I've been using Firefox 4.0b3 for a week or so now. As always when I switch to beta, I usually loose some functionality due to some extensions not being validated with the version of Firefox that I use. I've been using delicious to manage my bookmarks for the last two or three years, because it enables me to share my bookmarks (and I don't have a lot) with other computers, other browsers and with my friends (yes I'm a web social beast).
So this morning I was clearly happy to see that the delicious team had a nice extension in beta for me to try out. I was all happy about it and installed it. My bookmarks where back in place ;-) I then noticed that I had lost mouse gesture. I disabled the extension and woot mouse gesture was back. I then send a little email as a piece of feedback to the delicious mailing list.
Two hours later I was contacted on instant messaging by the Yahoo developer. And we tried to figure out what was going on. The only thing That was left was my personas theme. So I went to getpersonas.com , I then noticed that it solved my mouse gesture issue. Restarted Firefox and yet again lost gesture until I opened getpersonas.com in one of my tabs. So I have this weird bug about an extension, a theme that will work together if I load the web site where I got the extension from, I'd love to file a bug, but I have no idea, where/why/how.
I had to uninstall the Beta 4.x altogether this morning. It had bee quirky for the day that I had it in already, but last night the windows just disappeared, couldn't be brought to front or anything else. Even restarting didn't fix the problem. New windows went the same way.
