If gmail is open in one tab all other tabs take an extra 15 to 20 seconds or more to load (w/dsl). After closing gmail the delay persists for up to 20 seconds or so. I just noticed that gmail has the same effect on other programs like utorrent. When I opened gmail all utorrent traffic ground to a halt until I closed gmail.

Reproducible: Always

Steps to Reproduce:
1.open gmail in one tab
2.open another website that normally loads quickly in another tab
3.
Actual Results:  
Second tab is drastically delayed


It may not be a Firefox issue, but it would be nice if Firefox had a way to isolate gmail from slowing down other tabs.

Gmail is based on iframes, which can slow things a little bit. I agree with you on the fact that this might not be a Firefox issues, still, juanb what do you guys think?

I am still experiencing this issue. I have not tried safe mode. When gmail is open in one tab, it basically "owns" Firefox. If several tabs are open the gmail tab uses 100% of resources and no other tab will advance until the gmail tab is finished. Also, the gmail tab takes quite a while to up/down load information compared to other email.

I'm not having any problems now at all. (Now using Firefox 4.0)

I'm going to add something to this because it seems to be a related issue. For the last few days when I delete emails from any folder in gmail there is a long wait for gmail to respond. After sometimes 10 or 15 seconds or more I click on another bookmark to go to another website and get the pop up "This page is asking you to confirm that you want to leave - data you have entered may not be saved.
Leave Page? Stay on Page?". I click "Leave page" but nothing happens. If I then try to close the tab I again get the message "This page is asking you to confirm that you want to leave - data you have entered may not be saved.
Leave Page? Stay on Page?". (I already said I wanted to leave the page!) 

This only happens with google, and is one of a bunch of problems I've had with google in FireFox. I switched my Firewall from Zone Alarm to Online Armor about the time this issue started again, but there have been enough issues with google that I feel like something is not quite right about the connection between my computer and their website when I use Firefox.

I had this issue and other issues with google on another computer in the past using another version of Firefox.

If you can reproduce the issue in Safe Mode and with a new profile, and with all security software disabled please open a new bug report. This is not the same issue that was reported.
