Incompatibilities with GroupSpeedDial add-on in Firefox

[Juraj_M]

Hello,

I'm author of GroupSpeedDial add-on for Firefox (and Chrome) used by ~50k users.

I would like to report issues with your product "Malwarebytes" reported to me by several users.

What Malwarebytes does is deleting or corrupting files that contains my add-on database "IdexedDB" (standard database API for add-ons, see https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API). Then my add-on won't load correctly and users see on the main dials page just error message mentioning corrupted database.

The files are located in:

C:\Users\PROFILE_NAME\AppData\Roaming\Mozilla\Firefox\Profiles\PROFILE_NAME\storage\default\moz-extension+++_MY_ADDON_UUID_

My add-on is using database to store thumbnails and backups. So it contains all URLs of pages that users have in their dials. Maybe some of theirs pages are detected and thus reason to block the access to that file? I'm just guessing here.

Anyway, please let me know once this is fixed, because there is nothing I can do.

Do you have any logs from Malwarebytes of this happening? That will help us figure out what's going on.

I also moved your post to a more appropriate section to help it get resolved faster

Thanks @Allessio77. Can you go to Malwarebytes -> Reports, find one of the reported blocks, and export it to a file, then upload that file? If you're having trouble finding it, you can run mb-check from https://downloads.malwarebytes.com/file/mb3_check and upload the zip file it creates on your desktop

Here is the file mb3_check produced:

mb-check-results.zip

Hello,

Can either of you provide a scan log from MBAM showing the detection? I installed your addon but am not getting any detection on my end.

Also, can you please post a screenshot of the real time protection popup so we can see what's blocking it? The only block I see happening is for cruxnow.com

Hello,

I forgot to mention one fact. The problem seems to occur during the Firefox upgrade. Allessio777 wrote me this happened twice now with last minor upgrades to 57.0.3 and 57.0.4.

I will contact also other users that had this problem to contribute with their logs.

This is the error that pops up in Group Speed dial when I upgrade in Firefox or I run Wise Disk Cleaner.

The error you see there in quotes comes strait from the IndexedDB `onerror` handler. The official API says:

Quote

UnknownError -

If the operation failed for reasons unrelated to the database itself. A failure due to disk IO errors is such an example.

Based on the bugzilla topic:

https://bugzilla.mozilla.org/show_bug.cgi?id=944918

The error can occur when unexpected files are found in the profile folder where IndexedDB is stored.

Is Malwarebytes creating any files in the folders it scans? Some hidden or "lock" files?
