Firefox 6 hangs opening multiple tabs simultaneously

After updating from Firefox 5 to 6, opening more than 6 (or sometimes 8) separate website pages in tabs (via "Open All in Tabs") simultaneously hangs Firefox networking. After this, no page reloads (or plugins) can access anything remotely (constant reloading and eventual connection lost).
Closing and restarting Firefox allows connection again.
If the same sites are loaded in smaller groups of 4 or 5 at a time, there's no problem. Once the sites have been loaded manually, reloading them in larger groups works until Firefox is restarted and the problem recurs.
I have tried this on a clean install as well as an upgrade. I have disabled all extensions/plugins, made sure a proxy is not being used, disabled IPv6 and DNS caching.

I've been having the problem with as few as two tabs opening. The only time it does not do it is in safe mode. I have cleared my history, turned on the plugins one at a time, and run virus check. With any plugins turned on, it hangs every couple of web pages opened.

Since upgrade to 22, Firefox hangs opening multiple tabs.

Since upgrading to 22, Firefox hangs or does not respond when loading new tabs and when trying to open toolbar items. This happened IMMEDIATELY after upgrading. Here are all the Windows 7 forced closure reports:

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. 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 Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Can I open multiple tabs in Firefox when WINDOWS starts up? Command line limits to about 204 characters...

I know how to configure Firefox so that it opens multiple tabs every time you open ''Firefox''. I want it to open multiple tabs when I start ''Windows''. Or in other words, I don't want to connect to multiple web pages every time I open a browser, just the first time I log on for the day.
I tried appending the web sites in the command line of a Firefox shortcut in my Windows Startup folder. The problem is that in this approach, you're limited to as many URL's as you can type in about 204 characters ('C:\Program Files (x86)\Mozilla Firefox\firefox.exe' uses up 52 of the 256 characters available in a shortcut).
Is there a way to open more tabbed web sites than that?
What would be cool is if there was something like a FFstartup.ini file or something, where you could provide a list of websites as long as you want, and it would open them all. So, the command line would look like:
'C:\Program Files (x86)\Mozilla Firefox\firefox.exe' 'C:\Program Files (x86)\Mozilla Firefox\FFstartup.ini'
...and the FFstartup.ini file would look like:
[Startup]
'http://www.yahoo.com'
'http://www.google.com'
'http://www.firefox.com'
etc...
If there's no current way to do this, how would I make this suggestion to be developed?
Thank you!

Use a .bat or .cmd file to start Firefox if you need more space than the target line in a shortcut allows.<br />
Separate the URLs with spaces.

Firefox on my laptop will not allow me to open multiple tabs, how can I fix this issue?

I usually use firefox and yesterday was downloading a photoshop program called gimp. all of a sudden after downloading it, firefox stops allowing me to open multiple tabs. I click on file and new tab, but it still will not work.

The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
There are a couple of places to check for the Ask toolbar:
* Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
* Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

Firefox will not open multiple windows.

Just upgraded to Firefox 3.6.3. I can open multiple tabs in the open window, but I can not open another window. Possibly unrelated issue is the search bar not functioning.
As for the window issue, I've tried;
Ctrl + N
File [N]
File -> New Window
Rt Click Link -> Open in New Window
Nothing whatsoever happens with either of these attempts.
As for the Search bar I've tried to input a search and press [Enter] as well as clicking the magnifying glass with the mouse. As with the window issue nothing happens.
I'm not sure if these issues are related. Restarting does not fix these.
Addons are:
Adblock Plus v1.2
Add to Search Bar v2.0
All-in-One Sidebar v0.7.11
Bookmark This Page Plus v0.3.3
ChatZilla v0.9.86

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.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

How can I actually open multiple tabs of the same site, instead of performing the new "switch to tab" action?

For example, sometimes I would like to open multiple tabs of Google Maps to get directions to multiple locations, and I haven't found a way to do so without open a new instance of the browser. Thanks.

This one colors tabs, but the author warns that it doesn't work with other tab-related extensions, so you probably need to keep searching for one that does everything you want:
https://addons.mozilla.org/en-US/firefox/addon/colorfultabs/
If you don't find a do-it-all extension, you can modify the tab titles with a userscript that is specific to that website. This is because the tab displays the text designated in the page as its title.
You either could "hard code" the list of words for each of the pages, or you could have a script extract information from the page, for example, the first main heading, or some other predictable bit of data. The script then would insert your preferred wording as the title of the page and Firefox will show that on the tab.
To see how that appears, so you know whether it would be useful, you could do this experiment:
On a web page that has useless tab text, open the Web Console using command+alt+k (Windows: Ctrl+Shift+k). In the line at the bottom next to the caret, paste the following code and press Enter:
document.title="Magic!";
If you decide you want a script written for this, you could try the request forum on userscripts''.''org:
[http://userscripts.org/forums/2 Ideas and script requests - Userscripts.org]
Although some people offer small payments, that usually isn't necessary to motivate people to help.
Let me give you a brief warning about that site, though: over the past year, a lot of popular scripts were duplicated and reposted with additional code that hijacks your Facebook account. Be cautious when installing scripts, check the reviews, make sure there are no references to Facebook.

Latest Firefox will not allow multiple tabs on my Mac !!?!!

I have the most current version of Firefox and since it loaded, I can no longer open multiple tabs either by clicking on the + or by selecting New Tab from the file menu. My only option seems to be to open another window - I would rather have multiple tabs. What happened to the new version?

Hello,
We're sorry to hear that you have a problem.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. <br>
'''Note''': ''This will cause you to lose any Extensions and some Preferences.''
*Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
'''For Firefox versions previous to 29.0:'''
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox"[[Image:Button reset]] button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
'''For Firefox 29.0 and above:'''
#Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''.
Now, a new tab containing your troubleshooting information should open.
#At the top right corner of the page, you should see a button that says "Reset Firefox"[[Image:Button reset]]. Click on it.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.

Why when I open multiple tabs in Facebook, the tabs load very slowly and most times don't load at all?

Why when I open multiple tabs in Facebook, the tabs load very slowly and most times don't load at all?

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
You can try to decrease the value of the pref <b>network.http.max-connections</b> from 255 to a more modest setting like 30 as used in Firefox 3 versions.

Adobe Acrobat pro 9.4.6 crashes when opening multiple files simultaneously.

We have Adobe Acrobat Pro 9 which has been updated to version 9.4.6. we had this problem when the 9.4.5 update was applied also. It is now crashing when we try to open multiple files simultaneously.
Yesterday, I narrowed down the problem to 6 plugins:
IA32
ADBC
eBook
EScript
HLS
PPKLite
SaveAsRTS
However, we discovered that that Comments and markup tool bars weren't loading. So I did a repair install on it.
Now those plugins from yesterday work and Acroform.api is causing it to crash when opening multiple files.
I did try other suggestion that involved using Icacls/cacls on dll files to no avail.
It is running on XP SP3 fully updated with plenty of RAM and HDD space.
Is there a way to fix this without reinstalling?

I am not sure what's causing this problem on your machine because everything's working fine for me.
What is the version of Acroform.api on your machine now.
Do a Repair after deleting this file and see if it works.
Enable Windows MSI logging (http://support.microsoft.com/kb/314852) before you do a repair, upload that log to some file sharing server, and paste its link here.

HT4623 Opening multiple tabs within Internet Safari on my iPad mini

How am I able to open multiple tabs within Internet Safari on my iPad mini?? I have an iPhone and I can do so but on my iPad mini I can't figure it out or it just doesn't have that option. Someone please help with some answers, thank you!!

Thanks for your response, that's exactly what I thought the + sign was for but I've tried that and when I do it completely closes out safari. I did some other research and it seems to be happening to others also. So not sure what to do now or how I can get multiple tabs opened just like you can on the iPhones.

Firefox will not open new 'tabs', not sure if its disabled, but does anyone know how to enable the use of my tabs?

Firefox will not open any tabs on my browser. I've tried using all alternatives to open a new tab - using the 'plus' (+) button doesn't work, 'control + T' doesn't work, going to File and clicking 'new tab' doesn't work either? Help please!

Your suggestion worked! Thanks!

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser. Anyone know how to fix this?

Since updating last time Firefox will not open new tabs unless I right click on a link. It won't open them via file or the tab at the top of the brwoser or usinf ctrl + t. Anyone know how to fix this?

I can press ctrl for a new tab but otherwise a new tab does not open. I actually need help regarding this new Synch which apparently will be in Firefox automatically in an upcoming version so I am asking how that will synch with people who use LastPass-of course because I use this very successfully and really am not eager to change the set up that I have in place at this time.
I have read through endless FAQ trying to find anyone else who has this question or concern but have found nothing. Can you please tell me how that service will get along with LastPass which does basically the same thing as Synch-it is probably spelled wrong as it looks wrong to me but if I click back to where this issue began, I will lose all of this question so please respond for the upcoming service synch.
