hello, in this thread a user has found out that the problem might be related to the ghostery addon - do you have it installed too?

madperson, Thanks for the quick response. No, I do not have the "ghostery addon" that you mentioned. I have very minimal addons as I use my computer only for e-mailing & internet. This problem just appeared overnight for no apparent reason and I have tried emptying the cache, clearing cookies, checking that Javascript was enabled, etc. Nothing has solved the problem. I strongly prefer to use Firefox as my browser but may have switch back to IE as that is the only way I am able to send E-mails.

could you test if the site is working correctly when you launch firefox in safe mode once too? thanks...

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

Ghostery seems to have been the problem for me. I paused the blocking, and voilá, I could type an email again.

Okay, I "disabled the ad ons", restarted Firefox in the safe mode, and my E-mail is now working properly once again! Thank you madperson & Rhonda for your responses and information. I am an amateur (as you can probably tell) and sincerely appreciate your help & assistance. Are there any negatives to my having "disabled the ad ons"? Will it affect any other computer operations, do I just continue using it as it is now, or will I need to perform any other future operations? Will I need to "disable the ad ons" each & every time I restart my computer? Thanks again, Phillip.

hey phillip, the addon should stay disabled after a restart.

however you also could reenable it again & just add an exception for yahoo mail: click on the ghostery icon while you're in yahoo's webmail, choose "edit blocking options" & then don't block on this domain...

The way I fixed it was close to, but not quite the same as madman advises. I wasn't in yahoomail at the time. What I did was

1. went to yahoo mail, and in the address bar, selected the URL up to and including ".com", but nothing after that

2. copied this selected part opf the URL to the windows clipboard by pressing control+ c

3. exited yahoo mail

4. clicked on the ghostery icon, chose "edit blocking options" & clicked the "site whitelist" tab

5. put my cursor in the "add new site" box and pasted the portion of the yahoo URL which was on the clipboard, by pressing control + v

6.clicked "save" at the bottom

After this yahoomail worked fine.

Thisis basically what madman said, just slighlty more explicit for newbies

If you do it this way, you get to use both yahoomail and ghostery. I certainly want to use ghostery while on yahoomail because yahoomail has a lot of tracking "bugs" which I want ghostery to block

This weas a really aggravating problem -- I was ready to defect to Chrome -- so thanks guys for ID-ing ghostery settings as the culprit

Mozilla team --I know you can't consider every combination of variables when you upgrade firefox; but given that yahoomail and ghostery are both very widely used, you really should test how they work before you release. Otherwise, less patient users night indeed dump you :-/

madperson, The "fix" was temporary. When I tried forwarding E-mails this morning I was unable to. Went through the "disable add ons" & "restart Firefox in safe mode" & it's working properly again. My question today is about Ghostery. I don't see that listed in my add ons list and I don't see any Ghostery Icon when I'm using Yahoo Mail. What does this Icon look like & where should I be looking for it? If I don't have Ghostery, is there any other permanent way to resolve the problem? Thanks.

hello, since you already said before that you don't have ghostery installed, the problem might be caused by a different addon. what is listed under firefox > addons > extensions?

I see no "extensions" in my add on list. The 8 add ons on my list are: Adobe Acrobat, AVG Sitesafety, Coupons Inc., Google Earth, Java Deployment, Shockwave Flash, Silver Light, & Windows Presentation. Does this help any?

the ones you've listed are plugins & they shouldn't play any part in the issue, since they also stay active during firefox safemode.

as an alternative please try a general reset of firefox (this will keep your bookmarks & passwords): Refresh Firefox - reset add-ons and settings

madperson, Followed your instructions & Reset Firefox. I'll know in the morning if the problem is permanently resolved, I'll let you know. Thanks again for all your help & advice, Phillip.

Madperson, The "Reset Firefox" appears to have resolved my Yahoo Mail problems with Firefox. Thanks again, Phillip.

it seems to be GHOSTERY - i Whitelisted "http://us-mg6.mail.yahoo.com" and now i'm okay, can reply, compose...

If the above does not help ..

Not sure this will help anyone but here is what you do check that you are not blocking Yahoo Analytics as I blocked all cookies.

I did this in the AVG Do not track in the AVG toolbar and could not use the yahoo email e.g . compose , see attachments and forward. Allow Yahoo Analytics all working great now ..

Hope this helps someone ..

I had the same problem and discovered it went away when I disabled the AVG Do Not Track extension on firefox.

FIXED: Madman's response about hitting the link to this other website worked for me:

Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

My problem ended up being the AVG Toolbar Extension - disabling it fixed the problem!!!!

Being a "non PC" type person...The foregoing has me slightly baffled... HELP...!!

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

• https://support.mozilla.org/kb/Safe+Mode

If it works in Safe mode or with all extensions (Tools > Add-ons > Extensions) disabled then try to find which is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Thank you very much. I did what you had advised and my problem has been sorted out. Thank you very much once again,
