Solved Firefox plugin-container

Hi,

Recently when I use Firefox to surf on the Internet, I always have like 5-6 tabs opened. After 5-10 minutes, the browser is running very slowly and sometimes at the top bar it says (Not Responding). It is like a performance drop, changing tabs is slow, scrolling down a page is slow. I check the Task Manager it uses like 1907.23 MB of Memory and it shows 99% of Memory used.

I always have to end the Firefox process and open it again and restore my last session. It always use 150-180 MB of Memory at the first minute. But the longer I keep Firefox open, even on Minimize, my computer slows down and again it use 99% of Memory so I have to end process again. This happens over and over again. And when I check my Crash Dumps folder, I saw a lot of plugin-container dump files.

So how do I solve this issue? It's not a big deal though but I want a solution.

EDIT: Firefox is my preferred browser, I don't really like Chrome and not to mention Internet Explorer.

First, make sure you have the latest version of Firefox ie. 38.01
Next, right click on the Title, and select Menu Bar. From the Menu, click on Help->Restart With Add-Ons disabled to see if you experience the same problem.

If the problem is gone then go to Tools->Menu->Add-ons and disable all the add-ons then re-enable one by one until you experience the same problem then you might have a bad add-on.

If the the problem still persist. Tools->Options and create a SYNC account and sign-in. This will save all your Bookmarks, Add-ons etc...
then uninstall Firefox completely.

Next, download and install Firefox again then sign in to SYNC to get back all bookmarks, add-ons etc...

topguncp, there is another way to save FF's everything:
Users [user acct] Appdata Local Mozilla
Users [user acct] Appdata Roaming Mozilla
copy those two folders somewhere, ie MozillaLocal and MozillaRoaming in the Data partition.
I mention this because I have not yet been successful in creating a FF sync account, an error keeps cropping up. If said error happens to the OP, the above is an alternative.

I have 4 PC's in my home and all setup to use SYNC. If not which PC do I use to save those folders/files as you mentioned ?. If you are unable to setup SYNC then it must be something wrong at your end.

The advantage for using SYNC is all the PC's are in SYNC with Bookmarks, Add-ons etc.... If I add a bookmark in one PC, the others will be updated instantly.

Thanks for the help. So far "Restart with Add-ons Disabled" is working. No more performance drop and memory usage is good. Guess I'm gonna enable the add-ons one by one, see which one is the cause. Thank you.
