159.0 (aarch64) still has many issues across sites.

I have cleared the cache on these sites. I have removed cookies. Restarted the browser. Restarted the computer.

On Instagram and YouTube especially, when you click their tab, many times the page is now blank, you canot reload it, it just dissappears. If ti is there, clicking around is extremely slow if not unresponsive.

It is a tad better in the latest update, a small tad, but still very much broken from previous release.

I have a screen recording

안녕하세요

파이어 폭스를 애용하고 있는 한국인입니다

저는 최근 (약 2026년 10월 동안) 파이어 폭스를 사용할때 컴퓨터 팬 돌아가는 소리가 계속 들린다는 사실을 꺠달았습니다

작업관리자를 통해 확인해봤는데 제 컴퓨터에 설치된 램 64GB 중 34GB를 파이어 폭스가 사용하고 있다는 사실을 알게 되었습니다

확실하게 버그 같아 보이고 그 정도의 용량이 파이어 폭스에 필요한지 모르겠으나 만약 의도한 설정이 아니라면 꼭 고쳐주세요

사진을 첨부합니다 이 사진이 찍을 당시 파이어 폭스로 켜져있는것은 유튜브 창 두개 커뮤니티 창 하나 였습니다

감사합니다

The problem of hanging on specific web pages but not always in the same place greatly increased 11/22/2026 running Firefox 115.38ESR under Windows 7 so I suspect that it is due to some widespread update and a new esr update is needed. 115.43.1esr did not help. Sometimes it happens while loading a page, sometimes when attempting to scroll the page and sometimes when entering data into a field.

I've used Firefox for years and am embarrassed to submit this question via Chrome. Lately, almost invariably after updating, Firefox shows "not responding" if you click anywhere in the window. Eventually, maybe after half an hour, it does respond, and everything works like it always did. If this is normal behavior for Firefox, so be it, but it seems peculiar to me. Advice?

I'm having an issue where when you try to do things in-browser, Firefox freezes, puts up a grey screen and holds this way for a few seconds. Scrolling and video seem to trigger it most often. Repeatability is nominal; sometimes I have no problem, sometimes every action I try to take results in another fit of grey screens and freezing.

I'm using version 153.0.3 64bit on Windows 10.

I have turned on compact mode, so i have to hover to the left side to access it. I usually go to the left side, it appears and i do what i wanna do. But today, when i go to the left side it appears as usual but automatically disappears again without me doing anything. Also if i click on something on the toolbar it does not register but it clicks on whatever website that is underneath it. It doesn't happen all time though, sometimes its working like before. I don't know how to find the exact cause.
