Delete Firefox bookmark backups to save space Web Browsers
Firefox stores backup copies of prior bookmark files, and these files can accumulate, taking up a fair amount of space. I found 129 files, the most recent being 300 KB. Deleting all the backup files saved about 40 MB in disk space.

These files are stored in your user's /Library/Application Support/Firefox/Profiles/bookmarkbackups folder. Delete the ones you don't need and you may save a lot of space.

Delete Firefox bookmark backups to save space
Authored by: pub3abn on Apr 26, '06 07:57:27AM

In my case they were in ~/Library/Application Support/Firefox/Profiles/xxxxxxxx.default/bookmarkbackups (where xxxxxxxx is an apparently random string of characters).

It seems a little annoying that they would be making endless backups (although I had only six or so, probably because I am only an occasional Firefox user). Hopefully an option to clear these out will be added to OnyX or Cache Out X or some other maintenance app. (I am quite fond of the Windows app CCleaner, and hope that one of these OS X apps will pick up some of its functionality for dealing with third party junk.)

If you find yourself needing to save 40MB, you have serious system maintenance problems. 40MB is a twentieth of a percent of a typical 80GB hard drive.

a similar problem is due to spotlight indexing the profile folder, resulting in numerous bookmarks-n.html generated files. disabling indexing of the folder fixes the problem.

this kb article gives the details.

Delete Firefox bookmark backups to save space

Curious, I went to check my own folder. I see only 6 files, as if it's only keeping backups of the last 5 times I ran Firefox, plus today.

It may be that the BookMarks Synchronizer extension is affecting this. I noticed, after starting and quitting Firefox, that the backups in this folder didn't change, not even after a 2nd start/quit, when I used the BS extension to download & upload my bookmarks. I'm sure they synchronized, but the files in this folder didn't change. Hmm.

Oh well. Not sure why my Firefox only keeps the last 5 or 6 bookmarks, but I'm OK with it.

I'm not so worried about my 5 backup files -- but why do I have *95* bookmark files, i.e. bookmarks-x.html, where x is a number between 1 and 95?

Interestinly, I had a huge number of cached bookmark files, going back to the earliest version of Firefox. A side benefit I immediately noticed is that Firefox now launches like when it was first installed. It's launch time had slowed significantly, and I assume it's because of how firefox read the files. In any case, launch times are on par with Safari again.

I've been aware of this bizarre behavior for some time. I'm a super-heavy Firefox user, my 'bookmarks.html' item is now running 2.8 MB, there are currently over 200 of these numbered backup-items, and the folder is running over 500 MB. Time to clean it out again...

OS X itself is jammed with many GB of stuff which most people will never ever touch, and experienced users may wish to dump. For example, if you never use "GarageBand", you can hunt down its massive support-files and delete them. Another huge space-waster are the Keynote and Pages apps, which you can delete if you're never going to use them (note that you must pay full price for them online to activate these apps!) Another fun one is iDVD; if you're never going to author your own DVDs, you can dump the "Themes" which are currently running almost 2 GB. Last but not least is Audio / Apple Loops / Apple / iLife Sound Effects which is at 1.4 GB.

Yes its true that we're wading around in lots of disc-space these days, but when we do our periodic full-backups -- which you're faithfully doing, aren't you? -- why not pare down their size and execution-time.

Got successful rid of this folder!
Authored by: ratzfatz on Apr 27, '06 06:09:30AM

I replaced the folder with a bogus 5k text-file - named "bookmarkbackups" and set the "protected" flag in the file information dialog. Worked.

You can also set up an Automator Workflow to delete file(s)/folder(s) which recur with the same name(s) in the same path. Such Workflow, when saved in your Library/Workflows/Applications/Finder becomes available through the Automator contextual menu in the Finder. You can use, for example, 'Delete Items' found in Delete Files.action at: http://homepage.mac.com/jrmiddle/Scripts/

It's better to set 'browser.bookmarks.max_backups' option in about:config page to 0. Firefox won't backup bookmarks anymore after this.
