Wayfarer page becomes very slow and locks up in Firefox browser. Map slow to load and populate.

I recently started noticing this issue on my PC while reviewing, after completing a handful of reviews the page would start to slow down until eventually it reaches essentially a locked state where nothing works. The issue is more pronounced when reviewing on Mobile and can happen in as few as 3 reviews.
The issue is specific to the Firefox browser and does not happen at all in Chrome.
For the record, I typically review with several add-on scripts via Tampermonkey. This problem occurs even when Tampermonkey is completely disabled and still occurs after clearing my plugin cache.
Additionally and possibly related, I have observed that while this is happening the map on the review page will sometimes not load at all, and other times will have only the background tiles loaded and none of the nearby markers or other information.
At least a half dozen other folks have mentioned this issue and particularly on mobile it is "game breaking" to the point where we simply won't review at all.

chiming in that i have the same problem. i think it started around the time the jump to streetview "bug" arrived, so it's been a couple months. before that, i would review on firefox mobile all the time without any problems. now, if i get to a review that has street view/a photosphere (usually just one or two reviews in), it glitches and freezes up. it's practically unusable. i have to exit the tab and start a new one just for the same thing to happen again.
on desktop firefox browser, it doesn't freeze up for me, but after about 10-20 reviews my laptop fan will kick on and it'll start to lag a bit. after talking to tehstone and some others i learned that part of the problem is my laptop's memory/ram is very low (4GB).
i also use tampermonkey plugins but as tehstone said, disabling them doesn't seem to make much of a difference.
Other notes on this, once it kicks in you will notice that the Refresh/Cancel button in the browser will be very rapidly cycling between the two states. After a lengthy review session on PC this morning the issue has not presented itself as seriously as it was a week ago but it still happens almost immediately on mobile.

It works fine on Brave for me. If you're using Firefox for privacy reasons (keep at least a little something away from Google), Brave is secure and works great.
thanks. on mobile i use it in order to have access to browser plugins, i'll have to see if brave supports those at all.
