Ever since Firefox 18.0.1 I can not do the automatic check of plug ins. I go to the Add On Manager, click on "Check if your plug ins are up to date" on the left upper corner and then Firefox freezes. Getting a "This program is not responding" message. I can do the check for updates on plugins but I can not go to the pages where the add ons are checked.

Flash just started causing Firefox to freeze (not crash, therefore; no crash id's (Correction Below)). It was working fine until an hour or two ago. Also, Firefox now freezes on other sites. This just started less then 30 mintues ago. It seems, there are a few ways to 'temporarily' fix the issue, but it always occurs again immediately. First, if I use task manager to end the Adobe Flash process, Firefox unfreezes. Second, as far as it freezing on other sites, the only way to unfreeze Firefox is to end task on the Plugin Container for Firefox process.

I find it weird that this just started happened with no cause. I have not made any changes to my computer in months (neither software nor hardware wise) and I know I don't have any virus' or the like as I keep that very well in check.

As far as what I have done to 'attempt' fixing this issue, I have already tried updating Flash, downgrading Flash to 10.3, upgrading Flash back to 11.x. Restarting Firefox, rebooting the computer, booting into safe-mode, running Firefox in Safe-Mode, uninstalling & reinstalling Firefox (with a reboot in between). Nothing has fixed this issue. Any help would be very much appreciated.

P.S. I have no issues of any kind in IE, Chrome, nor Opera so I know this is a Firefox issue.

P.P.S. Checked about:crashes and found that Firefox actually made crash information on the flash plugin (but don't see one on the plugin container issue). Anyways, it was throttled so sent it on. Here is the information on that;

Keep in mind, this was before I reinstalled Firefox, no new entries since reinstall.

This problem only occurs in my laptop not on desktop. Both of them brand new and this problem occurs when there is a new version of firefox. I always do a manual update when I know there is a new version of firefox. I update it and it brings up the new version.

But when I go to add/remove program I can see there's two version of firefox i.e. Firefox 18.0 and Firefox 18.0.1. So I have to again uninstall firefox and download and re-install firefox. Why is this the case? For the desktop it doesn't happen like that? When i do a manual update from desktop it install the new version and in the add/remove program i can only see version 18.0.1.

I have FF 18.0.1 running on a VISTA Home Premium system and whenever I enable the Norton Toolbar (2013.2.1.36) -- updated as of 1/20/2013), FF always crashes when I close the browser. The only way I can prevent the crashes is to disable the Norton Tool Bar. All of this worked find prior to FF 18.0

I have been to the Norton Community website and there are multiple posts about this, but to date, the problem is NOT fixed. Norton adms apparently are aware of this problem.

Does anyone in the Mozilla community know when this will be resolved and who has ultimate responsibility for fixing it -- Mozilla or Norton?

I also have a Windows 8 Pro system on a laptop--and there is NO problem whatsoever there.

Hi,

Whenever I move the mouse in Firefox 18.0.1, the firefox.exe process jumps from 0% to 30% CPU consumption. When other stuff happens that requires CPU resources I experience a drop in responsiveness, so please don't tell me that 30% is acceptable ;)

I made a default profile to test this. I also disabled plugins and tested in Firefox safe mode. I'm running a 3 days fresh install of Windows 7 64 bit, fully updated. I installed Acronis True Image 2013, if that matters. Firewall and antivirus are disabled. Slowdown occurs even on about:blank pages, however when I'm moving over Firefox options pane, CPU jumps by 10-15% instead of 30%, which I guess is a little more acceptable.

It doesn't happen with Internet Explorer, whether 32 or 64 bit. It doesn't happen with any other program, though few are installed, except a 10-15% increase in Kaspersky Antivirus 2013 UI. I personally don't expect more than 5% increase in CPU consumption when I move the mouse over something. Kaspersky menus are way more animated than Firefox though, so I'm not sure the consumption I report is related to my issue.

My mouse is an EssentielB, model Mulo XL, product code 825258. It's a wired laser USB mouse with 2 extra buttons that do previous/next in Firefox, and 2 other buttons that change mouse speed.

It didn't come with any separate driver, was automatically recognized by Windows and works fine. However I'm using a laptop, and moving the mouse cursor with the touch pad increases CPU consumption by 10-15% instead of 30% with the mouse. (as I said, this is better but still a lot)

Hope you can help! :) If you need more info or that I test something, please post here instead of emailing me as I do not check that mail box. Thanks!

EDIT: The troubleshooting information says 0 / 1 window is hardware accelerated, but that's only because Firefox was running in safe mode. In normal mode the problem of course persists yet hardware acceleration works properly.

if firefox is open and system goes into standby, whe I return from standby (press power button on front of machine and then log in) firefox is unresponsive. Sometimes it will go to a new web page if I click a link in the open page, but the link fails to change color. And it is very slow. Other times it is completely unresponsive. I have to close it and then restart it to get it to work. All open tabs are then lost. Tried resetting and disabling all add ons/extensions. problem began when updated to v18.

Bookmarking suddenly stopped working yesterday.

When I add a page to bookmarks, and select "Choose..." for Folder, the next dialog, where I am supposed to select the target folder, has empty list of folders (I am talking about the "big" list/tree). The drop-down box above the list still contains all standard and last used folders, and is functional, but nothing else. The "New Folder" button is also disabled. The bookmark still will be created in one of those selected folders, and it will also sync. Bookmarks manager, as well as Bookmarks menu both work fine.

I have tried disabling all plug-ins, and deleting localstore.rdf, but these did not help. I do not remember installing any new plugins either.

9 out of 10 times my download gets truncated in Firefox. For example, let's say I was downloading a 42.2 mB file, it would get to about 42.18 and then complete. I would then try to open the file to find it was corrupt. I would then open up IE9 and download the exact same file, and I would get the full 42.2 mB and the file would open flawlessly. I have tried disabling all extensions/addons, nothing. I have reinstalled Firefox cleanly a few times, no dice. I have tried disabling any file system protections I have, nada. I'm at a loss right now as to what else I can try. I love Firefox, I've been using it since it's original release, but I need to be able to download. Every other browser I've tried works great in that department, except for Firefox all of a sudden. Anyone have an idea?

Since FF auto-updated, Priceblink doesn't pop up while shopping. Also, FF seems to hang periodically when I attempt to go to any site. I uninstalled/reinstalled Priceblink to no avail.

Windows 7 Professional 64-bit FF 18.0.1

My home page is set to www.yahoo.com When I click on the home icon (or type the same address in the Address bar), the address bar changes to http://www.yahoo.akadns.net/ and the server not found ff built in error page displays I have the live http headers add-on, and there is no actual http request sent.

FF simply will not let me reach www.yahoo.com by typing in the address bar, it always 'rewrites' the address as http://www.yahoo.akadns.net/

I can reach www.yahoo.com in other browsers, via dns (nslookup), and other yahoo addresses (e.g. my.yahoo.com). This sure sounds like malware and is a bit frightening

when I click the new tab button on firefox, instead of bringing up the usual page showing what I usually go to, instead there is a white page (no HTML at all) there are no new extensions running and I have done many checks for any malware and bloatware on my computer with none found. I simply can't figure it out.

I have a new laptop, and i am frustrated. I have installed Waterfox (cause of 64 bit version), sometimes it works, but in the evening, it won´t. Then I installed Firefox, but it´s the same as Waterfox. Is it possible, that both are not good for Laptop or Windows 8? My PC works right with these browsers.And then I tried the Private Browsing, it works with both browsers. I can´t understand it.

1. I open Firefox and get a message to upgrade (I'm on 18.0.1). 2. I download the 20.0.1 upgrade and install it. 3. I check Tools/About and have successfully upgraded to 20.0.1. 4. I close Firefox. 5. Goto step 1.
