I use Portable Firefox 3 with Dropbox to insure all the changes, I have made in one computer will be there in another. And I love this setup, as I do not always have to carry my Flash drive. However, I have noticed that the size of portable firefox is almost about 400 MB and increasing. When I check the folder data/profile, I found many Sqlite files, which constitute about 300 MB. Some of them are date-format ("cookies (IBM's conflicted copy 2009-04-13).sqlite").
Can I delete some of them, at least old ones? Please help me, I don't have any idea what are those files?
Those conflicts are not due to Firefox or our portable launcher itself. Most likely you used it in two locations and it couldn't sync it properly. Delete all but your current and make sure you only use one copy and then sync it back.
Sometimes, the impossible can become possible, if you're awesome!
I deleted all the files with "conflicted copy" in its name (with older dates). How to avoid this? Does it happen if I have firefox opened at two computers at the same time?
Thanks.
they are created by the Dropbox sync process. I would suggest that you look on their support forums for tips on how to avoid such things.
Unfortunately, I don't use dropbox, so I can't help more
Do you have Security - Suspected Attack site and Suspected Forgery enabled? If you do, then the urlclassifier3.sqlite file will grow quite large. Disable both those options and then delete urlclassifier3.sqlite. FF will generate a new file automagically (only 32k after that).
