I inadvertently changed the FF Bookmarks OPEN WITH app to Itunes!

I was restoring FF book,marks from 1 desktop to another. Now when i Back up my Bookmarks, it shows TYPE as "Itunes" on my Desktop FF bookmarks folder.

How do i get rid of Itunes for FF bookmarks?

Appreciate your help. Thanks.

I've just rebooted and I've lost two windows with thirty tabs, or something.

When I started Firefox, there's nothing in the Recently Closed [Tabs, Windows]

Reading online, I see that Firefox should be writing some files to the sessionstore-backup directory, like these:

recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session) recovery.baklz4: a backup copy of recovery.jsonlz4 previous.jsonlz4: the windows and tabs in your last Firefox session upgrade.jsonlz4-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

, but I only find recovery.jsonlz4 and recovery.baklz4 and both are tracking current time, which means they are getting data from the currently opened Firefox.

These are the only files I find in this directory.

Where are the other files supposed to have gone?

why always my mozilla broswer keeps crashing i am worried about this i have reported this many times but no response I request you to find some solution for my problem.

Hello!

I'm having an issue with Netflix, i am unable to play anything there at all. It always shows a message saying "firefox is installing components needed to play the audio or video on this page" and refuses to load anything, showing an error, F7701-1003.

After some investigation, i found out that the issue is with Firefox not loading "Widevine Content Decryption Module provided by Google Inc.". I have seasrched and tried several troubleshooting processes, and was unable to find a solution. Refreshing, reinstalling, manually deleting the profile folder, all fails

After the second to the last update to Firefox I started experiencing an information pop up message "Could not determine any profile running in backgroundtask mode!".

Is there a fix for this?

Thank you.

When I click on an article or any link in Outlook, I get an error message that says, Your organization's policies are preventing us from completing this action for you. For more info, please contact your help desk. I'm not an 'organization', just a user and obviously there's no help desk to contact, so I thought I'd reach out to see if someone might have a solution to this problem. I have already made sure that my default programs are set to Firefox for my browser and Outlook for my email and made sure all the defaults are selected. I have also run a full windows scan program which came up without any errors and I have run a registry scan that fixed every identified error. I'm still getting the same error message and the only way for me to open up an article or a link from an email is to 'copy hyperlink', open up a new tab in Firefox and select Paste and Go, which is driving me nuts and wasting a ton of time. I don't know what else to do at this point. I did find a document on the internet that has what it says is a method to resolve this exact error message problem, but the instructions are specific to Internet Explorer, not Firefox. I'm hesitant to find those same tools on Firefox (which is quite possible, though some of them are in different places on Firefox than they are on Internet Explorer). My concern comes with the fact that the final step will 'reset' every setting to it's default condition, so it seemed like a good idea to try to get some expert help before I perform such a drastic action. Also, I'm also making the assumption that if I did do a complete reset, I would be able to restore Firefox back via my most recent System Restore and it would bring back all my customizations, browers add-ons, personal settings, home pages history, cookies, privacy settings, etc. - but I'd like someone to weigh in on this. Thanks for any help anyone can provide.

Hi!

I want to use my own unsigned addon with my daily browsing. But I found out that firefox hates it's user base by making xpinstall.signatures.required option in about:config only available to dev builds.

If I use firefox dev build will I loose on performance? For example is it compiled with debug symbols that slow down code execution? And if so, is it somehow possible to get the release version of firefox where xpinstall.signatures.required is set false so that I would not loose because of dev build?

So I can not play audio from any website in firefox. I updated, refreshed, used troubleshoot mode, and unistall & reinstalled. Nothing works. I know it is not my PC because the sound works on every other app, just firefox wont play audio PLEASE HELP

Some features on the FT web pages no longer work. E.G. the site allows you to share articles with other subscribers and non-subscribers. This option no longer appears on Firefox. This facility is there on my iPad, (Safari) and when I contacted the FT they said some java script had been disabled and I could try Chrome. Pleas advise. Regards Hasan Choudhury.

I just installed Firefox. I looked at a few articles here that seem to be relevant to my issue, but they didn't get me anywhere. I just want to export bookmarks from Chrome to Firefox.

TIA SweetTasha

Since the upgrade to Firefox 104.0.2, the only option when printing is to select "Save to PDF". All other apps can printer to any of my printers. I have to save as a pdf then print the document using the PDF viewer. I have HP4100 & HP9025 printers on my network, that all other apps can see and print to. I've refreshed Firefox & re-installed Firefox but the problem still persists. The System's printer dialog shows that both printers are available and changing default, or reinstalling the printers makes no difference. OS is Ubuntu 22.04.1 LTS.

Screenshots show the printer window in Firefox, and the Printer Settings from the OS Settings window.

I have tried searching all self help topics. I have tried all available settings options. I have upgraded to the latest version 104.0.2. However, nothing seems to fix my problem which is that Firefox will not restore my previously open tabs when I reopen it. This problem started a few weeks ago. I have selected [Open previous windows and tabs] I have selected [Firefox will remember History]

Can you please help

Thanks Fred

I've lost the ability to use site-based hotkey shortcuts. For example, if I pull up Google Docs, if I type a statement and try to bolden the text with Ctrl + B, I get the Bookmark sidebar instead. Ctrl + I for italics? Instead I get page info. Ctrl + U to underline? Instead I get a wall of coding. This issue is a consistent thing on all websites, for a variety of hotkey commands.

I can't find where I can change, or turn off hotkeys in general, the last three hours of scouring the internet, including the FF forums, have been no help. I can't tell if this is a setting I can't find, I change with an update, but whatever it is, it needs to be reverted. I'd very much prefer not to switch browsers over an issue that should be a changeable setting.

For some reason when writing an email on outlook.live.com, the check spelling feature disappears from the right click context menu and spelling errors are not highlighted anymore. I don't have a known time that it does this, but it happens minutes after the outlook.live.com page was first loaded and it doesn't matter if I was reading or writing an email before I started writing an email. A refresh of the page fixes the issue temporarily.

Hi! In Windows 10 new version 104, .pdf are opening as a download as well as a file. I checked settings, and it still shows that .pdf should open as a file. How do I keep it from becoming a download?

See image to see what is happening. This did not happen with any of the older versions.

Thank you so very much for your help!! T.S.

Ending in 52.X, one of the old add-ons called mkiosk was really wonderful. It had all sorts of configurable options including one that was critical to my free application of Firefox-ESR used by some non-profits. That feature was a timeout such that if the user walked away while not in the "home" web page, a configurable parameter returned firefox to that "home" page. I have not found this feature anywhere else. Unfortunately, installing 52.X on a standalone current bullseye version for the Raspberry Pi is turning out to be problematic. Is there any way to resolve this issue?

Some ideas: 1) Find out how to make Firefox accept an obsolete add-on 2) Fins out how to tell with an external program what page Firefox is on and by periodically polling it, kill and restart Firefox if the time on that page exceeds a certain limit. On the old mkiosk, I set 5 minutes.

Any help here? I'm not a json person so even editing the old mkiosk is beyond me.

A Trojan was detected in favicons.sqlite-shm by BitDefender, the report said it blocked it (see screen-cap). Soon after, I wasn't able to load Firefox, Opera Browser and Thunderbird. Tying to access them would start a popup dialog box stating that"Firefox is already running" and I'd would be asked to either cancel or stop. Pressing either option wouldn't allow access to Firefox etc., I had my computer scanned professionally and was told they didn't think the Trojan was still active and they managed to restore access to Firefox and Thunderbird, this took 2 hours.

I remain unconvinced my computer is free of the Trojan for various issues, including a corrupted winload.efi file (I have already attempted and failed to fix this) that won't allow Windows Defender to scan in Offline mode. Various other issues such a slow applications and occasionally flickering screen suggests the Trojan might still be active.

I'd greatly appreciate if anyone has information or experience dealing with particular issue.

Scans such as, Kaspersky, Malwarebytes, Bitdefender, etc. have been run and found nothing.
