firefox tabs loosing internet connection until I can't open any new pages

currently running 153.0.1, in Windows 10 I started having trouble with web pages not working (I have auto-tab discard, so after a while the pages go dormant and when I go pack in they have to refresh) only they wouldn't refresh I'd hit refresh and it would stay blank but if I opened it in a new tab it opened fine (noted this first in tumblr and youtube - probably since previous to last update) also opening links from an 'affected' (youtube video page that stops working) will also have those new tabs blank and eternally trying to load then yesterday the problems ramped up; other pages start not working, not when I refresh, not when I open a new page. youtube videos will just stop loading, yahoo's inbox displays "no internet connection" warning (even when I can scroll tumblr, but the links still break) I can access those same pages and others normally in other browsers also if I just keep working in the still half broken pages it gets to a point firefox simply stops allowing me to do anything on new tabs, it gets slower and slower, taking up to a minute to open one page (internet fine in other browsers). eternally frozen in loading pages do not allow me to access settings or react to pressing Alt, or pressing "stop loading" I tried deactivating all extensions, I tried (and am currently writing this in troubleshoot mode) it still happens if I restart firefox it works for a bit, and then starts breaking, timing seems rather random, (once it happened with one youtube video and one mail tab open, other time's i've opened several youtube videos a couple tumblr pages and one mail tabs (easiest to notice the "no internet connection in the mail tab) hope this info helps
