When starting FF23, context menu is huge, then is smaller after a few minutes and the copy & paste are gone.

I downgraded back to FF22 and the problem has vanished - I did all of the things that were mentioned in the forum - safe mode, and all. The context menu is huge when first starting FF23, no matter where on the page that you right click, and includes copy & paste amongst a plethora of options, then after a few minutes and/or link clicks, it down sizes to almost nothing, and you can select ordinary text - it highlights as expected but then when you right click to bring the context menu to copy, there is no copy in the list, or paste for that matter. I have searched the web for several days now with no plausible answer. In previous versions I did not have this issue. Consequently, I have disabled auto update because of this issue. I saved my profile from FF23 and re-loaded FF22 and then restored the profile folder in Application settings. Of course I would mention that this is Win XP SP3 - I also have FF23 installed on an WIN 7 LT and HAVE NOT experienced this issue. My suspicion is that there is now a OS compatibility problem with FF23 and Win XP SP3. So Mozilla has finally forced some of us to vista or higher - get this - Microsoft's answer to my query for WIN 7 is "your computer does not meet the requirements for Windows 7 - why not upgrade to a newer computer. May we suggest...". Yea, right - I'm on fixed income and lucky to have this one. It would be nice that if you become incompatible with an older OS, why not tell someone before you just bust in and "update"......I am currently back to FF22 so the lower box troubleshooting is not applicable to this issue and consequently unable to show any.

That sounds like a compatibility issue with an add-on that you have installed, as reported by a number of users in both Firefox 22 and Firefox 23 over the last couple of months. If you would provide a listing of your installed extensions (as you were prompted to do when creating this thread) maybe one of us can advise you which extension is the mot likely culprit. You will need to re-install Firefox 23 to do further diagnostic testing.

As far as the compatibility of Firefox 23 and Win XP SP3, Mozilla has verified they are compatible and not one user (including me on two separate PC's) has reported a problem with compatibility.

Extensions: Adblock Plus 2.3.2

The plugins above were used in FF23. I will re-install FF23 and send the list of plugins I had installed, but just to be clear the one plugin mention in a few posts is not my issue - I don't have that plugin.

Nitro PdF for FIrefox and chrome 3.5.5.2 ShockwaveFlash 11.8.800.94 Silverlight Plugin 5.1.20513.0 Windows media player dynamic link library 3.0.2.629 Java deplyment tool kit(already disabled but I cant remove it) updating it does zip - it always remains.

Thanx
