How many tabs can I open at a time when using Firefox 3.0.5 with Windows Xp?

I tried to open 25 tabs in one window using firefox 3.0.5 with windows xp. It would only let me open 10. Tabs I added after 10 were added, but tabs at the begining were erased. What do I have to do to open all the tabs that I may need without changing the firefox or windows version? Do I need to open a new browser window for every 10 tabs?

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes). 
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]] 
 
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. 
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions. 
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

How many apps can be open at one time?

My friend did not know how to close apps. I showed her and was shocked at how many she had open at one time. Everything since she got her ipad over a year ago. She must have had 30 games, pictures, internet, lists, contacts, mail, video, everything was open.
It made me curious if there is a maximum number that can be open at one time, and if at some point will they automatically close themselves?
Thanks

Open apps consume almost no resources, unless they run background refresh. Once they have been inactive for a while, iOS writes the current state back to storage, to free up RAM for other processes. You can see this when some apps, particularly big heavy games like Infinity Blade, relaunch from the starting splash screens instead of taking up precisely where they were left.
It's still good practice to close down stuff every so often, but not necessary, as you've discovered.

When using Firefox 3.6.6 with Windows 7 operating system, Windows will close Firefox. How do I fix this?

I am using Firefox 3.6.6 on a Windows 7 PC. About once a day. I get a Windows error message saying that it had to close Firefox. How do I fix this? I have toolbar for Firefox, Google toolbar for Firefox, Java Console 6, Java Quick Starter 1, OneClick YouTube downloader. StumbleUpon 3.64, and Trend Micro Toolbar 1.6.0.1126

Start Firefox in [[Safe Mode]] and go to '''Tools->Addons->Extensions''' and try disabling Trend Micro Toolbar.
Sometimes AV softwares install certain toolbars that mess with Firefox configuration settings

How many meetings can be opened by one account at the same time?

I've tried Adobe Connect trial version.
There are few questions about the product.
1.How many meetings can be opened by one account at the same time?
   I could open 9meetings at the same time using other PCs. What is the limit?
2.What is the maximum of students in a meeting?
   I'm thinking of buying monthly/Individual product.
3.The meeting never end even though host is out of it. But we want to control.
   Can host close a meeting so that all participants are out of the session?
Thanks for your attention.

This depends on your licensing.
If you are using a Named Host license, then you can open one meeting at a time. If other members of the Meeting Host group are present in a room, then it should allow you to have multiple rooms open, one for each Meeting Host licensing being used.
If you are using the Concurrent Learner license, then each meeting you join uses a different licenses, so as long as you have concurrent seats available, you can open as many rooms as you want/need.
Maximum number of attendees (students) would be your room's concurrent maximum, less your self. The monthly version of Connect offers 25 concurrent attendees in each room, so that would be 24 students and you.
The meeting does end after it is dormant (no host) for ~15 min, however you can use the End Meeting function (Meeting > End Meeting) to close the meeting and remove everyone, including yourself, from the room.

How many databases can be opened simultaneously in a single file?

To all:
I don't known how many databases can be opened simultaneously in a single file. After my application open 499 databases in a single file simultaneously, DB->open return error 12.(can not allocate memory ?).
How can i do ? Thanks.

I found it:
Berkeley DB Reference Guide:
Locking Subsystem
PrevRefNext
Configuring locking: sizing the system
The lock system is sized using the following three methods:
DB_ENV->set_lk_max_locks
DB_ENV->set_lk_max_lockers
DB_ENV->set_lk_max_objects
The DB_ENV->set_lk_max_locks, DB_ENV->set_lk_max_lockers, and DB_ENV->set_lk_max_objects methods specify the maximum number of locks, lockers, and locked objects supported by the lock subsystem, respectively. The maximum number of locks is the number of locks that can be simultaneously requested in the system. The maximum number of lockers is the number of lockers that can simultaneously request locks in the system. The maximum number of lock objects is the number of objects that can simultaneously be locked in the system. Selecting appropriate values requires an understanding of your application and its databases. If the values are too small, requests for locks in an application will fail. If the values are too large, the locking subsystem will consume more resources than is necessary. It is better to err in the direction of allocating too many locks, lockers, and objects because increasing the number of locks does not require large amounts of additional resources. The default values are 1000 of each type of object.
When configuring a Berkeley DB Concurrent Data Store application, the number of lock objects needed is two per open database (one for the database lock, and one for the cursor lock when the DB_CDB_ALLDB option is not specified). The number of locks needed is one per open database handle plus one per simultaneous cursor or non-cursor operation.
Configuring a Berkeley DB Transactional Data Store application is more complicated. The recommended algorithm for selecting the maximum number of locks, lockers, and lock objects is to run the application under stressful conditions and then review the lock system's statistics to determine the maximum number of locks, lockers, and lock objects that were used. Then, double these values for safety. However, in some large applications, finer granularity of control is necessary in order to minimize the size of the Lock subsystem.
The maximum number of lockers can be estimated as follows:
* If the database environment is using transactions, the maximum number of lockers can be estimated by adding the number of simultaneously active non-transactional cursors open database handles to the number of simultaneously active transactions and child transactions (where a child transaction is active until it commits or aborts, not until its parent commits or aborts).
* If the database environment is not using transactions, the maximum number of lockers can be estimated by adding the number of simultaneously active non-transactional cursors and open database handles to the number of simultaneous non-cursor operations.
The maximum number of lock objects needed for a single database operation can be estimated as follows:
* For Btree and Recno access methods, you will need one lock object per level of the database tree, at a minimum. (Unless keys are quite large with respect to the page size, neither Recno nor Btree database trees should ever be deeper than five levels.) Then, you will need one lock object for each leaf page of the database tree that will be simultaneously accessed.
* For the Queue access method, you will need one lock object per record that is simultaneously accessed. To this, add one lock object per page that will be simultaneously accessed. (Because the Queue access method uses fixed-length records and the database page size is known, it is possible to calculate the number of pages -- and, therefore, the lock objects -- required.) Deleted records skipped by a DB_NEXT or DB_PREV operation do not require a separate lock object. Further, if your application is using transactions, no database operation will ever use more than three lock objects at any time.
* For the Hash access method, you only need a single lock object.
For all access methods, you should then add an additional lock object per database for the database's metadata page.
Note that transactions accumulate locks over the transaction lifetime, and the lock objects required by a single transaction is the total lock objects required by all of the database operations in the transaction. However, a database page (or record, in the case of the Queue access method), that is accessed multiple times within a transaction only requires a single lock object for the entire transaction.
The maximum number of locks required by an application cannot be easily estimated. It is possible to calculate a maximum number of locks by multiplying the maximum number of lockers, times the maximum number of lock objects, times two (two for the two possible lock modes for each object, read and write). However, this is a pessimal value, and real applications are unlikely to actually need that many locks. Reviewing the Lock subsystem statistics is the best way to determine this value.
I created DB_CONFIG file, and add three lines:
set_lk_max_locks 20000
set_lk_max_lockers 20000
set_lk_max_objects 20000
As the default values are 1000 of each type of object, my applicaton open 499 database(except internal database) simultaneously(CDB modal) . After changed parameters, my application opend above 6000 database.

HT4059 When I try to load an ePub book it says out of memory. How many books can you read at one time?

When I try to load a second book it says out of memory. How many books can be read at one time?

Thank you so much...
1. I don't have that fat format I checked as I saw this on another answer...BUT...you are right the project was very bloated and I made a new project with the sequence and moved a bunch of projects off to an outside drive and things are flying again...this effect "twirl" was on three clips and this seemed to be creating a problem along with it being a bloated project. Don't know why this effect renders easily then the next second doesn't it's on three clips on the entire project and one or another might not render all of a sudden.
2. I understand what you said about the timeline export...I decided to export the sequence without the matte it was nested in and that sequence did have the chapter markers on the timeline and they again didn't export??? I'll look tomorrow at this it makes no sense if what you're saying is how to do it...the final cut pro book said they should have showed up if I export from the browser and that didn't work either.
3. I then matted that output and rendered it to output but I am worried this will degrade and compress the sequence more than I want by outputting the same sequence with current settings twice???...the couple of outputs I could make nested looked very good as this was one render...however, I tried doing a quicktime "current settings" with the dvd studio pro info still trying to export chapter markers and maybe it's my imagination but the output didn't look as sharp as just an output with just chapter markers???
r. I did look at the final cut pro book and it says that mpeg 2 movies will not read chapter markers anyway if you create one in compressor...if this is true it makes no difference if the quicktime output isn't having chapter markers show up. I assume when I go to author though I can put an mpeg 2 movie into dvd studio pro and create chapter markers at that point!! It seems weird it says it can do it with an mpeg 1 but not an mpeg 2 when everyone is using that for dvds.

MAXLOGMEMBERS: How many people can connect at the same time?

Hello,
how many people can connect at Oracle XE?
When I put 32 to MAXLOGMEMBERS,
oracle xe refuse!
I can put 5 into MAXLOGMEMBERS.
I dont understand
THOMAS Patrice

Hello Thomas,
"MAXLOGMEMBERS" has nothing to do with the number of users that can connect to the instance. It is a parameter to control the number of files that can be assigned to a group of (redo) log files.
how many people can connect at Oracle XE?Well, that depends on how they connect. There are parameters controlling the number of sessions in the database. But if you have a technical user, e.g. when using APEX, there may be more users than sessions in the database...
So you need to clarify what kind of user access you mean.

I am using firefox 3.6.7. with Windows 7. There is no " sort by name" in the dropo down when I right click. How do I alphabatize my book marks?

I want to alphabetize my bookmarks. I am using Firefox 3.6.7 with Windows 7. When I right click on a bookmark no "sort by name" appears in the drop down. How can I do this/

In Firefox 3 the option to sort bookmarks is only available for folders and not for individual bookmarks.
Easiest to sort by name is to do that in the left pane of the Bookmarks Manager (Bookmarks > Organize Bookmarks) or in the sidebar and right-click the folder that you want to sort.

I can't seem to use the 'Check seats' link on Delta when I use Firefox but Safari works fine. I get the message 'not available at this time' when using Firefox but when I go to Safari it works fine.

I can't seem to use the 'Check seats' link on the Delta Airlines site when I use Firefox but Safari works fine. I get the message 'not available at this time' when using Firefox but when I go to Safari it works fine. I love Firefox but this sucks!

That issue can be caused by corrupted cookies.

My browser keeps refreshing, no matter what page i'm on, or how many tabs I have open.

It happens every time I open Firefox. It doesn't matter what site it is, or how many tabs are open. He keeps refreshing all of them.

A few problems could cause this. Try Firefox in safemode, also review what is set as your homepages.
*[[Troubleshoot Firefox issues using Safe Mode]]
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
*[[Startup, home page and download settings]]
*[[How to set the home page]]
Can you give a bit more detail of what happens and
* whether this is just on initial startup ?
* what happens if you close all but one tab ? what happens then ?
* can you describe what you mean by keeps on refreshing

How many sockets can be opened to one port

Hi All,
There is a service installed on port 4444 of our server. In order to do some work with that service we open sockets to it with socket:localhost:4444. The thing we are finding is that it is quiet expensive to initialise these socket connections per request to our website and I'd like to pool connections. I have implemented a pool but currently this closing the connection when returning to the pool. I would actually like them to stayalive in the pool but I do not know if I can have many sockets open to one port?
Thanks!

You are unlikely to get an exact answer.
The first limit you'll probably run into is the number of file descriptors that can be open at a time. This depends on your OS and configured per-process limits.
Socket buffers use memory. Amount of memory, allowed process size (if your OS enforces that with in-kernel buffers), and size of send/receive buffers give another limit.
Other OS-dependent limits, such as a max global file descriptor count, may exist.
TCP/IPv4 (if you use that) connections are defined by a 4-tuple {source address, source port, destination address, destination port}. As long as source address&port are unique, the same destionation address&port can be used. So theoretically you could have some two hundred trillion connections to a port (32 bit addresses * 16 bit ports minus non-allowed addresses.)
In practical terms: check max file descriptor count. A few dozen to a few hundred should be ok for web server -class systems. Try and see what works.

How many photos can I send at a time?

It seems like only one at a time. Some times two?
I tried to send multiple photos by text [5 pictures]
It wouldn't send. No notification or anything. I don't like to send it one at a time. Not cool!!!!!!!!!
Is it just my phone? Can anyone else send multiple pictures? Would love to know.

From what I have understood about the email client , it responds off the email providers size limit when sending email but sending larger files from your device without using wifi may take forever to complete, I have sent out 5-6 mb presentations through my yahoo accounts that originally have a 10 mb limit but it is wiser to use wifi to send files of this size because if signal is weak or lost file can sometime become corrupt but it appears that they still send.

How many macs can backup to a 3tb time capsule?

If I get a 3tb time capsule is there any limit (apart from the drive size) on how many macs can backup to it. At the moment no more than about 20gb of data per mac. Also has the reliability of the time capsule improved with the new version - I would like it to last longer than 18 months.
Thanks
Ben

Let's assume that you backup each Mac separately on the first backup since that will copy the entire contents of the Mac's drive over to the Time Capsule disk. That might average 2-3 hours per Mac.
Once you have the "master" backup of each Mac completed, you can set each of them up for incremental Time Machine backups. On average, the hourly incremental backups only take a few minutes to complete. To be conservative, call it 5 minutes.
So if it takes each Mac about 5 minutes for an average incremental backup, the realistic limit of Macs backing up to a single Time Capsule would be in the 10-12 range. I've had 5 Macs backing up for 3 years with no issues whatsoever.
It would be a good idea to purchase AppleCare for one of your newer Macs if possible. That way, your Time Capsule is covered up to 3 years.
Keep in mind that we tend to only hear about issues on the forums. In that respect, this place is like a hospital...just about everyone here has a problem. No one ever seems to post to report that everything is OK.
You don't hear about the millions of devices that are working just fine, so it's tough to make a judgement on a product based on what you see and read here.
