Recently my Firefox browser has started to shake whenever I use it.

Just recently it seems that every time I start up Firefox the browser is jittery and I can't click to anything because the browser is constantly moving. There is nothing wrong with my monitor as I am writing this using Internet Explorer and everything is fine. I tried uninstalling and downloading Firefox again and the same thing happens.

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.

My Mac has started lagging badly whenever I use Flash.

I've got a 2.4 GHz MacBook Pro 7,1 with 4 GB of memory running OS X 10.6.8 and recently it has started lagging severely whenever I open a flash video or game. I use to never have any problems playing games on my computer or streaming any video, even up to 1080p.
Then, recently, it started lagging whenever I used flash, and it's bad enough that my cursor begins jumping, scrolling is basically impossible, the video only shows a frame every few seconds and it **** near crashes my entire computer. During these times the % CPU for flash in activity monitor will jump up to over 100.
This issue has really started to bug me and I've tried everything I can to fix it. I've downgraded to older versions of flash, uninstalled and reinstalled Google Chrome, done all of the system updates for my computer, but nothing works. I just wanted to know if there's any way I could fix this to have my computer back in working condition. Any help would be greatly appreciated.

I am having the same problem, and it's driving me crazy! I have the same macbook as chrispy17, except with Lion. Does anyone know how to fix this?

my money is on a hardware issue

Downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in Safe Mode even though I have shut down and restarted my computer several times

I have Windows OS. I downloaded Firefox yesterday. Every time I open the Firefox browser, it starts in safe mode. I have restarted my machine several times -- Firefox still starts in Safe Mode. My favorites from IE copied to Firefox fine, and Firefox is now my default browser...it just keeps opening in Safe Mode.

I downloaded the toolbar. When I was done using the computer, I put it to "sleep." The next time I "woke" the computer and went to Firefox, the toolbar was gone. When I downloaded the toolbar again, I got a box in the upper left hand corner of the screen stating Firefox BLOCKED the toolbar, and did I want to allow it. There was NO option to allow always-it's just a one time deal. When I shut down for the day, I expected it to remain, but no-next time I fired up firefox, NO TOOLBAR. I pulled up Inbox dollars again, clicked on download toolbar, got the box stating it's blocking the toolbar, etc, etc, etc. Unless Firefox upgrades daily, or in some cases, several times in one day, I'm going to stick with my description that the toolbar magically disappears EVERY TIME I OPEN
FIREFOX!!!
I don't profess to be any type of computer whiz, I'm totally self-taught, and it's not beyond the realm of possibility that I'm doing something wrong. I've been using Firefox for about a week, so I'd welcome any help!

Within the last week my firefox browser has been freezing and loading a lot of pages. Very slow. I've uninstalled, I was getting a yahoo search. I've set the i

I have been a firefox user for 15 years. lately my browser has become really slow and freezes everytime. my bing and google browsers are not having problems

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information such as bookmarks and History.
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.
Also try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Viewing a pdf in Firefox browser has white lines. How can I fix the problem?

Viewing a pdf document in the FireFox browser (other browsers the document is fine) shows white lines though the pictures. I have tried different ways to save the document (printing or save as) as a pdf and I either get white lines or missing content while viewing on Firefox.

Please update to the latest version of Firefox.
*[[Update Firefox to the latest version]]
Also make sure that your graphics card drivers and WebGl drivers are up to date
*[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Which pdf viewer are you using?
In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:
#Click the menu button [[Image:New Fx Menu]] and click Options (Preferences for Linux and Mac).
#In the Options (Preferences for Linux and Mac) window, select the ''Applications'' panel.
#In the ''Search'' field, type ''PDF''. You should find ''Portable Document Format (PDF)''.
#On the right hand side you should find an ''Action'' column. Use that to select your favorite PDF reader. In order to view PDF files in Firefox, choose ''Preview in Firefox''.

Firefox won't start on windows 7. Used to word when it was on version 18. I have different windows 7 machine it works fine on that.

firefox won't start on windows 7 after upgrading to version 19 or 20. Even if it starts up I cannot do anything on it, its in not responding mode. I have tried uninstalling and installing again with both version 19 and 20. Also i tried deleting the profile and re creating a new profile.

it does not work even in windows safe mode with networking. same issue. if i wait for some time firefox comes but in not responding mode. then a pop shows up with - script: chrome//browser/content/tabbrowser.xml 2123 .

Firefox does not start (not even safemode) but uses CPU

I have the latest Firefox 25.0 (and latest Flash 11.9.900.117) on Windows 7 and the following behavior is reproducible. This started not too long ago.
At first when I start Firefox nothing appears no matter how often I restart. However, in the process list I see firefox.exe at 25% CPU, 2x FlashPlayerPlugin_11_9_900_117.exe (0% CPU) and plugincontainer.exe. No matter how often I kill all of them, Firefox wouldn't restart.
The following does also not help in this situation:
* Starting in normal Safemode: Firefox opens up a Window but freezes immediately and does not respond. The process list shows the the same processes even though I find FlashPlayer unexpected.
* Disable plugincontainer: Same results (just without plugincontainer.exe)
* Deinstall Flash: Same results (just without FlashPlayerPlugin)
The following can start Firefox once only:
* Starting in Safemode but select "Reset Firefox": Firefox won't start right away, though. Nothing happens and you have to kill the processes. However the very next time you start Firefox the normal way, it works fine (but it shows FlashPlayerPlugin.exe in the Windows process list despite not Tab being open). Unfortunately, after closing Firefox the processes (Firefox, FlashPlayerPlugin) are not removed. I kill them and the trouble with Firefox not starting reappears again.

I'm afraid not. As soon as I reset, Firefox disappears however two new FlashPlayerPlugin.exe processes start. Those together with firefox.exe remain as background processes and above cycle is the same.
There is one difference between resetting in safemode-startup (Shift clicking while startup and chosing "Reset") and resetting from the Troubleshooting menu: Only the former allows for a subsequent single normal start (after killing the first attempt as described above).
PS: My extensions did not get lost. Does that mean the "Reset" actually crashed? Also I'm using Sync.
PPS: I've tried disabling all Plugins (Flash etc.). Now when I close Firefox, FlashPlayerPlugin does not remain as a process, however firefox.exe does at 25% CPU. And when I try to restart Firefox, I again get two FlashPlayerPlugin processes with all the above symptoms (Plugins remain disabled in the configuration). This plugin is probably not the cause as I also tried deinstalling it, but it may give an indication where Firefox gets stuck.

I have a MacBook running a 10.7.5 OS. Of late it has started hanging, especially when I use Safari. Can anyone help?

I have a MacBook that's four years old, runs on iOSX 10.7.5 but of late has been hanging, especially when I use Safari. Can anyone help?

Carolyn,
I searched my whole system and couldn't find
com.apple.systemuiser.plist
So that is a mystery. However the part about:
Go back to System Preferences > Network
Make sure the box is selected next to: Show Wi-Fi status i menu bar. Solved the problem. Somehow the box had been unchecked. Gremlins I guess!
Thanks so much for your help.

My Firefox browser has a pure black line running through my Firefox persona. How do I get rid of it?

It's hard to explain. On the top of the browser, where my persona is, there's this pure black, centimeter thick line. It's not transparent, it's solid. It has been there since I downloaded Firefox a couple monthes ago in February. I thought that maybe it would have gone away by now, but I don't know what's causing it in the first place.

Hi sbla, seems like you are having some kind of plugin or even a virus that opens those popups. Please try to disable all your Firefox plugins and if that doesn't help, run a virus scan.
Do you know of a Mac virus that pops up a dialog in FireFox, I don't, can you tell us what it may be?
There are no Mac viruses, this may be a plugin but they get there because they are installed by the user.

My Firefox browser has become corrupted by bannersdontwork popups and I will, sadly, have to quite using it.

Firefox opens on my homepage, but whatever item I click on, a full-page popup appears asking me to answer a survey or promoting some service or product. I have used Firefox for years, but this madness is driving me back to Internet Explorer.

hello, this sounds like a problem possibly caused by adware on your pc. please go to ''firefox > addons > extensions'' & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

After recent upgrade, Firefox won't start. Just flickers once when I click on a link or on its icon.

My version is 32. "Best Solution" says click the upgrade button to get v34. But I can't do that if FF won't open.
I have Mac OS 10.9.5

You can check if you can start Firefox in <u>[[Safe Mode|Safe Mode]]</u> by holding down the Options key.
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> 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
