Per Updates critically important open tabs were no longer accessible following the Updates in question. I need to recover the missing activity-chronic or request that the unfinished activity up to the point of Update be retrieved.

I am experiencing a severe issue on the LINE Official Account web app (https://chat.line.biz) using Firefox.

Problem Details: 1. Every time I switch between customer chats or type a reply, the chat window automatically jumps/scrolls up to old messages (sometimes minutes prior) instead of staying at the latest message. 2. It happens consistently across almost all chat threads, forcing me to manually scroll down every single time.

Troubleshooting already attempted: - Cleared all Cache, Cookies, Local Storage, and Session Storage. - Tested in Troubleshoot Mode (all extensions disabled). - Toggled layout.css.scroll-anchoring and general.smoothScroll in about:config. - Issue does NOT occur on Chromium-based browsers (Chrome/Edge).

This seems to be a compatibility issue between Firefox's DOM re-rendering/scroll anchoring mechanism and LINE OA's React web app code. Please help investigate.

This first happened a few days ago and I successfully recovered my book marks from backup. It has now happened twice more. I can't be sure, but it seems possible that this happened each time after installing recent updates. Note that my recent history has also vanished.

I just switched to firefox from edge, and so far I really like it, but I got an issue with scrolling through youtube home page, it's laggy, and the lag is present 95% of the time. This is not happening in Edge or Chrome. This might be subtle to people using 60hz screens but for me it's noticeable and annoying, its as if the FPS drops from my set 144 to 30 or something. Is there a way to fix this? I really want to keep using Firefox :(

Environment:

Firefox on Windows Web app prints PDF by creating an iframe with a blob URL, then calling iframe.contentWindow.print() Library behavior is similar to print-js (PDF iframe print flow) Problem:

When Firefox PDF handling is set to “Open in Firefox”, printing mostly works. When Firefox PDF handling is set to “Save File”, the same blob iframe print flow often fails: print preview shows blank page / about:blank or preview shows an extra trailing blank page print dialog options also differ from normal PDF preview flow What I already confirmed:

iframe src (blob URL) looks valid and similar in both settings issue is reproducible with same PDF data fallback to image-based printing works but degrades UX (different print panel/options, possible scaling differences)

At some point a few days ago I accidentally dragged the divider that separates the pinned and vertical tabs. As a result, for the last few days, I have been stuck with the divider being in a fixed position no matter how hard I try. The problem is that I use collapsed sidebar by default and can't reposition it for the collapsed tabs state, and as a result, there's a mismatch in how many pinned tabs I can see when hovered and when unhovered, among other issues

If possible, I'd love to just reset the position to how it was before, that being that it would show maximum pinned tabs and scroll the normal tabs, and do so for both collapsed and uncollapsed tabs, but I haven't found a way yet

I've tried dragging the divider to the very bottom, but that didn't work either and it'd eventually reset

I'm running Windows 11 Pro on a desktop PC. I have used Firefox "Search by Image" many times and I haven't had a problem in the past. A few days ago the search failed for "some" images and now it fails for any and all images that I drag and drop into my browser. Important: It does work for images on the internet. My problem: (1) I drag and drop an image into my browser. (2) I right-click on the image. (3) I select "Search by Image". (4) I select a search engine. Absolutely nothing happens. I've tried with various images and various search engines. Still nothing happens. I don't think I'm doing anything different than I've always done. I haven't changed any settings in Firefox. Any ideas?

My firefox has been acting weird all of a sudden. Usually when I open firefox it loads all my tabs of the previous session and prompts me to enter my master password. But now when I start firefox, it opens for a brief moment and then instantly closes again. When I open firefox again all I get is a new empty window without any tabs, the password prompt also doesn't appear. So I have to manually open my last closed window to get the old window with all the tabs back (so I guess the window that closes instantly was the proper one) but the master password prompt won't show up. I can't access all my saved passwords in the password manager since I'm expected to sign in but when I click on "sign in" nothing happens - I guess the master password dialog just doesn't show up blocking me out of it. The only solution I have found so far is to go to about:support and clear start-up cache data. When it reopens afterwards I get the working window back, with my saved tabs and the master password dialog shows up - everything works. But it only works for this session, when I reboot the computer I have to do the whole issue again. Opening it in safe-mode also works but I need my addons and since it starts after clearing startup cache I don't think the addons are to blame. It just happened all of a sudden, I didn't install any updates or new version prior to the error.

Can anyone please help me? :(

I'm unable to open my mail.att.net on my HP Windows 11 computer. The screen shifts to Yahoo mail now. For a time I could click on the "small Person" symbol to log in. That now longer works. The session times out without connecting. I've cleaned and deleted cookies and browsing history. The same login problem now also occurs on my Microsoft Edge browser.

The instructions for changing country in built in VPN do not work as after clicking on icon it states open VPN and nothing happens to open it. I am trying to set France as my country.
