FireFox hangs up for a long time on most pages and sometimes never loads them. This is new phenomenon. What can I do to resolve this issue?
I attempt to open up a site. Firefox hangs for a 20-30 seconds on most sites and sometimes never opens the page, despite leaving it open for a long, long time. I find that if I go up to the address bar and hit "enter" on the page I'm trying to go to that most of the time I can then load the page after a couple of tries. This is obviously annoying and never used to happen. I'm looking for a fix. Thanks!
I had done that already. I brought it down to 30, which was recommended in another thread.
For most sites, Firefox works fine. But some of the primary sites I use for work hang up for long periods of time and frequently never load. I've tested the same sites with other browsers and they load quickly, so it is a Firefox issue.
Please help me keep Firefox! Thanks!!

Thanks Nubz
I will review further an correct myself.
The last reads the way I meant as in physically getting to see it.
I am not sure you are reading it the same way.
As a consequence your suggestion seems a bit ambiguous to my mind.
Thanks for the input. I will read a digest context a bit more and see if I can rephrase.

SQL with connect by prior running for a long time
Hi,
We are using Oracle 10g. Below is a cursor sql which is having performance issues. The pAccountid is being passed from the output of a different cursor. But this cursor sql is running for a long time. Could you please help me in tuning this sql. I believe the subquery with connect by prior is causing the trouble.
The TRXNS is a huge table which is not partitioned. The query is forced to use the index on the accountid of the TRXNS table.
The accountlink table has 20,000 records and the TRXNStrack table has 10,000 records in total.
This sql executes for 200,000 pAccountids and runs for more than 8 hours.

Dreamweaver script running for a long time issue
Hi there,
having a recurring problem with the BC extension for Dreamweaver. Using Adobe Cloud CS6 and a mac. I get the following error message whenever the BC extension is open, and really the best way to get rid of it is to close the extension. I've googled the issue and there's a few things relating to other .js files, but I'd like to avoid having to reinstall CS6 if I can!
Error msg:
A script in file Macintosh HD:Applications:Adobe Dreamweaver CS6:Configuration:Shared:BC:JS:bc_sites.js has been running for a long time. Do you want to continue?Hi
This might help: http://helpx.adobe.com/dreamweaver/kb/re-creating-dreamweaver-user-configuration.html
Give it a try and let me know if you still experience the same issue. The article is a little old, so you'll have to adapt the links there to your current install (C:\Users\your username\AppData\Roaming\Adobe)
Kind Regards,
Alex -
I've used an older version (3.?) of Firefox for a long time. I had loads of bookmarks. I downloaded the new Firefox 4. It won't open and the older version is now gone. I use a Mac with a 400 MHz PowerPC G4 with 1.12 GB SDRAM and a 60 GB Internal Hard Drive. I'm running Mac OS X Version 10.4.11. I really need to recover the older version of Firefox or make the new version work.
Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html -
I have been using firefox for a long time, today when i tried to launch firefox i recieved "Firefox is configured to use a proxy server that is refusing connections." i dont know how to fix this. I didnt change any settings, im the only person who uses this computer

If you do not need to use a proxy to connect to internet then select "No Proxy"

For a long time now, every time I've tried to log in to ebay (I can get into ebay, but I cannot log into my account, etc) or Paypal (I cannot even access this site), I get an error message stating that "the connection is untrusted" "You have asked Firefox to connect securely to signin.ebay.com, but we can't confirm that your connection is secure".- I've tried the standard solution i.e. resetting the time and date on my computer, but still this does not work.
Please help as this is severely restricting the use on my computer - and it's frustrating as hell!
Many thanksTry to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.
If that helped to solve the problem then you can remove the renamed cert8.db.old file.<br />
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.<br />
Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.
If that didn't help then remove or rename secmod.db (secmod.db.old) as well.
You can use this button to go to the Firefox profile folder:

My iMac (running Lion 10.7.3) is connected wirelessly to a Laserjet 2550. This has operated fine for a long time, but now the printer cannot be found when Time Machine back ups are taking place - Bonjour does not show any devices being available when Time Machine is running. Does anyone know the cause & remedy please?
Your points match mine pretty well,though here are some thoughts:
1. I thought about this theory myself this morning (iTunes possibly causing more issues), but I haven't been able to verify it.
2. When I set up a new user it seemed better for a while, but the issue croppped back up. Yesterday I fully wiped the machine and reinstalled from scratch. I did not reimport my user from TimeMachine, but the problem has come back. My thinking was that I might have some really old software or prefs hanging around causing the issue. No dice.
3. This is my current theory of the issue, so my next step will be to pull the RAM from Crucial and see how the system behves. IF that doesn't eliminate the problem, I'll pull the factory installed RAM and replace it with the 3rd party RAM. The odd thing is how many people seem to have similar issues - I know two personally, and have seen several posts on forums. I think the most common point for this happening was the 10.7.2 update, which would point to software as the culprit.
4. That matches my experience.
My hope is that this will be repaired in the forthcoming 10.7.3 release (current production version is 10.7.2), but otuside of what I noted above, I'm at a loss. -
In Adobe Acrobat 9 which I have been using for a long time (Widows 7) says, You cannot use this prod
In Adobe Acrobat 9 (Wndows 7) which I have been using for a long time now it says I cannot use it withoutv repairing. It instructs me to uninstall & reinstall...
I have not run into this yet with my AA9 and Win7, but have been seeing posts about it. I would try a repair before I would do an uninstall and reinstall. You might also turn off javascript for a bit in case there has been some javascript that has caused problems (ok, making wild guesses). If you do decide to uninstall, be sure to deactivate first, uninstall, run http://labs.adobe.com/downloads/acrobatcleaner.html, and remove any left over parts of the Acrobat folder. Then proceed to the reinstall and updates.
There is a question about whether being able to use it is correct, or you are just getting some message that is a spam that somehow got into your system (again, a possible javascript issue). Besides turning off javascript, you could also try isolating the javascripts to moving them to a temporary directory and seeing if one is causing the problem. -
Slave instance can not synchronized with the master for a long time
Hi,
Slave instance can not synchronized with the master for a long time, and the gap of LSNs between slave and master are more and more larger. The transfer bytes per second between master and slave is 118MB/s , upper limit to the ethernet card. Why???
ENVIRONMENT:
1. A network program which we called mcdb is based on BDB 4.8.30. It is used to accept get/set requests and then query data from bdb or save data to bdb.
2. mcdb implements replication with bdb replication manager api. The default start replication policy is DB_REP_ELECTION, rep ack policy is DB_REPMGR_ACKS_ONE_PEER and rep priority is 100.
3. The bdb data files, bdb log files, region files and rep files are all in the same home directory.
4. There are two instances of the mcdb are separately on two standalone servers which has no other programs. These two instances are in one replication group which can elect a master automatically.
5. The master instance is online, which has lots of requests (get, set, delete).
ACTIONS:
1. Start two mcdb instances on two servers and the two instance make a replication group. Slave has already synchronized with the master.
2. Stop the slave for a long time (more than 20 hours).
3. Start the slave instance to synchronize data with master.
RESULT:
1. the gap of LSNs between slave and master are more and more larger.
2. db_stat of master and slave:
master db_stat:
467170 Number of PERM messages not acknowledged
9245 Number of messages queued due to network delay

Edited by: 899585 on 2013-1-4 下午10:55Hi,
Unfortunately, this issue is beyond the level of what is supported over the forum. Performance related issues are extremely complex and require an in-depth understanding of your environment and dedicated support. In a generic sense, you can look at this as a basic queueing problem. You have a server that went down and work is still coming in. When the server gets started it is possible that it may never catch up depending on new work coming in and the rate at processing the old work.
So what would you do in this case --- one thing would be to reduce the new work coming in. In HA terms this would be slowing the master down and you can increase DB_REP_ACK_TIMEOUT for this. Another thing you could do is add fresh servers to help reduce the workload. In HA terms, this would be the equivalent of restarting the client and give it a fresh look at everything. Another thing you could do is replan the system and load balance. In HA terms, it would mean something like take a hot backup of the master and reinit a client from scratch.
If you are interested in getting a dedicated support person working on this concern, please let me know and we can move forward down that path. Just respond to the thread with your email address and I will get in contact with you so we can pursue that approach.
thanks
mike
