If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Thanks for at least trying to help me out. I do appreciate it even if it didn't solve the problem.

Hello davelp,

Would you check this please :

Type in the address bar about:config (press Enter) (promise to be careful, if asked)

Type in the search bar and look for the preference :

network.http.sendRefererHeader

And make sure that its value is not set to 0 (zero)

default value is '2' - you could use a value of '1'

See : http://kb.mozillazine.org/Network.http.sendRefererHeader

Note: If you have to change the value - don't forget to close and restart Firefox.

(you'll have to scroll down some)

'Hope this helps ........ (fingers crossed)

Again I thank you for the attempt to solve this for me. The RefererHeader value was already set at "2" so that apparently isn't the issue. I got a Firefox update several weeks ago but I don't know if that is the source of the problem because I don't know if the problem arose before or after that update. I hadn't posted items for sale on Craigslist for several months.

Hello again davelp,

As none of the suggestions solved the problem for you (bummer  !), may I suggest that you contact Craigslist :

https://sfbay.craigslist.org/contact

One last stab in the dark though : if you have any security software installed, would you disable it (for now) and see if that will make a difference  ?

I actually contacted Craigslist first about 4 days ago and again 2 days ago and have yet to hear from them. I did disable my antivirus as you suggested and it made no difference. I think it could be a Craigslist issue because they recently updated their site to eliminate their "Personals" section due to some Federal law. Who knows what else they may have done. Again, thanks for trying.
