Firefox bug? McAfee SiteAdvisor 3.7.1 jams at 50% CPU useage

Firefox 35.0.1
In certain circumstances, Firefox starts using too much time CPU. It seems to happen when you try to do too many things at once. But, once in this state out of functions (closing all tabs) except my homepage that Firefox is still stuck using 50% of the CPU and more than 200,000 k of memory. The only way out of this should close Firefox and restart.

After much experimenting, I found that disabling (extension) McAfee SiteAdvisor "cured" the problem. Is there an incompatibility here? Is there one fix other than to disable SiteAdvisor?

How can I report to the mozilla developers?

McAfee SiteAdvisor has been blocked by Mozilla several times over the years due to a large memory leak. Although not recently iirc.

It doesn't surprise me a bit that McAfee seems to cause problems for you now.

Overall, this extension simply duplicates the features that are built into Firefox. IMO, it adds nothing to Firefox, beyond a different data source, or even ' bells and whistles ' users to 'wow '.

  • Is there an add on for McAfee SiteAdvisor or it is disabled forever

    I use McAfee SiteAdvisor whenever I search. The new update for Firefox has disabled this feature... Is it active again, or is - that permanent. I love Firefox and I also like McAfee and use the SiteAdvisor when searching... I have put my trust in this site for years... So I'm hoping this will allow FireFox...

    I uninstalled the McAfee SecurityCenter and tries to remove the Siteadvisor. Uninstall lists McAfee Webadvisor program but will not uninstall it. I see 2 folders of pgm in Program files(x86) /McAfee: Siteadvisor and Temp.

    so far, your main problem is flash player, you must include the updates Flash Player with all the updates of firefox, oh and updated player get. It's your bug I 'think '. If it is not part of the territory firefox let me know. However, will not be broadcast live, I asked them, they had little info. including, you update your browser recently - with no answer to this question, so here I am. I don't know if the flashplayer or everything that has nothing to do with live stream or not, BUT quicktime play or help live streaming right? have no idea and the new mac user. GL

    Adobe Systems, Inc. (owner of Adobe Flash) is not related to Mozilla Org in any way. Mozilla has nothing to do with updates to the software they do not create or owned by another company.

    You have a very old version of Flash installed - Shockwave Flash 9.0 r47 - you must upgrade to the latest version available for Mac OSX 10.4.

    If you choose to customize the settings of your story and choose "Accept cookies from sites", but only "keep until: closing firefox" you'll find that cookies from http and https sites remain in Firefox after Firefox restarts.

    Please correct this immediately.

    This always works for me.

    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

    If the deletion of cookies did not help, then it is possible that the cookies.sqlite file that stores the cookies has been corrupted.

    • Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete the other files of cookies as cookies.sqlite - journal in the profile folder of Firefox in the case where the cookies.sqlite file has been corrupted.

  • What is the small icon of Firefox "bug" on the right side of the browser next to the menu?

    Menu to the right of the browser is a graphic or icon that appears to be connected to the combustion chamber. This icon is poorly equipped and distracting to the browser and seems to serve no purpose other than just being annoying.

    If it is displayed with the intention of Mozilla, take this comment as a complaint of dissatisfaction of your product, the Firefox browser.

    I have not yet try the Google browser, but if you're the "intuned' to the user experience, maybe it's time to give them a try.

  • Rendering in Firefox bug

    I'm developing a website (Joomla)-. It is still in the test stage, but it can be found on www2.kortrijkserefs.be.

    There is a problem in the section of the banner. Sometimes (about 20% of the time) one of the banners is moved to the next line, sometimes the banners appear 2 by 2 (which is the goal). It seems to happen randomly, while the source of the page is the same.

    I guess that the same source code would still make the same page, so I think there must be a bug.

    Some additional information:

    • All banners are the same size. The images are 480 x 80, Joomla settings are also all set to 480 x 80.
    • It lies with random banners. It is not a banner that is always involved. (I tested which at length.)
    • It seems to happen at random times. It seems simply never occur on the first load of the page. (It's just a feeling, no evidence difficult.)
    • I tried with another browser (a browser with a blue logo e-shaped): no problem, the rendering is perfect.

    Hi bdepaepe, I had a quick glance and I think I've experienced the error mean you and solved.

    The reason why this happens from time to time, but is not always because the source code is not the same thing every time, as the ads change each update. The error only occurs when two of the < div > tags of class "banneritem" who are on top of each other have a height of 84px each rather than 80px (although even if it's the case the display problem is not always the case).

    The reason that some of the 'banneritem' < div > tags have a height of 84px is inside them, there is a <>tag that contains an < img > tag and < a > tag has not been set ' display: block;'. < a > tags are inline by default, so should not be used to hold block level elements such as images, unless that include styles for the < a > tag ' display: block; ".

  • ActionScript loading in Firefox bug problem

    Help, please.

    I'm working on a page at http://localhost/skitterskatter/gerilance/D4D/index4.html

  • I don't want to upgrade to 5.0 until my antivirus plug-n software is compatible. How can I avoid that Firefox bugging me to upgrade every two days?

    The nag screen to get update's coming two everyday when I click on "ask me later". This is not 'later' in my book, it's going to take longer than two words for my av provider update their plug-ins, I bet.

    OK, I know in the grand scheme of things, it is not a big problem but the ffs, same Adobe can get their head round, offering you a choice of way well before you want to be harassed again. And they used to be really demanding!

    A beta version of Avast is available: http://forum.avast.com/index.php?topic=80428.0

    Or, as in the second post in this forum thread "You can also uninstall webrep of your current avast to have compatibility with FF5."

  • Firefox crashes (even in safe mode) constantly and use 50% CPU while doing

    I use Firefox 36.0.1 and Windows XP (32-bit version).

    Lately, Firefox made this weird thing where it stops randomly load anything, as if the connection has been broken (it isn't, any other works very well). In this case, Firefox uses 50% CPU, when it is usually revolves around, well, 0%. Restart the browser, or waiting for a few minutes "fixed" the problem temporarily. Same thing in safe mode, too.

    I have the feeling that this * might * be related to Flash, since it seems to happen more often when I am watching videos, or stream on the shaking. I tried to disable the plugin-container and update the Adobe Flash Player plugin, with little success. Malwarebytes could not find anything either, and it does not feel like a virus anyway.

    Whatever it is, I'm out of options at this point. I had a lot of problems with Firefox for a while now, especially when it comes to videos/animations (I can't play the videos of Vine.co , for example), and it starts to make it difficult for me. I really don't want to switch to Chrome, I don't trust of Google and their browser doesn't have a lot of key functions I like in Firefox (such as the sidebar bookmarks < 3), so I really hope I can get help here.

    Any suggestions?

    Chrome is a pain, I tried to go back and difficulty of Firefox (so far), and again, I think I found the problem. I should mention that I tried these 5 suggestions before, btw, and none of them got rid of the problem. Yes, even in safe mode, with a profile is empty, no plugins, no firewall and without tab, it happens again, somehow. And Yes, Chrome will work fine with Firefox running in the background, as I mentioned in my previous post.

    What he did for me was turn off Prefetching and IPv6 times in all: config, following the instructions on this this page .

    I'm not sure that one did the trick (I kinda afraid to mess with that again, but I could test if you want to, it might be useful to others), but it looks like everything is going well for the moment.

  • Firefox does not start (not safe mode), but uses the CPU

    I have the latest Firefox 25.0 (and the last Flash 11.9.900.117) on Windows 7 and the following behavior is reproducible. It started not too long ago.

    At first when I launch Firefox, nothing appears no matter how often, I restart. I see in the list of the process firefox.exe to 25% of the CPU, 2 x FlashPlayerPlugin_11_9_900_117.exe (CPU 0%) and plugincontainer.exe. No matter how many times I killed all of them, would not restart Firefox.

    The following also not help in this situation:

    • Starting in normal safe mode: Firefox opens a window but immediately freezes and does not respond. The process list shows the same process even if I find the unexpected FlashPlayer.
    • Disable plugincontainer: same results (just without plugincontainer.exe)
    • Uninstall Flash: Same results (just without FlashPlayerPlugin)

    The following can start Firefox only once:

    • Starting in SafeMode but select "Reset Firefox": Firefox does not start right away, however. Nothing happens, and you have to kill the process. However the very next time you launch Firefox in the normal way, it works fine (but it shows FlashPlayerPlugin.exe in the list of unopened Windows process despite the tab). Unfortunately, after closing Firefox the process (Firefox, FlashPlayerPlugin) are not deleted. I kill and the problem with Firefox do not leave reappears.

    In case you use "clear history of Firefox closing:

    • do not delete Cookies

    Note that compensation "Preferences of Site" clears all exceptions for cookies, images, windows pop up, installation of software and passwords.

    Use "Firefox > output" (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit) to close Firefox if you are currently doing by clicking on the X close in the title bar of Firefox.

    Create a new profile manually (and not via the reset) as a test to see if your profile is the source of the problems.

    See "create a profile":

    If the new profile works then you can transfer files from a profile in the new profile, but be careful not to copy files corrupted to avoid transporting on the problem.

  • FireFox crashes on a regular basis with 100% of the CPU. All the Add-ons and plug-ins disabled.

    FireFox hangs on me regularly with 100% CPU usage. I have add all and disabled plugin. In safe mode I don't have the problem. Don't know what to do next because I have disabled all add-ons and plug-ins.

    OK I fixed that by disabling 'Use hardware acceleration when available' in the 'Advanced' Options I had to restart FireFox for the changes to take effect.
