Firefox eating memory during regular browsing all the time

For the past several weeks I'm becoming increasingly aware of severe memory issues when using FF (currently FF30 32bit). No matter what I do, FF seems to keep allocating more memory to the point where it starts having severe issues and slowdowns, eventually crashing when the used memory reaches about 2.4GB, according to Windows Task manager (I'm running Win7 64 on 8GB of RAM). Currently, the whole process got so bad that it only takes several hours for FF to crash. I don't even have to use FF for this to happen - if I simply leave it running for two hours, when I come back, it's process is already using a few hundred MB of memory more.
I've tried disabling all of the add-ons. I've tried disabling all of the plugins, including Flash (which is always udated to latest version). I've tried the safe mode. I've even tried a clean profile. Nothing really changes much - some of my add-ons might have some influence on how fast FF eats the RAM and they certainly have visible impact on how much memory is used from the start, but even without any add-ons, the memory footprint of FF still gets bigger and bigger over time just by regular browsing.
I've also tried both installing FF28 with clean profile into clean directory - again, the same behaviour was observed, although it used less memory by default and its memory footprint was getting bigger slower than with FF30. I've also tried current nightlies (FF33a1), both 32bit and 64bit, again with a clean profile, installed into a separate new folder. Again, didn't really solve anything.
I also have a second separate Windows 8 install on my PC, so I've tried FF30 in this install as well, however, it behaves exactly the same. FF does this even under my Linux installation, so I really doubt it has something to do with my Win install.
Note that I've also tried running current Pale Moon, and while its allocated memory grows much slower than with FF, it still grows over time unexplicably, and as Pale Moon is based on FF code, I'd say this suggests there's some kind of issue there.
Also note that I usually have quite a few tabs open (around 50 is my average - and no, I don't want to use less tabs, before someone suggests that, I think any browser on current hardware should be able to handle 50 tabs without much issues, and pretty much any other browser is), but the same behaviour was observed even with under 10 tabs. I also always disable the delayed tab loading, meaning that all of my tabs load at browser startup, not just after I click on them, so my starting memory footprint with all of my tabs and add-ons is around 1.4GB (1.1 in Pale Moon), which probably means I'm seeing this issue manifest faster than many other would. I'm fine with the memory it eats at startup and with the slower startup. I would even be fine with my browser taking up 2 gigs of RAM (I've got 8GB of RAM for a reason), as long as it doesn't keep on allocating more and more memory without it ever going back down, even when I close several tabs.
Finally, it might be interesting to note that the memory measurements at about:memory grow much slower than the allocated memory reported by Task manager - meaning that quite often, FF memory measurement says it's using 1395MB RAM, while in Windows Taks manager, the Firefox32 process is reported as already taking up e.g. 1.8-2.0GB of RAM, and around 1500MB RAM in FF can equal to 2.2-2.4GB in Task Manager (meaning it's pretty close to FF crashing). And the "Free memory" buttons in about:memory seem to have no effect on the allocated memory, reported in Task manager (even though they do have some minor effect on used memory reported by FF itself there).
I don't really expect much help, I think I've already tried pretty much everything there was to try and for the time being it seems to me using Pale Moon is my only option right now, as in it the memory issues are at least somehow manageable and not as annoying as in classic FF, but I still thought I might post this here, if perhaps only for someone to take notice.

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.

Hello,
Everything was running completely fine in Firefox and then all of a sudden it simply stopped displaying .swf files. Where they should be is simply blank. On websites with a background I can see the background through where the .swf file should be. This includes opening locally saved files as well as every website with a .swf file that's supposed to play.
I do mean suddenly quite literally, as it was right in the middle of a browsing session. I changed nothing, just...one minute they were working fine, the next they completely halted. It's clear the program is recognizing that something's supposed to be there, as Adblock pops up a little "Block" tab over where the file should be, but again, that space is completely blank. It's not black, it's transparent.
I've completely uninstalled Shockwave and reinstalled it from scratch, and "updated" it three times now, all to no effect.

Under Tools > Options > General, my Firefox home page is set to: https://www.google.com/. When I open a new tab, the page opens up to the old Firefox Start/Google home page.

I have the latest version of Firefox. Why aren't my tabs opening up as my initial home page opens up to: https://www.google.com/? I was looking to add a screenshot of my home page and the tabs home page, but I don't see an option to do that.

Does the Network Monitoring component of the Firefox Developer Tools have a way to preserve its log upon navigation (which would otherwise be cleared), similar to the Chrome or Safari Developer Tools "Preserve log upon navigation" button?
I've tried checking the "Enable persistent logs" option for the Web Console in settings, but it does not appear to affect the Network Monitoring tab. I also didn't see any bugs filed for it, so I just wanted to make sure I wasn't overlooking something obvious.

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.

I just checked task manager, since my computer was running a bit slow, and found firefox to be using nearly 1.2 GIGABYTES of RAM, with only 4 tabs open + Chatzilla for IRC. I have Skyrim running at the same time, and it is using LESS RAM than Firefox is!
I've tried disabling plugins, to the point where I only have the Flash and Adobe PDF ones running, I had to disable the plugin container since it crashes repeatedly (Usually at least once every couple of days). I tried using the "Free Memory" options in about:memory, and they do literally nothing to reduce the RAM usage. It's normally between 400 and 600 MB (Which is still insanely excessive for a browser). Closing Chatzilla only reduces the RAM usage by about 10-15 MB, so it doesn't seem to be the problem.
How in the name of all that's sacred is a browser using more RAM than a modded version of Skyrim?

FF uses 100+ CPU on my otherwise totally fast up-to-date MacBook. This, despite doing all the fixes suggested, repeatedly.
It has gotten so bad that it constantly overheats my Mac, causes my fan to go on full blast non-stop, even when it's in the background, so I basically have to stop using it.
Mozilla needs to get serious and overhaul this heavy-use browser.

I have seen this question already posed in the forums about updating the latest version of Firefox, however I am not trying to update the version, I am trying to download the latest version of Firefox to Windows through Chrome. I click the download button on the Mozilla website and I extract the file. At this point the computer asks me if I want to save the file or run the file. I have tried to just run the file and the computer shoots out this message "You may not have the necessary permissions to use all the features of the program you are about to run. You may run this program as a different user or continue to run the program as the currant user". The window gives me two options, "Run as currant user" (which closes everything when I choose it), and "Run as administrator" (which leaves me with a user name and password which are always wrong). I can't download Firefox and have tried alot of stuff. I feel like it is a security setting in my computer that needs to be adjusted but I don't know enough to start randomly tinkering around.
As in all Forums... PLEASE HELP!!!!!!!!

Hi,
My problem "was" that I was working on Firefox at my home and at my office. As computers are fast these days, I am in habit of opening large number of tabs in firefox. And I always wanted to open the same tabs at my office which I was opening at my home and vice versa. I further wanted to clean the browsing history after leaving the computer at my work as well as home.
While searching through the forums, I reached to this thread:
https://support.mozilla.org/en-US/questions/960096
And to my satisfaction, the exact answer was not there.
Anyways, doing a little more search, I found why I will never stop loving Firefox and its because of its wonderful "addons".
So here I re-write the problem,
I want to save the addresses of different tabs opened in my Firefox and save them to a file that can be re-opened by Firefox on the same computer or on a different computer with the option to clean the browser history after leaving the computer.
Solution: "Session Manager Addon" of firefox.
Steps to the solution:
1. Download and install a firefox addon called "session manager".
URL: https://addons.mozilla.org/en-US/firefox/addon/session-manager/
2. After installing this addon, go to Firefox -> Sesion Manager -> Session Manager -> Session Manager Options. (or to Tools -> Session Manager -> Session Manager -> Session Manager Options)
Go to "Advanced" tab.
Now change the default location for saving the session. Say you name it to your desktop.
Now, you have "Session Manager" addon installed, the default location of saving the session file is known to you (say your desktop).
3. Now go to, "Firefox -> Session Manager -> Session Manager -> Save Session" and give your session a name under the option "Save the current session as". (or to "Tools -> Session Manager -> Session Manager -> Save Session")
4. Suppose you give your session a name called "New Session". In your default location of saving the session (say your desktop), you will get a file named "New Session.session"
5. Now this file is the key. It's a small file and you can simply email it to yourself or carry it to your work with you.
6. Just place this file at same location on the different computer and repeat Steps 1 and 2.
7. Now Session Manager is installed and configured on the other computer and the file has been copied to the desktop of this other computer.
8. Go to Firefox -> Session Manager -> Session Manager -> Load Session (or to Tools -> Session Manager -> Session Manager -> Load Session) and the saved session will be loaded to the different computer by Firefox.
Now, how this addon can help someone?
1. It is extremely useful for people like me who are addicted to opening many many tabs at once and want to resume working from the same set of tabs whether they are at home, office or some other place.
2. Suppose, you are surfing some personal sites that you do not want other people to know and you can't bookmark those sites. You are on a different computer, say at your office and want to clean the browsing history too.
The best option in such cases is to save the session completely and re-load it on a different computer.
I personally found "Session Manager" addon better than "copy urls expert".
The only improvement I would like to see is that Firefox itself should allow multiple tabs to saved to a file that can be opened by Firefox just like we open a saved HTML page.
And thanks to Michael Kraft for creating this wonderful addon... Really liked and I hope my post help others.
thanks

Hi, I'm hoping someone can advise me as to why the lastest version of Firefox is not working properly and if it can be fixed. I am not tech savvy, sorry. Since the last automatic update Firefox has been incredibly slow loading pages, won't load some at all and has problems showing pictures and video. Trying to type something into Google search is nearly impossible, it just doesn't respond when I click on something or if it does it takes ages to open in the new tab. I have tried to search online for an answer or solution but can't find anything that doesn't refer to problems with Firefox in late 2017. There have been new versions of Firefox since then which claim to have fixed any bugs. I have downloaded the lastest version which I think is 58.0.1 Firefox tells me I'm running the lastest version so what can I do to fix this?
