Restrict cache folder size in roaming part of the user profile

[Osdoba, Sascha]

Hi,

from time to time we see users with big data size in "%appdata%\Mozilla\Firefox\Profiles\userprofilename\storage" folder.
This is the part of the profile which is roaming (server synced user profile) and this is occurring long log on and log off time.

Is there any way to avoid that? Can I set an max size, if yes, how?

Wouldn't it be better to save every cache data in "%localappdata%"?

Regards,

Sascha

If possible, you can choose to exclude that folder from roaming, but that depends on the system management your company uses.

Hi Wim,

 

but this is complex because “userprofilname” in "%appdata%\Mozilla\Firefox\Profiles\userprofilename\storage" is never the same

on different accounts. I need something manageable in Firefox.

Hi Sascha,

Again that really depends on the system/desktop management you're using.

For Firefox we've predefined the location of the profile, by controlling the shortcut.

We added the parameter -profile %APPDATA%\Mozilla\Firefox\Profiles\<your choice of folder>.

Hi Wim,

 

i understand it and I see the value and advantage of your default settings. But its too late for us to do it that way ☹

storage is not technically cache, it's web storage;

We have a bug opened for this, but unfortunately it hasn't gotten any traction

Also FYI, there's a script in there that folks are using to solve some of this.

Hi, you can use the "dom.quotaManager.temporaryStorage.fixedLimit" pref in about:config (value is for Bytes) which will have an impact on the max size of the %appdata%\Mozilla\Firefox\Profiles\userprofilename\storage\default folder (which websites can make use of via IndexedDB and cache API). Any origin can use only 20% of the global limit, so e.g. if you set dom.quotaManager.temporaryStorage.fixedLimit to 1GB, a particular domain like google.com can use 200MB max - I think some sites like WhatsApp Web will show some breakage, if the limit is set too low...

Best regards

Hi Mike,

 

this is exact the problem we have. I added some comment there. I hope it will be fixed/changed soon because its really annoying.

I will check the script and do a testing implementation. Thanks.

When I was a running a Windows desktop network in a university
I would have been prepared to throw money at this
even though universities don't have money for software,
and my user base was 10:1 Linux:Windows.

Figure out all the other parts later if you want,
but at least get an option to take the web storage
out of the roaming profile and onto local storage;
it is difficult to see why it should ever have been in there
and it is sufficient reason for sites to default to another browser.

If you need to send a hat around do so, but this should
be the top priority for enterprise firefox IMHO.

Has Mozilla put significant resources into "Enterprise Firefox" (ESR), or is Mike the only one really working on it?

Consider there's a similar bug open for Thunderbird here:

https://bugzilla.mozilla.org/show_bug.cgi?id=517425

And a different 'script' approach (with junction).

Hi Mike,

 

it looks like also other users have the need to get this solved. May you can put that topic in the right direction?

 

Script is fine and working (but check it before apply it, also the last comment from MM) but this should be fixed

somehow in Firefox with no workaround script needed.
