You can attach a screenshot here in your next post, if you want.

We're interested but you're going to have to help us. We're just a bunch of volunteers here balancing our busy lives while providing Firefox support. Since you already have all the addons installed, it will much easier for you to figure out which is causing this glitch.

That is no easy task for us. So you're going to need to find out exactly which addon is causing this problem if you want to be fair about this and give the addon author a decent chance at fixing this.

Since you have so many addons, I'd recommend disabling at least 5 addons at a time, restarting Firefox then check "View" to see if the glitch has disappeared. If it has, then you'll need to concentrate your focus on individually enabling & disabling those 5 addons until you see the glitch return. Then you know which addon to blame. I bet it's Menu Icons Plus or Personal Menu.

Thanks for a second opinion, that's also what I had thought, so I'll try out that route, thanks for your fast, thorouh and kind reply. Wonder if the makers of the responsible Add-on then would like to know about it, I'll try by asking them if I can make out that particular one Add-on.

The question has been answered to my satisfaction, I'm grateful.

Kind regards

This is me again, I have isolated the add-on causing the visual glitch, like you already guessed it is Menu Icons Plus 3.1. I'll try updating it and if that won't help maybe I can contact the developer somehow. It would be a loss to lose all those nice symbols and get blank (context) menus again. And thanks again.

Awesome! Nice work man!

I did find a way to contact the author. In one of the reviews he posted this: You can contact me through http://www.codedawn.com/contact.php

https://addons.mozilla.org/en-US/firefox/addon/menu-icons-plus/reviews/623602/

Also I'm wondering what theme you have installed. It might be conflicting with the Menu Icons Plus addon. I found a note about that on the addon page: ***PLEASE NOTE*** Some options may be incompatible with Firefox themes that deviate from the standard theme in significant ways.

Known issues: -Menu Icons Plus is not compatible with the CuteMenus or CuteButtons add-ons.

But maybe it's not the theme. So one other thing you could try is leaving Menu Icons Plus enabled and disabling all other addons to see if the glitch still happens. If it does, then the author will have to fix it. But if not, you can slowly enable your addons 5 at a time and check to see if the glitch came back. Then disable each one in that bad group individually and restart Firefox until enabling one of them causes the glitch. Same steps as before. But if you find out which addon is conflicting with Menu Icons Plus, it can help the author come up with a fix faster.

You're welcome, anytime. :) Let me know if you find out what was conflicting with Menu Icons Plus. Maybe Personal Menu? I'm curious myself.

Hey,

I already did contact the add-on's developer and illustrated the glitch to her/him using a screenshot.

Meanwhile, I also did some more research and found out something interesting: The glitch only occurs when Menu Icons Plus 3.1 and OmniSidebar 1.4.7 are activated both at the same time. I tried by deactivating all of my add-ons except for Menu Icons Plus 3.1 as well as OmniSidebar 1.4.7, same result. Only having OmniSidebar on will not produce the glitch, nor will only having Menu Icons Plus activated do so. But as soon as you activate both, you get this glitch.

While I had only these two add-ons or one of either activated, I also tried out various skins and themes. I only have one "full" theme (SimpleWhite 2.2.1) which requires a restart (I did a restart manually after every change even when it was not required anyway, by the way - just to see what changing things would do to the glitch). Using this full theme did not fix or influence the glitch in any way. Then I chose the default Firefox skin ("Persona" I believe they are called?) and restarted, same result. Then I went back to my original persona (Soft Spring Blooms Purple), not affecting the glitch either.

For now, the best solution for me is to leave OmniSidebar deactivated and Menu Icons Plus activated. Perhaps I should also tell the creator of the OmniSidebar add-on about it? You don't happen to know how to reach that person also? ;)

Oh and of course I will inform the author of Menu Icons Plus of what I found out so far and wrote here, too.

Kind regards
