After upgrading from Firefox version 149 to version 150, I am no longer able to log in to Facebook using Firefox, although login attempts are successful in other browsers. Could you please clarify whether this issue is unintentional, or if there is a strategic reason behind it?

In the past, I was able to freehand highlight PDFs that did not recognize the Text. I was using this function this week; maybe the newest Firefox update is at fault. Without this, half of my documents are not really usable in Firefox. Everything else works. If it recognizes the text, I have no problems; the pencil tool also works just fine.

The threads.com website looks very strange. In all other browsers it displays fine, but Firefox shows enormous size icons and barely visible text, with no formatting. Please see attached screenshots. Tried to clear cache, cookies, etc. - nothing worked. Please help!

Hello, I'm wondering if someone help me troubleshoot why the normal or recommended password files recovery isn't working in my case, because it isn't. I've spent 2-3 hrs this evening trying to follow the normal/recommended protocol for recovering previous passwords but it's just leading me in circles, sans passwords being recovered. What usually happens is every couple years either my bookmarks file gets completely lost or - this is new - in this case my saved passwords are gone (possibly corrupted, I'm not sure). I think something might've been corrupted or reconfigured (I hope not "lost" entirely), attempting to install and use the Beta VPN. Ultimately it was just too difficult to get it to work simultaneously around Norton360, which I decided was probably better to just stick with for now. Out of curiosity, I was attempting to get the Firefox Beta VPN installed last night (and operational) and I think that may have been when the previous data was lost or reset somehow. I tried following the basic procedure to reboot FF from previous folder backup (to desktop, "Old Firefox Data"), but that merely reproduces the same "empty" passwords page when I try to open up my saved passwords. Neither of the 2 previous App Data locations seem to help rebooting from ("default" or "default release"), and I'm hoping against hope, at this point, that one of those old JSON files has all my passwords still in it, uncorrupted, but there are so many, I have no idea how to find my way to the correct one. In any case, my FF saved passwords were still fully available and working as of only a few days ago, probably this last Sunday evening, today is Wednesday of the following week. My previous saved Bookmarks are apparently still intact, and auto-loading as normal, regardless of which of the previous user profiles I'm rebooting FF with. If anyone can help me, I would really appreciate it.

After I updated to the Version 150.0, everytime I want to check something on the mac menu bar, the whole page gets pushed down. Only the toolbar used to drop before the update. Thanks for any help in advance.

The newest update of Firefox makes my Windows Settings window pop up, and demands that I allow Firefox to access my location and or device.

This is unacceptable. That setting is greyed out on Win 10 machines....FIX FIREFOX. I am not buying a new computer just to use Win 11, which is nothing but spyware.

A new Facebook link can open Firefox and work, but subsequent Facebook links result in a failure. The error message is "This content isn't available right now When this happens, it's usually because the owner only shared it with a small group of people, changed who can see it or it's been deleted."

The Facebook links work with other browsers.

Restarting Firefox begins the cycle again. This has become a problem just in the last month or so.

I’ve been experiencing an issue where dragging a URL or text from Notepad++ into Firefox causes the text to be removed from Notepad++. It behaves like Firefox is requesting a MOVE operation instead of a COPY. This only happens with Firefox, dragging the same text into Vivaldi, Chrome, Edge, etc. does not delete the text.

Here’s everything I’ve already tried:

1. Verified it’s not a Notepad++ setting Disabled “Multi‑Editing” in Notepad++ Restarted Notepad++ Confirmed the issue only happens with Firefox, not other browsers

2. Tested Firefox Safe/Troubleshoot Mode Launched Firefox in Troubleshoot Mode (no extensions, no themes, default settings) The issue still happens there, so it’s not caused by an extension or add‑on

3. Created a brand‑new Firefox profile Went to about:profiles Created a completely new, clean profile with no imported data Tested dragging again — the issue still happens even in a fresh profile

4. Reset and recreated drag‑related Firefox preferences I checked and/or reset the following in about:config: ui.dragThresholdX → recreated as Integer = 16 ui.dragThresholdY → recreated as Integer = 16 dom.event.clipboardevents.enabled → set to false browser.drag_out_of_frame_style → set to 0 browser.search.context.loadInBackground → false browser.tabs.searchclipboardfor.middleclick → false browser.urlbar.update1 → false widget.disable-native-drag → true Restarted Firefox after each change. None of these resolved the issue.

5. Tested modifier‑key behavior Holding CTRL while dragging does prevent the text from being deleted → This confirms Firefox is treating normal drags as MOVE instead of COPY.

6. Verified it’s Firefox‑only Dragging the same text from Notepad++ into Vivaldi, Chrome, Edge, Word, Notepad, etc. works normally Only Firefox causes the source text to be removed

I'm at a loss of what the issue can be or where to go from here or if there is no fix at the moment.

I went into firefox security in preferences and deleted some of my certificates and now I can't log into or get on almost all of my old websites...is there a way to restore my original settings???? Thanks

Dell Optiplex desktop, Linux Mint Mate 22 OS. Currently updated to FF 150.0. For several months, this machine has failed to load bookmarks, approximately half the time. Banner message displayed advising user to load bookmarks. Closing and restarting FF usually (but not always) corrects this. Also, last month or so, bootup displays single window, even if there were two or more on previous shutdown. In settings menu, FF is set to re-open previous windows and tabs. Also on boot, this machine takes much longer to open FF than an older Dell Inspiron laptop, which is otherwise slower than this desktop. When FF icon selected in desktop, just before it opens, the tray flashes the missing extra window but it is not shown or available in the tray and does not load.

The two machines are set up identically, both in FF settings and with the same add-ons- Privacy Badger and uBlock Origin. Just looked in Synaptic of both machines and the laptop shows two FF items as installed- FF 150.0 +linuxn The FF Web Browser and FF-en locale English language pack. The desktop Synaptic shows no FF items installed (!). The laptop runs as expected, opening FF with all windows and bookmarks. Both machines received FF 150.0 via update manager.

Hi this can anyone shed anylight on this please? I was using Facebook earlier today with no problem then now it won't run nor open yet it runs fine in Google Chrome. I've cleared out the Cookies ect and re-tried but its not pitching anything.

Many thanks Rob

My copy of Firefox updated about 1600 local time yesterday. At this same time Facebook could not be accessed, just get a blank page. Tried clearing history, but still not working. Windows 11.

Just installed 150.0 (64-bit). Why did it reset my FF🤬🤬🤬🤬 Current theme was reset to a previous theme. And several previously used extensions were reinstalled. WHY!!?
