873760 - Bookmarks toolbar randomly fails to open folders

Status: RESOLVED WORKSFORME

(Firefox :: Bookmarks & History, defect)

Description

[cirno]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0 (Beta/Release)
Build ID: 20130409194949

Steps to reproduce:

I'm using the bookmarks toolbar with many bookmarks and folders. My sync quota is 930KB, if that matters, and I experience this bug for quite some time now. I click on a bookmark folder.


Actual results:

The 'dropdown-menu' is transparent and I can't read the titles. I can still click and open them, though. If I deselect and open the folder a few times, it eventually shows. Each folder does not contain many entries. Sometimes a folder opens the first time after I start Firefox, sometimes not.


Expected results:

The menu should just show up properly, like it does for example in the sidebar.

I thought about it some more and I think the bug especially occurs for a folder that contains feeds. It is very random, though. Most of the time, every thing works fine. If one folder doesn't work, the others usually do. It bugs me about 1-2 times a day and doesn't go away for about 5-30 seconds of repeatedly clicking.

I was unable to reproduce this even with a folder containing lots of bookmarks and feeds.
Based on comment 1, I think this is quite difficult to track and takes a lot of time to reproduce it.

Lately it got worth, I created a new folder with only three bookmarks in it and could barely open it. Feeds didn't seem to be the actual problem. So I experimented a bit.

After exporting the bookmarks as JSON and importing them again, the 'lag' was gone.

I used the same profile for several years now, added and removed a lot of bookmarks and also used Mozilla Sync. I don't know how the bookmarks are stored, maybe they were defragmented or something.

I guess you can mark this as resolved.
