Problems with drag-n-drop after some time in PM28

[alancast]

When I just upgraded PM to 28, it didn't work properly, so I thought a lot of addons became incompatible.

Then I found that if I turn on or off any addon and restart, PM28 works well again.

But after some time drag-&-drop stops working.
In particular, Super Drag stops working, and tabs become not draggable. Even if I disable TabMixPlus.

I still try to find which of the addons may be responsible (Update Scanner maybe?), but maybe the problem is not in addons but rather in memory use or something?

Any ideas?

I'm tired to change addons and restart every time to restore drag&drop functionality.

Besides, after I reinstalled MinimizeToTray Revived, minimizing to tray stopped working at all, any version I tried.
Which is strange, because before reinstalling the same version was working.

Have you tried making a new profile?

Have you tried making a new profile?

I tried Palemoon Portable 28 (almost without addons), and it seems it doesn't have such problem. (Though I didn't use it much).

The problem I mentioned often happens after I scan pages with Update Scanner, and then I watch a new page with diff's.

It's made by placing some big amount of info into the address bar - like:

chrome://updatescan/content/diffPage.xul?...

or

data:text/html...

So can it be that placing a large chunk of info into the address bar somehow hinders further work of the browser?

Earlier, it led to almost freezing (in Firefox too), but perhaps not in recent versions.
