At times, built-in Session Restore restores tabs as blank (about:blank, actually).
Don't know if it's pertinent?

I have PM set, on Startup, to, Show my windows and tabs from last time, & Home Page: as about:blank.
I installed uBlock Origin 18.104.22.168 & that's about it.
I quit from, File | Exit.
This occurs even after removing uBlock.
"Tab history" (right-click on the back-arrow) may show actual history, or may show about:blank or combinations depending on how much history a tab has.
Two windows, four tabs in each.
Started with a new Profile. Only changes as noted above.
Win7 x64, PM 22.214.171.124 x64.

Oh, & some times, a tab (not focused yet) will
show the correct name
, but when you actually focus the name, it reverts to about:blank.
Setting Home Page: to default, Pale Moon Start Page, does not change anything.
Alt | File | Restart... does the same.
In my case, only dealing with only two windows, the first window does not appear
to be affected.
The first tab in the second window seems to persist. All others are likely to end up end up blank.
Changed the browser's behavior when restoring tabs from previous sessions. To prevent stale pages, it will now by default perform a "soft refresh" of the page instead of drawing it purely from cache without checking if the page needs updating. If you prefer the old behavior, set browser.sessionstore.cache_behavior to 0 in about:config.
A quick looks says that's it.
Can you push a "soft fix" to revert that Pref?
I'm running the Portable version of PM.
Portable disables /cache/ by default.
But setting browser.cache.disk.enable;true does not help me for this issue.
So far, only setting browser.sessionstore.cache_behavior;0 works.
(Separately, the long standing issue with closed windows being restored on opening from Session Restore still exists, & also window ordering along the [Windows] taskbar.)
