My Firefox starts to behave abnormally. Each tab I activate ‘freezes’ the CPU at more than 90% and t page is only shown after seconds… It’s becoming impossible to work.
I’ve removed McAfee SiteAdvisor recently (changed to Finjan) but I don’t think this is related with.
This is happening in XP SP2+ (+ Comodo v2) and with less intensity on Vista (+ Comodo v3 beta).
I’m quite sure some extension is doing that, but I can’t discover which one… I used them a lot of time… Maybe some newest update of any of them.
Is there a way to debug?
Is there a way to isolate the problem?

You can try running firefox in what they call safe mode, it effectively runs firefox without extensions.
There should be a link in windows Start, Programs, Mozilla Firefox, see image.
If firefox still experiences the same problem then it is probably going to more difficult to find the cause, especially if you have made any changes in the about:config settings, you could check the User Assigned values if they effect tabbed browsing settings, etc.
If it runs OK then you will have to try and detect which extension is likely to be the culprit, but I don’t see any obvious candidates in your list of extensions. So it could be a long process of pausing all extensions (in normal mode) and add one at a time until you hit the problem extension.
You could look here: http://www.mozilla.org/quality/smoketests/
but I think the troublesome extension could be FEBE here. Disable this extension, and see what happens there. On the other hand you could reinstall FF and recover your settings with FEBE in the new fresh install.
For the tab/cpu-consuming problem try to renew your profile:
Many bad Firefox behaviors are in fact caused by one of the many third-party ‘themes’, ‘extensions’ and ‘plugins’. These will go away with a new profile - that is, when Firefox is restored to default settings and without any extensions and themes.
Problems with corrupt profiles are not handled in bug reports: if your problem went away with a new profile, please do not report the problem as a bug.
Start Firefox by entering the following command is a terminal: firefox -ProfileManager. You should now see the Profile Manager window.
Important note: From the Profile Manager you are also able to remove and rename profiles. Be very careful when deleting profiles, if you created the profile in a directory that already existed, the entire directory will be removed!
Click on the ‘Create Profile…’ button to start the ‘Create Profile Wizard’. Click ‘Next’ and enter a descriptive name for the new profile. Click Finish to have Firefox create the new profile. You should now be taken back to the Profile Manager and the newly created profile should be listed. Select it and click ‘Start Firefox’. Try to reproduce the bug with this new profile.
Note: you can go back to your own profile by starting Firefox using the command firefox -ProfileManager again, selecting your own profile, and clicking on ‘Start Firefox’.
When I had a similar problem with firefox, I finally had to totally remove it from my system and
start all over again.
I know it’s a pain but sometimes a fresh install is the only way.
@Bob: I’ve done this two days ago… I just don’t want to do it again… @David: Yes, it works. This is why I’m thinking about one of the extensions… I just start to think on NoScript…
Tech had a very similar problem in the end I found it to be Gmail Skins 0.9.8/CuteMenus - Crystal SVG 1.9.1/Conflicting with one of the other themes I was using. I dont know which Theme it was as I removed them all but default. I only ever have two themes installed now.
I would also check that some of the tab settings in Addons like All-in-One Sidebar 0.7.1/Tab Mix Plus 0.3.6 are set differently. They all have different uses for tabs which are very similar and could be conflicting.
One other thing I would try would be to disable SafeDownload 1.0/ Restart Firefox as the Free Download Manager plugin 1.3 could be causing a problem with it.
I have also found that some of the extensions leave bits a pieces of themselves behind and a search in about:config locating the left-overs right clicking on the setting and select Reset. Close about:config and FF restart FF and research for the setting and you will find it has gone.
Once you have things settled remember to Close FF and delete extensions.rdf/extensions.ini/extensions.cache from your profiles folder, they are rebuilt when FF starts. hth
I’ve restored an old FEBE backup, with the same extensions in a new profile (per Polonus’ suggestions) and it’s working now on XP. Vista is acceptable… I can’t be sure that something is wrong. But I can disable that extensions to take a look. Also, I’m using the Blue Qute theme for quite a long time without problems…
These two extensions are a must have for me…
Could be… but isn’t there an option (a way) to debug Firefox without uninstalling all extensions and starting all over again?
Can you give me more explanations? I can’t follow exactly what I suppose to do…

What I have found in the past Tech is that if you remove some addons parts of the addon are left in [b]about:config[/b]
One example is "Flashgot" once this addon is un-installed it leaves 2 to 3 entries in about:config.
What I do after removing any addon is do a search in about:config for any left over entries, if any found right click on it and [b]reset[/b] all of the entries that are left.
Restart Firefox do another search of about:config and the left over entries are gone.
I then close Firefox delete "extensions.rdf"/"extensions.ini"/"extensions.cache" from the profiles folder.
Thanks Peter, but this is a new firefox installations. I haven’t uninstalled any extension on that particular profile. I did not install FlashGot, for instance. I don’t seem to have any leftovers.
I’ll try to search into Themes and not into Extensions. Maybe some glitch in the theme I’m using now.
Thank again for the support.
Just to establish whether it is Mozilla related or a problem of your OS configuration, just download Flock and install your add-ons with Febe there. When Flock does its job without further ado, then you know what is wrong.
