after updating to firefox 29 and then 29.0.1, the cpu usage that firefox are using are insane,

it ranges between 50%-100% cpu usage.

and it happens even on normal non flash tab,

besides even if the site is using flash, i am using flash block and adblock plus,

so anykind of flash material wont play or uses cpu.

please fix this ASAP, because firefox has now gone from useable to resource hog,

oh and i don't like the new look, because firefox has become more similar to chrome on User interface,

and i don't use chrome, because i don't like the UI, and now firefox tried to be chrome twin ?

i think that's all, thanks in advance.

edit : fixed some typo

After updating to Firefox 27 all webpages take a few dozen seconds to several minutes to load. When loading a webpage Firefox's status displays "connecting" and the CPU gets maxed out with 95 to 100% of its cycles taking by Firefox.

The computer is older so it is a little slow but Internet Explorer 8 has no trouble opening the webpages and neither do other computers on the LAN so it is not a network issue. I have tried restarting Firefox, disabling add-ons, deleting add-ons, disabling hardware acceleration, restarting the computer, and reinstalling Firefox after wiping every trace of it and its user data from the hard drive and registry.

CPU: AMD Athlon 2800+ 2.08GHz RAM: 1GB OS: Windows XP Home Edition Service Pack 3 32bit

I print several EBAY labels a day. Just upgraded to firefox 29 (not realizing really what had changed - now regretting) and the built in PDF viewer no longer prints properly. It shows the label fine on the screen, but when sending to the printer (I tried two different ones) it just prints out two blanks pages. I tried a number of different printer settings and as i mentioned two different printers. Can't get anything to print now except two blank pages. If I switch the application settings in firefox to use an external 3rd party PDF viewer (e.g. Adobe reader 11, PDF Viewer plus, etc) those work fine. However, the default built in PDF viewer clearly broke in this new version. A very disappointing launch for me as this is critical feature for my use. Yes, I have a work around, but the point (and new bug) is still valid.

- Session restore brings up tabs that I had closed before closing Firefox. Sometimes it even selects a tab that I didn't have selected when I closed it.

- Leaking memory like nobody's business. It went from 500 MB to 1.5 GB overnight (i.e. while it was "idling" minimized on the desktop).

- The config.trim_on_minimize setting is missing. Why is this?

- When the memory usage gets above ~1 GB (FYI, this is a guess), I start seeing problems with Firefox displaying web-page graphics and even, in one instance, shutting down text input on a web page (this was within Facebook).

- Randomly crashes for no apparent reason. FYI, this happened after I updated to Firefox 28 as well.

None of these problems ever happened before I upgraded to Firefox 28 and 29. I'm very close to abandoning Firefox altogether if these problems are not resolved promptly and permanently. In other words, I've nearly had enough of this. Whatever happened to "If it ain't broke, don't fix it"?

So recently my Firefox browser has been leaking memory like crazy going up to 1.7 GB in used RAM. It starts off fine when I first open it, but progressively gets worse over time, making scrolling a choppy and painful task. This started with version 28.0 but I've since upgraded to 29.0 and the problem persisted. I've done hours of research on the problem and have tried all the following solutions, to no avail:

- Turning off hardware acceleration/smooth scrolling/auto scrolling - Creating a new profile - Completely uninstalling and reinstalling Firefox - Running it in safe mode (still lagged, even in safe mode!)

Has anyone found any real solution to this problem?

(For Forum Moderators: Please read /forums/forum-moderators/710264?last=59300)


Moderators, please read first before closing/removing this topic right away?
To those wanting to react here on this topic: please, also read ;)
Since my original posting https://support.mozilla.org/en-US/questions/997009 was closed because one of the moderators felt it was going off-topic (although it was red a lot and had 131 "have-this-problem" in just a few days), here a kind of re-opening but on-topic.
Why? Because I feel we have the right to express our feelings on this major change. And publicly there is actually only this forum where that can be done on the Mozilla.org domain.
Sure, the change is there and we have to live with it (if we choose to). But that doesn't mean we can not have our voice here because after many, many years of supporting FF with our use, we suddenly are facing a layout we were always running away from.
So yes, that can cause ranting and so on (within the forum rules of course) because people feel strongly about there beloved browser.
(edit rules link note the whole topic is ordinarily outside the scope of the forum ... Posts in the Mozilla support forum must be either questions about the use of Firefox, ... Users who post about things other than Mozilla support will be directed to an alternative discussion place .... . ~J99)

Plus this way you can centralize all the negatives here instead of a lot of separate postings about the same subject ;)
To the people reacting here in this topic: there is only 1 real way to let Mozilla itself know how you feel on the new lay out and that is not through this forum. The way is to go to https://input.mozilla.org/feedback/ and let it know there.
edit You need to use a supported Firefox to post Feedback so that will soon not be possible from Fx28 2nd edit. I was wrong feedback works with any version of Fiefpx now~J99

And I think when that is done in normal words (so no f*ck you rants and so on) and suggestions, then maybe, just maybe, it has some effect.
Also, there is an Mozilla support page with info on how to get the "old look" back, see How to make the new Firefox look like the old FirefoxBut it will only partly restore the old look, certain FF29 things can not be changed.

And yes, I myself am back to Firefox 28 which is not supported or suggested by Mozilla because it has things (bugs and security) that are not fixed in it. (Edit Please use Official downloads if you must downgrade links in Install an older version of Firefox and the growing list of exploits you will open yourself up to is listed here: https://www.mozilla.org/security/known-vulnerabilities/firefox.html ~J99)

I am not suggesting or advertising to others to do the same. It is a risk I am willing to take and only say it is an option.
edit My reason to go back to FF 28 is because that version still has the intuitive feel and look Firefox one was praised for. With a logical lay out and a good way to simply customize it (also in about:config).
For those who say/think "Come one man, stop whining! Grow up and just accept that Firefox has to go with its time!", to them I say: nope ;)

I Just got a new Dell XPS Dimension PC w/Win 8.1. It didn't have Firefox, so I downloaded it (version 29.0.1).

Nearly every time I try to attach a document, e.g., a photo, or other file, Firefox crashes. The crash occurs when I double-click on the directory and/or folder that has the document I want to attach. I have submitted over half a dozen crash reports the last few days.

Instead of double-clicking, I tried simply clicking once on the OPEN button that appears when I ask to attach a document. This reduced the frequency of crashes, but, did not eliminate them.

The crashes have occurred when i was attempting to attach a document to an email in yahoo mail. The crashes have also occurred when I was attempting to add a photo to a news article i was writing for Examiner.co using their publishing tool.

I just switched from Windows XP. Firefox NEVER crashed when i was trying to do this in XP.

I tried to duplicate the problem in Internet Explorer 11, which came with my PC. I have not been able to duplicate the problem with Explorer.

What is going on?

Firefox (Version 29.0) keeps crashing on me several times per day. I have done the following to try and fix it but it still crashes. I was better off on the Aurora it seems.

Add-Ons: I tried disabling them but Firefox still crashed. I only have 2 extensions installed.

Plugins: I have checked all my plugins and it says that Adobe Acrobat (Adobe PDF Plug-In For Firefox and Netscape 10.1.9) is vulnerable but when I go to update it, Adobe tells me that I already have the latest update installed. The same thing for Java Deployment Toolkit 7.0.550.14 & Java(TM) Platform SE 7 U55. I go to update them and Java tells me I am already up to date.

Reinstall & Safe Mode: I have completely uninstalled then re-installed Firefox along with trying Firefox in Safe Mode. It still crashes.

Engineers are working on issues that have been identified.
The known issues are problems with Firefox hanging on closedown resulting in Firefox not restarting unless the hung process is killed.

Workaround ensure Firefox is NOT set to clear History on Close down

No matter whether I'm going to an address, typing into a box, or waiting for a website to load, the Mac "beach ball" will spin for a few seconds before loading. I use the default theme. I have minimal - (Xmarks and Trend micro), which weren't a problem before. Is there something I can do besides disabling the add-ons?

Like so many others, I find the ongoing and worsening memory leaks a real disappointment -and now getting worse since V28 on both of my W7 machines.

I am now on FFox V30, and while it starts out at about 300MB, after a few hours it grows to be typically 2.xGB.

I have run the about:memory several times, but don't know how to use the results to any advantage. It appears that about 7 tabs each use about a 1/3-GB of memory.

I typically will have 5-6 windows open, a total of 20-30 tabs.

I have seen several threads on this, but none with any resolution, and dating back to V4 (about 2006)!

Is there any hope, or way to resolve, or just need to jump to Chrome?

I often get fed up with firefox, the only reason I stay with it is because of the 3rd party plugins, but this is a step too far.

I am so seriously pissed off with Mozilla Firefox, not just because of the new design but the complete lack of respect for your users.

I got a message saying that there was an important security update, it did NOT NOT NOT warn me that it intended to install a completely redesigned application.

Have you guys heard of change control management?

I am in the middle of working and I spend 15 hours a day online, now i have to figure out this AWFUL user interface.

I guess this is what you get when you have a bunch of amateurs developing software.

So what was it, did not one person in Mozilla figure NOT out that you need to tell users that an upgrade includes a serious change in UI or worse still did you know and think FFF..orget them we will just do it and tell them it is a security update.

Rather than creating this terrible user interface you should have focused on the biggest problem with Firefox MEMORY and CPU usage with the ability of users to figure out which tab is using memory or CPU,

If I had wanted a Google Chrome clone I would have installed Google Chrome, but I hate the Chrome interface. Do you not know that Google are the worst company in the world at designing a UI, their email is rubbish, the new adwords Keyword Planner should be used in schools and colleges as a "how NOT to design software"

What pisses me off is that you have the arrogance to think that you can just bulldoze over your userbase. If I were local I would come to your office ask which bright spark was in charge of this and punch them in the face.

I have seen others ask how to roll back and again in your ignorance you make pathetic excuses and lock the question, as you did with the guy here:

https://support.mozilla.org/en-US/questions/997424

well if you do that with me I will raise this on every blog related to Firefox. I wonder if there is any interest in creating a fork in the development?

I do not want to have to install an old version, I have a lot invested in my Firefox user interface which has been completely screwed up by this update. In addition to this I can't move the address bar and put it next to the menu and I can't move the tabs below the menus and toolbars.

You have also screwed up my colorful tabs which I need because of sight issues.

THIS IS MY DESKTOP do not DICTATE how I layout my screen!!

To call you complete F'ing Morons would not be enough!

Now if I roll back I am going to be facing nagware and security risks.

In future can you PLEASE respect your users by doing the following:

1. Do NOT install UI changes without informing the user and giving them a choice 2. ALWAYS include a feature to stick with the old UI 3. Allow users to stick with the old UI and still get REAL security updates.

I am so angry with you right now!
