Bugzilla – Bug 1125078
Firefox under Gnome - loading page in a new tab prevent pages on other tabs shown
Last modified: 2019-02-21 02:35:47 UTC
Environment: openSUSE Tumbleweed, dist upgraded to snapshot 20190205 MozillaFirefox-64.0-1.4 Steps: 1. All add-ons disabled. 2. There are some web pages on different tabs. 3. In a slow network environment, open a website (eg. wikipedia.org) in new tab. 4. While it is still loading, switch to another tab. Results: The pages on other tabs will automatic reloading. Tried on a fresh installed TW instance, the problem existed. Searched on bugzilla.mozilla.org and did not find any similar issue.
Created attachment 796560 [details] Screenshot - other_tabs_loading BTW, it is on Gnome. Maybe just because it is slow, or display latency?
I found sometime after I close a tab with a web page just refreshed, firefox switched to another tab automatically, that page was in reloading status.
I found this issue is only occurred on GNOME. (I have check on KDE, it did not show the issue). So I re-assign it to GNOME team. BTW. It is more likely a performance issue rather than logical bug.
Please try fontconfig packages from https://build.opensuse.org/package/show/M17N/fontconfig If that solves the problem, this is not a GNOME issue.
I can confirm the behaviour for XFCE (and the dependency from fontconfig) too After installing snapshot 20190209 Firefox became unuseable. Stumbling over https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=909818 and https://www.preining.info/blog/2018/10/firefox-got-maniac/ I rebuilt fontconfig-2.12.6-2.4.x86_64 and fontconfig-32bit-2.12.6-2.4.x86_64 from another (older) installation and with those applied everything went back to normal.
Please reopen if not fixed by fontconfig package from M17N (https://build.opensuse.org/package/show/M17N/fontconfig). *** This bug has been marked as a duplicate of bug 1124816 ***
Thank you, the fix works. One tip, it need not only fontconfig package, but also libfontconfig1 to be installed.
