Long time Mozilla Firefox user with longtime Personas Plus 1.73 etc. Hadn't changed my persona for awhile, went to change today and repeatedly received error message: " This add-on could not be downloaded because of a connection failure on Addons.mozilla.org. and what happens is, you select the persona you want, then it seems ok, and tells you to add to firefox ( remember that Persona's Plus 1.73 is already on computer and totally enabled) so then you click and it looks like its happening, but then the error message appears. I have tried disabling personas plus 1.73, uninstalling it, etc, all the fixes I could find in mozilla support and elsewhere, tried that whole change the xpinstall.enabled thing but it did not work. I have windows 7 and most uptodate Mozilla firefox (main browser) and because I have so many bookmarks, favorites etc, I am unwilling ( and see no point, since all other add ons extensions themes work fine) to reset my entire firefox ( bad idea I learned in the past/hardway...) and I have sent email to personas web developer, doubt I will hear back but am hopeful someone who knows mozilla will answer with viable solutions to fix this. Note: if I sign in to personas and go to my favorites, add the theme I want then click on the personas menu from top of firefox and scroll thru my zillion favorites of themes, i can usually get it to use that favorite I chose, but this is a long drawn process and should not have to be the only way (workaround) It should be selectable from the personas screen ( yes I am signed in to see and add to favorites in personas). so with all this information can someone out there on the 'inter-web' help me ? Are others experiencing this ? I have looked everywhere for solutions but so far nothing.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.


If the issue is still there;

Start Firefox in Safe Mode {web Link} by holding down the <Shift (Mac Options) > key, and then starting Firefox. Is the problem still there?

This worked, but now the question is how do I know which item is causing this configuration problem? I don't want to stay in safe mode, but have no idea which item is causing problem, can you tell me that?

Not sure how to give update, but here it is: I discovered the problem is with the Open Tabs application by Piro. So after disengaging all the other addons I found it to be this one that was causing it. Unfortunately no work around to be able to keep using that add on so choice: 1) disable app or 2) stop trying to access persona, so for now guess I will stop trying to access persona since I really use the open tabs add on application a lot more than personas. If anyone find a way to do both, please update. Thanks

Disable the Open Tabs application. Do whatever you need to do. After, you can turn it back on.

Contact the Open Tabs support page and talk to them.

Yes, I have sent email to the Open Tabs support, not sure will hear back, hope so. I did disable and it worked, then re enabled but I guess every time I need to change persona, will have to go through those steps until some workaround or update/fix. Thanks for heads up.
