Firefox lockup on Yahoo Mail and failed session restore
I am currently using a Yahoo Mail account and have been for years but recently when on the yahoo mail page I get a red notification tellimg me I'm not connected to the internet on the tab displaying Yahoo Mail.
All other open tabs are able to access the net with no problem.
The only way to clear the issue is to open task manager, select all user info whereupon I will see one or two entries under Firefox using massive amounts of memory, i.e most open windows will have between 4.000k and 10.000k allocated but the top two entries arranged under memory use will both be firefox showing around 13.000.000k and 1.500.000k but with no information to identify which tab in firefox is using that amount.
If you select the 13.000.000 and end process, it ends that entry and nothing happens, if you then end the 1.500.000 process it crashes firefox and every single tab and window closes.
Restart firefox and it will open with the session restore page, hit restore existing session and watch the pages reopen and one iteration will head for the 13.000.000 mark again and Yahoo will not load at all.
It usually takes one or two more crashes until the session restores and Yahoo Mail loads and opens as if nothing has happened.
Today however after 4 attempts I eventually got a cannot find server notice on the yahoo page so I hard reset my router and after manually diabling and re enabling my network adapter my computer re-established a newtwork connection but when I restarted Firefox again the restore session was greyed out and only the new session button was available.
In the new session it loaded Yahoo mail immediately and when I tried to see if I could manually restore the session using the top right menu button, there is no session restore information or button at all.
Go to the history tab and there are no closed tabs or windows ( both greyed out) but the recent history display and the history itself is showing all the previousl pages.
I searched online and found this link https://support.mozilla.org/en-US/questions/1267353#:~:text=If%20your%20tabs%20disappeared%20and%20the%20previous%20session,3.%20Close%20Firefox%20Delete%20sessionstore.jsonlz4%20file%20More%20items but none of the information in it matches anything in my file system even though I too am still using Windows 7. This is the version in the update history Firefox 108.0.2 (20230104165113) Details Installed on: 6 January 2023 at 15:40:33 Status: The Update was successfully installed
Can anyone help with the why one particular tab in firefox keeps trying to monopolise memory use for itself and how to stop it, and whether there is any way to recover the previous session information as I can't find anythig remotely relating to it on my system at all:-(
Did you also try Private Mode browsing to verify if this wasn't caused by Addons or not?
I haven't used Private Mode Browsing at all, it happens in normal browsing and I'd assume any addon would be active in any window?
On each attempt to restore after crashing, one tab will use massive amounts of memory and Yahoo Mail will not even fill in the address bar with the address.
Crash Firefox multiple times and eventually it will restore all windows and tabs and none of them will use that much memory until I come back to Yahoo mail at some point in the future and there will be a red notification saying no internet connection again and some unidentified tab will be monopolising all the memory again:-(
By default if the user didn't turn on Addons in Private mode they will be disabled otherwise you will have to disable them in Private mode to verify nothing is interfering with yahoo email.
