As I’ve mentioned in passing before, I have been a member of Christian Forums for five years now. Over the last two days, my computer automatically downloaded and installed the upgrade to Firefox 3.0.9. Since that upgrade: 1. I can access CF by the pre-esxisting bookmark, which is to my User CP listing subscribed threads. 2. I can sometimes but not always get the main menu listing of CF forums (equivalent of the page that lists GQ, MPSIMS, etc. here) 3. I cannot open any of the forums or threads. What I get is “400 Bad Request / nginx/0.6.35” 4. When I wised up and looked at page info on that list, it informed me that the site does not encrypt, and that others can see what I send. (Since what I send is my posts, this is hardly an issue.) 5. I can access CF using MSIE, though I hate using that program for doeznes of good reasons, including security against viruses. I cannot find any way to convince Firefox that I actually do want to access CF and navigate around that site. Any experiences in coping with this? Any clues as to what I should do? ---

I can’t help you, but you may want to follow this thread: [http://support.mozilla.com/tiki-view\_forum\_thread.php?locale=tr&comments\_parentId=340559&forumId=1](http://support.mozilla.com/tiki-view_forum_thread.php?locale=tr&comments_parentId=340559&forumId=1) Erm, unless it’s yours. Some sites block Firefox automatically to prevent people from viewing their pages while using AdBlock, but you said it’s only been happening since you upgraded… ---

That would be mine – I neglected to mention I went to the Moizilla help site before asking here. ---

The most recent Firefox upgrade was to 3.0.10, specifically to fix some issues with 3.0.9. Try updating, see if that helps. ---

Got the answer to this from a Firefox user on their help site. I’m documenting it here so that anyone with the same sort of problem will know what to do: Clear the Cache and Delete the Cookies from site(s) that cause problems: Tools \> Options \> Advanced \> Network \> Offline Storage (Cache): “Clear Now” Tools \> Options \> Privacy \> Cookies: “Show Cookies” On the latter, for obvious reasons, you only remove the cookies from the site(s) causing problems. ---

Polycarp: Yeah. I had to do that for Gmail of all things.
