Firefox consumes CPU when displaying static pages

In the Windows Task manager I see that the Firefox.exe process consumes constantly 7 to 18 % of CPU even if I display a static page.
E.g. Now when entering t6his message on the Firefox Help page, I have only 1 Firefox window and Tab open. The Firefox.exe process consumes 14 to 18 % of CPU.
I have noticed this since several months on several computers.
Why does Firefox consume constantly a significant part of CPU ?
Could it be due to some malware ?

See https://support.mozilla.org/kb/Firefox+consumes+a+lot+of+CPU+resources
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Firefox 9 stalls when loading static pages, how do I fix it?

Windows 7 Firefox 9 beta worked fine up to about three days ago, now stalls loading static pages. Seems like Foxnews sites in particular. Have cleared caches and cookies. disabled realplayer with limited improvement

Try the Firefox SafeMode. 
''A troubleshooting mode, which disables most Add-ons.'' 
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. 
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one.

Is there any way to edit the standard Firefox context menu for displayed Web pages?

Is there any way to edit the standard Firefox context menu for displayed Web pages? I frequently want to save a picture appearing on a page. Sometimes I "slip" and hit "Send Image" when I want "Save Image As", and have to sit and wait for a default send-mail page to come up, then close it, fiddling with its "are you sure" dialogs. This is a painful way to handle a slip-up. I basically NEVER want to e-mail an element directly from a page. Is there any way I can just delete "Send Image" from the context menu?

You can remove entries in the context menu with code in the userChrome.css file

Firefox 11.0 incorrectly displays web page

Rev 11.0 will not display this page. Using this URL will open a blank window. In Safari, the window has information in it. I would post this as a bug report but cannot figure out how to post a bug report.

This is what I get if I open the Web Developer > Web Console (Cmd+Shift+K),

Set isolatedHtmlContainer height when displaying portal page

Hi,
I have a portal application which displays portal pages from the pcd in isolatedHtmlContainer.
The page's content is dynamic so the height is not fixed and therefore in the page's properties the height's value set to 'Automatic'
However, when working with isolatedHtmlContainer the height could be set in pixels or percentage only (I cannot set it to 'Automatic').
p.s
If the height was fixed I could get it by the profile of IPortalComponentContext, but if I will do that I'll get a string like 'Automatic' which doesn't help me...)
Thanks,
Omri

Hi Martin,
I read the blog but the javascript doesn't affect my IsolatedHtmlContainer.
Let me rephrase my question:
In the portal innerpage I display X IsolatedHtmlContainers (my application decides how many pages to display). Each container has dynamic content (a portal page from the pcd), therefore, I have a problem setting the height of the IsolatedHtmlContainers (too low - scrolling bar, too high - blank space).
The properties of the portal pages from the pcd are set as follows:
isolation method - URL
height method: Automatic
If I display the pages without the IsolatedHtmlContainers, the 'Automatic' feature works and the page's size is OK.
So my question is:
Is there a way for the IsolatedHtmlContainer adjust its size according to its content?
Thanks,
Omri

Firefox uses too much CPU when displaying flash sites

When I have a site with flash and/or java open, firefox uses minimum 40% of my CPU power, even when I'm doing nothing, when firefox is idle and waiting for input.
P.S. This could be a recent issue, probably related to the newest version of firefox, however I haven't tried downgrading it because I don't have the old version package in my cache. (cleaned it a while ago)

Of course it is, but there isn't much we can do about it, isn't it? Therefore I suggested firefox3, to alleviate things a little (it does it for me). Flash doesn't even work at all for me in Opera, I only get a grey window where the video should be.
Bye, signor_rossi.
The newest version of flash Plugin only works with Opera 9.5 beta. If you want to use flash with the stable Opera find an older version of the flash plug in.
Thanks for the hint, will keep that in mind in the case I will switch to Opera again (used it for a while because Firefox2 scrolling was bad, with 3 it is much better). Besides, there is a new flash version in the repos.

Firefox sometimes freezes when loading new pages

I have had an issue for several months now & any help with it would be gratefully appreciated.
Quite often, when loading a new page, Firefox will hang for up to 30 seconds; the loading circle in the left hand corner of the tab will freeze & I will be locked out of the browser. That website's usually then fine for the rest of the session, but if I close and reopen Firefox the same thing will happen again.
I have tried other browsers such a IE, and the same thing also happens there. My laptop is becoming quite claggy in general, but I'm hoping I can at least find a solution to this!

Do you get a dialog saying a script is running slowly with Stop/Continue buttons, or does the problem just clear up without any messages?
Two other thoughts:
(1) To diagnose a possible Flash issue, you can switch the Shockwave Flash plugin to "Ask to Activate." The page should load the non-Flash components first. If it's just as slow, then we can rule out Flash as a potential culprit, but if it's much faster, that would be useful to know.
You can make the change on the Add-ons page. Either:
* Ctrl+shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Plugins. Then use the drop-down list for Shockwave Flash to select "Ask to Activate."
Sites that use Flash will generate a notification icon on the address bar, and either a link will appear in the black rectangle where you normally get videos loading automatically, or an infobar will slide down between the toolbar area and the page.
(2) About 8 months ago, a user with an enormous font collection discovered that when visiting pages that use downloadable fonts for the first time during a session, Firefox would hang for 3 minutes. ([https://support.mozilla.org/en-US/questions/957111 Firefox hangs on Websites (example: g2play.net)]) I don't know whether this is still a problem, but if you have tons of fonts, as a diagnostic, you could temporarily disable downloadable fonts.
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box that appears above the list, type or paste '''gfx''' and pause while the list is filtered
(3) Double-click the '''gfx.downloadable_fonts.enabled''' preference to switch its value from true to false.
I say temporary because many sites now use fancy fonts to display little icons instead of using images. With downloadable fonts disabled, these icons turn into tall rectangles with two rows of two characters (in other words, useless).

Tried everything, and Firefox still will not display web pages correctly. Please help!

I'm running the latest version of Firefox, and it recently started to lag. I was looking through these forums for an answer, and a bunch of people recommended to reset Firefox. I did so, and then the browser started to act very weird. When I go to websites such as Facebook and Youtube, it's just a bunch of black text along the left edge of the page. No images, and no illustrations like usual. All of the pages work perfectly in different web browsers, so it must be a problem with Firefox. I've tried everything under the sun to fix it, but still nothing. I tried re-installing, deleting the cache and cookies, and managing the privacy settings for the app. I really want to get Firefox back to normal, ASAP. Any help would be greatly appreciated. Thank you! :)

What are your cookie settings?
*Tools > Options > Privacy > Firefox will: "Use custom settings for history"
You can inspect and manage the permissions for all domains on the about:permissions page.
*https://support.mozilla.org/kb/how-do-i-manage-website-permissions
You can inspect and manage the permissions for the domain in the currently selected tab via these steps:
*Click the "Site Identity Button" (globe/padlock) on the location bar
*Click "More Information" to open "Tools > Page Info" with the Security tab selected
*Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab
Delete the permissions.sqlite file to reset all permissions.

My firefox browser closes when loading any page without a crash report

My broswer keeps closing when loading. No crash report pops up, it just takes me to the "well this is embarrassing..." page that asks if I want to restore, to which no matter which option I pick it keeps closing on me.

clearing cache, and cookies only removes the cookies and clears the
cache/ Not passwords or anything else. Closing in safe mode? That tells
us something. Now do this, 
1) '''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' 
2) '''''Firefox > Add-ons > Plugins'''''. Disable '''EVERYTHING''' ! !
If Firefox closes on you, start it again and keep going. After everything is
disabled, restart in safe mode again. And let it sit for a while. 
3) Look at the list of programs below and run at least 3 of them. Each
program works differently so what one may miss another could pick up.

My firefox has suddenly stopped displaying web pages only instead the full HTLM

My Foxfire 3.6.13 stopped displaying webpages in full HTML and now only displaying them in text. Like for instance, my homepage is set for www.earthlink.com, but instead displaying as a full HTML, Firefox displays as TEXT page. I don't doing anything my Firefox settings to change this; so what do I do to get it back?

The screenshot didn't attach.
Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).

Firefox very slow when first loading pages from new domains.

I've noticed that when starting the browser or opening up a new site it takes a considerably longer amount of time to load all the JS and assets compared to Chrome. Typically an extra 10 to 20 seconds, which is seriously annoying and nontrivial. After I've loaded the first page from the site Firefox is usually pretty fast on loading new pages from the same domain.
Firefox also sometimes fails to render CSS, resulting in a white page in Times New Roman and misplaced images.
I've tried setting up a new installation of Firefox and it hasn't solved the problem. Also tried Firefox portable with no addons and I got the problem straight out of the gate. It seems to be a problem with the code as Chrome and my internet connection work just fine. I've tried using Google as my primary DNS (8.8.8.8) which hasn't changed much.

You can try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need close and restart Firefox after toggling this setting.

Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Firefox, unlike IE, is displaying my pages in very small print that is hardly legible; please help.

My website consists of 6 pages, and on Firefox, 2 of the pages show the printing very small. On both pages, the printing occurs within a white box. It does not happen on Internet Explorer. I have no other browsers, so I don't know about any others. But, I know Firefox is popular, and I would like all the pages to be legible on Firefox. Can you help me?

Safari and Firefox calculate relative font size slightly differently than IE and Opera do.
'''font-size: x-small''' is what you specify as font size. Try using '''12''' or '''14''' as a specific size for the font, rather than a '''''relative''''' such as x-small and large.

Url iview showing error when displaying a page with frames

Hi,
I have a requirement of putting a site in a url iview in the portal. I created a url iview and when I preview it, it displays correctly. When I assign this to a role and access it through the navigation, it gives an error.
The weird thing is that, it works sometimes and it does not work sometimes. The url I am trying to display is working fine, because even when the portal shows error, if I try the url straight from the browser, it loads without any errors.
So what could be the problem? The site I am trying to display contains frames. Could this be the problem? If so, why is it working sometimes and does not work sometimes?
Thanks in advance.
Regards
Ranjith

Hi Martin,
The issue is still there. But one interesting thing that was noticed by my team mate was that if you add the site to the list of sites on browser which can use cookies, everything works fine. Similarly, if I reduce the privacy setting of my browser to Low, it works fine.
Again, even if you keep the privacy setting as Medium and does not allow the site to use cookies, the iview opens fine if you open it in a new window.
Any thoughts on this?
Thanks & Regards
Ranjith

Flash plugin for Firefox/Opera (Suse 10) displays partial pages

In quite a few pages, including toyota's website
http://toyota.com/vehicles/2007/sequoia/index.html?s_van=GM_HOME_FLASH_SEQUOIA
the page is displayed incomplete

That's what I was afraid of, thanks. That however brings two
more questions
1- Is there a way to see which version was used to build a
site?
2- Is there a timeline for releasing flash player 8.5 or 9
for linux?

Firefox is crashing when loading specific pages.

I've tried disabling and re-enabling each plugin, I've downloaded the newest version of Firefox, and ''nsBrowserOpt.dll'' doesn't seem to be the problem. My computer recently (like two hours ago, haha) crashed and rebooted using Microsoft System Recover with a recovery date of February, if that has anything to do with it--prior to the computer crashing, Mozilla had a lot of hang-ups, but no crashing. I suspect malware, but I'm really not at all sure, because Norton keeps coming up with that little window that says "A recent attempt to attack your computer has been blocked." which is slightly unsettling. But I don't know where to go from there.
I'm really terrible at computers.
