Firefox Tracking Flags

(Not tracked)




2 years ago
User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20150511122605

Steps to reproduce:

Paste in the address bar. Note: the machine currently doesn't answer to ping; in the future, this URL should be changed to one with a similar problem.

Actual results:

After some time, the page loading stops. "View Page Info" says about:newtab (with the default profile, but it can also be about:blank if one has changed new tab configuration to that), and the page is not reloadable (to retry the connection). When Firefox is restarted, the tab is missing.

Expected results:

One should get a "Problem loading page" error message with a "Try again" button and the right URL in "View Page Info", like when the server is not found, e.g.

At the URL

Chromium eventually gives the message 'This web page is not available | ERR_CONNECTION_TIMED_OUT' with the option to 'Reload'.

If you paste the URL into the address bar, Firefox (after a long time) ignores it and writes the current URL back in the address bar. If you open the link in a new tab[1], Firefox gives you an empty tab as described by OP.

I'm not sure it's the related issue or not, so i posted here.

If you right click on a timeout link like ""(got rare case it did shows) OR "", then select "Open Link in New Window" OR "Open Link in Private Window", it will:

[1] Open the window with blank url bar.
[2] You can't refresh by F5.
[3] The bookmark can be star once, then become grey, and if you check in bookmark manager nothing actually bookmark. 

The expected behavior should shows URL, otherwise i have no idea which URL cause it(in case i clicked a lot of links).

I also found if the click bookmarked URL from "Recently Bookmarked" OR "Library", if the URL timeout, then it will displays blank URL bar too.
I also see this from time to time. When a page doesn't load properly, the URL isn't kept in the URL bar, and you can't refresh the page. I think we should handle this somewhere in the UI code.

I come across this issue on extremely low-speed Wi-Fi networks. It can cause a data loss when restarting Firefox and expecting it to open the tabs from the last time.
