about:me addon causes Firefox not responding

[difabor]

It seems strange, absurdly and unbelievable, but with this addon my FF offen doesn't respond and when I disable it, the browser always responds.
This addon is very nice, brilliant and I disabled it with blood feelling and with big pain. I don't exclude, that I'm wrong, but can you by some way check my suspicion?
Thank you

Did you restart the browser after disabling it? It isn't a restartless add-on, so you would need to restart the browser. Also, the add-on shouldn't do anything unless you navigate to about:me, and even then it uses async queries, so the browser should still respond. Could you be more specific about what caused the responsiveness issues?

Thank you for respond. I'll try to describe all in details, but take into account, that I'm not advanced user and some details might be redundant. I apologize in advance (also for my English :( )

1. I used Firefox with about 100 addons and it began offen to behave strange: every 3-5 minutes Firefox stopped responding on 5 - 40 seconds and then returned to respond.
2. I disabled few addons, but this did not help.
3. Then I disabled about 80 addons and this helped, Firefox did not stop responding and memory usage decreased about twice - from 600MB in average to 250-280MB.
4. Then I gradually began to enable addons. Of course, for non restartless addons I restarted Firefox.
5. Firefox began to stop responding when I enabled "about:my" - it was enough rare and took about 2-5 seconds.
6. I disabled this addon once more and this helped. I switched it on and off several times and found the consistency - Firefox sometimes stopped responding when this addon was on and never - when off.
7. So, i disabled it and continued to enable gradually other addons and some time did not suffer from this problem. But then the strange behavior of Firefox returned and currently it relatively offen stops responding on 5 - 40 sec even with disabled "about:my"
8. So, I don't say, that only "about:my" makes this problem, but "about:my" was the first one which indicated this...
9. I'm speaking about perioud of about a week - it was not ecountered one or two times... And of cource, I restarted Firefox where I had to restart it.
   Thank you.

Well, difabor, 100 enabled add-ons are considered to be very, very, very many. From what I hear, most people have less than 10. I have 58 (at the moment) in SeaMonkey, and I thought I was way off in left field (and that most people would regard me as not quite right in the head); welcome to the club of extension lovers. I do experience some sluggishness from time to time — occasionally I can type five or six words in an outgoing email before seeing them suddenly appear — but usually it doesn't exceed my patience.

Of course some extensions are more resource-intensive than others: UserAgent Switcher sits there doing nothing until you click its button, Adblock Plus watches everything you browse, ChatZilla runs its own Internet traffic even when you aren't looking at it… Maybe you should take a hard look at the "enabled" extensions, listed at top of the list in either the Add-ons Manager or the "Help → Troubleshooting Informatoin" page, and see whether there are any that you could do without.

Thank you for detailed explanation. Of course, I'll try to clean something. I understand that this behavior is a result of several heavy addons. But "about:my" I enabled when I had about 30 enabled addons and Firefox began to "grizzle", and when I disabled it, I could add about 10 addons without problems.
Of course, I'll continue to seek most problematic addons and intend to repeat my experience once more. The "about:me" addon is relatively light weight (51 KB) and it (from my point of view) should not interfere with routine work, use many resources etc. and I was fully surprised. It looks paradoxical...
In addition it is very nice addon...

FYI: It seems that I found the most problematic addon - Feed Sidebar. I disabled it and found another one with close funcionality and so far Firefox behaves good. I enabled about:my addon.
Sorry for disturbing :(
