Since upgrade Firefox opens in wrong monitor window.

Since upgrading yesterday, Firefox ALWAYS opens on Monitor 1 instead of Monitor 2. I have DELETED all add-ons and plug-ins. I have minimized, maximized, moved from Monitor 1 to Monitor 2 without maximizing or minimizing, and Firefox ALWAYS opens in Monitor 2. I'm running Mac OSX Lion. There were no issues until the Firefox upgrade yesterday. GRRRRR!

unfortunately this is a regression in firefox 12 on mac os x that has been reported here in the forums quite few times. there are already some bugs filed for the issue & hopefully it will be resolved in one of the upcoming releases (although judging from the bugs' stati there isn't much progress yet).

I am running Snow Leopard 10.6.7 Firefox opens on wrong monitor.

I have two monitors with my Imac. My primary monitor is where Safari opens and Firefox used to. I just installed Snow Leopard 10.6.7 on my Mac. I just upgraded Firefox. My primary monitor is my left monitor. I have opened Firefox. It opened on the right monitor. I dragged it to the left monitor and resized it. Upon the next relaunch, Firefox opens on the right monitor.

Before doing any installation restart OSX from your 10.6 Snow Leopard DVD and use Disk Utility to Both Repair The Disk and Repair the Permissions of your Macintosh HD.
Next remove your Snow Leopard DVD and restart your iMac into OSX.
Update to the latest version of OS X Snow Leopard by clicking the Apple icon and choose Software Update to install Snow Leopard v10.6.8, the latest version.
Use Time Machine to make a Full Backup of your Macintosh HD.
Shut down and restart into Windows by holding the Option key at the chime and selecting Windows.
Now use Windows Backup to make a Full Image Backup of your Windows Installation to a removable drive.
Shut Down and Boot back into OSX.
Open the Mac App Store from your Dock to buy and download Mountain Lion. Then follow the onscreen instructions to install it.
Upgrading your OSX to 10.8 should not effect the Windows Partition at all since you are only upgrading the Mac side. You should not have to run the Boot Camp Assitant 5 Utility in OSX at all.
Your Boot Camp 3.3 Windows Support Drivers et. al only effect your Windows installation and should continue to run fine after upgrading.
Which version of Windows do you already have installed on the existing Boot Camp Partition?
Is it 32 bit or 64 bit?

Since upgrading Firefox, it no longer accepts URLs in the URL bar - it works if I have a bookmark, a link or from History, but not if I enter or paste a URL.

Firefox 33.0.2 on Windows 8.1 64 bit. Since upgrading Firefox, it no longer accepts URLs in the URL bar - it works if I have a bookmark, a link or from History, but not if I enter or paste a URL and hit <enter>, in which case nothing happens at all.
I have found that issue reported for Ubuntu (https://support.mozilla.org/en-US/questions/1011935?esab=a&as=aaq) but not for Windows. The solution there to change the keyboard is not feasible since it's a laptop with a built-in keyboard.
I did not have this issue with FF 28 (I finally upgraded because I was getting BSODs) and I don't have this issue with any other Browser on same platform.
Any help appreciated.
Thanks.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode". 
[[Image:Safe Mode Fx 15 - Win]]
'''''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 [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit 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 others with the same problem.

Firefox opens up an explorer window when I download a file

Recently, Firefox started opening up an Explorer window every time I download a file. It's Better Explorer, actually, since I use that to replace the Microsoft version. The folder that opens is the target destination. So it creates multiple tabs, but I expect that it would just open up multiple instances of Windows Explorer if that's what I used.
So if I download a dozen images, I get a dozen tabs opened. This doesn't happen with IE or Chrome. I do have multiple extensions installed, but I've gone through the options in Firefox and any relating to downloads and none of them seem to have anything that might cause this. I did check the Applications tab under the Firefox Options, since that seemed like a probable cause. But I don't see anything. And I don't recall changing anything recently, in any case. I can't see anything in Better Explorer that would cause this behavior. Which is borne out by this not occurring in other browsers. And I haven't changed anything it, either.
I tried downloading something with NetVideoHunter and I get the same behavior. But it doesn't happen with DownloadThemAll!
I've tried researching it on-line, but the queries I use are apparently too similar to the ones for other issues, because nothing that comes up is even close to my problem.
As this is getting very annoying, any help would be greatly appreciated. Firefox remains my favorite desktop browser and I'm not prepared to give it up over this. But I'd hate to have to reinstall it, since I have it configure just the way I want it. And I'm not even sure that would fix the issue.
Thanks

Start Firefox in [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode safe mode] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Do NOT click the Reset button on the Safe Mode start window.
* https://support.mozilla.org/kb/Safe+Mode
* https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
In Firefox Safe mode these changes are effective:
* all extensions are disabled (about:addons)
* default theme is used (no persona)
* userChrome.css and userContent.css are ignored (chrome folder)
* default toolbar layout is used (file: localstore-safe.rdf)
* Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
* hardware acceleration is disabled (Options > Advanced > General)
* plugins are not affected
* preferences are not affected
Your profile folder contains a user.js file, which includes preferences that were not created by Firefox.
so you may want to also check for a user.js file and DELETE that.

Firefox opening tabs in new window

Whenever I "open in new tab" Firefox will open said tab in a new window instead of the current one. If I repeat this four times with the same link in one window, I will have four tabs in one new, separate window. I'd rather have those four tabs in the original window.
I do have the "open new windows in a new tab instead" option selected.
Probably just a setting I have flipped to the wrong position, but any help would be appreciated.

This could be due to the way Firefox 4 handles windows popped up by a script in a web page. In some cases, Firefox judges the window to be a "dialog" and diverts all new tabs to a different window.
When you encounter this can you do the following test: Copy the URL of the "problem" window, open a new normal window (e.g., Ctrl+n), paste the URL into the location bar, and press Enter. Then try right-click > Open Link in New Tab in that window. Does it work normally there?
If so, it's the dialog problem. This thread has more information: [https://support.mozilla.com/en-US/questions/813647 How to allow tabs in dialog boxes again? | Firefox Support Forum | Firefox Help].
If not, it must be something else.

Flash plugin will not install since upgrading Firefox

Since upgrading to the latest version of Firefox, my Flash plug-in no longer works and after repeated attempts to download and install (both the manual Flash installer, and by visiting pages like Youtube which prompt installation) nothing is working. It's a frustrating loop that gets me nowhere and I've spent hours now uninstalling Flash, uninstalling Firefox, reading through forums etc. and I am getting no help aside from some suggestions to just give up and use Chrome, which is working with Flash just as well as it ever did. I can't understand why it seems like many people are facing this issue, yet there is no apparent fix to be found.

1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

How to stop the email in mozilla firefox opening in a new window( I want it to open in a new tab)

in the toolbar when I press the email button, my email opens in a new window, when I want my mail to open in a new tab. Please can you help????

I don't think Firefox has a built-in email button. Do you have an add-on that created that button, or do you mean a button pinned to the Windows Taskbar?
If it's an add-on, check whether it has an settings available for window vs. tab. If this doesn't appear with the button itself (for example, using a drop-down triangle next to the button) you can check the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then check the list for the relevant extension and try its Options... button.

Why does Firefox open in a new window with some sites? I hate this.

In some instances, a new browser opens with my homepage when typing in certain websites. I didn't have this problem before upgrading to 7. I hate this.

That are probably JavaScript window.open() calls that specify window dimensions.
You can divert those to a new tab.

Firefox opens in a tiny window and I want it to open full page..How?

Firefox opens at my home page as desired, but it is on a window in the upper right corner, about 4"wide and 3" tall. It readily drags out into a full-sized display, but I want it to open that way, as it did before I updated to yesterday's version of Firefox. i find no options immediately obvious to set this opening size as a default. How do I do this? Also, I now have a problem with Flash crashing that I did not have before the update. How do I fix that?

I see that you have some crash reports that are about the Shockwave Flash plugin:

Firefox opens in a small window in top left of screen

Whenever I open firefox it opens in the top left portion of the screen with the close minimize and maximize buttons only, the maximize button is shaded the curser is in the waiting form the whole time.
== This happened ==
Every time Firefox opened
== Downloaded latest version of firefox ==
== User Agent ==
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.86 Safari/533.4

Opening in the Sidebar is the default action for bookmarks that are created via a "Bookmark this Page" link or button on a website. Make sure you use the many "Bookmark this Page" methods that are in Firefox instead.
Right-click that bookmark and select '''Properties''', then un-check the preference for '''Load this bookmark in the sidebar''', and then click Save.

... in Roundcube email list since upgrading firefox for long entries

Islandnet.com uses Roundcube for its webmail client and up until the most recent Firefox update if a subject line for example was too long for the subject column it would display as much of the subject as it could in the space provided.
Since the firefox updates it now substitutes ... for long subjects.
I am going to submit the same request to roundcube development as they may be able to make a change on Roundcube to resolve it but its only since more recent Firefox updates that this has occured, Seemed to be fine of 3.6.x yersions.

Hi papapinous ,
You should take a look at [https://support.mozilla.org/en-US/kb/latest-firefox-issues this article] that discusses some of the issues with the latest build of Firefox.
There is some information in there that should help you to resolve your issue. Luckily, it is a very easy fix.
Hopefully this helps!

Since upgrade FireFox no longer opens with last session, how do you this version 4?

Previously when using Firefox 3.6 I could have multiple tabs open and when I closed the browser, the next time I opened Firefox it would reopen the same tabs.

Tools or Firefox > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

Since upgrading firefox my tiscali (through Talk talk) email account will not allow me access to my emails saying 'You have undefined new mails in your inbox' and will not open the page. it works on Internet Explorer.

It thinks there is no information there! If I revert to 3.6 how long will security be maintained. At the moment I am opening Mozilla for web browsing but IE for my email account. I am not very PC literate so need simple answers.

Apparently TalkTalk mail will work with Firefox 4 and Firefox 5 ''if'' you set the browser to ''lie'' to TalkTalk mail by saying that you are still using version 3.6.
You can find the instructions for that in a post on the TalkTalk forums: [http://www.talktalk.co.uk/forums/showthread.php?t=185113#post2452787 Firefox 4 & TalkTalk webmail - Forums].
Note: when you open about:config the first time, it will display a warning message that you should be careful with the changes you make. That's definitely good to bear in mind.
Does it work?

Since upgrade Firefox opens in wrong monitor window.
