Firefox 62.0 no loading tabs in background
Browser tabs often do not load in the background after updating to Firefox 62.0. (I have confirmed that the value is listed as "true" in the browser.tabs.remote.autostart section of about;config as suggested in a previous post) Further, when I click on the tabs and wait, those tabs are slow to load or fail to load.
The only work around that I have found is to fully close the browser and relaunch. Sometimes this resolves the issue and other times have to re-start it several times. But this is not practical solution as it takes too much time and interrupts my work.
I do not have any extentions installed (not even a single one) and I am using the default theme.
Hi jschaar, do you mean you direct a link to a new background tab (e.g., right-click > Open Link in New Tab) and the page stays blank until you activate that tab, and only then does it start rendering?
Some pages have a kind of "lazy loading" logic that delays rendering until they gain focus. I don't know whether Firefox itself has a feature like that, but if it does, I haven't noticed it.
That is exactly what I mean. I right click to open one or more links in a new tab(s), and when I click over to a new tab it has that spinning image in the center of the page instead of the loaded/rendered the content.
Most of the time the content never loads, requiring me to shut Firefox complete down and start all over again. Even if it does load, when I click back to the previous tab that tab, I see the spinning image and have to wait for the page to load/render again. Because of this I would suggest that it isn't an issue involving lazy loading, as once the content is loaded/rendered it should remain in memory for me to immediately view when I go back to a previously loaded/rendered tab.
And, as noted in my original post, the I searched this issue and checked to confirm that the browser.tabs.remote.autostart section value was set to "true". According to the previous posts, the "true" value was the setting that allowed background tab loading/rendering.
Multiprocess Firefox usually divides up the various tabs among about four different content processes. If one of the tabs in a process "hangs" or starts using an inappropriate amount of resources but doesn't trigger Firefox to show the bar with the option to stop loading that tab, other tabs in that process will also be affected. Unfortunately, I don't know of a way to figure out which tab is causing the problem and "kill" just that one. I have this problem with one specific page, so I usually can close the problem tab and Firefox will calm down after 10-20 seconds. If you don't see such a pattern, maybe someone else is aware of a tool to figure that out.
The reason for the above comment was I only ever see the loading animation in a tab when that process is struggling.
