Specific sites (Twitter, Reddit, Google/Youtube) have page loading issues after enough time/tabs open in session

What happened?

After having Waterfox open for enough time/opening those sites enough time, or hitting a certain threshold of tabs or memory usage (not sure which, but at one point I had multiple twitter tabs open and loading, and literally saw the tab icons/favicons change as the issue happened and they stopped loading right), tabs with pages open from those sites will stop loading correctly, and either will cease to load the page at all and the tab will break and not load other websites too, or will load partially or very slowly, or will otherwise become unstable.

Note that this happens to each site separately: It can occur for Twitter, but Reddit will load fine untill it also happens to reddit. Likewise, it happens to normal vs private browsing separately: If Twitter works poorly in normal browsing, it will work fine in Privae tabs untill it happens there too.

So far it has only happened with Twitter, Reddit, and Google/Facebook, in that order of frequency: Twitter it always happens to after a day or so of having a browsing session, Reddit it happens to less frequently, maybe after a few more days, and I've only had it happen to google/youtube a single time in the weeks I've been using waterfox.

Lastly, it is worth noting that I often have literal hundreds to thousands of tabs open at once and hit my maximum RAM usage pretty frequently, so I wouldn't be suprised if the issue is related to that, but still, the loading problem isn't an issue I have had with other browsers: Other browsers will sometimes have tabs crash (which is easy to deal with, I can just refresh them) or the whole browser slow down (which tends to happen with some Firefox derived browsers, like Palemoon, which I try to avoid now as a result), but I've never had this sort of issue with specific websites happen.

At this point, I am ready to uninstall waterfox like I do Palemoon and some others because it's creating a lot of issues for me, so I am hoping it can be resolved, since otherwise I like the experience.

Reproducible?

@jabberwockxeno - This certainly is a weird bug. One suggestion for G4 would be to try utilising the "Unload Tab" option on any tabs that are acting up. If you cannot see that when right clicking on any non-selected tab, head over to about:preferences and turn it on under Tab Context Menu. If that doesn't work, we will be releasing G5 in the next month or so which should give some significant performance upgrades.
