Firefox memory leak causing slow and stuttery performance

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?

Yes like I said I have already tried everything I've read online which includes:

  • 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!)
  • Disabling all add-ons and extensions

and so far none have worked

Try out Firefox ESR release, it might help you. http://www.mozilla.org/en-US/firefox/organizations/all/

How will the ESR release help me with memory leaks?

This is a stable release especially for companies.

I see, the version for the ESR release is pretty outdated however and this feels more like a workaround than a fix.

Have any definite fixes been established for the memory leak, so that I can run the latest version of firefox with no problems?

Do you use many tab simultaneously?
