    Re: Firefox optimization and troubleshooting thread

    Great thread! When I first started testing firefox 3.5 using an alpha version of Jaunty (3 maybe 2) it seemed much faster. It seems something happened to Jaunty that slowed it down. I did not add or change firefox. Did anyone else get the same impression?

    Re: Firefox optimization and troubleshooting thread

    I've been having an issue with firefox reverting to backed up bookmarks on close, I wasn't able to find a profiles folder (I assume all this is in .mozilla right?), but I did find many files labled as such: places.sqlite-#.corrupt, and there were 83 of them numbered 1-83 in the folder .mozilla/firefox/kmhbvuwv.default . I also saw a filed called profiles.ini sitting in .mozilla/firefox but other than that no profiles folder.

    I deleted all the .corrupt places.sqlite files that I found, but all that happened was the icons next to all my bookmarks were lost, and still reverted back to the backup

    The profile folder is .mozilla/firefox/kmhbvuwv.default

    Delete all places.sqlite-#.corrupt just in case, but the one that is important is the places.sqlite without #.corrupt in the name. Just delete it and start Firefox again. It should fix the problem.

    The file profiles.ini has nothing to do with your problem. It is the file that lists all profiles you have, but I think you have just one. Anyway, don't delete it.

    Ah, I see. Anyway, I deleted places.sqlite about 3 times now, created a new bookmark, then closed and reopened and my bookmark has yet to make it through the restart. I've noticed that my history disappears every time I delete it, but my bookmarks still revert. Would deleting the cached .json file that I restored from do anything?

    I think I solved it, I mv'ed my .mozilla folder to .mozillabak and then restored my bookmarks from the recent backup and then added a few new ones. Everything has persisted, even through a full system startup.

    Weird...but solved. What does places.sqlite do?

    Just for the record, you could have moved/renamed/deleted only the firefox folder inside .mozilla and the effect would be the same. All Mozilla applications, like Thunderbird or Sunbird, stores their profiles inside .mozilla, so deleting/moving the entire .mozilla folder is not recommended/needed, because it would reset all Mozilla program settings, not only Firefox.

    The places.sqlite file is a database where bookmarks and browsing history are stored.

    Re: Firefox optimization and troubleshooting thread

    For the "Font too small.." problem (issue on big Plasmas and projectors typically), I recommend the "NoSquint" addon, with it set to apply a 20% increase on all pages (NoSquint's default mode is to remember specific pages).
    http://urandom.ca/nosquint/

    This is better than changing the font size as it scales the whole page (images too), making it less likely to have overlapping or truncated text.



    Now, if anyone could advise how to get Backspace working as a "Back" button like on other platform FF builds, I would be happy.

    The "general system optimization" tips section in there is completely superfluous. It also happens to be full of misinformation, I'd just remove it or splice it out to another thread if I were you.
