I've been using Firefox since well, lets just say long enough... Version 20 for the Mac seems to not have fixed any bugs or memory leaks.
One of the "fixes" is to restart Firefox, which is the only "fix" that works, but this really isn't a fix, this is a stopgap situation, in where you release the memory by closing it...
Are there other people with this same situation? My Firefox uses with nothing in the main page except google.com, if it's open for over 24 hours over 1GB of ram... 2 GB in 48 hours, etc...
The most Firefox has ever used was 5GB before I shut it down, now I know, restarting Firefox seems to stop this from happening, but as I said, this is a stopgap, there is something inside Firefox that makes this happen.
Is there anything in the future that will fix this issue, or is Firefox going to be forever a Memory Hog worse than Microsoft Office?
You can check the memory usage on the about:memory page.
Yes, I know about that document, as I stated above the only thing that fixes it is restarting the program, which isn't a true fix, just a stop-gap.
So, minimizing the memory usage by clicking the button on the about:memory page doesn't have effect?
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Do a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.
Download a fresh Firefox copy and save the file to the desktop.
Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
Your bookmarks and other profile data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.
To Reset Firefox do the following:
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

@cor-el the only extension I have running is Ghostery, I have my cache cleaned out every day by a chron job, and through another app I use to keep my computer running smoothly. The Cache is not allowed to 50 MB, I have no Application Cache, and as you will see via the image this version of Firefox was installed a little over a month ago.
When I installed it, it was from a clean install. I used Amnesia to remove everything, including my personal data. I have everything on the cloud that I need so getting my personal info back was no issue.
Also, a heads up, I'm on a Mac. As my More System Information shows on the right of the screen.
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_3) AppleWebKit/536.28.10 (KHTML, like Gecko) Version/6.0.3 Safari/536.28.10
This should not be happening with less than a month under the life of the App unless there is a memory leak. Restarting the App, Resetting the App, and going through the steps I have should of been more than enough to resolve this issue.
As shown above I went beyond that, no go... I did a clean install a month ago, I really don't understand why this is happening. I can wipe out Firefox again, but seriously? Are you telling me once a month I got to blow away Firefox and re-install it to keep it "fresh and functional"...
That's not a fix, as I've said before, that is the ultimate stop-gap, one I will not tolerate. Safari is looking pretty good to me right now.
Also, the last time I posted about this, and it was a real issue was back in version 4, and was beta testing version 5. At that time over 700 people said they had the same issue. Want to wait a week or so and see how many more people have the same issue?
I don't see why after 16/15 versions this issue has not been resolved.
the most common cause of memory leaks in firefox are third-party extensions. you didn't provide much information about your configuration though - please go to firefox > help > troubleshooting information & use the button to copy the contents of the page & paste them here into a forum reply...
Here you go, there is nothing in my extensions except Avast! WebRep and Ghostery, that's it. Nothing fancy, and except one, I haven't stated before.
I am not an extension collector, I only use what I require. As you can see there is nothing truly out of place.

yes, this all looks fairly normal to me - nothing that should give concerns in relation to RAM leaks. could you test if you can replicate the problem while you're in safemdoe (as explained by cor-el above) nevertehless, since it might provide some other clues... (hardware acceleration, jit-compiling and other things are turned off there)
