not work, I believe it is a problem with either Windows 7 and/or Firefox. I have not used IE yet so at this point I do not know if the problem exists there.

You can check for problems with the sessionstore.js file in the Firefox profile folder that store session data.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Multiple_profile_files_created
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Trackpad/Cursor Freeze for a few seconds

Some months back, I bought a 11" MBA to my wife. I have continuously update it and installed all available updates, and now we have problem with the Tackpad freezing for 2-5 seconds after not touching the pad for about 1 minute. (this was not a problem when she first got the machine)
Really irritating when browsing / reading and we take our fingers away from the machine and just read, and then when we want to scroll or click something there is no responds for a short period.
What to do?
(have searched in this forum with no success)
OS X 10.8.2, 1.7 Ghz MBA

For me it was com.telldus.service.plist in /Library/LaunchDaemons that caused the problem.
Log in/switch to an administrator account
open Terminal
sudo rm /Library/LaunchAgents/com.telldus.service.plist
Other has reported that removing these also helped:
sudo rm /Library/LaunchAgents/com.google.keystone.agent.plist
sudo rm /Library/LaunchDaemons/com.google.keystone.daemon.plist
I found this solution here

After I type in my login details and press "enter" on a website, Firefox freezes for around half minute.

After I type in my login details and press "enter" on a website, Firefox freezes for around half minute. This has gone on for around 5 months. I've tried disabling add-ons to my Firefox but they don't seem to affect this problem. My version is 17.0.1.
How do I combat this problem? Many thanks in advance.

Provide the website name.
'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''
''(If you're not using it, switch to the Default theme.)''
* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Don't select anything right now, just use "'Start in Safe Mode"''
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again.''
'''''If it is good in the Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one.

Firefox frequently freezes for 30-60 seconds when I click on bookmarks, bookmark buttons, almost anything really.

Firefox frequently freezes for 30-60 seconds when I click on bookmarks, bookmark buttons, almost anything really. It has been doing this ever since I downloaded the latest update (7.0.1). It is really frustrating. Can you please help?

You will also notice that your shift key will be emulated. Meaning that keys you will try to press will press but they will act like you are pressing the shift key when you are doing them.
Try this, minimize the firefox window by pressing the tab on your taskbar. After doing that maximize it again. You will magically be able to click any link on your page. When you navigate to a new page however, the entire situation will start all over. My only remedy is rebooting and hoping it doesn't happen again soon.

Firefox v15 and up cause my computer (MAC OSX 10.8.2) to freeze for about 30 seconds every 15-30 seconds and forces me to turn it off with the power button

Firefox v15 and up cause my computer (MAC OSX 10.8.2) to freeze for about 30 seconds every 15-30 seconds and forces me to turn it off with the power button. It only causes this after I have opened Firefox, my computer runs fine before opening Firefox. I have uninstalled Firefox and cleared my personal settings. I have installed future updates (16 and 17) and have run into the same issue. I cannot pull any information on RAM or CPU usage because when it happens it makes my computer unusable. Unfortunately I need to use FF for work and can't. I have tried the different responses on the forums to reduce the amount of RAM and CPU usage with no change in performance.

Firefox freezes for at least 5 seconds when opening context menus

Well I've been looking for a reason to switch to Chrome... I guess now i have one.
Problem: Firefox freezes for 5 seconds when opening context menus (screen goes gray for @3s)
Firefox 32
Ubuntu 12.04
I first noticed it this morning when I tried to open up a Bookmark menu. Continued testing and found that right-clicking(anywhere) caused the same behavior. There are tons of posts going back years of similar behavior (although I doubt they're all related), so I ran therough the standard troubleshooting steps (restarting firefox after each step):
* cleared the caches
* Lowered cache memory allocation
* Created a new profile (did not carry-over any previous bookmarks or add-ons)
* Restarted firefox in safe-mode.
* Reset firefox (from safe-mode command)
Restarting firefox with all add-ons disabled is not included here because that is assumed in 'created a new profile' (correct?).
Furthermore, when I went to reinstall I got the error: "E: I wasn't able to locate a file for the firefox package. This might mean you need to manually fix this package."
I don't know what happened over the weekend, but I guess I'll try a full manual reinstall, when I have more time to mess with it. FF has been a primary tool for development, but for now it's dead to me.
P.S. On an unrelated issue. Maybe I'm old-school, but I miss the original drop-down menus up top. I don't think there's anything wrong with improving on the existing model, but why would you replace something that's worked well for DECADES.

Thanks for your response and sorry for the delay in my rep[ly.
Today I tested the Linux-64 version (Firefox 33) from the link you suggested. There weren't any install instructions or a README, but based on the file-system layout I guess it just needs to be extracted. I downloaded and extracted to my Downloads directory and ran the executable via command-line as my user (not root).
Firefox popped up right away, but it was not usable for at least 30s. It asked to import from Chrome which I did (no errors). Every click on the top bar (address bar search, buttons to the right of search, bookmarks toolbar) resulted in a dimming un-dimming sequence of @7s, after which nothing (couldn't focus in the address bar, occasionally the bookmark menu would appear, but was not functional). Basically, it's un-usable.
As I mentioned in an earlier reply, I am having similar problems with Komodo which is apparently also Mozilla based.
Are there any logs I could tail and post that might help track this down?
Not sure what to do at this point.
