Als jouw Firefox, net als de mijne, grote hoeveelheden I/O doet bij het sluiten en traag is bij het gebruiken van de awesomebar, probeer dan het volgende (eerst Firefox volledig sluiten):

for f in ~/.mozilla/firefox/*/*.sqlite; do sqlite3 $f 'VACUUM;'; done

Het is onschadelijk, er zal geen data verloren gaan: het compacteert je SQLite databases. Merkbare verschillen hier.

Perfect! een wereld van verschil.

Big thanks. Seems to work.

Just noticed: I set history to 10 days about a month ago because awsomebar was soooo slow but it still keeps all my history in the database.

For OS X, this is:

for f in ~/Library/Application Support/Firefox/Profiles/*/*.sqlite; do sqlite3 "$f" 'VACUUM;'; done

You can do this on OSX:

cd ~/Library/Application Support/Firefox/Profiles/
for f in */*.sqlite; do sqlite3 $f 'VACUUM;'; done

Maybe a bug should be filed to ask Mozilla to set the database(s) to auto-vacuum, or maybe this should be done on shutdown at least.

Thanks a lot, my awesomebar is really quickier now!

Yeah! tip of the year!!! :-)

Finally Firefox starts and stops in reasonable times!

Thanks a lot!

It is also useful for liferea, for sqlite files in ~/.liferea-1.4/mozilla/liferea/ . Thanks!

This is the problem with using SQLite in desktop apps - I need to be my own frickin' DBA!

Finally - I have a responsive Firefox again. Thanks!

didn't work for me on Ubuntu 8.10. I get a string of:
Unable to open database "~/.mozilla/firefox/432n677u.default": unable to open database file. Same thing when I sudo su to log in as root and run it.

@usar: Double check that you used the right command, looks like there's a piece of the matching pattern missing.

Awesomestest! Thank you.

SQL error: constraint failed

A general purpose shell gotcha safe version that will do all your sqlite files:

find ~ -name '*.sqlite' -exec sqlite3 '{}' 'VACUUM;' ;

Works on directories containing spaces and is safe fro cronjob use.

What about windows? How do we get a command line for Mysql lite??

How do I do that on Windows? I too want my Firefox not freeze when using the not-so-awesomebar.

@rys, @Artem: Unfortunately, I don't have a windows computer (I'm a pure Linux user), so I can't help you out there. If someone does know how to do it: let us know!

Nice! This helped a lot!
Thanks

@Aquarion,Dav Glass: Thnx! Unfortunately you forgot escaping the spaces, so the working commands are:

for f in ~/Library/Application Support/Firefox/Profiles/*/*.sqlite; do sqlite3 "$f" 'VACUUM;'; done

and

cd ~/Library/Application Support/Firefox/Profiles/
for f in */*.sqlite; do sqlite3 $f 'VACUUM;'; done

@Richard Rebel: Nice tip, there are indeed other applications who suffer from this. On OS X Tiger, example number 1 being Apple Mail..

@Tom: Unfortunately, you forgot quoting as well: Application Support contains a space, which won't work. So substitute it for Application\ Support.

I couldn't get
find ~ -name '*.sqlite' -exec sqlite3 '{}' 'VACUUM;' ;

to run, so I had to add a backslash ( '\' ) to the last semicolon ( ';' ):
find ~ -name '*.sqlite' -exec sqlite3 '{}' 'VACUUM;' ;

Nice tip, though; thanks!

Bummer, I did copy-paste the wrong snippet! Thnx for correcting my corrections ;-)

@Richard Rebel

The problem is running from a cronjob is that you probably want to make sure the appropriate applications are closed first.

It would also help speed up the new summaries in evolution I think.

Also I believe this is on Mozilla's ToDo list but they had issues with doing it automatically that are yet to be resolved.

Holy Jesus! That was one hell of an improvement! Thanks!

Not a complete windows HOWTO but this will get you there:

1) Download the Precompiled Binaries For Windows http://www.sqlite.org/download.html.

2) I extracted the file to C:bin.

3) Change into the directory containing the .sqlite files. Example: cd C:Documents and SettingsrootApplication DateMozillaFirefoxl89ueo7d.default

4) Get a before shot: dir *.sqlite

5) Run the VACUUM: for %f in (*.sqlite) do C:binsqlite3.exe %f "VACUUM;"

6) Get an after shot: dir *sqlite

For windows:
* get sqlite3 from here:
* http://www.sqlite.org/sqlite-3_6_7.zip
* http://www.sqlite.org/sqlitedll-3_6_7.zip
* unzip them both into c:windowssystem32
* cd to your profile directory (there may be an easier way to specify this from the commandline, but I don't know cmd globbing that well)
* for %f in (*sqlite) do sqlite3 %f "VACUUM;"
* note: quotes instead of apostrophes

On Windows you'll probably have to install sqlite3 (http://www.sqlite.org/download.html)

Then (Assuming that the binary is in your Windows path) you can change to the Mozilla Profile directory

C:Documents and Settings<Your Windows Username>Application DataMozillaFirefoxProfiles<random digits>.default/

and run:

sqlite3 places.sqlite "VACUUM;"

Replacing places.sqlite with the file you want to compact - sorry I'm not familiar enough with Windows scripting to work out how to automatically do it for every file - for me the only large sqlite files were:
- places.sqlite
- urlclassifier2.sqlite

To Richard Rebel:

About adding it to a cron job, Should script check if any firefox instance is running? Would it break "something" if it's run while firefox is running?

Thanks for information

sqlite has correct locking and database semantics, so you should be able to do this with firefox running.

OK, thanks for the info :-)

There should be an addon that does this once a month or so, as a stopgap before it's added into Firefox (or Gecko) proper.

WOW, thanks for this tip!

@Jeremy

Not sure about sqlite having correct locking and database semantics, but you definitely get an error if Firefox is running: "SQL error: database is locked".

Got that on both Linux and Mac OS X.

Marius: Jeremy's tip about it running this command with Firefox running still is sorta valid; it won't optimize Firefox's databases, but it won't harm them either.

So if you're setting up a cron job, it will do its thing on whichever databases are available. It's not the kind of thing you'd need to run every day, so just make sure you have Firefox (or your other apps) closed at least sometimes. ;)

Also, this wouldn't pick up any sqlite databases that don't end in ".sqlite", so there could be further gains to be made here. For example, I ran this on Banshee's database (~/.config/banshee-1/banshee.db) and found a decent performance gain in the application.
