Facebook and Google costing Firefox 10/10.0.1/10.0.2/11b3/11b3 to load slow
FF loads tabs slowly since v. 10.0.0 update. v. 10.0.1 and v. 10.0.2 as well as 11b3 and b4 have the same issue.
All of my tabs load slowly. On average I have 6-7 open, two of them are Facebook and Google+ which are both Pinned as Apps. It takes 3-4 minutes to load all tabs, and the browser is basically frozen doing the process.
If I close Facebook and Google+ the tabs do load a lot faster then the 3-4 minutes. But it till takes around 30 seconds to load low requirement websites.
Additional System Details

- NPRuntime Script Plug-in Library for Java(TM) Deploy
- Shockwave Flash 11.1 r102
- VLC media player Web Plugin 2.0.0-rc
- Adobe PDF Plug-In For Firefox and Netscape 10.1.2
- User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0
I have reinstalled FF10 and updates to FF11b4. Updated Java and Close both my Firewall and VPN tunnel.
I have disabled TabMixPlus, AdBlock Plus, NoScript and Do Not Track Plus.
This makes no difference.
Other add-ons are FireFTP, Lilium, AddThis, Dictionary Switcher, SearchLoad Options.
Try to uncheck this setting:
- Tools > Options > General > Startup:  Don’t load tabs until selected
Firefox does not actually reload the tabs when starting. It only opens the various sites in different tabs to confirm that they are still available. TMP prevents tab reload so that you have the same page in front of you as you did when you closed down Firefox, like when twitter updates your timeline, the tweets displayed when I open FF again, are the same as those hours before.
So it is not the reload, TMP disables that function.
Update. It is NoScript which is costing the issue. Not that I have changed anything or configured it in any way. But at least I now know that much.
Now on to finding what function is the actually generating the problem.
