All sites stop loading after Firefox is open for a period of time.

Posted

FF 36.0.1, WIndows 7 Pro x64, fresh build and fresh install.

After running FF for a period of time (that varies), all sites return a server not found error. Other browsers still allow access. The only fix is to close and relaunch.

There is a chance you have an issue with your proxy settings and their updating, make sure you have your proxy set to automatic detection.

You do this in the FireFox options under the Advanced > Network > Connection >> Settings and choosing either Auto-Detect or Use System Settings

Hope this helps!

No proxy server here at the house. Currently set to "No Proxy", but have tried "Auto" and "System Settings".

I have also set network.dns.disablePrefetch to true and network.dns.disbaleIPv6 to true

Try and set those to false while enabling auto or system and see what happens. That might be causing a majority of the problem.

These settings were enabled based on other forum posts, and were set after the issue was originally found. I will adjust back in 37 beta, but will not know if it helps for at least 2 hours and possibly 24 or more hours.

This sounds like the same issue reported by another user here: Server not found in Firefox 36 -- not solved. ("Using wireshark; I can confirm that there is no DNS packet sent when issue occurs.")

I was having this same exact problem for the last week. It started happening after Firefox updated. I tried a few different things that didn't help. I tried uninstalling and reinstalling which didn't help either. I finally fixed the problem tonight.

Here are the steps I took to fix it. Make sure you are logged into sync and hit the sync button to update it. This will save your bookmarks and user settings.
If you want to be able to restore your current session go into your main drive and click users, your user name, AppData, Roaming, Mozilla, Firefox, Profiles, open that folder and copy sessionstore-backups and save it to your desktop or somewhere you can remember.

After you have done that uninstall Firefox. Now restart your computer into Safe Mode.

Go into your main drive usually C on most computers and click users, your user name, AppData, Roaming. Click the Mozilla folder and delete it. Now hit the back button and click on Local. Find the Mozilla folder in there and delete it too.

You can now restart your computer and install a fresh copy of Firefox. Once it is installed you can log into sync and it will restore all your settings and bookmarks. 

If you want to restore your previous session close Firefox and make your way back to AppData, Roaming, Mozilla, Firefox, Profiles, open the new profiles folder (Example: abcd1234.default) and paste the folder you saved called sessionstore-backups in there.

You can now open Firefox and all your tabs will be there, and after a few mins all your settings and bookmarks will be restored by sync. You shouldn't have any more problems following this method. The pages no longer stop loading and it closes like it is supposed to.

Lots of work, but if it works.

As to saving your profile,

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backup of files that you choose.

OPIE {web link} Import/Export extension preferences

That would be great, except my copy was installed as 36.0.1, never upgraded. The OS is new on this machine and was installed 3/14.

Hi attogtech, is there any difference if you disable the HTTPS Everywhere and Privacy Badger extensions?

Do you notice any patterns to this or does it occur randomly?

Tried, but no luck. Turned them off for the last 24 hours. Also, with the latest version of 37 I am now having issues changing tabs sometimes.
