Firefox opens mobile pages on desktop

Certain sites (such as www.gamespot.com.au, and Facebook depending on how you get there) open in their mobile versions. It's been doing this for a while, and is extremely annoying.
I'm on Firefox 13.01 at the moment, but like I said, it's been going on for a while.

Looking at the system information aside your user agent string is showing as
* ''PLAYSTATION 3; 1.00''
Are you using Firefox from playstation PS3 ?
You may get a better answer on a playstation forum, or you may be lucky and get a reply here. I had heard Playstations could use IE but I was not aware they could use Firefox, unless they are hacked.
I would make a guess that changing the User Agent String may solve the problem.
With ordinary Firefox installs on a Desktop Computer the the user agent string may be changed manually, or by using add-ons, but I do not know about PS3 installs.
No idea if any of this may help

Im having a problem with Firefox opening web pages that i have set as my home page such as Google also will not open Yahoo but will open most bookmarked pages

After starting Firefox the Firefox homepage comes up with the google search, but if i enter anything in the search bar, nothing happens it just says done. Also my homepage is Google, imported from Internet Explorer, but doesn't come up when i start Firefox, And Also at the top on the tab it just says untitled. Now with that being said if i enter in yahoo or yahoo.com in the search tab or even enter in the actual web address, it still doesn't open it just says done at the bottom of the page and nothing happens, But if i go to the Bookmarks also imported from Internet Explorer it will open or display most all of the web pages it just seems to be having problems with search engines such as Google, and Yahoo. Now if i enter Ask.com in the web address search tab it will open that page but if i enter Google.com or Yahoo.com nothing. Also like i said most all bookmarks will open but yahoo or my yahoo that is saved in Bookmarks will not. and nothing happens with any entry made into the Google search displayed on the the Firefox Start Page.

Hi,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" 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.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Dreamweaver pages won't preview in Firefox since last update (3.6.13); Firefox opens blank page only. I am running OS 10.4.11 on iMac G5.

Previously both Firefox and Safari would display web pages created in Dreamweaver (MX). Dreamweaver is set up to preview by default in Safari (F12) and, using (F12) and the Command modifier key, in Firefox. Now the preview works only in Safari. Trying to preview in Firefox results in Firefox opening, if it wasn't already running, but only a blank page displays.

That didn't work. The problem is now on both accounts
That's an indication the startup disk may need repairing.
Launch Disk Utility. That's located in /Applications/Utilities
Select MacintoshHD in the panel on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If the disk needs repariing follow the instructions for Using Disk Utility to verify or repair disks

Firefox opens every page five times

Whenever I click on a link to open a new page, Firefox opens it five times (in the same tab). So when I want to go back using the back and forward arrows, I have to click them five times to get back to my previous page. This is a new problem, since about 2 days...
== This happened ==
Every time Firefox opened
== I guess since the last Firefox update

Do you have any extensions installed? Try [[Troubleshooting extensions and themes]].
Also, please update Flash: http://get.adobe.com/flashplayer/
The version you have is outdated and has security and stability problems.

Unterminated string literal error every time firefox opens a page.

Every time firefox opens a new page, the error pops up. It says Javascript error at the top of the error window - and the error is "unterminated string literal. It very annoying, some pages have multiple instances of the error window popping up on top of each other. I reloaded the program, no changes. I am ready to give up and go to Chrome (which does not have the error)

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

Firefox opens web pages but not all the data or pictures.

Firefox 22.0 opens web pages slowly, it takes up to 30 seconds to load and then not all the pictures and data is loaded or it times out. If I hit the reload button, everything loads OK. This happens on mant sites, not just a few.
I use Google Chrome as my primary browser, and it is quite fast. My internet connection is commercial and it is OMG fast. I would like to replace Google Chrome( I hate being tracked), but at this point, the Firefox is just too slow.
Please advise how to correct these issues.
Thanks

Which security software (firewall, anti-virus) do you have?
Make sure that Firefox is fully trusted in your security software.
You can check for problems with preferences and rename or delete the prefs.js file and possible numbered prefs-##.js files and a possible user.js file to reset all prefs to the default value.

My browsing sessions are being hijacked as Firefox opens some pages. Started when updated to v20.

Open pages spontaneously change to random advertising sites. happens a lot to yahoo home page. does not appear to happen in IE10 or chrome. also there is a pop-up box showing up at the bottom of some pages asking if I want to go to some ad on the page.

Sounds suspicious. You may want to run some supplemental security scans. These two tools are highly regarded:
Malwarebytes Anti-malware : http://www.malwarebytes.org/products/malwarebytes_free
SUPERAntiSpyware : http://www.superantispyware.com/
Meanwhile, within Firefox, disable ALL newer, nonessential, and unrecognized extensions here:
orange Firefox button (or Tools menu) > Add-ons > Extensions category
Any change?

Firefox opens last page when set to load another

In the settings i have "Show my home page" set to google.com when it starts.
But if i close a window and restart firefox it just opens the previous page i was viewing.

Is there a user.js file in the Firefox profile folder?
You can use this button to go to the Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
Note that Windows hides some file extensions by default. 
Among them are .html and .ini and .js and .txt, so you may see a name without file extension, i.e. user and not user.js. 
You can see the real file type if you open the Properties via the right-click context menu

How do I configure Firefox to open multiple pages on startup and not set my homepage to open mutliple tabs?

So I know how to set my homepage to open multiple tabs, however it has the undesired effect of making it so those tabs are opened every time I hit the homepage button. Is there a way to set Firefox to open multiple pages on start-up, while not actually setting the homepage to open multiple tabs?

You can edit a copy of the Firefox desktop shortcut and add the links to the target field to make Firefox open those pages when you use this shortcut.
See:
*https://developer.mozilla.org/Command_Line_Options
If you run out of space (i.e. exceed the maximum length) then use a CMD file with the start command.
*start "" "<path_to_firefox\firefox.exe>" URL1 URL2

Okay, that's a lot of information. I think the key part for support purposes is this:
''TheDrive [[#question-1057777|said]]''
<blockquote>
Just try yourself. Setup new profile and work a few days or weeks on any theme(s). Do not close tabs (at least ones, which you wanna explore once more). If your PC has 2-4Gb of RAM you will notice FF stopped to save session info after you will have a 50-100 tabs opened (you'll see sessionstore.js or session-backups\*.js script files reached 15-20-30MB long and stopped to change and it's LastMod date/time(s) are frozen) ... 
... I've noticed FF started to hang more and more and checked previous.js, recovery.bak, recovery.js was last modified on Apr, 14 but today is Apr, 16! I've lost one more hour trying to save tabs, even installed Session Manager, promised session saving on user demand but after a half hour of action against hanging FF, plugin showed me that I have NO ONE tab to save. I've managed to copy a few URLs to the text file before FF have completely fallen.</blockquote>
You're not the first person to report that the sessionstore.js or recovery.js file stopped updating with new activity. However, it's rare enough that I can't recall whether we have gotten to the bottom of it in a previous thread. I'll see whether I can search it up.
Meanwhile, someone might be able to come up with a way to watch for problems and extract some debug information, but I'm not personally familiar with such tools.

When I try to open Firefox by clicking on the desktop icon, all I get is a Bing search page and no Firefox.

When I click on the Firefox desktop icon, I get a Bing search page. Nothing relating to Firefox is evident and the only way I can get out of the Bing search page is using Control/Alt/Delete. I can't access anything in Firefox at all.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

If there is a problem with searching via the default about:home page then try to reset the search engine used on the about:home page.
Reset the browser.startup.homepage_override.mstone pref via the right-click context menu to the default on the about:config page and close and restart Firefox to restore the about:home page to its default.
*http://kb.mozillazine.org/about:config
#Open the about:config page via the location bar
#Type in the Filter bar: mstone
#Right-click the browser.startup.homepage_override.mstone line and select: Reset
#Close and restart Firefox
If this didn't help then delete the delete the chromeappsstore.sqlite file in the Firefox Profile Folder and repeat the above.
You can reset some preferences to the default with the SearchReset extension:
*https://addons.mozilla.org/firefox/addon/searchreset/
Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).

My bookmarks only show up on the mobile Firefox, but not in the desktop browser. How can I fix it?

This is how it all happened:
1. Bookmarks first disappeared on one of my desktop computers.
2. Bookmarks disappeared on another desktop computer. Additionally I was unable to bookmark any new page - after I press the star button it would be blank (not yellow).
3. I can see my bookmarks on my tablet with updated Firefox Beta. But I am worried they will disappear soon too.
4. When I checked the Sync Quota it shows that Bookmarks only use few kilobytes even thought I have hundreds if not thousands of bookmarks.
5. I have reinstalled the browser removing all personal data, but the only thing that changed is - I now can add bookmarks, although not through Right Click->Bookmark This Link.
I strongly believe this is a bug in the Sync system and am now considering switching to chrome

'''Did you backup whatever bookmarks you did have on the computer ? '''
Remember any restoring of bookmarks overwrites whatever he current set is, and you may not want to loose them.
Even if up until now you have not made any backups of Desktop bookmarks Firefox will have backed up some of them into sets of daily bookmark backups. Once you have backed up your current set you could look at what it has by restoring those bookmarks, you may find one of those sets is fairly complete.
By the way if you look at the profile files and folders that you should now have on the desktop you should see it contains a bookmarks backup folder, the size of the files within should indicate whether they contain anything.
You need to go into the bookmarks library and try the restore option. Backup each set that you look at if it has anything of use in it, before trying the next set. With look one of those will be a fairly complete set of bookmarks.
* USE '''Show All Bookmarks -> Import and Backup -> Restore '''
** see [[Restore bookmarks from backup or move them to another computer#w_restoring-from-backups]]_restoring-from-backups
I do not use Firefox on mobiles, but before you try anything further you do need to backup the desktop bookmarks and learn what existing backups you have. Unless you master that you are in continual danger of overwriting and loosing bookmarks.
Presumably you have already found this listing of help articles for mobiles
