Why is Firefox 29 is laggy for me?

Hi, since I updated to FF 29, my browser has gotten unbearably laggy/choppy. If I type, letters appear slower than I hit the keys, and if I move my mouse over a link it takes a second or two before the link overlay effect (underline, highlight etc) appears, same goes for all buttons, tabs, menus etc. If I enable hardware acceleration, the choppyness goes away, but I get a different problem in exchange. With hardware acceleration on, the text and sometimes images on my screen occasionally get really blurry. This does not happen with hardware acceleration off. How can I fix these or atleast one of these issues so I can comfortably use Firefox again?

I found that after Firefox v29, a LOT of my settings and 
add-ons were changed / reset. Try this;
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
 While you are in safe mode; 
'''''Firefox Options > Advanced > General'''''. 
Look for and turn off '''Use Hardware Acceleration'''. 
Then check ALL of your settings. Browser and add-ons. Then restart.

Why does firefox drop support for a plugin with an update

Why the H*ll does Firefox drop support for a plugin when there is an update in Firefox.
FF4 has reported that 6 of my plugins that work fine in 3.6 are now not supported. !! This is a joke, and happens regularly.
As a user (a highly IT literate one) this is annoying and frustrating, and from a design standpoint, unprofessional.

Plugins as in Flash, Java, quicktime or such or do you mean Extensions ?
Plenty of Plugins seems to be detected and in use by Firefox 4.0 just fine according to your system details by your post.
If you meant Extensions then check for updates, look at addons.mozilla.org or the Extension homepage for to see if the author has provided a update.
Generally Extensions can need anywhere from a simple maxversion bump to a lot more for it to work properly on a new Major version of Firefox depending on what the Extension does.
It is professional actually as extensions that were not actually compatible may actually cause problems big or small if they were to still just ''work'' in a new Major version release so hence the need for them to be properly up to date on any changes and hopefully the extension author is quick about it.

Why does Firefox now ask for my master password every time I check my gmail account? Sometimes, but not always, for my Yahoo mail account. Never did this before. Thank you.

Don't know how to add any more details.

Why does firefox keep asking for permission every time it starts, it never has before?

I'm using Windows 7 and recently used CCleaner to clean my registry and now Firefox asks for permission to make changes to my computer every time it starts. I have checked for viruses and malware, tried running Firefox as the administrator, removed all but one of my add-ons but nothing helps. Any suggestions?

Check that you do not run Firefox as Administrator. 
Right-click the Firefox desktop shortcut and choose "Properties". 
In the Compatibility tab, make sure that Privilege Level: "Run this program as Administrator" is not selected. 
You also need to check the Properties of the firefox.exe program in the Firefox program directory. 
If you can't make the changes then you need to start Windows Explorer as Administrator.

Why does Firefox show euro for every currency even if I want to see info in dollars/yen, etc?

When I browse a site with prices - eg a travel site , the browser always shows the euro symbol rather than the dollar symbol or whatever currency it should be! Is there a fix for this?

hello,
can you advise me how i can use a euro symbol in a query? and is it possible to switch currency symbols back and forth?
i do not have a proxy extension installed.
using firefox 3.6.17, windows 7 pro
thanks!

Why is firefox not available for android devices that are not phones, since android market insists on a mobile phone number; isn't Mozilla afraid to lose fans ?

I own a Coby Kyros MID7024; it has android 2.2. However it is not a mobile phone, therefore it's impossible to download anything from the Android Market; it provides Appslib by default, and firefox is not available there (yet ?).

Coby Kyros tablets do not ship with Google Mobile applications such as the Google Market or Gmail. It does not need to be a phone to have Google Market.
You can install it manually. http://releases.mozilla.org/pub/mozilla.org/mobile/releases/7.0.1/android/en-US/
It has essentially a Cortex-A8 (ARMv7 and 512MB RAM so it should work.

Why does Firefox ask me always for permission to use some obscure fonts?

Why does Firefox always ask for permission to use some obscure fonts?
== This happened ==
Every time Firefox opened
== A few weeks ago

Yeah the whole "blame the OS" thing is a red herring. What the hell is Firefox doing looking on my external drives in the first place? It asks permission to use a font on another drive, but what else is it looking at outside of the Applications folder where it should know enough to mind its own business?

Why does Firefox hang when accessing SSL content on Oracle 10.3.6 WebLogic with JSSE enabled?

For several weeks we have been working with Oracle support to find out why our Firefox browser hangs for 20-30 seconds when connecting to SSL content on 10.3.6 WebLogic only when JSSE is enabled. It occurs when first attempting to connect to an enterprise WebLogic deployment. When JSSE is disabled the problem does not occur but JSSE must be enabled on WebLogic for our configuration. The problem also does 'not' occur when JSSE is enabled when using IE (8). In 10.3.5 WebLogic, the issue does not occur with Firefox but 10.3.6 is our preferred version and this is a major issue for us.
For the Firefox version, we used version 18 and 17 with no difference. Thanks for your help.

When i want to go another from a tab,it shows firefox not responding, for a while then opens that tab!this is embarrassing me a lot by taking so much time!!why

I have two inconviniences with fire fox..
1)when i want to go another from a tab,it shows firefox not responding, for a while then opens that tab!this is embarrassing me a lot by taking so much time!!why it happens?
2) every time when adobe flash player is updated, it shows flash player can't be installed and it crashes! it says 'disable real player' though i never installed real player!!
plz Let me know why it happens to me????

1. Update firefox to the latest version 2. and disable real player in menu->addons->plugins.
Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox 13 are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
[[Flash Plugin - Keep it up to date and troubleshoot problems]]
[[Flash 11.3 crashes]]
[[Flash 11.3 doesn't load video in Firefox]]

http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
Please tell us if this helped!
Please check if all your plugins are up-to-date. To do this, go to the [http://mozilla.com/plugincheck Mozilla Plugin Check site].
Once you're there, the site will check if all your plugins have the latest versions.
If you see plugins in the list that have a yellow ''Update'' button or a red ''Update now'' button, please update these immediately.
To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Why does Firefox 31 change all PDF icons and opening in browser, require a fix using REGEDIT to fix for ALL USERS on a computer?

The solution to use REGEDIT in the question linked below almost fixed my trouble with PDF files on over 30 computers, with several users on each computer:
https://support.mozilla.org/en-US/questions/1013642
But I needed to fix it for ALL users on a computer, without logging onto each account, on each computer. My fix was to logon as administrator and change the following system-global key instead:
HKEY_LOCAL_MACHINE\Software\Classes\.pdf
Name: Default
Type: Reg_SZ
Data: FirefoxHtm
Changed the data from FirefoxHtm to AcroExch.Document.11
I use Adobe Reader XI on Win7 Pro, 64-bit machines.
The problem started when I ran a downloaded file to install the new version of Firefox on the computers.
Why would Firefox require me to use REGEDIT in this manner to fix the problem?

This only happens when you set Firefox as the default browser and Firefox thinks that there is currently no application the handles PDF files.

I keep getting "Unable to connect" for my firefox. It was working yesterday and I turned my computer off. I can get to the web using internet explorer 9. I don't know why my firefox is not working. Everything else is working. HELP....

I keep getting "Unable to connect" for my firefox. It was working yesterday and I turned my computer off. I can get to the web using internet explorer 9. I don't know why my firefox is not working. Everything else is working.

A possible cause is security software (firewall) 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 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.

Why does Firefox for android spring open when I clear notifications or open files?

Motorola Moto G
Latest Firefox for android
Android KitKat
Why does Firefox spring open, even after I quit, because I have cleared notifications or opened a file I downloaded. I have double checked Firefox is NOT set to open images or videos automatically, es

ES File Manager is my default player for almost all media. Firefox is not set to default.
Here is a step by step.
I see a picture I like so I download it. Firefox has now sent me a notification that the download is complete. After eventually closing the browser, I then clear notifications. Upon doing so, Firefox opens, regardless of whether it was running in the background or truly closed.
Thanks

Adobe Acrobat Plugin in Firefox 29.0 for Windows 8.0 does not print documents. Why?

I opened a document in Adobe Acrobat plugin version 11.0.6.70 in Firefox 29.0 for Windows 8.0 and attempted to print the document, but all I got was a blank sheet of paper. So I saved the Adobe document to my hard drive. I then opened that Adobe document in Adobe outside of Firefox. Adobe printed that document just fine. Firefox was just updated to version 29.0 a day or two ago. Prior to that I did not have any problems printing Adobe documents from within Firefox. Why did the Adobe 11.0.6.70 plugin not print the document from within Firefox 29.0?

hello, you might not actoally print with the acrobat plugin but with the built-in firefox pdf viewer which unfortunately currently has this blank page printing bug - this is investigated by our developers. in the meantime you could use a third-party pdf plugin that you can enable in the firefox ''options > applications'' - scroll down and define the default action for the '''portable document format (pdf)'''.

Why is Firefox button not default for Windows XP?

I know that the Firefox button can be shown on Windows XP too by hiding the Menu Bar. But why is it not default? If Windows XP users do not know that Firefox button can be shown by hiding Menu Bar, they will not only not be able to access the Firefox button but will also not be able to enjoy tabs-on-titlebar. Describe Mozilla why it is not default???

One thing to keep in mind about Chrome is that Google started with a clean sheet of paper in ''(what?)'' 2008 when creating a new browser. Firefox has roots from Netscape in 1995, so some of the Gecko base code is pretty old. Plus, Google has a helluva lot more money to spend on developer ''(some of whom have been hired away from Mozilla)'' salaries, where many Mozilla developers are from the "community" and are unpaid volunteers.
I am running the nightly Minefield 4.0b13pre development version on WinXP and don't see tabs in the titlebar as with the Vista and Win7 version screenshots I have seen. With a "stock" Profile, when I hide the Menu bar and select the menu item for Tabs on Top, the only thing in the Titlebar is the Firefox button on the left side of the Titlebar. There are no Tabs in the Titlebar. ''Maybe there is something that I don't understand about the tabs-in-titlebar feature in 4.0??''
As it is with WinXP that is very unappealing to me, so I have a few Profiles that I am playing with that have different modifications that make better use of the Titlebar area. In one Profile I have all my addon Toolbar buttons in the Titlebar - https://addons.mozilla.org/en-US/firefox/addon/personal-titlebar/ - which places anything that is on the Menu bar into the Titlebar when the Menu bar is hidden.
Overall, I haven't used the Menu bar since like 2004 - to me it was always a waste of one toolbar worth of browser viewing area "real estate". I have been using the Compact Menu extension, and the various CM replacement extensions over the years since, to reduce the Menu bar items down to one button on the Nav bar that provides a drop-down menu, which can be activated with the '''Alt''', as the Firefox button / Menu bar now works. ''It could be said that I have been using the Firefox menu button for 7 years now - LOL.''
No browser that I have seen, except for Chrome, doesn't have an option to show a complete Menu bar - removing it completely would be a huge mistake, the option to hide is good enough. Firefox 4.0, Opera 10 & 11, along with IE8 did it a lot better than Google, IMO.
Between Google forcing that damn "updater" program on their users and not having a Menu bar at all, it's gone from my XP desktop and I haven't used it in any months on my Linux netbook.

Why don't you have a phone #. I want to install Firefox on my ipad2 and can't get an answer. Apple says Firefox is coming for ipad2...when?

I want to install Firefox on my ipad2 and can't get help. Apple says Firefox is coming for ipad2...when??? Why don't you have a phone# for support? Safari does not allow me to do what I need to on some websites. Help!!

Apple's rules for their app store do not allow programs such as Firefox to be run on their iOS devices. We do have a tool to allow access to your Firefox Sync bookmarks and history on your iOS device.
