What causes memory leaks?
I have had continued memory leaks, with firefox 29.0.1
I tried updating all extensions and plug-ins, I have tried making a new profile, this gave a base print of 90 MB, with only the addon tab, when i opend firefox this climbed to 190MB
my ram will usually spike within an hour of usage slowly climbing up from 255 MB (with 4 webpages) to up to 2000 MB at the moment I am running FF29 without shockwave and although the memory still spikes up to 385MB it seems to stabilize at that amount. with it only going up and down 30 MB when facebook updates. (running for 4 hours straight with no crashes or memory spikes) however like this I am unable to run shockwave content so I would like a solution to this problem. how can I watch shockwave content without the memory leak reapearing?
EDIT: it appears that if I watch videos on youtube the memory usage will still leak. (as if the content of the tab is saved somewhere after the tab is closed causing the memory to remain occupied) after watching 2 videos and closing the tab, the memory has stabilized at 460MB
EDIT: just visited kickass torrents, and my memory usage was spiked again by 30MB permanently, even after closing the tab again

Alot of things cause memory leaks, from addons, to webpages that may have a bug in them.
Could you post the non-personal troubleshooting information?
Please do the following:
- For Firefox versions previous to 29.0: Click the Firefox button at the top left, then click the Help menu and select Troubleshooting Information from the submenu. If you don't have a Firefox button, click the Help menu at the top and select Troubleshooting Information from the menu.
- For Firefox 29.0 and above: Click the menu button
, click help 
and select Troubleshooting Information.
Now, a new tab containing your troubleshooting information should open.
- At the top of the page, you should see a button that says "Copy text to clipboard". Click it.
- Now, go back to your forum post and click inside the reply box. Press Ctrl+V to paste all the information you copied into the forum post.
If you need further information about the Troubleshooting information page, please read the article Use the Troubleshooting Information page to help fix Firefox issues.
You can also try Firefox Safe Mode to see if hardware acceleration or a addon is causing a leak.
Thanks in advance for your help!

it looks like user.js is currently active in Firefox. The user.js file is only present if you or other software has created this file and normally it wouldn't be there.
You can delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release. You can get to the profile folder below:
- Help > Troubleshooting Information > Profile Directory > Show Folder
or
- Go to about:support and click Show Folder next to Profile Directory.
I have deleted them, should i now wait and see?
memory still leaks, the fastest way to check that i use is to check the memory usage before testing (370 MB with 5 pages in 2 windows) then go to youtube, watch a movie , then close the tab and check the memory again (425MB)
Did you ever try safe mode as I suggested at the end of my first response?
Note adblock plus can cause memory leaks in some pages and you can indivually disable it on such pages.
- Adblock button => Disable on (site goes here, example support.mozilla.org
not yet, I will try that next
in safe mode the problem still occures, started with a baseprint of 246MB and I am now at 348MB just from opening and closing a couple of news feed sites.
might this be related to how FF is able to reopen closed tabs?
