Posted

I just upgrade to versions 18.0.1. I am suing Window 7 64 bit.

Now I while I am viewing a page I suddenly receive the error massage "Oops! This page appears broken. DNS Error - Server cannot be found."

I can use the back arrow key to bring the paper back.

If I have several tabs open, I can watch one tab after another change from the page name, It doesn't seem to matter who page it is, Yahoo, Washington Post, NBCNews,

Are you using pdfforge extension ?


Try the Firefox Safe Mode to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open the Firefox 4.0+ Safe Mode by holding the Shift key when you use the Firefox desktop or Start menu shortcut.
  • Or use the Help menu item and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Don't select anything right now, just use "'Start in Safe Mode" To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shift key) to open it again. If it is good in the Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one.

Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Question owner

I am not a techie. I keep 15-20 to tabs open at a time for reference while working. When I upgraded to this version, all my tabs were closed and my history was erased. I still have not recovered from that loss. I do not want to have this repeated!

If I was using pdfforge extension (what ever that is) before the upgrade, why is it venomous now?

Besides this issue, since upgrading I suddenly starting having the audio from commercials being played from tabs that are not active (open). I now have to leave my audio muted.

I expected assistance from Firefox not some unknown individual ( iamjayakumars) who for all I know is a troll trying to get me to do something to expose my computer to attack.

I allowed Firefox to collect data they needed from my computer when I submitted the question.

Fix the bug in your program! I have used Firefox since it came out. I am within a hairs width of switching browser. The only thing holding me with Firefox is my bookmarks. If I figure out how to export them, I am gone.

FIX YOUR BROWSER!!!
