That message is displayed endlessly after using Gmail, logging out, closing the tab, then opening a new tab.
Solved! Go to Solution.
I found if I disabled the drag / drop / upload extension that the issue went away -- though I had to disable it twice and restart twice for whatever reasons ... but now the issue is gone.
I did have to position my cursor over the left-top Firefox menu and then click Enter a few times to get the extensions / add-ons area open ... and then I had to do similar maneuvering when the area was open.
I had to uninstall dragdropupload because no matter how many times I tried to disable it, it wouldn't disable. Getting rid of dragdropupload did solve the problem, so thank you to all that suggested that solution.
I would have never associated this problem with dragdropupload, so how did you ever figure that out?
It was an endless loop that would not close and I couldn't click on anything else. So I had to close out firefox through the TaskManager "End Process". It was solved by disabling the firefox addon Dragdropupload.
●All those that are reporting here about Dragdropupload as the problem need to inform this to the webdeveloper in the reviews:
There is no drag & drop extension to disable! Can't say it was not helpful in that 30 others experienced the same dead object but none of the drag/drop/upload tools are listed in the browser.... So now wot?
Update: Okay, [whew] after a few hours of hit n miss, we found that 'resetting'/'restarting' Firefox with add-ons disabled was not very useful as the list of extensive add-ons required extensive reinsertion after we found the real problem was UP DATING PLUGINS! There were 2 issues with Java and an old Shockwave which required newer versions. So it seems the real solution is to break down and force yerself to accept 'Help' from the toolbar > 'Firefox Help' > enter 'Dead Object' [Search Mozilla Support] to bring yerself back to this page or merely look to the right lower side of the page for more info of CHECK YER PLUGINs! It was a challenge with restarts & discovery of the need to update but it would have been much easier than having to research, find, reorder & install the extensive list of extra special custom add-ons, extensions, theme & plugins provided by Mozilla Firefox again! It is amazing how much FoxFlags, FoxClox, Autofills, Animated AlienFoxWare & Bookmark Bar adds to efficiencies & smooth enjoyment. Tanx Mozilla Firefox!
Not really sure why but I ended up disabling my Fire Gestures (Tools -> Add-ons), restarting, and then enabling it back on and restarting again.
It's been working so far. Keep it in mind and hope this helps.
