firefox running out of disk space

[alvaro991]

hello i use firefox 64 portable. FF64 and working on disk z: and forder il 20gb my forlder for download is d:\download and space is 1TB

a) when ff64 start normal donwload he create temp file on d:\download and when finish download create final file always on d:\download

b)the MDM start download and he create temp file on: z:\FirefoxPortable\Data\profile\storage\default and when temp file active is up 5gb the FF64 send message "firefox running out of disk space" and download stop. The MDM not change path for temp download and this very big problem. I can not change the path of the whole profile.

And I do not understand why when the sum of downloads in the queue exceeds 5gb the warning appears even if I have 20 free gb

1. I ask you if you can allow the change of the file path temp download, and change path for final download.
2. eliminate the alarm "firefox running out of disk space" when temp file sum is up to 5gb

thanks

Firefox has limits on its internal storage (temporary download), and extensions cannot write more data if 50% of free disk space is used. In my test on a 2GB virtual drive, the extension cannot download any more when the free space decreased to about 800MB.

Until more APIs such as Writable Files arrives, I do not know any way to avoid the internal storage.

It is possible to move the internal storage of this extension to a different folder/drive using symbolic links.

1. Exit Firefox;
2. Locate the storage folder:

Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++12345678-1234-1234-1234-123456789012\idb\3109085620fsiel.files

In the latest version, the folder name should end with fsiel.files. The moz-extension ID is a random UUID, that can be found in about:debugging under this extension's name. There will also be tsaks.files and ect.files, which stores some metadata and configurations.

3. Move the directory to another drive, e.g. E:\3109085620fsiel.files
4. Create a symbolic link back. Open cmd with administrator privilege and run:

mklink /d <original location> <moved location>

e.g.

mklink /d Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++12345678-1234-1234-1234-123456789012\idb\3109085620fsiel.files E:\3109085620fsiel.files

The symbolic link will show in the original location and has the same content as E:\3109085620fsiel.files.

5. Start Firefox and see if it works.

thanks i have create link: mklink /d Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files d:\3109085620fsiel.files symbolic link created for Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files <<===>> d:\3109085620fsiel.files

permission working: full controll

start FF64 select download and mdm capure download but not start and generate error: "cannot access internal storage"

I'm not sure what is happening. I've tested again with Firefox 64.0 Portable on virtual drive Z:, and the symbolic link work.

Could you try whether the link works in Windows Exploerer? Clicking the link in the profile in Z: should show the content of the corresponding folder in D:.

Also, try debugging this extension in about:debugging (check "enable add-on debugging" and click "Debug"). Check the "Console" tab and see if there is error messages.

my sequence:

join on Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb and rename: 3109085620fsiel.files to 3109085620fsiel.files2

join on d: and create 3109085620fsiel.files

mklink /d Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files d:\3109085620fsiel.files

copy file on: 3109085620fsiel.files2 in to d:\3109085620fsiel.files

write example file test.txt on d:\3109085620fsiel.files and this new file show on: Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files

delete file: Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files\test.txt and file test.txt "auto delete" on d:\3109085620fsiel.files

The 3109085620fsiel.files2 folder has to be removed, otherwise Firefox will fail to access the storage (4th note in this doc).

However, with more testing I found that Firefox still shows the out-of-space error after moving the storage folder. It seems that the quota is still enforced according to the original drive. I'll see if there is any other workaround.

find solutions: mdm required recreate total file of idb

join on Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9
and delete total file and folder

cmd and command: mklink /d Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\ d:\download\idb

now create: d:\download\idb
(this step only after create symbolic link otherwise it will not work)

start FF64 and MDM not show "cannot access internal storage"

now mdm re-create total file on d:\download\idb and working

if I repeat this procedure only with the folder: mklink /d Z:\FirefoxPortable\Data\profile\storage\default\moz-extension+++502d9f1b-4d49-402d-998a-703f090d1cd9\idb\3109085620fsiel.files d:\download\3109085620fsiel.files NOT working

another problem = but now is ff64 and not mdm now symbolic link working and path have 500gb free space but FF verify free space on Z and not on D

example: z:\firefox free space 10gb

d:\download\idb free space 500gb

mdm store temp file and download on d:\download\idm.....

but firefox check free space on z:\firefox and not check space on d:\download\idb and when many download store 5gb the firefox send message: "firefox is running out of disk space, website contents may not display properly......" and firefox stop download of mdm

this problem eliminates all the work done to move the mdm path. everything was useless

[jingyu9575]

Yes I also found this during later tests. I'll see if there is any other workaround.
