Firefox 157: Nova interface, how do I revert back to the previous gui?

Regarding FF v157:

- Mozilla have changed the Graphical user interface of Firefox without asking for consent or providing a clear way to revert back to the old interface, yet again. - They have made changes to the settings, so pre-installed search engines can only be toggled off and NOT removed... - There are a bunch of themes now pre-installed that can't be removed.

I think pushing a change without over way to revert, is why I a lot of people don't donate to the Mozilla foundation

I need help with MacOS Sequoia 15.8.1 (24H32).

Since yesterday’s update to 15.8, Firefox and Thunderbird no longer work—regardless of the build or version. The system immediately terminates the apps with this message in the Apple error report:

System Integrity Protection: enabled Crashed Thread: 0 MainThread Dispatch queue: com.apple.main-thread Exception Type: EXC_GUARD (SIGKILL) Exception Codes: GUARD_TYPE_MACH_PORT Exception Codes: 0x0000000000000203, 0x0000000000000000 Termination Reason: Namespace GUARD, Code 2305843146652647939

So PDF's can no longer be set to open in Adobe, but it now requires clicking before the document opens in Adobe. No setting whatsoever can change this. Is this a permanent setting? Will have to move to another browser now. What a hassle. Got to move bookmarks, set up home pages etc. Ugh. Bey Firefox....

Hi, my spell check only rarely works, I have tried adding more dictionaries, but as it works sometimes, I assume it is something else that is the problem, I had asked about this in another thread, but cannot find it.

So basically if I right click there is no spell check option most of the time. I have also installed LT check spelling and Grammer, not if that interferes with spell check, I feel I had this installed after the problem started, I tried disabling it, but spell check still only activates intermittently.

I just updated to Firefox Version 157.0 and set up vertical tabs on the left side and love it. I also have "Hide tabs and sidebar" clicked which I assumed would hike the sidebar until I moved my cursor to the left. That doesn't happen. The icons for the various tabs remain displayed. Am I wrong to assume that this setting means the sidebar will be hidden until the cursor is moved to this area?

Thanks for your input.

In the recent month my youtube loads very slowly and when the video finally loads, the comment section, the recomended videos, and the left panel with subscribed channels dont load. A trick for faster loading is to click on a video, then ctrl+R to force refresh. This speeds the loading, but the above sections still dont load. Turning on the built-in VPN immediately makes youtube works properly: everything loads fast and fully. But the moment i turn-off the VPN - back to the problem.

I tried disabling all addons. Restart mozilla. Loading youtube in incognito. Clearing the cookies for the site. All of the above. Nothing helps.

I'm sure the problem is mozilla-related, because on another laptop connected to the same wifi everything loads fine. On my laptop, on chrome everything is fine. Loading videos from different sites works fine.

i found this article with similar problem: https://support.mozilla.org/eu/questions/1508828 but solution there seems to be updating the ublock's filters. I followed the steps mentioned, but my problem is still present.

図のように、ページの中に青や白文字で青背景のポップアップが出てきて、サイトに関連する単語でgeminiが文章を生成するということがしばしばほかでも起こります。

これがwebサイト側の問題なのか、端末の問題なのか、firefoxの問題なのか検索エンジンのGoogleの問題なのかがわからないです。解決できる方がいたら教えてください。できれば消したいと思っています。
