When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

Firefox has recently (within about a week or so) begun to crash randomly for me when switching between open tabs. The problem can be reliably replicated with ~6 tabs open, while quickly cycling between them. Firefox has been updated, and the crash still occurs even in troubleshooting mode. The most recent reported crash is Crash ID: 54793083-0841-470c-ae8a-687030240105. The flagged 'Crash Reason' is EXCEPTION_ACCESS_VIOLATION_WRITE

Is it possible to combine history/bookmark files? Firefox has truncated my "History" to 15 days and the only option I see to get elder entries is to combine a backupped history file with the current one. An easy-to-use tool for this task would be welcome. I did not change my config options after the update to 121.0.1 (64-Bit) (Windows 10pro) but I think I had the total history (from years) before the update. My current Options related to this topic are: browser.history_expire_days false places.history.expiration.max_pages false places.history.expiration.transient_current_max_pages 501234 privacy.clearOnShutdown.history false privacy.history.custom true history (*) Boolean Number String

I already sreened Help files of this Forum concerning lost history data but they all do not give sufficient answers or I do not understand them (as a German user). Thanks. Martin

I run Firefox 121.0 on Windows 10 Pro. I use a VPN (ExpressVPN) and normally run Ghostery and uBlock Origin. When I log onto Townhall.com and enter my VIP credentials all is fine. However, when I read an article I should be able to access the comments. I cannot in Firefox and this is something that has occurred about 3-4 weeks ago. For years I have not had any problem like this with Firefox.

I tested VIP access with my iPhone - works fine. I tried Vivaldi - works fine. I tried Chrome - works fine. I try Firefox - fails!

I ran Firefox in "TroubleShoot" mode, with all add-ons turned off and it also fails. Even when I run Vivaldi I have Ghostery and ad blocking turned on, but Ghostery does allow townhall.com on their whitelist.

I've send emails to Townhall.com and am not getting any responses. However, I was having the issue with all devices but all have been fixed except with Firefox. So, I have no idea why this is an issue with Firefox but not with any other device.

Any thoughts?

Is there any way to rotate between different screen sizes option using shortcuts keymaps which appear during "responsive design mode" is on. I found extensions which resizes whole browser & they helps. but it also causes developer tool to resize along with browser which hinders me to see different css properties. so i am looking for a way to rotate only screens.

"Responsive Design mode" is what turns on when we press ctrl+shift+m.

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Hello,

I have not had any problems with Firefox sync and passwords until recently. I used to use Firefox on desktop, on an iPad, and on an android, with no issues accessing my passwords. Recently I replaced my android phone with an iPhone, and after signing onto Firefox sync on said iPhone, the list of my passwords was accessible on the iPhone, but when i used it for auto-fill, it would only load the username, but not the password. This caused no issue with Firefox sync on desktop or iPad however, so I just let it be. However, after 3 months of no issue, when I open both my iPad and desktop today, all my old passwords are gone, and replaced with the few passwords I directly saved with Firefox on my iPhone.

i have tried restoring my old Firefox profile using backup software to access older files, but I am unable to regain my passwords this way. I have tried using profile data from several date ranges and that has not helped either. The issue seems to lie with Firefox sync with iOS, but I am at an absolute loss on how to resolve this, so any help at all would be much appreciated.

I do not care about MSNBC, I just want to know why I cannot live stream on MSNBC in case I run in to other channels that may not work I would like to solve the issue or I guess I can just uninstall Firefox and call it a day if it is just the browser.

The audio does work, but the video is the start up or splash photo for MSNBC

Firefox will stream on NBC and I can stream MSNBC using Chrome and Edge.

I resent all of the setting in Firefox to default, and I turned off all of the extensions.

Hi! After recently following the upgrade path from FF v52 to the most recent FF version, I find that logins in logins.json did not carry over with the upgrade. Out of 555 logins, only 44 appear. (I suspect these may have been imported from Chrome, since FF also imported my Chrome bookmarks without acknowledgment.) I see that the old logins are still in logins.json, and logins.json appears to be valid JSON when opening with FF.

I tried ensuring that logins.json, key3.db, and key4.db had matching timestamps, but that didn't correct the problem. I tried replacing key3.db and logins.json with copies from a backup of the v52 profile (it has no key4.db--is key3.db no longer used?), but then zero logins appeared (why I think the ones that do appear may originate with Chrome). I tried exporting logins to CSV, but it only captured those 44. I can see the logins are in logins.json, but the passwords are hashed/obscured.

I have profile backups, but I don't find a way to import the logins. (If I had to make a wild guess, I'd say the upgrade might have ignored my key3.db that paired with my logins.json, and created a new key4.db full of Chrome logins instead.)

How might I recover my logins from either the in-use logins.json or from my profile backup?

Thank you!

OS: Linux Mint 21 Browser: Firefox 121.0

There are a few sites I frequently use that popup windows that can't be blocked or moved out of its lower right position. It most cases it blocks important text due to the screen/font scaling I have to use.

My browser privacy settings are set to "Strict".

Autoplay setting is: "Default for all websites: = Block all Websites"

The popup window banner reads "Trending Videos". No video or audio plays and the window is black with the error msg: Sorry, the video player failed to load.(Error Code: 104153)

There is an "X" button on the right hand side of the banner that does go into focus when I hover the cursor over it, but clicking on it does nothing.

I have tried various popup blocking addons but so far none have been able to stop these popup windows.

Suggestions please!
